Amateur-built KELLY D N5172S accident near Brandon, Mississippi

Probable cause

A total loss of engine power during takeoff for reasons that could not be determined because postaccident examination did not reveal any anomalies that would have precluded normal operation.

NTSB analysis

The flight instructor and student pilot were preparing to take off to the west. Following a normal magneto and carburetor heat check, the student took the controls for the takeoff. Shortly after liftoff, the engine suddenly lost all power. The flight instructor took the controls and maneuvered the airplane for a forced landing. The airplane struck trees and sustained substantial airframe damage. A wreckage examination found no evidence of a pre-existing mechanical malfunction or failure, and there was adequate fuel on board for the flight. Although there were some small flakes of sealant in the fuel tanks, no obstructions were found. A review of meteorological data revealed that the airplane was being operated in conditions conducive to serious carburetor icing at glide power but not at takeoff power. Thus, the reason for the loss of engine power could not be determined.
