NTSB summary
HISTORY OF FLIGHT On August 30, 1996, at 1230 eastern daylight time (edt), a Mankovich Revenge, N7037J, operated by an airline transport pilot, was destroyed when during descent for landing, the airplane departed controlled flight. The airplane subsequently impacted in a corn field 4 miles northeast of Jeffersonville, Indiana. Visual meteorological conditions prevailed at the time of the accident. The business flight was part of a ferry formation to an airshow performance with three other Formula V class airplanes being conducted under 14 CFR Part 91. No flight plan was on file. The pilot sustained fatal injuries. The flight originated at Seymour, Indiana, at 1210 edt. According to officials in the Formula V Air Racing Association, two days of practice and race familiarization flights for new Formula V air racing pilots were held at Freeman Municipal Airport, Seymour, Indiana, beginning on August 28, 1996. At the practice sessions, the pilot, a new Formula V air racing pilot, was to demonstrate competency in the maneuvers required by the Formula V Air Racing Association to compete in air races. According to one witness who spoke to the pilot several times on August 28, 1996, the pilot said that he experienced smoke in the cockpit and had to cut short a qualifying flight where he was required to demonstrate 180-degree rolls to inverted flight, both to the left and right. He did not accomplish the maneuvers. The pilot told the witness that there was a small hole in the firewall and with the help of some of the other air race pilots, he changed a hose. He also told the witness
Probable cause
inadequate maintenance and inspection of the airplane by the pilot/owner and other airframe and powerplant mechanics, which failed to assure adequate sealing of the engine firewall, and led to the pilot's incapacitation due to carbon monoxide.
