On February 2, 2022, about 0656 eastern standard time, a Pilatus PC-12/47E, N357JK, was substantially damaged when it was involved in an accident at Long Island MacArthur Airport (ISP), Ronkonkoma, New York. The commercial pilot and a pilot-rated passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot stated that after the pilot-rated passenger joined him in completing the cockpit checklist, they prepared for engine start with the airplane’s parking brake applied. While pushing on the toe brakes he pushed the starter switch and verified that the oil pressure was rising, and the compressor turbine (Ng) had increased to 13%. At 13%, he noted the temperature of the engine oil, and moved the condition lever to flight idle per the checklist. He observed Ng increase to 40% and felt the airplane “lurching forward.” He pressed harder on the toe brakes, but the airplane continued forward, while the engine spooled-up. The airplane was fast approaching a parked, unoccupied Hawker 1000 airplane. The pilot reached to secure the Condition Lever, but his thumb slipped off the securing device. The Pilatus impacted and extensively damaged the Hawker. The right wing of the Pilatus separated during the impact sequence. The engine continued to operate, and the pilot-rated passenger stated that he assisted the pilot by moving the Condition Lever to the Cut-Off/Feather position, pulled the Fuel Shutoff and ACS Bleed control levers.

The airplane was equipped with a lightweight combination cockpit voice and flight data recorder, which was retained for download.
