What happened
On January 15, 2012, a Cirrus SR 22 was performing a flight from Paderborn to Brilon, with plans to continue to Kassel. During the initial approach to the Brilon landing site, the aircraft performed two approaches. The first approach was recorded at 98 knots, while the second was at 92 knots. An eyewitness noted that the second approach was too fast, resulting in a hard landing where the nose gear struck the runway first, causing a bouncing motion. The aircraft subsequently veered off the runway onto soft grass.
Later that afternoon, the aircraft attempted a takeoff from Brilon. Shortly after lifting off at an altitude of approximately 20 to 30 meters, the pilot reported a loss of engine power. Upon retracting the flaps, the aircraft lost lift and descended into a nearby field. There were no fatalities and no injuries among the four occupants, though the aircraft sustained heavy damage.
The investigation
The BFU examined the aircraft's Avidyne Engine Data Log, which revealed that the aircraft had been flying at low altitudes for an extended period, undershooting safety minimums. Investigators also reviewed the aircraft's weight and balance, noting that the aircraft was approximately 19 kg overweight at the time of the second takeoff. The investigation also looked into the takeoff performance, noting that the aircraft reached only 46 knots during the takeoff roll and failed to accelerate further.
Findings
- The pilot rotated the aircraft at a low speed and a high angle of attack.
- The aircraft lifted off in an exaggerated flight state and drifted to the left with a drooping left wing.
- The retraction of the flaps reduced lift, causing the aircraft to sink into the ground.
- The pilot's experience on this specific aircraft type was very limited, with fewer than 10 hours of flight time.
- The approach speeds for the earlier landing did not adhere to the manufacturer's recommended values.
