What happened
On January 31, 2019, a Cessna 172N, registration TG-SYX, was performing a landing at the Ingenio Madre Tierra aerodrome in the municipality of Santa Lucia Cotzumalguapa, Guatemala. The aircraft was operating a private flight with two passengers on board. During the landing phase, a dog ran across the runway at the precise moment of touchdown. Due to the low approach speed of the aircraft, the pilot was unable to execute a go-around to avoid the animal. The aircraft subsequently impacted the ground, resulting in damage to the airframe.
The investigation
The investigation conducted by the DGAC/UIA examined the aircraft's maintenance records, the environmental conditions, and the operational sequence. Investigators confirmed that the Cessna 172N was fully certified, properly equipped, and maintained according to current regulations. The aircraft's weight and balance were within limits, as the flight carried only two passengers and no significant cargo. The investigation also reviewed the pilot's physical and psychological condition, finding no evidence of impairment or physiological limitations that contributed to the event.
Findings
- The primary cause of the accident was a dog crossing the runway during the landing sequence.
- The wet condition of the runway surface at the time of the landing acted as a contributing factor.
- The pilot's low airspeed during the landing phase prevented the execution of an effective go-around maneuver to avoid the animal.
- There were no mechanical failures or malfunctions identified in the aircraft's systems or control surfaces.
Safety action
- It is recommended that access to the landing strip be kept closed to prevent incursions by people or wildlife.
- Where possible, ground personnel should be coordinated via radio or telephone to inspect the runway surface for obstacles or hazards prior to operations.
