The inadequate condition inspection by the mechanic, the cracked fuel line, the trees, and the pilot's lack of experience in the airplane type were contributing factors. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, approach - fuel system,line - cracked (contributing factor) - maintenance,replacement - disregarded, pilot in command (cause) - operation with known deficiencies in equipment - performed, pilot in command (cause) - maintenance,inspection - inadequate, other maintenance personnel (contributing factor) - In flight collision with terrain/water, descent - emergency - object - tree(s) (contributing factor) - planned approach - inadequate, pilot in command (cause) - lack of total experience in type of aircraft, pilot in command (contributing factor) ## Analysis The airplane was substantially damaged following a total non-mechanical loss of engine power during a climbout in an experimental amateur built airplane which had not flown for approximately two years. It was the pilot's first flight in the accident airplane. The pilot planned to fly three low approaches to familiarize himself with the airplane. The engine quit during climbout following the second planned approach at the destination airport. The pilot then executed a turn back to the airport and stalled the airplane over a wooded area. The airplane's parachute recovery system was deployed, and the airplane descended into the wooded area. Prior to the flight, the pilot was told by the mechanic, who signed off a condition inspection on the airplane, to replace the fuel lines on the airplane, but the pilot stated he would change the fuel lines when he arrived at the destination airport. Examination of the fuel line revealed a crack in the line between the fuel tanks and the fuel sump. ## Factual narrative On May 20, 2002, at 1850 eastern daylight time, a Wattier Tornado, N5143C, piloted by a private pilot, sustained substantial damage on impact with trees following a total loss of engine power during climbout from runway 09 (2,517 feet by 120 feet, turf) at the Grant Airport (01C), Grant, Michigan. Visual meteorological conditions prevailed at the time of the accident. The 14 CFR Part 91 personal flight was not operating on a flight plan. The pilot reported no injuries. The flight originated from the Wilderness Airpark Airport (24M), Kent City, Michigan, at 1830, en route to 01C. The airplane had not flown for approximately 2 years prior to accident flight. It was the pilot's first flight in the airplane. A mechanic, who completed a condition inspection of the airplane prior to the flight, told the pilot that the fuel lines "seemed to be getting hard" and needed to be replaced "right-away." The pilot told him that he was going to replace the fuel lines when he arrived at 01C. The airplane did not have an airworthiness certificate on board, and the pilot did not obtain a ferry permit to 01C. The pilot reported that he departed 24M after a "...condition inspection [and] multiple high speed taxis (tried to insure engine operations and sufficient runway length for takeoff)." The airplane climbed to 2,500 feet and flew eight miles north to 01C. The pilot added, "my plan was to fly 3 low approaches at Grant before actually trying to touch down. (To gain familiarity with plane, airport and current conditions). Engine stopped after 2nd low approach. (during climb back to pattern altitude.) Tried to glide past trees. Stalled the plane." Upon failure of the engine, the pilot attempted a turn back to the runway. The airplane's parachute recovery system was then deployed, and the airplane descended into trees under a parachute, which resulted in structural damage to both wings. The Federal Aviation Administration inspector's examination of the fuel system revealed a crack in the fuel line leading from the fuel tanks to the fuel sump. ## Aircraft - Registration: [N5143C](https://openairdocs.org/deregistered/N5143C-2022-12-24), registration cancelled 2022-12-24, S/N 09258250HK0036, built 1995 (OpenAirDocs) - Reported make and model: Wattier Tornado - Registry model: [Wattier Lawrence D TORNADO](https://openairdocs.org/model/wattier-lawrence-d-tornado) (registry code 05620VC) (OpenAirDocs) - Registry engine: [Bombardier ROTAX (ALL)](https://openairdocs.org/engine/bombardier-rotax-all) (registry code 09050, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 9258250HK0036 - Airframe hours: 210 - Engines: Rotax 582 65 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Kris J.

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.
