NTSB summary
On November 18, 2001, about 1537 central standard time, a Robert N. Gilmore, Rans S-10, amateur built airplane, N96AU, registered to an individual, crashed following loss of engine power shortly after takeoff from Robbins Field, Oneonta, Alabama, while on a 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was destroyed and the private-rated pilot received fatal injuries. The flight was originating at the time of the accident. A witness stated that as the airplane climbed through about 250 feet after takeoff, when the airplane was about 2/3 of the way down runway 23, the propeller stopped rotating. The pilot initiated a slow turn to the left and dropped the nose. The airplane then fell sharply to the left and spiraled to the left one and a half turns and went out of sight behind trees. (See attached police department report.) Examination of the airplane at the crash site was performed by an FAA inspector. The airplane crashed about 100-150 yards northwest of runway 23, about 2/3 of the way down the runway. The airplane came to rest on a 050 degree heading, in a 45-degree nose down attitude. The engine was seized and the propeller had no rotational damage. The tachometer read 196.8 hours. (See attached record of telephone conversation.) Postcrash examination of the engine was performed by an FAA inspector and two mechanics who are knowledgeable of the engine model. The front cylinder walls showed evidence of galling, as did the compression ring, which remained compressed in the piston groove afte
Probable cause
The failure of the pilot to maintain airspeed following loss of engine power resulting in the airplane stalling and entering a spin from which it crashed. Factors in the accident was improper repair of the front cylinder intake manifold seal by the pilot after a prior accident which resulted in seizure of the front piston in the cylinder and failure of the engine and the pilots use of Alprazolam,
