What happened
While performing a flight from Kabul toward Jalalabad, the crew of an AN-26 experienced mechanical difficulties. During this period of technical instability, the aircraft crossed into Pakistani airspace without receiving prior authorization. Following its entry into the restricted airspace, it is believed that a pilot from the Pakistan Air Force engaged the plane with a fighter aircraft. The subsequent crash occurred in the vicinity of Parachinar.
Search teams located the debris field the next morning. There were no survivors from the accident, as all 34 occupants on board were killed during the event.
Findings
Investigations into the incident suggest that the primary reason for the loss of the aircraft was that it was shot down by a Pakistani military fighter after entering their airspace without clearance.
