Circumstances:
The approach and landing at Monterrey-General Mariano Escobido Airport were completed by night and poor weather conditions with limited visibility due to heavy rain falls and mist. At the time of the accident, runway 29 threshold was displaced by 900 metres, reducing the landing distance available from 3,000 metres to 2,100 metres due to construction works. Following a wrong approach configuration, the aircraft landed too far down a wet runway and was unable to stop within the remaining distance. It overran, lost its undercarriage and came to rest 60 metres further with the right partially torn off. 11 passengers were injured while 79 other occupants were unhurt.

Circumstances:
Following an uneventful flight from Florencia, the crew was cleared to descend to Neiva-Benito Salas Airport. On approach, the aircraft was unstable and after the GPWS alarm sounded, the captain increased power and gained altitude, causing the aircraft to climb over the glide. The approach was continued and the airplane passed over the threshold at a height of 140 feet and eventually landed 1,700 feet past the runway threshold at intersection Bravo (the runway is 5,249 feet long). After touchdown, the crew started the braking procedure but two tyres burst and the aircraft was unable to stop within the remaining distance. It overran and came to rest in a grassy area. All 71 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The energy accumulated in the set of tires deflated the tire n°2, reducing the braking effectiveness by 50% due to the loss of the antiskid of that set in the same proportion, and subsequently the loss of 100% of the effectiveness of braking when tires n°3 and 4 burst successively, causing the aircraft to exceed the remaining runway length leading to the accident situation.
The following contributing factors were identified:
- The increase in speed of the VRF by the crew that increased the landing length,
- An unstabilized approach completed by the the crew,
- The pressure exerted on the crew due to the public order situation in the city of Florence for the purpose of a possible overnight stay of the aircraft and consequently the crew.
