Incident Overview
A twin-engine aircraft was conducting local training flights at Kota Kinabalu Airport. The crew, consisting of an instructor and a pilot under supervision, had completed several touch-and-go manoeuvres. During a subsequent takeoff, the instructor simulated an engine failure by reducing power on the right engine. In response, the pilot-in-command reduced power on the left engine and initiated emergency braking.
Sequence of Events
The aircraft was unable to decelerate sufficiently within the remaining runway distance. It overran the runway end, struck various obstacles, and lost its undercarriage before coming to rest. Both pilots were uninjured, but the aircraft sustained substantial damage and was declared beyond economical repair.
Operational Context
The accident occurred during a training exercise designed to practice engine-out procedures. The simulation of an engine failure requires coordinated actions between the instructor and the pilot under supervision. In this instance, the combined reduction of power on both engines and subsequent braking did not allow for a stop within the available runway length.
Outcome
The aircraft was destroyed by impact forces and subsequent ground contact. No injuries were reported among the flight crew. The investigation focused on the execution of the emergency procedure and the decision-making process during the simulated engine failure.
