KLM Royal Dutch Airlines carried out a test flight this evening (17 Apr) between about 19.45 and 21:00 hours CEST in Netherlands airspace using a Boeing 737-800. The flight was carried out to establish whether air quality in the atmosphere meets the requirements for safe flight. No problems were encountered during the flight.
The aircraft was transferred to a hangar on landing where it underwent a thorough inspection. The results have been reported to the Transport and Water Management Inspectorate. The Inspectorate will take the decision on whether flight operations are possible.
KLM President & CEO, Peter Hartman, said: "At first glance there is no reason to suspect that anything is amiss. We observed no irregularities either during the flight or during the initial inspection on the ground. If the results of the technical inspection confirm this impression, we are ready to start by returning seven of our aircraft to Amsterdam from Düsseldorf. We hope to receive permission as soon as possible after that to start up our operation and to transport our passengers to their destinations." KLM Executive Vice-President Operations, Ype de Haan, was also on board the flight with Peter Hartman as an observer.
The aircraft flew to 41,000 feet (altitude of approximately 13 kilometres), which is the maximum altitude for this type of aircraft. KLM expects to receive the final results of the technical inspection tomorrow morning.
Passengers are advised not to travel to Schiphol, but to check their airline’s website for the latest flight information.
