The loss of engine power for unknown reasons was a contributing factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - normal - reason for occurrence undetermined (contributing factor) - Forced landing, emergency descent/landing - In flight collision with terrain/water, emergency descent/landing - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command (cause) ## Analysis The airplane sustained substantial damaged during a forced landing following a total loss of engine power. The pilot stated that 1.5 hours into his flight the engine, "...developed a slight miss." Five minutes later the engine suffered a total loss of engine power. The pilot executed a forced landing but the airplane landed short of the intended landing area. The airplane sustained damage due to impact with trees and what the pilot stated as a, "...rough off airport landing." No anomalies were found with respect to the airframe, engine, or systems that could be identified as existing prior to impact. ## Factual narrative On April 16, 2002, about 1400 central daylight time, an amateur-built Long FEW TF-51, N51HL, piloted by a private pilot, sustained substantial damage during a forced landing after a loss of engine power while in cruise flight near Summersville, Missouri. The 14 CFR Part 91 personal flight was not on a flight plan and was operating in visual meteorological conditions. The pilot, who was the sole occupant, received minor injuries. The flight originated from the Rogers Municipal-Carter Field Airport about 1200. The intended destination of the flight was the Mount Vernon Airport, Mount Vernon, Illinois. The pilot stated that 1.5 hours into his flight the engine, "...developed a slight miss." The pilot started a diversion to the Mountain View Airport, Mountain View, Missouri, the nearest airport to his location. Five minutes later the engine suffered a total loss of engine power. The pilot selected a landing zone for the forced landing but the airplane landed short of the intended landing area. The airplane sustained damage due to impact with trees and what the pilot stated as a, "...rough off airport landing." The Federal Aviation Administration conducted a postaccident examination of the airplane. No anomalies were found with respect to the airframe, engine, or systems that could be identified as existing prior to impact. ## Aircraft - Registration: [N51HL](https://openairdocs.org/deregistered/N51HL-2003-03-12), registration cancelled 2003-03-12, S/N 23, built 1999 (OpenAirDocs) - Reported make and model: Long FEW TF-51 - Registry model: [Long Earl H FEW TF-51](https://openairdocs.org/model/long-earl-h-few-tf-51) (registry code 05604EJ) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 23 - Engines: General Motors HO-350 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Earl H.

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.
