Narrative:
The Beechcraft struck a Blue Hill at 2280 feet during an ILS approach to Saranac Lake runway 23. The glide slope elevation at that point was approx. 2900 feet.

PROBABLE CAUSE: "Failure of the captain to establish a stabilized approach, his inadequate cross-check of instruments, his descent below specified minimum altitude at the final approach fix, and failure of the copilot to monitor the approach. Factors related to the accident were: weather conditions and possible precipitation static interference, caused by inadequate grounding between the radome and fuselage that could have resulted in unreliable glide slope indications."
