Accident Sequence
Shortly after takeoff, the aircraft began to lose airspeed. The pilot checked all controls and lowered the nose in an attempt to maintain speed. Despite these actions, the airspeed continued to decrease. The pilot then lowered partial flaps and executed a straight-ahead landing in an open field. The aircraft slid approximately 75 yards on the ground, during which it penetrated a fence.
Pilot Actions
The pilot reported that all pre-flight, before takeoff, and takeoff checks were normal. When questioned about before takeoff procedures, the pilot stated that he set the mixture at 1700 rpm. The owner's manual indicates that the mixture should be set but does not specify a power setting. According to a Beechcraft spokesman, the mixture should be set at full power. The pilot also noted that all frost was removed from the aircraft before takeoff. The pilot did not check or could not recall the fuel flow or manifold pressure during the event. No mention was made of rpm or carburetor heat at any time.
Post-Accident Examination
A post-accident check of the engine found it to run fine, and no malfunctions could be identified. The density altitude at the time was 2,911 feet.
Operator Statements
The pilot indicated that all pre-flight and takeoff checks were normal. The owner's manual does not specify a power setting for mixture adjustment, but a Beechcraft spokesman stated that the mixture should be set at full power.
