What happened
During a flight from Quito to Cuenca-Mariscal La Mar Airport, the flight crew began their descent toward Runway 23. At the time of arrival, the destination airport was experiencing adverse weather, characterized by rainfall and a contaminated runway surface. During the approach, the pilot-in-command descended below the established glide path, crossing the runway threshold at an altitude of 37 feet rather than the prescribed 50 feet.
The aircraft type touched down 277 meters beyond the threshold while traveling at a speed of 127 knots. Upon landing, the crew deployed the reverse thrust and spoilers. In an attempt to decelerate on the slippery surface, the captain engaged the autobrake system; however, the braking action proved insufficient to stop the plane within the available runway length. As the aircraft failed to stop, the captain executed a deliberate right turn, which resulted in a ground loop. The aircraft subsequently overran the runway and came to a stop in a nearby grassy area. The aircraft sustained damage that was determined to be beyond repair.
Findings
- The landing occurred on a contaminated runway due to active rainfall.
- The approach was flown below the recommended glide slope height.
- Inadequate braking action prevented the aircraft from stopping before the end of the runway.
