What happened
On December 7, 2011, a Piper Aircraft, Inc. PA-23-250, registered as TG-MIT, performed an emergency landing at La Aurora International Airport in Guatemala. During the approach, the aircraft experienced a failure in the landing gear system. The pilot managed to execute a controlled emergency landing on the grass area located between the main runway and the taxiway, specifically at the intersection of taxiways K and L. While the aircraft sustained significant damage to the landing gear doors and the lower wing structure, there were no injuries to the pilot.
The investigation
The DGAC/UIA investigation examined the aircraft's maintenance records, the pilot's experience, and the physical wreckage. Investigators analyzed the landing gear assembly and found evidence of a severe hydraulic fluid leak and a fractured actuator end. The investigation also reviewed the engine and propeller, noting that the propeller blades showed impact damage consistent with the engine being at low power during the touchdown. The investigation confirmed that the aircraft's documentation, including airworthiness and insurance, was valid, and the fuel onboard was of the correct grade and uncontaminated.
Findings
- The primary cause of the accident was an operational error characterized by high approach speed and/or situational disorientation during the landing phase.
- A heavy landing caused the breakage of a landing gear actuator.
- The landing gear system was already compromised prior to touchdown, evidenced by a fractured actuator end and hydraulic fluid leakage.
- The pilot's high-speed approach resulted in a hard impact that damaged the aircraft's structure and landing gear components.
