The pilot reported a loss of engine power. The pilot landed back on the runway, but only had about 200 feet of runway remaining. The airplane departed the end of the runway, down a steep embankment, the landing gear then dug into soft ground, and came to rest upside down. An engine examination revealed that the number 2 cylinder had cracked at the forward spark plug opening, all around the circumference of the cylinder and at the intake valve. The crack was opened about 1/8 of an inch. The remainder of the engine and accessories did not display any discrepancies. Fuel was observed and no contamination was found. ## Factual narrative On March 13, 2001, about 1330 central standard time, a Grumman G-164A, N5076, registered to a private owner, operating as a Title 14 CFR Part 137 aerial application flight, lost power on takeoff and nosed over at the Popularville-Pearl River County Airport, Popularville, Mississippi.
