During the preliminary accident investigation, German authorities informed the Danish Accident Investigation Board that the Learjet’s pilot did not possess a valid German pilot certificate. The passenger aboard was not a pilot, which meant the aircraft was operated in violation of its certification, which requires two certified pilots aboard the aircraft at all times.
The Danish accident report said the “wreckage and the wreckage trail pattern were consistent with a low forward airspeed and a steep descent stall.” The pilot was on final approach to Runway 29 at Bornholm, where the winds were reported as 280 at 19 knots, gusting to 29 knots. Moments before the accident, the pilot declared an emergency three different times.
Investigators also found four of five fuel tanks empty. While the fuselage tank contained 42 gallons of fuel, the fuel transfer and cross-feed valves were closed, preventing its use. German aviation authorities also said the Learjet’s registration had been cancelled in 2009 and that the latest valid airworthiness certificate expired in March 2005.
