What happened
On June 3, 2020, a Cessna 182E, registration TG-RAU, departed from the aerodrome in Cobán, Alta Verapaz, Guatemala, at 10:05 local time. The flight was being operated by a private pilot with two passengers on board, intended for a flight to the village of Bella Vista Sáctela and a subsequent return to Cobán.
During the flight, the pilot encountered adverse weather conditions, including low visibility, cloud cover, strong winds, and moderate turbulence. These conditions prompted the pilot to decide to return to the departure airfield. During the sequence of events, the aircraft experienced a structural failure of the landing gear, resulting in an impact with the ground and significant damage to the airframe.
The investigation
The DGAC/UIA investigation focused on the mechanical integrity of the aircraft and the environmental factors present during the flight. Investigators examined the aircraft's maintenance records, which showed that the aircraft had recently undergone a 100-hour inspection. The investigation also reviewed the aircraft's systems, finding that all flight systems were functioning normally prior to the impact and that the aircraft was properly certified and maintained according to manufacturer standards.
Physical inspection of the wreckage revealed severe impact damage. Specifically, investigators identified a fracture in the right landing gear and damage to the right stabilizer and elevator components. The investigation also looked into the pilot's physiological and psychological state, finding no evidence of impairment or negative human factors contributing to the accident.
Findings
- The primary cause of the accident was the fracture of the right landing gear caused by material fatigue accumulated over the component's service life.
- Adverse meteorological conditions, including strong winds and moderate turbulence, were present during the flight.
- The aircraft's maintenance program required a main landing gear inspection every 200 hours; the aircraft had recently completed a 100-hour service, meaning the specific gear inspection was not yet due.
- There were no injuries to the pilot or the passengers, and all occupants evacuated the aircraft unassisted.
