# NTSB CHI95LA112: Globe GC-1B, N78103, Norton, KS, March 13, 1995 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: March 13, 1995, 17:30 local (23:30 UTC) - Place: Norton, KS - Coordinates: 39.830833, -99.890693 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.8308&lon=-99.8907&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor, 1 uninjured - Status: Completed, report October 13, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 9861 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI95LA112 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9861/pdf - Page: https://openairdocs.org/ntsb/CHI95LA112 ## Probable cause the reason for the loss of engine power was undetermined. The rough, uneven terrain encountered during the forced landing was a factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - In flight collision with terrain/water, emergency landing - terrain condition - rough/uneven (contributing factor) - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command (contributing factor) ## Analysis THE PILOT, ALONG WITH A PILOT RATED PASSENGER (HIS MECHANIC), INITIATED A FLIGHT AFTER MAINTENANCE ON THE AIRPLANE. DURING THE FLIGHT THE OIL PRESSURE WAS OBSERVED TO READ ZERO. WHILE ATTEMPTING TO RETURN TO THE AIRPORT, THE ENGINE BEGAN TO RUN ROUGH. THE PILOT THEN MADE A FORCED LANDING ON A TERRACED WHEAT FIELD AND THE AIRPLANE SUSTAINED DAMAGE IN THE UNEVEN TERRAIN. AN EXAMINATION OF THE AIRFRAME AND ENGINE FAILED TO REVEAL THE REASON FOR THE POWER LOSS AND NO ANOMALIES WERE FOUND IN ANY OF THE SYSTEMS EXAMINED. ## Factual narrative On March 13, 1995, at 1730 central standard time, a Globe GC-1B, N78103, piloted by a private pilot, lost power and made a forced landing near Norton, Kansas. The airplane sustained substantial damage during the off airport landing. The pilot reported minor injuries, while his one passenger reported no injuries. The personal 14 CFR Part 91 flight was operating in visual meteorological conditions. No flight plan was on file. The flight originated at Norton, Kansas, at 1715. This flight was the first flight after maintenance on the engine. The pilot stated that during the flight the oil pressure went to zero and while he was attempting to return to the airport the engine began to run rough, and he then initiated a forced landing. An examination of the engine after the accident failed to reveal any mechanical anomalies. The examination verified that fuel was available, with approximately 16 gallons found. The spark plugs were in satisfactory condition, that there was continuity through the engine, and that all the cylinders had compression. The number one cylinder was removed and no anomalies were found. The oil pressure gage and sending units were checked and found to operate. ## Aircraft - Registration: [N78103](https://openairdocs.org/aircraft/N78103), registered now, S/N 2103, built 1946 (OpenAirDocs) - Reported make and model: GLOBE GC-1B - Registry model: [Globe GC-1B](https://openairdocs.org/model/globe-gc-1b) (registry code 9230104) (OpenAirDocs) - Registry engine: [Continental C125 series](https://openairdocs.org/engine/continental-c125-series) (registry code 17011, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 2103 - Airframe hours: 1215 - Engines: LYCOMING IO-360-A1B6 200 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Nelson, Larry W. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, December 22, 1994, 9 hours before - Departed: NRN ## Flight crew As NTSB recorded them.

Test flight after engine work. Lost oil pressure. Landed off airport. No engine anomalies found. Report unverified. 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.
