Incident Overview
On September 6, 2024, at Poznań-Ławica Airport (EPPO), a Tecnam P2008JC aircraft, registration SP-SME, was conducting a landing with overshoot on runway 10. During the landing roll, the pilot was unable to properly decelerate the aircraft. As the landing roll concluded, the pilot steered onto a taxiway and subsequently onto the grass, where the aircraft came to a stop. Neither the aircraft nor any airport infrastructure sustained damage.
Technical Inspection
Following the incident, a technical inspection of the aircraft revealed a cracked seal in the brake caliper of one of the landing gear wheels. This defect resulted in a leak and loss of hydraulic fluid pressure in the brake system, compromising its ability to provide symmetrical braking force to the wheels.
Cause
The cause of the incident was determined to be a mechanical failure of the aircraft's brake system, specifically a loss of hydraulic pressure due to a seal failure, which prevented uniform braking of the wheels.
Contributing Factor
A contributing factor was the landing with overshoot, which likely placed additional demands on the braking system.
Safety Actions
The investigating organization proposed two preventive actions: discussing the incident with personnel to emphasize proper procedures when facing brake system problems during landing, and including information about the incident in the ATO safety bulletin. No safety recommendations were formulated by the commission.
