NTSB narrative
A witness at a nearby maintenance facility stated the pilot telephoned him and told him that, during engine start, one engine sputtered and abruptly stopped. The witness stated the pilot told him he wanted to fly the airplane over to have the problem looked at. A witness, who was an airline transport-rated corporate pilot, observed the airplane on takeoff roll and stated the airplane rotated "really late," using approximately 4,000 feet of runway. He stated the airplane climbed to about 400 or 500 feet, then descended in a left spin into the trees. The airplane collided with the ground and caught fire. Examination of the right engine revealed external fire damage and no evidence of mechanical malfunction. Examination of the left engine revealed external fire damage. Disassembly examination of the left engine revealed the rear side of the No. 5 piston from top to bottom was eroded away with characteristics consistent with detonation. The spark plugs displayed "normal" deposits and wear, except the No. 5 bottom plug was contaminated with a fragment of piston ring material, the No. 5 top plug had a dark sooty appearance, and the nose core of the No. 2 bottom plug was fragmented. Flow bench examination of the left fuel servo revealed no abnormalities. The fuel flow manifold diaphragm was heat-damaged. Flow bench examination of the fuel injector lines and nozzles on a serviceable fuel flow manifold revealed the lines and nozzles were free of obstruction. A review of Emergency Operating Procedures for the Aerostar 601P revealed the following: "Normal procedures do not require operation below the single engine minimum control speed, however, should this condition inadvertently arise and engine failure occur, power on the operating engine should immediately be reduced and the nose lowered to attain a speed above ... the single engine minimum control speed."
Probable cause
The pilot's failure to maintain airspeed during emergency descent, which resulted in an inadvertent stall/spin and uncontrolled descent into trees and terrain. A factor was the loss of engine power in one engine due to pre-ignition/detonation.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
