# NTSB BFO94LA048: Jenks Skybolt, N14DJ, Brockport, NY, February 19, 1994 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: February 19, 1994, 13:30 local (18:30 UTC) - Place: Brockport, NY - Coordinates: 43.280353, -77.789451 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=43.2804&lon=-77.7895&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report January 26, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 8897 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=BFO94LA048 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/8897/pdf - Page: https://openairdocs.org/ntsb/BFO94LA048 ## Probable cause A loss of engine power due to undetermined reason (s). A factor in this accident was the snow covered, rough/uneven terrain which caused the airplane to nose over during landing roll. ## 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 (cause) - Forced landing, descent - emergency - Nose over, landing - roll - terrain condition - snow covered (contributing factor) - terrain condition - rough/uneven (contributing factor) ## Analysis The pilot said he was flying his airplane to a local area to practice aerial maneuvers. He reported that the engine began to run intermittently. As he continued his flight, the condition worsened and he attempted to return to his departure airfield under a partial power condition. He said that he had to secure the engine and execute a forced landing to a snow covered field. During the landing roll in the snow covered rough terrain, the airplane nosed over. A post-accident examination of the engine did not disclose a reason for the partial power condition. ## Factual narrative On February 19, 1994 about 1330 hours eastern standard time an experimental Jenks Skybolt, N14DJ, nosed over during landing roll at the termination of a power-off forced landing near Brockport, New York. The forced landing was precipitated by a loss of engine power. The certificated private pilot, the sole occupant, was not injured and the airplane sustained substantial damage. The local area flight was being operated by the pilot/owner. The flight originated in Brockport about 1320 hours. Visual meteorological conditions prevailed and a flight plan was not filed. The pilot was telephonically interviewed by a Safety Board investigator after the accident. Additionally, the pilot provided a written statement to the Board. The pilot said he was flying his airplane to a local area to practice aerial maneuvers. He said the engine began to run intermittently. As he continued his flight, the condition worsened and he attempted to return to his departure airfield under partial power. He said that he had to secure the engine and execute a forced landing to a snow covered field. During the landing roll in the snow covered rough terrain, the airplane nosed over. An FAA safety inspector examined the airplane after the accident. He reported the "Aircraft lost power due to pressure carburetor problem. Carb to be checked for problem but due to age of carb parts unavailable." An examination of the engine and its components did not reveal the cause of the loss of power. ## Aircraft - Registration: N14DJ (not matched to a registry record) - Reported make and model: JENKS SKYBOLT - Category: Airplane, amateur-built - Serial number: 1078 - Airframe hours: 426 - Engines: LYCOMING IO-540 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: James W.

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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
