Event Overview
On 26 November 2024, at aerodrome EPCD, a Tecnam P2006T aircraft, registration SP-CLE, was conducting circuit training with simulated asymmetric thrust. The crew consisted of an instructor and a student pilot training for a multi-engine piston (MEP) class rating. The exercise aimed to simulate an approach and landing with one engine inoperative.
Sequence of Events
During the second circuit, the instructor simulated a left engine failure by reducing its throttle to idle. After the fourth turn, on final approach, the student pilot did not maintain adequate altitude or sufficient power from the operating engine, resulting in a descent path below the required glideslope that did not allow a safe landing. The crew executed a go-around.
On the subsequent approach, the instructor again reduced the left engine to idle and decided to land without flaps. The student pilot made a wider circuit than before, increasing the distance between the fourth turn and the threshold of runway 18L. After aligning with the runway, the student again failed to maintain a stable descent, with the approach path below the glideslope (four red PAPI lights observed). The crew did not perform the actions specified in the Aircraft Flight Manual (AFM) and did not set the simulated inoperative engine's propeller to feather. The instructor reminded the student to increase power on the operating engine to stabilize the trajectory. The student increased manifold pressure slightly, but insufficiently to provide adequate power. The instructor did not correct the insufficient power setting, leading to the aircraft touching down just short of the runway threshold. During this premature touchdown, two runway edge lights were damaged. After taxiing to the apron, inspection revealed damage to the landing gear leg and lower fuselage skin. The crew exited the cockpit unaided and sustained no injuries.
Causes
The investigation identified the following causes:
- An unstabilized approach to landing with simultaneous loss of altitude on the descent path.
- The student pilot's actions during the simulated engine failure approach were not in accordance with the AFM and checklist.
- The instructor's lack of reaction to the student pilot's incorrect actions.
Preventive Actions
The operator conducted a refresher training session on standard operating procedures and training methodology for multi-engine aircraft. The event was also discussed with pilots and instructor staff during aviation safety training.
Safety Recommendations
No safety recommendations were issued.
