The pilot tried to get airborne again; however, the airplane touched down hard, bounced, and traveled off the end of the runway into a mangrove swamp. Examination of the airplane by a Federal Aviation Administration inspector revealed that no flight control anomalies were found. During a post-accident examination, fuel was supplied to the engine and the engine was started. The engine ran at 1700 rpm with no anomalies noted. However, it could not be run any higher than 1700 rpm due to a bent propeller shaft that was damaged during the accident impact. ## Factual narrative On January 25, 2009, at about 1450 eastern standard time, an Aero Commander 112A, N1006J collided with a mangrove swamp at the end of the runway, during takeoff from the Everglades Airpark, Everglades City, Florida. The certificated private pilot and the passenger received minor injuries and the airplane was substantially damaged. The airplane was operated as a personal flight under the provisions of 14 Code of Federal Regulations (CFR) Part 91. No flight plan was filed. Visual meteorological conditions prevailed for the flight to North Perry Airport, Hollywood, Florida. The pilot stated that after run-up, he taxied to the departure end of runway 33. All engine indications were normal when he began the takeoff roll. He said that about halfway down the runway, the airplane lifted off and climbed out at 75 knots. Approximately 15 feet above the ground, the engine lost partial power, and the airplane descended to the runway. The pilot said he tried to get airborne again; however, the airplane touched down hard, bounced, and traveled off the end of the runway into a mangrove swamp. Examination of the airplane by a Federal Aviation Administration inspector revealed that no flight control anomalies were found. A cursory examination of the engine revealed that it had minimal external damage and was able to be run. The fuel was examined prior to the engine run and no contaminates were noted in the fuel. The propeller shaft was bent, and the damaged propeller blades were cut to facilitate the engine run. Fuel was supplied to the engine and the engine was started. The engine ran up to 1700 rpm with no anomalies noted. However, it could not be run any higher due to the violent shaking of the bent propeller shaft. ## Aircraft - Registration: [N1006J](https://openairdocs.org/deregistered/N1006J-2016-08-05), registration cancelled 2016-08-05, S/N 126, built 1973 (OpenAirDocs) - Reported make and model: AERO COMMANDER 112A - Registry model: [Aero Commander 112](https://openairdocs.org/model/aero-commander-112) (registry code 0144701) (OpenAirDocs) - Registry engine: [Lycoming I0360 series](https://openairdocs.org/engine/lycoming-i0360-series) (registry code 41515, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 126 - Airframe hours: 2901 - Engines: Lycoming IO-360-D6 200 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Last inspection: Annual, May 19, 2008, 23 hours before - Departed: X01, Everglades City, FL - Destination: HWO, Hollywood, FL - Airport: X01, Everglades Airpark, runway 15, 2,400 × 50 ft, asphalt ## Flight crew As NTSB recorded them.
