What happened
The aircraft was engaged in a climbout phase following departure from the Drummond Island Airport (Y66) located on Drummond Island, Michigan. During this ascent, the airplane lost control or failed to maintain sufficient altitude, resulting in an impact with trees and the surrounding terrain.
The investigation
Post-accident examination of the wreckage revealed no evidence of pre-impact mechanical failures. Investigators found no anomalies with either the engine or the airframe that would have contributed to the accident. This suggests the aircraft was mechanically sound prior to the collision with the ground and vegetation.
Findings
Weather conditions at the time of the incident were monitored by an automatic weather surface observing system. Although this station was located approximately 35 nautical miles away at a bearing of 275 magnetic degrees from the airport, it reported relevant data at 1615. The wind was coming from 190 degrees, varying to 250 degrees, with a speed of 13 knots and gusts reaching 23 knots. These conditions indicate moderate turbulence or wind shear that may have affected climb performance.
Safety message
Pilots departing from airports in areas with complex terrain should remain vigilant regarding weather conditions and aircraft performance capabilities during the critical climbout phase, even when mechanical systems are functioning normally.
