# NTSB FTW95LA360: Boeing A75N1, N68722, Evadale, TX, August 24, 1995 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: August 24, 1995, 12:15 local (17:15 UTC) - Place: Evadale, TX - Coordinates: 30.32913, -94.060508 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=30.3291&lon=-94.0605&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report January 29, 1996 - Report: Approved by Office Director - NTSB case key (mKey): 19553 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW95LA360 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/19553/pdf - Page: https://openairdocs.org/ntsb/FTW95LA360 ## Probable cause A FAILURE THAT RESULTED IN SEPARATION OF THE #5 CYLINDER AND LOSS OF ENGINE OIL. THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING WAS A RELATED FACTOR. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - mech failure/malf, cruise - engine assembly,cylinder - failure,total (cause) - engine assembly,cylinder - separation (cause) - fluid,oil - loss,total (cause) - Forced landing, emergency descent/landing - In flight collision with object, emergency landing - terrain condition - none suitable (contributing factor) - object - tree(s) ## Analysis IN CRUISE FLIGHT, THE PILOT NOTICED OIL ON THE FLYING WIRES AND HEADED FOR THE NEAREST AIRPORT. THE ENGINE LOST POWER SEVERAL MINUTES LATER, AND THE PILOT ATTEMPTED TO LAND IN THE 'ONLY AVAILABLE' LOCATION, A FIELD SURROUNDED BY TREES. THE AIRPLANE STRUCK THE TREES DURING APPROACH TO THE FIELD. EXAMINATION OF THE ENGINE REVEALED THE #5 CYLINDER HAD SEPARATED IN FLIGHT, RESULTING IN THE LOSS OF OIL. ## Factual narrative On August 24, 1995, at 1215 central daylight time, a Boeing A75N1, N68722, was substantially damaged when it struck trees during a forced landing near Evadale, Texas. The commercial pilot/operator received minor injuries. No flight plan was filed and visual meteorological conditions prevailed for the Title 14 CFR Part 91 personal flight. The airplane departed Jennings, Louisiana, at 1130 en route to Brenham, Texas. According to the pilot, the flight of two airplanes was cruising at 2,500 feet MSL when he "noted oil on the flying wires" of his airplane. The pilot of the second airplane observed an "oil leak about one foot in width extending from the engine to the cockpit" of the accident airplane. Both airplanes reversed course and headed towards the nearest airport. "Several minutes later" the accident airplane's engine lost power. The pilot reported that the "only available landing spot" was "a small field surrounded by trees." During approach to the field, the airplane struck trees. The wings and center section were "destroyed" and the emmpenage was "bent." Examination of the engine by a certificated mechanic revealed that the #5 cylinder had separated in flight. The cylinder was not recovered which prevented determination of the reason for its separation. In the opinion of the mechanic, "the cylinder coming off the engine was the ultimate cause of failure (oil and manifold pressure loss.)" ## Aircraft - Registration: [N68722](https://openairdocs.org/aircraft/N68722), registered now, S/N 75-3603, built 1942 (OpenAirDocs) - Reported make and model: BOEING A75N1 - Registry model: [Boeing A75N1(PT17)](https://openairdocs.org/model/boeing-a75n1-pt17) (registry code 1380134) (OpenAirDocs) - Registry engine: [Lycoming R680](https://openairdocs.org/engine/lycoming-r680) (registry code 41540, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 75-3603 - Airframe hours: 2863 - Engines: LYCOMING R-680-B4D 225 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: John S.

At cruise oil on wing wires. Turned to airport. Engine quit. Struck trees landing. NR5 cylinder had separated. From the NTSB's public API. 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.
