Narrative:
A Douglas DC-3C, registration HK-3293, sustained a runway excursion after landing at San Felipe Airport in Colombia.
The aircraft carried humanitarian aid and several aid workers to San Felipe because of recent floodings in the region.
After touchdown the aircraft moved to the left of the runway. The pilot tried to regain directional control but the aircraft veered off the left side of the runway. The aircraft swung and came to rest in a ditch besides the runway. A fire broke out in the left engine which was extinguished by the crew during the post-impact emergency procedures.

Probable cause(s):
The investigation determined that the accident was due to the following probable causes:
Lateral runway excursion, as a result of loss of ground control caused by loss of air pressure in the left undercarriage tyre, as a result of FOD penetration into the tyre during the landing run.
Deficient risk management by the San Felipe airfield operator (SKFP) for the execution of operations at the airfield.
Contributing Factors:
Absence of a ramp FOD control programme (SKFP) by the aerodrome operator.
