Flight History
On June 2, 2021, an ATR 72-212A, registration HK5040, operating as flight 4819, departed from El Alcarán Airport (SKYP) in Yopal for a regular passenger flight to El Dorado International Airport (SKBO) in Bogotá. The aircraft carried 4 crew and 56 passengers. The flight proceeded normally with some deviations due to adverse weather. The captain was the pilot flying (PF) and the first officer was the pilot monitoring (PM).
At 22:03 UTC, the crew initiated descent and contacted Bogotá Approach. They were cleared for an ILS approach to runway 13L.
The Incident
During the landing on runway 13L, the aircraft experienced a partial runway excursion. The crew regained control and steered the aircraft back to the runway centerline. After landing, the aircraft taxied to gate F5 via taxiway A5, where passengers deplaned normally.
Injuries and Damage
No injuries were reported among occupants. The aircraft sustained minor damage to its landing gear. Two runway edge lights were damaged.
Weather Conditions
The incident occurred at 17:27 local time (22:27 UTC) during daylight. Weather conditions included heavy precipitation, reduced visibility, and a wet runway. The airport was operating under adverse weather with strong precipitation and wind shear, which after the incident became dangerous for takeoff and landing operations.
Flight Recorder Data
According to flight data recorder analysis, the approach became unstabilized below 300 feet AGL. The approach speed increased to Vapp+19 knots, and the descent rate reached -1166 feet per minute. These parameters were outside the established criteria. The crew did not adequately correct the deviations, leading to a skid after touchdown and a partial runway excursion.
Probable Cause
The investigation determined the probable cause as: Execution of a landing after an unstabilized approach, with parameters outside established criteria during the final segment of the approach (300 feet AGL), which were not adequately resolved by the crew, causing the aircraft to skid after touchdown and partially exit the runway to the right.
Contributing factors included increased approach speed and descent rate, deteriorated weather, wet runway, and crew overconfidence in continuing the approach despite warnings.
