Narrative:A Canadian Air Force CH-146 Griffon crashed at an American forward operating base. One British and two Canadian service men lost their lives.
Griffon 434 was tasked to transfer two passengers to and from a Forward Operating Base (FOB). As power was increased for the takeoff a very large dustball developed. Immediately after takeoff, the aircraft drifted forward and to the right, struck a barrier, rotated left, rolled onto its right side and caught fire. One pilot was unharmed, one sustained minor injuries and one passenger suffered serious injuries. The remaining three personnel died. The aircraft was destroyed.
The investigation identified that the aircraft weight exceeded limits, the crew did not complete pre-flight performance calculations and, they attempted the takeoff without knowing the helicopter’s available power. Errors and omissions in critical operational and technical reference material precluded the crew from accurately conducting essential pre-flight calculations had they attempted to do so. Furthermore, evidence existed of a systemic lack of understanding within the CH146 community of how to correctly utilize performance data. Pilot training for operations in DVE was also found to be inadequate.
The investigation identified that the Griffon was deployed to Afghanistan without proper mitigation strategies for certain missions.
