Probable cause
The pilot's lack of familiarity with the aircraft, his lack of understanding of the electrical system, and a premature precautionary landing. Contributing to the accident were an alternator failure and the resultant false readings of the powerplant instruments.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot of the Beech A36 was flying on top of an overcast when he noted that the readings on his engine gauges were dropping. He determined that the alternator had failed and was unsuccessful in his attempt to use the standby generator. He then dead-reckoned to a let-down through the clouds at Rawlins, WY, and landed short of the runway when he believed that the engine was not producing adequate power.
