AOPA ASI Issues Early Analysis of PC-12 Crash in Wyoming
Turboprop single experienced altitude oscillations just before crash

AOPA’s Air Safety Institute (ASI) today released an Early Analysis video that provides an initial examination of the Pilatus PC-12 crash north of Gillette, Wyoming, that occurred last Friday. The instrument-rated private pilot and six passengers aboard the turboprop single perished in the accident.

Registered as N357HE to Haynie Enterprises, the PC-12 was two hours into a flight from Nebraska City Municipal Airport (KAFK), where a fuel stop was made, to Montana’s Billings Logan International Airport (KBIL) when it crashed. FlightAware flight data indicates that the aircraft was at FL260 when it began to experience altitude oscillations about three minutes before the crash. N357HE’s ADS-B transmissions ceased at 23,400 feet.
