A factor was the lack of suitable terrain for the forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, takeoff - initial climb - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - On ground/water encounter with terrain/water, emergency landing - terrain condition - none suitable (contributing factor) - terrain condition - rough/uneven ## Analysis During intitial takeoff climb, at an altitude of 100 - 150 feet agl, the engine lost partial power. The pilot intitiated a gradual turn as he prepared to make a forced landing. The airplane impacted rough/uneven terrain, coming to rest in an area of thick brush. The reason for the partial loss of engine power was not determined. ## Factual narrative On August 31, 2001, at 1415 central daylight time, a Piper PA-28 airplane, N525Z, registered to and operated by the pilot, was substantially damaged during a forced landing following a partial loss of power after takeoff from runway 35 at the Harvey Young Municipal Airport, Tulsa, Oklahoma. The commercial pilot and his passenger were not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The local flight was originating at the time of the accident. On the NTSB Pilot/Operator Aircraft Accident Report, the pilot reported that shortly after takeoff at an altitude estimated to be between 100 to 150 feet agl, the engine lost power but continued to run. A gradual turn was initiated as he prepared for a forced landing. "Enough power was being developed to turn the airplane and get it over airport property." The airplane impacted rough sloping terrain, where the left main gear broke off, and skidded into a thick brush area. The reason for the partial loss of engine power was not determined. ## Aircraft - Registration: [N525Z](https://openairdocs.org/deregistered/N525Z-2002-01-10), registration cancelled 2002-01-10, S/N 28-301, built 1961 (OpenAirDocs) - Reported make and model: Piper PA-28 - Registry model: [Piper PA-28](https://openairdocs.org/model/piper-pa-28) (registry code 7102801) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 301 - Airframe hours: 2876 - Engines: Lycoming O-320 B2B 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Donald J.
