What happened
On July 23, 2013, a Cessna T206H, registration TG-GOM, was performing an approach to a grass airstrip located at Finca Belén, within the municipality of Santa Lucia Cotzumalguapa, Escuintla. The runway, measuring 700 meters in length and 30 meters in width, had been subjected to heavy rainfall earlier that morning, leaving the surface saturated with water.
During the landing sequence, the aircraft touched down significantly beyond the normal touchdown point. Due to the excessive touchdown speed and the lack of effective braking on the waterlogged grass, the pilot was unable to decelerate the aircraft within the remaining runway distance. The aircraft overran the end of the strip, coming to rest approximately 15 meters past the southern threshold. The impact caused the nose gear to detach, damage the left main landing gear support, and result in structural damage to the wingtip and propeller hub.
The investigation
The DGAC/UIA investigation examined the aircraft's maintenance records, which showed the plane had undergone its 100-hour service in April 2013 and was within its operational limits. Investigators also reviewed meteorological data, confirming that while flight conditions were generally favorable, the recent rain had created a high level of moisture on the runway. The investigation included an analysis of the aircraft's mechanical state, finding no evidence of engine failure, fuel contamination, or malfunctions in the navigation or communication systems. The crew's performance was evaluated in the context of the runway conditions and the landing technique employed.
Findings
- The aircraft was in a fully airworthy condition with all required documentation and maintenance up to date.
- The runway surface was saturated with water due to morning rainfall, significantly reducing braking effectiveness.
- The pilot performed a long landing at an airspeed exceeding the calculated approach speed for the threshold.
- The pilot failed to adequately plan the landing maneuver in consideration of the known wet runway conditions.
