# NTSB LAX98LA054: Piper J3C-65, N91915, Stoil, CA, December 24, 1997 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: December 24, 1997, 11:50 local (19:50 UTC) - Place: Stoil, CA - Coordinates: 35.859188, -119.460968 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.8592&lon=-119.4610&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report January 28, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 30008 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX98LA054 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/30008/pdf - Page: https://openairdocs.org/ntsb/LAX98LA054 ## Probable cause The pilot's failure to maintain adequate obstacle clearance and his inadequate visual outlook.. Factors were a severed fuel line which resulted in an in-flight fire, which diminished the pilot's ability to land the airplane with smoke and fire in the cockpit. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, maneuvering - object - wire,transmission - visual lookout - inadequate, pilot in command (cause) - Fire, emergency descent/landing - fuel system,line fitting - cut/severed (contributing factor) - fluid,fuel - fire - Gear collapsed, landing - flare/touchdown - fuselage,crew compartment - fire (contributing factor) - aircraft control - diminished, pilot in command (contributing factor) - flare - misjudged, pilot in command - landing gear,main gear - overload ## Analysis The pilot desired to become an agricultural pilot and was practicing low passes over a field. The pilot failed to see three power transmission cables and the airplane struck a 300-foot-span of number 8 gauge copper conductor suspended about 45 to 50 feet above the ground with its propeller. An in-flight fire erupted in the cockpit area. The fire was located at a break in a fuel line from the fuel selector valve to the engine. The pilot suffered second and third degree burns to his face, arms, and left leg and landed the airplane hard, collapsing one of the main landing gear. He egressed the airplane unaided while the fire spread destroying the airplane. There was no evidence of mechanical failures or malfunctions with the airplane before the collision with power transmission cables. ## Factual narrative On December 24, 1997, at 1150 hours Pacific standard time, a Piper J3C-65, N91915, collided with wires and landed in an open field near Stoil, California. The airplane was destroyed by postimpact fire. The certificated commercial pilot, and sole occupant, received serious injuries. The airplane was being operated by the pilot as a personal flight when the accident occurred. The local area flight originated from a private farm airstrip near Tulare, California, at 1045. Visual meteorological conditions prevailed. According to the Federal Aviation Administration (FAA), the pilot recently received his commercial pilot certificate on October 26, 1997. The pilot indicated he desired to become an agricultural pilot and was practicing low passes over a field. The airplane struck a 300-foot-span of number 8 gauge copper conductor suspended about 45 to 50 feet above the ground with its propeller. The pilot told an FAA inspector an in-flight fire erupted in the cockpit area after the collision with the power transmission cable. The fire was located at a break in a fuel line from the fuel selector valve to the engine. The pilot landed the airplane, collapsing one of the main landing gear. He egressed the airplane unaided. The fire spread destroying the airplane. The pilot suffered second and third degree burns to his face, arms, and left leg. The pilot stated in his accident report that he failed to see the power transmission cables before the collision. The pilot also indicated there were no mechanical failures or malfunctions with the airplane. ## Aircraft - Registration: [N91915](https://openairdocs.org/deregistered/N91915-1998-09-01), registration cancelled 1998-09-01, S/N 16330 (OpenAirDocs) - Reported make and model: Piper J3C-65 - Registry model: [Piper J3C-65](https://openairdocs.org/model/piper-j3c-65) (registry code 7100510) (OpenAirDocs) - Category: Airplane - Serial number: 16330 - Airframe hours: 4790 - Engines: Continental C85 85 horsepower reciprocating - Damage: Destroyed - Fire: In-Flight - Flight: Personal, Part 91 - Registered owner: Cottle, William L - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 6, 1997, 168 hours before - Departed: TULARE, CA ## Flight crew As NTSB recorded them.

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.
