# NTSB FTW95LA392: Grumman G-164B, N211JM, Springlake, TX, June 8, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 7, 1995, 20:00 local (Jun 8, 1995, 01:00 UTC) - Place: Springlake, TX - Coordinates: 34.229171, -102.299606 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=34.2292&lon=-102.2996&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report October 27, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 19582 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW95LA392 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/19582/pdf - Page: https://openairdocs.org/ntsb/FTW95LA392 ## Probable cause THE LOSS OF ENGINE POWER DUE TO THE UNCONTAINED FAILURE OF THE THIRD STAGE TURBINE WHEEL. A FACTOR WAS THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING. ## 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, go-around (vfr) - turbine assembly,turbine wheel - failure,total (cause) - powerplant - fire - emergency procedure - initiated, pilot in command - Forced landing, emergency descent/landing - In flight collision with terrain/water, emergency landing - terrain condition - ditch - terrain condition - none suitable (contributing factor) ## Analysis THE PILOT OF A TURBINE ENGINE POWERED AERIAL APPLICATION AIRPLANE EXPERIENCED AN UNCONTAINED ENGINE FAILURE AND FIRE WHEN HE ADDED POWER TO EXECUTE A GO AROUND AT HIS HOME BASE AIRPORT. THE PILOT PULLED THE ENGINE EMERGENCY FUEL SHUTOFF, SUCCESSFULLY EXTINGUISHING THE ENGINE FIRE. THE PILOT ELECTED TO EXECUTE A FORCED LANDING TO A CORN FIELD BEYOND A ROAD AT THE DEPARTURE END OF THE RUNWAY. THE TAILWHEEL IMPACTED A DRAINAGE DITCH ON THE SHOULDER OF THE ROAD AND THE AIRPLANE NOSED OVER COMING TO REST IN THE INVERTED POSITION. POST EXAMINATION OF THE ENGINE REVEALED THAT THE LOSS OF ENGINE POWER WAS ATTRIBUTED TO THE FAILURE OF THE THIRD STAGE TURBINE WHEEL ASSEMBLY. ## Factual narrative On June 7, 1995, approximately 2000 central daylight time, a Grumman G-164B, N211JM, was substantially damaged during a forced landing near Springlake, Texas. The airline transport rated pilot was not injured. The airplane was being operated by Sanderson Grain Inc., under Title 14 CFR Part 137. Visual meteorological conditions prevailed for the aerial application flight for which no flight plan was filed. According to the pilot, the engine lost power when he added power to execute a go around when overflying the runway at his home based airport. The pilot stated that the "engine failed then a big stream of fire followed coming out of the exhaust pipe." The pilot added that he pulled the engine emergency fuel shutoff, and the fire was extinguished. In the enclosed pilot/operator report, the pilot states that he elected to continue straight ahead and attempt a forced landing in a corn field beyond the county road at the departure end of the runway. The pilot added that the tailwheel impacted a drainage ditch between the road and the corn field, and the airplane nosed over coming to rest in the inverted position. The airplane sustained structural damage to a wing spar and the tail wheel attaching point. Post examination of the engine by the owners representative revealed that the loss of engine power, and subsequent fire, was attributed to the uncontained failure of the third stage turbine wheel assembly. ## Aircraft - Registration: [N211JM](https://openairdocs.org/aircraft/N211JM), registered now, S/N 69B, built 1976 (OpenAirDocs) - Reported make and model: GRUMMAN G-164B - Registry model: [Grumman Acft ENG Cor-Schweizer G-164B](https://openairdocs.org/model/grumman-acft-eng-cor-schweizer-g-164b) (registry code 3952802) (OpenAirDocs) - Registry engine: [Pratt & Whitney R-985 series](https://openairdocs.org/engine/pratt-whitney-r-985-series) (registry code 52008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 698 - Airframe hours: 6785 - Engines: GARRETT TPE331-1 665 horsepower turbo prop - Damage: Substantial damage - Fire: In-Flight - Flight: Aerial application, Part 137 - Registered owner: James B.

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.
