Flight Details
On 6 June 2009, a Cessna CE 182R, registration HB-CFS, operated by Flubag Flugbetriebs AG, was conducting commercial VFR passenger flights from Beromünster airfield. The pilot, a Swiss citizen born in 1953, held a commercial pilot licence with a single-engine piston rating. The aircraft had accumulated 4028:59 hours total time since new and 2582:54 hours on the engine since new, with 859:14 hours since overhaul.
Accident Sequence
The pilot made the fifth flight of the day with three passengers, departing at 10:50 LT on runway 34 right. After a short flight over Lake Sempach, she entered the circuit for runway 34 left. The wind was from the south at 4-8 kt with gusts up to 12 kt, resulting in a tailwind. The landing on runway 34 left was long, touching down after about half the runway length. The right main landing gear wheel was observed to lock. The pilot initiated a go-around by applying takeoff power and retracting flaps to 20°. The aircraft lifted off shortly before the end of the runway and initially climbed a few meters. It then flew over a meadow, progressively pitched up without gaining altitude, and sank back into a field 250 m past the runway end, first hitting with the tail and then the main landing gear. The pilot stated: "I saw that I would not clear the field and therefore pitched the aircraft more and more." A flight instructor heard the engine roar, saw the aircraft lift off, then pulled up and impact in a steep nose-high attitude. The left main wheel and nose wheel were torn off, and the aircraft flipped over onto its back coming to rest 25 m from the first impact.
Injuries and Damage
All four occupants sustained minor injuries. The pilot and front-right passenger's seat belts held; the two rear passengers were not wearing seat belts. The aircraft was destroyed.
Weather and Aircraft
At the time, weather included light rain, visibility about 5 km, clouds at 2300 ft AMSL and above. The wind was from the south at 4-8 kt with gusts to 12 kt. Aircraft weight and center of gravity were within limits. Fuel was found to meet AVGAS 100LL specifications. The engine's technical condition was noted as a contributing factor in the accident.
Investigation
The Swiss Accident Investigation Board (SUST) investigated. The pilot had 1074:57 total flight hours, with 175:35 on type. In the previous 90 days, she had flown 6:52 total and 6:07 on type.
