KOKOMO, Ind. — A newly-released report suggests the crash that killed a well-known Tampa plastic surgeon may have been caused by the wrong type of fuel.
Dr. Daniel P. Greenwald, 59, died when his Piper Aerostar 602P went down on Oct. 5 outside of Kokomo, Indiana. The plane had left the Kokomo Municipal Airport and hit a field around 3.6 miles south.
The National Transportation Safety Board says an examination has revealed a liquid consistent with Jet A in a fuselage tank and in the fuel lines leading to both engines. Several of the engine spark plugs exhibited damage consistent with detonation.
Investigators say the wreckage path was consistent with an "accelerated stall."
Greenwald was a registered pilot, and there were no visual meteorological conditions that would have impacted the flight, investigators say. He had been providing customer training in the area.
The NTSB report says the airport employee who fueled the airplane asked Greenwald if he wanted jet fuel, and the pilot said "yes." He said he asked because the airplane looked like a jet airplane.
When the airplane arrived, investigators say the employee pulled the Jet A fuel truck out and parked it in front of the airplane while the pilot was still inside. The employee said he asked Greenwald again if he was wanted jet fuel, and the pilot said "yes."
The employee fueled the airplane with about 163 gallons of Jet A from the fuel truck.
According to the report, witnesses said the engine sounded normal before takeoff.
