What happened
On 19 July 2024, a Socata TB-9 Tampico, registration SP-TAI, was conducting familiarization flights at Bagicz (EPKG) aerodrome. At the time of the incident, preparations were underway for the Sunrise Festival, which had resulted in the installation of barriers and fencing near the southern edge of the airstrip.
Following an initial flight, the pilot prepared for a second flight with two passengers. The passengers were seated in the rear of the cabin. During the takeoff roll, upon reaching a speed of approximately 50 knots, the aircraft's nose lifted beyond the recommended takeoff angles. The pilot attempted to correct the pitch, but the aircraft failed to respond to control inputs and began to veer to the left. After a takeoff roll of approximately 550 meters, the aircraft collided with the fence positioned at the edge of the airstrip. There were no injuries to the pilot or passengers, though the aircraft sustained serious damage.
The investigation
The PKBWL examined video recordings captured by the passengers on mobile devices to analyze the flight sequence. The investigation reviewed the aircraft's airworthiness, maintenance records, and weight and balance calculations. The investigators also examined the aircraft's configuration, specifically the position of the flaps and the trim tab, as well as the pilot's use of pre-flight procedures.
Findings
- The aircraft was airworthy and all necessary technical documentation was in order.
- The pilot held the appropriate ratings and licenses for the flight.
- The aircraft was balanced toward the rear, though within acceptable limits.
- The pilot did not use a checklist prior to takeoff.
- The improper configuration of flaps or trim, potentially combined with the rearward center of gravity, contributed to the excessive nose-up pitch.
- The presence of the fence near the active runway area was a contributing factor.
