# NTSB ATL07CA072: Cessna C-150G, N6380S, Enterprise, AL, April 10, 2007 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Data collection · Final report - Date: April 10, 2007, 15:45 local (20:45 UTC) - Place: Enterprise, AL - Coordinates: 31.293056, -85.893058 - Nearby events: https://openairdocs.org/map.md?lat=31.2931&lon=-85.8931&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report June 27, 2007 - Report: Approved by Office Director - Parties: Birmingham FSDO - NTSB case key (mKey): 65791 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL07CA072 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65791/pdf - Page: https://openairdocs.org/ntsb/ATL07CA072 ## Probable cause The CFI's attempted takeoff with known deficiencies in the engine which resulted in a loss of engine power, a forced landing on muddy terrain, and a nose over. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, takeoff - roll/run - reason for occurrence undetermined - operation with known deficiencies in equipment - attempted, pilot in command(cfi) (cause) - Forced landing, emergency landing after takeoff - Nose over, emergency landing after takeoff - terrain condition - muddy ## Analysis According to the Certified Flight Instructor (CFI), prior to takeoff and during the engine performance check, the left and right magnetos checked out okay, but the engine ran rough. He applied carburetor heat for a while and the engine smoothed out. He taxied out onto runway 05. During takeoff the engine continued to run rough and the stall warning horn was heard. He stated that he had planned to abort the takeoff but the airplane started to lift off the runway and he was at a point of no return. As the pilot continued to climb out the engine started loosing power and the stall warning horn was getting louder. The pilot immediately pulled the carburetor heat lever and the engine rpm dropped. The pilot made a forced landing in a field north of the airport. During landing the nose wheel stuck in the mud and the airplane flipped over and landed inverted. The pilot had not submitted an NTSB Form 6120.1 pilot operator report at the time of this report. Examination of the airplane by an FAA inspector found substantial damage to the vertical stabilizer, and buckling of the cockpit and fuselage. There were no mechanical or engine problems discovered during the post-accident examination of the airplane. ## Factual narrative According to the Certified Flight Instructor (CFI), prior to takeoff and during the engine performance check, the left and right magnetos checked out okay, but the engine ran rough.

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.
