Incident Overview
An aircraft on a flight from Florencia experienced a runway overrun during landing at Neiva-Benito Salas Airport. The crew had been cleared to descend and were conducting an approach when the aircraft became unstable. After the Ground Proximity Warning System (GPWS) alarm sounded, the captain increased power, causing the aircraft to climb above the glide path. Despite this, the approach was continued.
Landing Details
The aircraft crossed the runway threshold at a height of 140 feet and touched down 1,700 feet past the threshold at intersection Bravo. The runway length is 5,249 feet. After touchdown, the crew initiated braking, but two tyres burst. The aircraft was unable to stop within the remaining runway distance and overran the end, coming to rest in a grassy area.
Occupants and Damage
All 71 occupants evacuated safely. The aircraft sustained damage beyond repair.
Investigation Findings
The official investigation determined the probable cause: the energy accumulated in the set of tires deflated tire n°2, reducing braking effectiveness by 50% due to loss of antiskid in that set. Subsequently, tires n°3 and 4 burst, resulting in 100% loss of braking effectiveness, causing the aircraft to exceed the remaining runway length.
Contributing factors identified were:
- An increase in speed of the VRF by the crew that increased landing length.
- An unstabilized approach completed by the crew.
- Pressure on the crew due to the public order situation in Florencia regarding a possible overnight stay of the aircraft and crew.
