Aviation accident WPR21FA143

The pilot’s failure to adequately respond to an encounter with whiteout conditions, which resulted in the helicopter’s collision with terrain. Contributing to the accident was the (1) operator’s inadequate pilot training program and pilot competency checks, which failed to evaluate pilot skill during an encounter with inadvertent instrument meteorological conditions, and (2) the Federal Aviation Administration principal operations inspector’s insufficient oversight of the operator, including their approval of the operator’s pilot training program without ensuring that it met requirements. Contributing to the severity of the surviving passenger’s injuries was the delayed notification of search and rescue organizations.
