The Aerotoxic Logbook (ATLB) in English (EN)

The problem has been known since the 1950s - roughly 70 years and nothing has ever been done about it.  The air in the cabin is still ‚bled off’ (the engines) in airplanes - with the well-known possible consequences for flight safety and health, in particular that of  flight crew. We have the cultural history on 'Flying is safe' and the ongoing problems investigated at www.ansTageslicht.de/cabinair (EN).

Although the cabin air is 50% re-circulated in modern aircraft types, the basic problem remains unsolved. With one exception: the Boeing B787.  This is/was also the state of knowledge at the first big conference on this topic in London in September 2017. The presentations can now be viewed here: www.aircraftcabinair.com  

There are many reasons why no solutions are found: the targeted influencing of scientific discussions, the airlines’ economic interests, the links between politics and air transport industry and other reasons.

The ‚Aerotoxic Logbook’, launched in January 2017, is a first comprehensive documentation addressing the problem of potentially contaminated cabin air (www.ansTageslicht.de/Kabininenluft - German) and documents what is happening in this area.  Or, what is not happening. And why not. This German language blog (www.ansTageslicht.de/ATLB) is now also available in English and can be accessed directly via this permalink: www.ansTageslicht.de/ENATLB. And you should also have a look at www.ansTageslicht.de/fume-event-files - an "ABC" under permanent construction.

The information we collect in German is translated by Bearnairdine BEAUMONT who operates the network www.aerotoxicteam.com  and the blog www.aerotoxicsyndrombook.com/blog.

With the ‚Aerotoxic Logbook’ we want to achieve international networking,  bringing together all initiatives and activities to communicate about this unsolved problem and to initiate solutions. At the same time it is a scientific experiment: What must happen before a problem is addressed?

Other initiatives providing information on the contaminated air issue you can get here (right side).

Fume Event and Consequences: topic at the "Medical Experts Council for Occupational Diseases"?

That's what we want to know: has the committee ever dealt with this? The problems have been known for around 70 years as is shown in our chronology:  A Health Problem becomes a Certainty: Chronology of the Aerotoxic Syndrome (actually in German, forthcoming in EN).

We have issued a press inquiry to this panel via the Federal Institute for Occupational Safety &Health, which conducts business for the "Medical Experts Council for Occupational Diseases" on which 'leading' (meaning: influential) occupational physicians sit and advise. Their task:

"The review and assessment of the state of scientific knowledge with a view to updating existing or new occupational diseases to the Occupational Diseases Ordinance.  The Advisory Council gives recommendations and issues opinions to the Ministry on the basis of existing information."

We are curious how "sighting and evaluation of scientific knowledge" will be determined in this case. And we will report.

"Fume Event Consultation" in Göttingen (DE) apparently finally shut down

It was closed once before: in mid December 2016 until May of this year. Now it is closed down again, and apparently this time its final. Not only new patients are no longer accepted, now even the 'regular customers' no longer receive a follow-up appointment. This has been indicated by the patient initiative p-coc.com. They give a whole series of recommendations:

  • What should be investigated after a fume event  in addition to the biomonitoring and
  • what one should pay attention to regarding what is proposed by BG Verkehr’s ‚D-doctors’ ( ed: first port of call for work place accident injury victims)
  • who are located near the airports,
  • and how to possibly enforce a necessary investigation; if need be with the help of a legal adviser. 
  • Or which additional medical measures are necessary and much more.

The exact reasons of the closure  are not known.

However, it is known that BG Verkehr wants to carry out its own human biomonitoring investigation series, at the DGUV, or its IPA institute, and wants to concentrate everything there -  instructions to this effect have been given to all D- physicians to have such examinations carried out only within their own BG or DGUV network (IPA Institute in Bochum).

Since the beginning of the BG's own 'study' the payment of costs for examinations at the apparently unfavorable Fume Event Consultation Clinic in Göttingen have been refused. It is well known that the senior physician and occupational physician PD Dr. med. Astrid HEUTELBECK has come to other results and conclusions as to whether and how fume events can (or do) affect people's health.

Whether all this is in accordance with "free choice of doctor" in Germany, is - for the first time - undecided. Due to these restrictions, the P-COC patient initiative believes that "an independent quality assurance is not given." 

That's because, according to reports from sufferers, "the D-physicians only, if at all,  offer human biomonitoring;  further diagnostic testing is not carried out, referrals are denied, and furthermore the results of the IPA's proof-of-substance assessments – have never been to given the affected persons. The hitherto still valid medical standard procedure of the BG after fume events has not been used since the beginning of the study. "

The ATLB will endeavor to obtain a substantiated justification from the UMG. And will then report.

A summary from the Lufthansa staff meeting November 20th 2017, topic: FUMES 

There were significantly more interested people present than expected.

Of course, management representatives were also attending in order to present their point of view.

In short the highlights from my point of view:

The lecture by Professor Dieter Scholz, an expert in aircraft systems technology from Hamburg University of Applied Sciences. He showed that small quantities of engine oils ALWAYS get into the air, even if the seals are working as intended.

  • He further reminded that the engine oil can cause nervous system effects according to the warnings on the oil packaging (as they were in place up to 2004).
  • There is even the possibility that chemicals from the oil mist get into the on-board water system because in most airplanes the water tank is pressurized with bleed air. This means in plain language that our coffee and tea on board could also be affected.

If you are interested in details, you can read the lecture here: http://CabinAir.ProfScholz.de 

Frequent questions coming from the audience:

About repeated fume incidents involving the same aircraft over and over  - again management officials said they did not know - to which the audience reacted with a great deal of displeasure - but they want to get information ...

When asked why not after such incidents’ the entire air conditioning is cleaned, or when that would be the case,  rather evasive answers were given. I.e.: one can not clean the air conditioning after every ‚smelly oven’ incident - after verified fume / smell incidents’ this would of course be done.

We know that this is definitely not the case - the complete cleaning of an a/c system can only be incorporated into a ‚D-check’, where all cabin side panels are removed and access is provided to the air ducts. However a ‚D-check’ which involves long ground times (several weeks). Have a look at www.lufthansa-technik.com/en/aircraft-maintenance 

But, as we can prove, most fume-aircraft go back into service after only a short ground-time without thorough cleaning of the air-conditioning system.

The management emphasized that there are HEPA/carbon filters in the recirculation path of the air conditioning system. They acknowledged that these are installed only on a few models. E.g. all Lufthansa aircraft of the A320 family they said are equipped with such filters. On other aircraft there are HEPA filters that can only filter specific particles, i.e. virusses and bacteria. VOCs are not filtered out by HEPA filters.

A sustainable solution needed more research and time  (they said) ...

The problem has been known since the 1950s. How much more time do you want to take at our expense?

Then they tried to appease us, or shine their light, saying that Lufthansa is already doing more than required by law.

Is the responsibility being shifted to politics?

Just because legislature does not demand anything, the employers are not dismissed from their responsibility when it comes to the integrity of their customers and employees!

The unbelievable behaviour of some clinics in airport vicinity was addressed, as well as the lack of understanding how the employers’ liability insurance association (BG) deals with sick colleagues.

I have not heard of any recognized cases of long-term ill-health victims - only (acute) cases  from a few days to weeks are recognized, which are considered to be ‚completed’ after the crew member returns to flying.

Another issue was the inadequate amount of smoke hoods onboard and that it would be desirable for each crewmember to have one available.

Captain Raimund MÜLLER who spoke for the management tried to give us an explanation such as, that the smoke hoods are only to be used after specific instruction from the cockpit ... upon which loud and heated protests arose from the audience.

So you see – there was some ‚fire’ in it ...

I was really enthusiastic about the many colleagues who consistently asked critical questions on the topic and who refused to be intimidated by the presence of management.


The loud and approving applause of all colleagues at the end, will maybe get one or the other LH representative thinking ...

ZEMBLA documentation in NL poses questions in parliament

The first part of a documentary "Poison in the cockpit: the silence contract" shown the day before yesterday (8.11.) triggers first reactions. The left-liberal party "Democraten 66 (D66)", which has been sitting in parliament since 1967 and has been involved in government coalitions several times, is now asking the government its first questions:

 

  • "D66 would like to know from Cora Nieuwenhuizen, the Minister of Infrastructure and Water, what there is to do to make sure that there are no pilots in the Netherlands who suffer from symptoms of the aerotoxic syndrome, with symptoms such as headache, balance disorders and slow reaction speed.  D66 raises the question after ZEMBLA’S broadcas : "Poison in the cockpit: the silence contract".
  • D66 wants to know from the Minister how this is possible. The party also wants to know if the inspection commitee already knows how many pilots are suffering from the disease.
  • D66 Chamberlain Jan Paternotte doubts the independence of the advisory group following the broadcast of ZEMBLA. He asks whether the minister also believes that the advisory group should draft independently and provide it with independent scientific advice.

Now a Belgian team wants to interview the French pilot Eric B. (also fume-event injured), who has lodged a criminal complaint in France.


Here are some links from Holland and Belgium:

Dutch TV channel ZEMBLA picks up Fume Event Incidents and Gagging Order Clause

KLM attempts to sanction or threaten its pilot, Willem FELDERHOF, with a € 300,000  fine and damages in the event that he voices : "his opinion, his views and the facts regarding the air quality in KLM airliners in connection with his health condition, employment conditions and ‘aerotoxic syndrome’”, in public.

Regardless of this, information with the hush-money clause  has reached the Dutch TV broadcaster  ZEMBLA, who took up the subject and published it on November 8th in the third program. Part two is scheduled for November 15 at  9:15pm on NPO2.

50 fume events in 1 month at BA

The English Times reports about a leaked document, from which this fact emerges. However, the journalist's report has been severely cut – due to the very detailed coverage of sexual harassment cases in the British Cabinet: British Airways warns pilots of 'fume events'

BFU’s resounding silence, yet again - unlike Switzerland

"The task of the BFU is to investigate accidents and serious disruptions during the operation of aircraft in Germany, and to determine their causes."

Says the German BFU about the German BFU as far as their tasks are concerned. However, the BFU has their own opinion and their own defined standards  in how they see a "serious disruption", as Austria's aviation magazine "Austrian Wings" found out.

The editors had taken the opportunity to find out about a fume event on a German Wings aircraft (September 30) to make inquiries at the BFU. Four of the flight attendants were "injured", two of them even had to be hospitalized. They also had to be supplied on board with (pure) oxygen and were then on sick leave for several weeks.

For the German BFU:  no "serious incident".

Austrian Wings wanted to know more from BFU, but received the usual standard answer:

"As you are probably aware, the legal basis of the work of the Federal Bureau of Aircraft Accident Investigation (BFU) is the Regulation of the European Union, EU VO 996/2010 and the Aircraft Accident Investigation Act, FLUUG from 1998, as well as the ICAO Annex 13. According to the BFU it is not a serious incident or an aircraft accident, so there will be no investigation by the BFU of these reported events. "

The Austrian Wings’ editorial staff confronted the BFU regarding their contradictions, because according to the definition of the BFU,  a "serious incident" can be defined as such when crew members have to resort to oxygen or are off sick afterwards following incidences.

BFU reply this time: none.

Different apparently in Switzerland. The Swiss Accident Investigation Board (SUST) recently defined a similar case as a "serious incident" although nobody was "injured" or hospitalized.

The complete original Austrian Wing report can be read here : Von "Unfällen" und "schweren Störungen", die keine sein dürfen.

Lufthansa and the topic 'Underreporting'  

We had given up on it: to document when and how often so-called fume events happen. After three months (1.1 - 31.3.2017) of regular reporting of (only) known incidents we realized that there is systematic underreporting. A continuation of such documentation would be inefficient since there are other’s who do that. For example Aviation Herald’s Simon HRADECKI

Today we are making an exception and are picking up Aviation Herald’s report of the day : 2 incidents’ that are closely related: Lufthansa flight LH-447 with Boeing 747-400, registration D-ABVW, on the 20th. / 21st October.  On the way from Denver to Frankfurt a fume event happened even before the aircraft  took off: when the engines were started. "Technical problems", they said, plus an hour waiting time, resp. delay. Passengers noticed, that all doors remained open during this time - apparently to 'air' the plane. 

Straight after take-off the typical smell appeared again - the flight was continued. As one knows by now: upon beginning of descent the unmistakable smell appeared again. Members of the crew, but also passengers complained about typical symptoms: neausea, headaches, irritation of the eyes or vision issues.  

Upon Aviation Herald’s inquiry, the BFU had to admit that – as so often -  they knew nothing of this incident. Nobody had reported it.  It became known, that on the same aircraft, on October18./19. , two days before  this incident, a fume event had already occurred. With the same consequences for passengers and crew. This fume event however, had become known to the BFU.  But as usual in these cases: because the passengers had not been informed about the actual reason, apparently no one had gone to see a doctor - not even the crew. 

So the airline can be 'satisfied': there is no medical documentation for either incident which the Aviation Herald classifies as "accident" (rather than incident). So no medical proof of any consequences. 

More about that at Aviation Herald.

Tim van BEVEREN, dismissed by many as a "conspiracy theorist"

visited ansTageslicht.de, as part of the research about cabin air and the role of occupational health medicine.

The pilot, journalist and film maker told us about  how his documentary Unfiltered Breathed In, which has since been aired at many film festivals, was made.  And why it can only be seen in cinemas. Respectively why it was not broadcast by WDR. Which was originally planned.

But many strange things had happened.

We wrote them down. And, for editorial security reasons, we will research them again. And then publish it. As a contribution to the topic: the truth about independent "public service broadcasting".

We ask for your patience.

"Fume Events: Airlines in state of alert"

This is the heading of an article on the DocCheck news site, which now is also dealing with the problem. It seems that the topic has now also arrived at this medical network.

October 19th, 2017

fuProblem now also on FOCUS ONLINE

After the airing in "Markt" by German TV NDR at the beginning of the week, in which contaminated cabin air was a topic (see entry of October 16) and DIE ZEIT who reported today, FOCUS ONLINE is now also present and has an anonymised affected flight attendant report about several such incidences: Toxic fumes on board: a flight attendant who already experienced this.

Apparently the subject is picking up momentum ( a little). 

October 19th, 2017

The weekly newspaper DIE ZEIT is dealing with the topic

Freelance journalist Petra SORGE published a detailed report on fume events and the consequences for those affected, in particular flight attendants and pilots, in issue No. 43/2017 (pages 30 and 31): "Poison in the cabin?" (Gift in der Kabine?)

SORGE was able to interview several pilots and flight attendants, all of whom reported similar symptoms summarized by the term "aerotoxic". This term was coined in 1999 by three independently working research scientists and physicians from France, the USA and Australia, who got together to find a fitting terminology for the symptoms.  (more about this in 'Health problem becomes certainty: Chronology of 'Aerotoxic Syndrome' - actually in German).

Many airline employees,  especially those who are affected by it know about the problem. Passengers not. The pilots are instructed not to inform the customers in case of an incident. Whoever does it anyway must probably expect "personnel measures", Petra SORGE quotes Jörg Handwerg,  the spokesman for the Association Cockpit (VC).

This is also due to the fact that the airlines would not only shy away from the conversion costs, but also possible litigation, which for example in USA, where high claims for damages are standard could be expensive. "That is why airlines, but also manufacturers, professional cooperatives and politics will continue to express their doubts, deny facts and produce studies." the journalist quotes the speaker of VC.

Fume Event - smell event: Airbus A319 needs to make an emergency landing.

It has only now been made public that a fume event took place on an easyJet plane (registration: G-EZNC) on October 3rd, which was on the way from Palma / Mallorca to Luton and had to land in Paris: several passengers and flight attendants, but also the co-pilot had become ‘unwell’. After the unintended landing, 6 paramedics were in attendance to provide the passengers and co-pilot with first aid. The latter received pure oxygen. This is reported by the ‘Aviation Herald’.  

Nothing unusual, because, as is known, fume events happen regularly, which then are usually belittled or completely denied. The British journalist Andrew GILLIGAN asked the airline whether this was a so-called aerotoxic incident. The answer was ‘no’, that this had only been a simple‘smell event’ and easyJet would not classify such events as ‘aerotoxic’.

However, easyJet had to admit that there was a leak of hydraulic fluid that could have developed a "very small amount" of smell. A ‘technical cleaning’ took place in Paris in which all of the return flow filters were also replaced. The plane had to stay on the ground for more than 60 hours before flying back to London.  Andrew GILLIGAN (@mragilligan) also has a passenger speaking in his article "EasyJet in forced landing as 'smell event' overcomes co-pilot", which appeared in the Times, providing details on the event. 

Some blog comment entries following this report are interesting;  a specialist with the alias of ‘VH-EAH’ posts and indicates that he was one of those people who had been involved in the EASA study (published 2017). He corrected firstly that the landing was not an ‘emergency landing’ and that secondly, the EASA study had shown that such ‘cabin air events’ had no adverse effects on health.  

This shows once again how this  problem is repeatedly downplayed . The fact that this is also done by easyJet is astonishing, since this airline has decided to work with PALL Aerospace  to install new filters which are designed to directly filter the bleed air (see entry of 20 September).

Expert condenses the cabin air problem in a scientific summary  

One who would know and  who’s knowledge cannot be denied has compressed the topic of potentially contaminated cabin air from 3 sides: Prof. Dr.-Ing. Dieter SCHOLZ teaches aircraft design, aircraft systems and flight mechanics at the University of Applied Sciences Hamburg (HAW). He worked formerly at Airbus, so he also knows the practice (not just the theory) and has been dealing with exactly this problem for some time.  

The title of his summary: The air in the cabin of passenger aircraft is not as good as often assumed - background, solutions and implementation thereof (in German)

The so far largest conference on cabin air has come to an end  

The International Aircraft Cabin Air Conference took place at the Imperial College in Kensington/ London over two days (19th and 20th September) and was by far the largest gathering of experts, scientists, affected people and interested parties to date. About 300 people attended, among them about 30 speakers.  

Representatives of the aviation industry were only very sparsly represented - at least officially, but included 2 representatives from PALL Aerospace who, together  with easyJet, want to test a new bleed-air filter system (see entry below). 

Representatives of other manufacturers (Airbus, Boeing) or airlines (Lufthansa, Condor etc.) from Germany for example, were not present, but presumably attended undercover.  The BDL (Bundesverband der Deutschen Lufverkehrswirtschaft)  had also refused to participate in this first ever conference which presented and discussed the latest findings on the technical state of affairs, the problem acceptance and their possible solutions. 

The responisble authorities (BFU - Bundesstelle für Flugunfalluntersuchungen, LBA - Luftfahrtbundesamt, EASA - European Aviation Safety Agency) have in the past and present completely denied the new findings and discussions.  The German aviation industry, the supervisory and regulatory authorities and the political government of the‘Grand Coalition’ still deny – at least to all outward appearances -  the looming problem

September 20th, 2017

easyeasyJet will install filters for bleed air

Of all airlines the low-cost airline has decided to work with PALL Aerospace, which also manufactures the HEPA filters for re-circulated air in aircraft, to install such filters which are intended to keep out contaminants and are supposed to clean the bleed-air tapped from the engines,  in their fleet of aircraft within about one year.  As a result, the potential contamination of cabin air could be further alleviated or even prevented.

This was announced by the airline and the manufacturer at the London conference.

The air in most modern aircraft is first sucked in, then compressed, cooled and warmed again.  During the flight it is then mixed to about 50% with the already existing air (re-circulated air). The air which has been reused to 50% can be purified from hazardeous substances by these ‚HEPA’ filters. The weak point so far: the constant new air stream fed from the turbines. A good graphic is printed in the Sunday Times.

EasyJet’s and PALL Aerospace’s goals are ambitious. However, innovations are not possible without high goals and commitment. During the period in question, they not only have to undertake test flights,  but also have to submit the many applications seeking approval by the various aviation authorities.

The reason is not really clear why a low-cost airline should be first to go down this route. On the other hand, easyJet is currently facing 2 law suits from flight attendants: one in France (criminal charges) and a recent one in the UK.

Strictly speaking, easyJet is not really the first airline to have filters for the bleed-air from their engines. DHL's cargo planes are all equipped with these features: in the cockpit.
