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.
