| Confidence Rating: |  Accident investigation report completed and information captured |
Destroyed by explosives and fire after it landed in a minefield. Occupants were unhurt.
Probable cause
Loss of lift in stationary flight caused by the activation of an explosive charge in the execution of an external load flight, which produced a dynamic roll to the left side of the helicopter, and subsequent impact against the ground.
Contributing Factors
Deficient inspection of the landing zone by ground contracting personnel, who failed to identify an explosive device planted at the aircraft landing site allowing terrorist activities to be carried out against a commercial aircraft.
Poor intelligence from the contracting company's Physical Security Department, which was unable to identify terrorist actions planned by illegal groups in its area of influence.
