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 (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:  

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 ( - German) and documents what is happening in this area.  Or, what is not happening. And why not. This German language blog ( is now also available in English and can be accessed directly via this permalink:

The information we collect in German is translated by Bearnairdine BEAUMONT who operates the network  and the 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?

Judgement of the Labour Court Cologne

It is now known that two flight attendants who claim to have suffered injury to their health because they were exposed to cabin air contamination for 45 minutes, lost their case before the Labour Court in Cologne: They claimed damages because their airline acted "intentionally". In concrete terms, such an incident had even occurred the day before.

The airline and the judges argued that the aircraft operator subsequently undertook a technical review and therefore no longer could expect that a new incident would occur the next day. Therefore, intent could be excluded and only in such cases the employer could be held liable according to § 104 SGB VII.

Therefore, the court did not have to examine whether there was a scientifically justified connection at all.

We are currently trying to find out what exactly the technical examination consisted off, e.g. whether the manufacturer’s instructions in the operating manual were followed, or whether - as is usually the case - it was just a small mini-check.

If there are clear recommendations or instructions in the operating manual but no action has been taken, the argument "no intent" would be untenable.
