# NTSB MIA96LA036: Cessna 150J, N60758, Orange Springs, FL, December 6, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: December 6, 1995, 10:00 local (15:00 UTC) - Place: Orange Springs, FL - Coordinates: 29.420007, -82.209533 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=29.4200&lon=-82.2095&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report February 14, 1996 - Report: Approved by Office Director - NTSB case key (mKey): 37956 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA96LA036 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/37956/pdf - Page: https://openairdocs.org/ntsb/MIA96LA036 ## Probable cause THE PILOT'S IMPROPER USE OF CARBURETOR HEAT RESULTING IN ENGINE FAILURE DUE TO CARBURETOR ICE. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, approach - vfr pattern - base leg/base to final - weather condition - carburetor icing conditions - carburetor heat - improper use of, pilot in command (cause) - fuel system,carburetor - ice - Forced landing, descent - emergency - On ground/water encounter with terrain/water, landing - roll - terrain condition - high vegetation ## Analysis THE PILOT REDUCED ENGINE POWER ON THE DOWNWIND LEG OF THE LANDING APPROACH. WHEN ON BASE LEG HE ADVANCED THE THROTTLE TO CLEAR THE ENGINE AND THE ENGINE QUIT. ATTEMPTS TO RESTART WERE UNSUCCESSFUL AND THE AIRCRAFT LANDED IN AN AREA OF HIGH VEGETATION SHORT OF THE RUNWAY. AFTER THE ACCIDENT THE ENGINE WAS STARTED AND OPERATED TO FULL POWER WITH NO EVIDENCE OF FAILURE OR MALFUNCTION. THE PILOT DID NOT REMEMBER WHEN HE APPLIED CARBURETOR HEAT DURING THE APPROACH. ACCORDING TO CARBURETOR ICING PROBABILITY CHART THE AIRCRAFT WAS OPERATING IN CONDITIONS CONDUCIVE TO SERIOUS CARBURETOR ICING AT GLIDE POWER. ## Factual narrative On December 6, 1995, about 1000 eastern standard time, a Cessna 150J, N60758, registered to a private owner, crashed following loss of engine power at the 85th Avenue Airpark, Orange Springs, Florida, while on a 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the private-rated pilot was not injured. The flight originated from Orange Springs, about 0845. The pilot stated he reduced engine power while abeam the arrival end of the runway on the downwind leg of the traffic pattern. When he turned based leg he advanced the throttle to clear the engine. The engine quit. Attempts to restart the engine were unsuccessful. The aircraft contacted the ground about 100 yards short of the runway and collided with small trees and brush. The pilot stated he does not remember when he applied carburetor heat during the approach to land. A mechanic found the carburetor heat on after the accident. Postcrash examination of the engine was performed by a mechanic. All fuel lines were unobstructed and contained uncontaminated fuel. The air inlet was unobstructed. The engine was started and operated to full power with no evidence of failure or malfunction. The carburetor heat system operated normally. According to carburetor icing probability curves the aircraft was operating in conditions conducive to serious carburetor icing at glide power. ## Aircraft - Registration: [N60758](https://openairdocs.org/deregistered/N60758-2000-06-19), registration cancelled 2000-06-19, S/N 15070553 (OpenAirDocs) - Reported make and model: CESSNA 150J - Registry model: [Cessna 150J](https://openairdocs.org/model/cessna-150j) (registry code 2071820) (OpenAirDocs) - Category: Airplane - Serial number: 15070553 - Airframe hours: 4850 - Engines: CONTINENTAL O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Jon Allen Cockes - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: Annual, January 18, 1995, 29 hours before - Departed: X60, WILLISTON, FL - Airport: FD02, 85th Avenue Airstrip, runway 33, 3,000 × 150 ft, grass/turf ## Flight crew As NTSB recorded them.
