# NTSB FTW96LA144: Beech V35A, N8323N, Clinton, LA, March 10, 1996 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: March 9, 1996, 23:55 local (Mar 10, 1996, 05:55 UTC) - Place: Clinton, LA - Coordinates: 30.860448, -91.009391 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=30.8604&lon=-91.0094&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 2 serious - Status: Completed, report July 17, 1996 - Report: Approved by Office Director - NTSB case key (mKey): 19781 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW96LA144 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/19781/pdf - Page: https://openairdocs.org/ntsb/FTW96LA144 ## Probable cause the pilot's improper positioning of the fuel selector which resulted in fuel starvation. Factors were the dark night light condition and the worn spark plugs. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, descent - normal - fluid,fuel - starvation (cause) - fuel tank selector position - improper, pilot in command (cause) - ignition system,spark plug - worn (contributing factor) - Forced landing, emergency landing - Hard landing, emergency landing - light condition - dark night (contributing factor) ## Analysis During the night cross-country flight, the engine lost power and a forced landing ensued. The airplane touched down with a 'heavy vertical impact.' Examination of the airplane revealed that the fuel tank selector was in the right tank position; however, the right wing tank was empty. The left tank contained approximately 9 gallons of fuel. The pilot reported that he was operating on the right tank when the power loss occurred, and that he switched to the left tank and attempted to restart the engine several times without success. All 12 of the spark plugs were found to have excessive plug gap, and testing of 2 of the plugs revealed that they would not fire over 40 PSI of pressure. Properly gapped spark plugs should fire steadily when tested up to pressures of 115 to 135 psi. ## Factual narrative On March 9, 1996, approximately 2355 central standard time, a Beech V35A, N8323N, was substantially damaged during a forced landing near Clinton, Louisiana. The commercial pilot and the passenger sustained serious injuries. The airplane was registered to and operated by a private owner. The Title 14 CFR Part 91 personal flight originated at 2210 in Jackson, Tennessee, and the intended destination was Baton Rouge, Louisiana. Dark night visual meteorological conditions prevailed and an instrument flight plan was filed. According to the pilot, the airplane was descending through 6,500 feet MSL, and the fuel selector was on the right tank, which was "indicating 1/4 tank," when the engine lost power. He switched to the left tank, which was "showing 1/3 tank," and attempted to restart the engine "several" times without success. A forced landing ensued to a "timbered field" and the airplane touched down with a "heavy vertical impact." Examination of the airplane by the FAA inspector revealed that the fuel tank selector was in the right tank position. During recovery of the airplane, when the wings were removed from the airplane, the right wing tank was found to be "dry of fuel" and approximately 9 gallons of fuel was drained from the left wing tank. On March 21, 1996, an engine tear down inspection was performed (report enclosed). All 12 of the Champion RHB32E spark plugs were found to have "excessive plug gap," and a test on 2 of the plugs performed with a spark plug testing machine revealed that the "plugs would not fire over 40 psi of pressure." According to the engine manufacturer, the recommended gap setting for these plugs is .016 to .018 inches and they should spark steadily when tested up to pressures of 115 to 135 psi. ## Aircraft - Registration: [N8323N](https://openairdocs.org/deregistered/N8323N-1996-11-29), registration cancelled 1996-11-29, S/N D8736 (OpenAirDocs) - Reported make and model: Beech V35A - Registry model: [Beech V35A](https://openairdocs.org/model/beech-v35a) (registry code 1151544) (OpenAirDocs) - Category: Airplane - Serial number: D-8736 - Engines: Continental IO-520-BB 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Linda C.

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.
