# NTSB MIA00LA162: Cessna A150M, N9834J, Gainesville, GA, May 18, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 18, 2000, 16:20 local (20:20 UTC) - Place: Gainesville, GA - Coordinates: 34.289501, -83.829414 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=34.2895&lon=-83.8294&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report March 2, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49229 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA00LA162 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49229/pdf - Page: https://openairdocs.org/ntsb/MIA00LA162 ## Probable cause The pilot's failure to use proper soft field landing technique while attempting a forced landing to an open field following a loss of engine power which resulted in a hard landing. Factors in the accident were weather conditions conducive to formation of carburetor icing, and the uphill slope of the field chosen 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) - nonmechanical, cruise - weather condition - carburetor icing conditions (contributing factor) - Forced landing, emergency descent/landing - terrain condition - open field - terrain condition - uphill (contributing factor) - Hard landing, landing - flare/touchdown - soft field landing/procedure - improper, pilot in command (cause) ## Analysis According to statements by the pilot and the passenger, at about 3,500 feet msl, while sightseeing in the Lake Lanier area, the engine lost power, and attempts to identify and correct the problem were unsuccessful. The field selected for the forced landing revealed an upslope as they got closer, and the landing touchdown tore off the nose landing gear, the left main wheel, and broke the fuselage behind the rear window. A postcrash engine run, with FAA oversight, using the same fuel aboard at the time of the accident, revealed no engine abnormalities. Using the temperature and dew point reported by the nearest flight service station for the time period of the accident, reference to carburetor icing probability charts would put the flight's probability within the regions classified as, 'visible icing at cruise power', and also within the more restricted, 'serious icing at glide power'. ## Factual narrative On May 18, 2000, about 1620 eastern daylight time, a Cessna A150M, N9843J, registered to a private individual, operating as a Title 14 CFR Part 91 personal flight, crashed in a field in the vicinity of Gainesville, Georgia, following a reported loss of engine power. Visual meteorological conditions prevailed and no flight plan was filed. The airplane received substantial damage and the private-rated pilot and a passenger were not injured. The flight originated from Lawrenceville, Georgia, about 30 minutes before the accident. According to the pilot, he and a friend were sightseeing in the Lake Lanier area at 3,500 feet msl, when they experienced a partial loss of engine power. He completed the checklist items for "engine failure during flight", but lost all engine power, necessitating a forced landing to a vacant field. The touchdown was harder than expected due to upsloping terrain in the direction of the landing. According to the FAA inspector's report, the wreckage was transported to an engine overhaul facility where the Continental O-200A engine, serial no. 253638-A-48, was removed from the airframe, N9834J, and operated with FAA oversight. The fuel used for the postcrash engine run was the same fuel aboard at the time of the accident. The engine started smoothly and operated normally at various power settings with no malfunctions. No evidence of any fluid leakage was noted. Reference to carburetor icing probability charts reveals that an ambient temperature of 84 degrees F and a dew point temperature of 54 degrees F, as reported by the Gainesville, Georgia, AFSS, for the time period of the accident would put the flight's probability within the region labeled, " visible icing at cruise power" and also within the more restrictive region, "serious icing at glide power".
