Accident Overview
On 9 September 2018, at Mielec Airport (EPML), a Piper Seneca PA34 200T, registration SP-ROY, was conducting training flights for a multi-engine piston (MEP) class rating. The flights involved circuits and practice of emergency procedures including engine failure during takeoff and approach. All flights were performed on runway 09 using touch-and-go landings.
Sequence of Events
During the 13th circuit, while on the downwind leg, the instructor closed the left engine fuel valve to simulate a left engine failure. The student pilot carried out the engine failure procedure and continued the approach with the engine inoperative. Near the third turn, the instructor restarted the left engine but left it at idle power. Because the left throttle was at minimum, the landing gear warning horn and lights activated. The instructor told the student that landing gear should be extended on final.
As the crew continued the approach, they focused on maintaining a proper approach profile with asymmetric thrust. The weather conditions included a left crosswind and light turbulence, requiring increased attention. After stabilizing on final, the student extended flaps to 10° but did not lower the landing gear. The aircraft landed with the gear retracted, sliding on the runway for about 250 meters before stopping on the concrete portion. The crew then turned off the magnetos and master switch and exited the aircraft unaided.
Injuries and Damage
Both pilots were uninjured. The aircraft sustained damage to the lower fuselage skin and propellers. After being lifted by a crane and the landing gear extended, the aircraft was towed off the runway.
Contributing Factors
A contributing factor was the instructor's long break from MEP(L) training—approximately one year—during which he flew commercial operations. This was his first MEP(L) training flight after the hiatus.
Cause
The cause of the accident was: 1. Failure to perform the pre-landing checklist. 2. Failure to verify proper landing gear extension. 3. Failure to make the required radio call confirming aircraft configuration before landing.
Preventive Actions
Following the accident, the operator conducted refresher training for instructors training on retractable-gear aircraft, covering emergency procedures and the use of checklists during various flight stages.
Recommendations
No recommendations were issued by the Polish accident investigation commission.
