Factors relating to this accident were the rough, uneven runway, and the trees. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - On ground/water encounter with terrain/water, takeoff - roll/run - airport facilities,runway/landing area condition - rough/uneven (contributing factor) - Loss of control - in flight, takeoff - initial climb - directional control - restricted (cause) - landing gear,nose gear - jammed - In flight collision with object, takeoff - initial climb - object - tree(s) (contributing factor) - In flight collision with terrain/water, descent - uncontrolled ## Analysis The pilot said that during takeoff from a private airstrip, the airplane 'hit 3 bumps in the runway causing the nose gear to jam to the right, holding it in [an] unrecoverable slip condition [and], not allowing the aircraft to climb or turn left.' The pilot said that the left wing hit trees causing the airplane to flip over on to its back. Examination of the wreckage showed the airplane's nose wheel deflected and stuck to the right. Examination of the remaining airplane systems revealed no anomalies. ## Factual narrative On June 8, 2000, at 2100 eastern daylight time, an Edgerly Rans S-12, homebuilt airplane, N3148E, operated by a student pilot, sustained substantial damage when on takeoff from a grass airstrip near Hartford, Michigan, the airplane entered an uncommanded right turn, struck a tree and subsequently impacted the ground. Visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under 14 CFR Part 91. No flight plan was on file. The student pilot reported no injuries. The local flight was originating at the time of the accident. In his written statement, the pilot said that during takeoff from a private airstrip, the airplane "hit 3 bumps in the runway causing the nose gear to jam to the right, holding it in [an] unrecoverable slip condition [and], not allowing the aircraft to climb or turn left." The pilot said that the left wing hit trees, causing the airplane to flip over on to its back. A Federal Aviation Administration inspector examined the airplane at the accident location. The airplane was found resting on its back. Its left wing was broken aft. The airplane's nose wheel was deflected and stuck in a right turn. Examination of the airplane's engine, engine controls, and other airplane systems revealed no anomalies. ## Aircraft - Registration: [N3148E](https://openairdocs.org/deregistered/N3148E-2013-08-14), registration cancelled 2013-08-14, S/N 05960726, built 1997 (OpenAirDocs) - Reported make and model: EDGERLY S-12 - Registry model: [Edgerly James A S-12](https://openairdocs.org/model/edgerly-james-a-s-12) (registry code 05605K0) (OpenAirDocs) - Registry engine: [Bombardier ROTAX (ALL)](https://openairdocs.org/engine/bombardier-rotax-all) (registry code 09050, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 05960726 - Airframe hours: 186 - Engines: Rotax 503-DLD1 52 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: James A.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
