What happened
On February 7, 2020, a private pilot was conducting solo practice circuits at the Milewo (EPMX) landing field. Following a successful pre-flight inspection and engine warm-up, the pilot completed several circuits. During the third circuit, the pilot landed on the runway heading 360 degrees.
As the aircraft entered the landing roll, the pilot attempted to decelerate using the manual hydraulic brake lever. However, the braking action failed to significantly reduce the aircraft's speed. Relying on muscle memory from previous experience with aircraft featuring toe brakes, the pilot instinctively applied the rudder pedals to assist in braking. This action caused the aircraft to veer approximately 30 degrees to the left.
In an attempt to avoid obstacles, the pilot increased engine power to steer the aircraft back toward the landing heading of 036 degrees. This maneuver was unsuccessful, and the aircraft exited the runway, coming to a stop in a young orchard. The pilot, who was the sole occupant and wearing a seatbelt, exited the aircraft without injury. The CTLS sustained damage to the propeller, cockpit glazing, leading edges of both wings, the left wing flap, both horizontal stabilizers, and the landing gear fairings.
The investigation
The PKBWL investigation confirmed that the pilot held valid flight qualifications and a current medical certificate. The aircraft, registration OM-M4194, was documented as airworthy. The investigation established that meteorological conditions were favorable (VMC) and did not contribute to the incident. Technical examination of the aircraft revealed that the hydraulic main landing gear brake was fully functional.
Findings
- The primary cause of the incident was the loss of directional control during the landing roll due to improper use of the main landing gear brake.
- The pilot's experience on the specific CTLS type was very limited, totaling only 2 hours and 15 minutes.
- The pilot's previous training and habits on aircraft with different brake configurations (toe brakes) contributed to the error.
