Investigation Summary
The flight was a contract mission for the U.S. military's Air Mobility Command, intended to transport three U.S. Army soldiers and 400 pounds of mortar illumination rounds to Farah. Despite the hazardous terrain of Afghanistan, the crew chose to fly a direct western route over high mountain peaks rather than the established, safer route to the south. CVR recordings revealed a lack of professional discipline, with the pilots joking about the 'fun' they were having and comparing the low-level mountain flying to Star Wars. As the aircraft proceeded, it entered a box canyon. The crew realized too late that the valley 'petered out' and attempted a steep turn with partial flaps deployed. The aircraft's performance was insufficient at the high density altitude, leading to an aerodynamic stall. The investigation highlighted significant organizational failures, including Blackwater's violation of its own policy requiring at least one pilot to have 30 days of in-country experience. Furthermore, the lack of flight tracking infrastructure and the absence of a filed flight plan meant the aircraft was not reported missing until it was significantly overdue, and the wreckage was only found when a military aircraft detected the ELT signal.
Final Conclusions
The National Transportation Safety Board (NTSB) determined the probable cause was the captain's inappropriate decision to fly a nonstandard route and his failure to maintain adequate terrain clearance. Contributing to the accident were the lack of oversight by Presidential Airways, the Federal Aviation Administration, and the Department of Defense. The NTSB also noted that the crew likely suffered from hypoxia due to the high altitude and lack of supplemental oxygen, which impaired their judgment. The investigation concluded that Specialist Harley Miller was the sole initial survivor of the impact, as both pilots were ejected from the aircraft. Miller survived for 8 to 10 hours but died due to the delay in search and rescue operations caused by the lack of flight tracking and a filed flight plan.

Systems & Failure Modes
Emergency Locator Transmitter (ELT)
The ELT functioned correctly after the impact, and its signal was eventually picked up by a passing U.S. military aircraft, leading rescuers to the site.
Flaps
The pilot requested 'quarter flaps' during the final turn to increase lift and decrease stall speed, but the maneuver was attempted too late to clear the terrain.
Interesting Facts
- 01The aircraft was flying at an altitude where supplemental oxygen was required, but none was used, leading to suspected hypoxia.
- 02One passenger, Specialist Harley Miller, survived the crash for approximately 8 to 10 hours but died of exposure and injuries.
- 03The crew had only been in Afghanistan for 13 days, violating the company's 30-day experience policy.
- 04No flight plan was filed, and the aircraft lacked tracking equipment, delaying search and rescue by several hours.
- 05The wreckage was located at an elevation of approximately 14,650 feet.
Safety Actions & Advisories
Flight Tracking Mandate
Following the crash, Blackwater aircraft were refitted with flight trackers to ensure real-time monitoring of aircraft positions.
Crew Experience Policy Enforcement
A new policy was strictly enforced requiring all flights to have at least one crew member with significant in-country experience in the cockpit.
Known Controversies & Unanswered Questions
Survivability and Search Delay
Reference ↗The NTSB report and subsequent media coverage highlighted that Specialist Harley Miller would likely have survived if search and rescue had reached him within eight hours, sparking criticism of Blackwater's lack of flight tracking and the military's oversight.
