What happened
Prior to departing from Holland, Michigan, the pilot received a pre-flight briefing that highlighted flight precautions for instrument flight rules (IFR) conditions across the entire planned route. The briefing specifically noted the possibility of occasional light to moderate rime and/or mixed icing within clouds below 18,000 feet. Despite these warnings, the pilot elected to proceed with the departure.
At 1132 Eastern Standard Time, the pilot contacted Buffalo Flight Watch to request current weather information for Syracuse. The controller advised that flight precautions remained in effect due to occasional rime icing conditions between altitudes of 2,000 and 9,000 feet. Witnesses on the ground observed the aircraft making a left turn to establish final approach. Shortly thereafter, the aircraft descended rapidly and impacted the rocky shore of Lake Skaneateles, located approximately 0.5 nautical miles east of the airport.
The investigation
Post-accident examination of the wreckage revealed no evidence of preimpact mechanical malfunctions or failures that would have contributed to the accident. A critical factor identified during the investigation was that the aircraft did not possess wing deicing capability, which limited its ability to safely operate in the reported icing conditions.
Findings
The lack of adequate anti-icing equipment for the specific weather conditions encountered, combined with the decision to continue the flight despite known icing hazards, were significant factors. The rapid descent and subsequent impact with the lake shore occurred under conditions where ice accumulation likely degraded aerodynamic performance.
