Probable cause
the pilot's failure to maintain clearance with trees. Factors in the accident were the trees, the pilot's operation with known deficiencies in equipment, and the pilot's diverted attention.
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
After departure, the pilot noticed that the tachometer for the left propeller was not operating. He decided to continue the flight when he found that he was able to keep the left and right propellers in synchronization at either full or cruise power. The pilot experienced the synchronization problem again when he reduced the power in preparation for landing. While on final approach, the pilot became preoccupied with the problem and impacted trees.
Factual narrative
On July 6, 1994, about 1140 central daylight time, a Beech Baron 58, N625P, was substantially damaged when it struck trees on approach to land at Kings Land O'Lakes Airport, Land O'Lakes, Wisconsin. The pilot received minor injuries. The 14 CFR Part 91 flight originated in Timmerman, Wisconsin, on an IFR flight plan which was cancelled prior to the initiation of the approach. The flight operated in visual meteorological conditions.
According to the pilot's statement, after departing Timmerman he realized that the tachometer for the left propeller was not operating. He found that he was able to keep the left and right propellers in synchronization at either full or cruise power, so he decided to continue the flight. As he began his approach to land at Kings Land O'Lakes Airport, he again experienced the synchronization problem when he reduced the power. While on final approach, he became preoccupied with the problem and impacted trees.
