What happened
On February 22, 2019, a student pilot was performing solo takeoff and landing maneuvers at the Requena aerodrome in Spain. During the final landing attempt of the session, the pilot lost control of the PIPER PA28-161, registration EC-JDP, shortly after touchdown on runway 30.
As the aircraft decelerated on the runway, it veered toward the left side of the pavement. The aircraft exited the runway via taxiway H1, traveling through a gravel area and onto the apron. During the excursion, the aircraft collided with two other parked aircraft and struck a hedge. The impact caused major damage to the PIPER PA28-161, including a deformed wing, damaged landing gear, and structural damage to the fuselage. One of the collided aircraft also sustained extensive damage, while the second aircraft suffered only minor damage to its wing leading edge. The pilot was uninjured.
The investigation
The CIAIAC investigation focused on two primary areas: the approach speed and the functionality of the aircraft's braking system. Flight tracking data and the pilot's personal flight recorder indicated an approach speed of approximately 78 knots, which was slightly above the operator's recommended 75 knots for a 10-degree flap configuration but within a range that should have allowed for a safe stop given the touchdown point.
Investigators examined the braking system for potential mechanical failure. The pilot reported that applying the left brake caused the left wheel to lock, while the right brake appeared unresponsive. However, the inspection of the brake pads, hydraulic lines, and reservoir revealed no signs of leaks, malfunctions, or irregularities. The brake pads were found to be in good condition and capable of further service.
Findings
- The primary cause of the accident was the loss of control of the aircraft due to inadequate management of the directional control system by the pilot.
- The pilot experienced a wheel lock on the left side during braking, which induced a significant leftward yaw.
- The aircraft's braking system was found to be in proper working order with no mechanical or hydraulic defects identified.
- The approach speed was not excessive enough to prevent a safe stop on the remaining runway length.
