Incident Overview
A training flight at Lille-Lesquin Airport ended in a crash on the runway during a touch-and-go maneuver. The aircraft was completing several touch-and-go landings when, on final approach just prior to touchdown, it went out of control and struck the ground. The impact damaged the aircraft beyond repair. Both pilots—student Jean-Claude Timmermans and instructor Étienne Lemmens—were killed.
Investigation Findings
Investigators examined the wreckage and flight data to determine the sequence of events. The aircraft had been performing routine training circuits when the accident occurred. No pre-existing mechanical issues were reported before the flight.
Probable Cause
The official investigation determined that one of the propellers went into reverse mode just prior to touchdown for undetermined reasons. This reversal caused a sudden loss of speed and height, leading to the loss of control and subsequent crash.
