A factor was a stuck exhaust valve. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - mech failure/malf, takeoff - initial climb - engine assembly,valve,exhaust - open (contributing factor) - Loss of control - in flight, maneuvering - turn to landing area (emergency) - airspeed - not maintained, pilot in command (cause) ## Analysis The pilot took off from runway 16 and the engine lost partial engine power on initial climb. The pilot decided to return to the airport and stalled the airplane during the turn. The airplane subsequently collided with trees and then the ground off the departure end of the runway. Examination of the wreckage revealed that the airplane collided with the ground in a nose-low attitude. The airplane was destroyed. A post-accident teardown examination of the engine revealed that an exhaust valve was stuck in the open position. ## Factual narrative On October 29, 1999, at 1435 central daylight time, a Cessna 150F, N6444F, lost power and collided with trees on the departure end of runway 16 at Bay Springs, Mississippi.
