“The flight crew lost visual contact with the ground and external surroundings,” he noted.
The loss of visual contact with the ground forced the helicopter into a hard landing and it subsequently rolled onto its right side.
Blaming the crew, the Bureau said that other factors aside the visual disorientation contributed to the incident.
The factors include:
- inappropriate landing technique used,
- non-adherence to company procedures for known or anticipated brownout conditions during landing,
- lack of risk assessment,
- limited landing site preparation and,
- planning prior to commencement of the flight.
In its recommendation, AIB advised the Office of the National Security Adviser to “consider whether the Presidential Air Fleet Unit should be involved in the coordination and preparation of all high profile Executive VIP mission (flights) in order to ensure that all Executive VIP flights are conducted in accordance with the PAF Unit’s Standards and in line with its approved operating procedures.”
