TAWS mandate urged by Buddha Air probe

All operators in Nepal could soon be required to install Terrain Awareness Warning Systems following recommendations made in the wake of last September’s Buddha Air crash, according to the Deccan Herald.

Human error was cited as the reason behind the air crash that killed all 19 on board with a Nepalese commission adding that pilot fatigue coupled with poor visibility were the main factors behind the incident.

The accident occurred near Kathmandu airport as the Beech 1900D turboprop operated by Nepalese carrier Buddha Air was returning from a mountain sight-seeing flight.

The five member investigation team’s report concluded that flight crew did not follow standard route that led to a loss of situational awareness, resulting in the accident.

“The aircraft was found flying in 5,000 ft above the ground against the standard norm which requires to maintain 6,000 ft elevation,” it said. “As the aircraft started descending inside the cloud it hit tree tops on the hills.”

“Incompatible and incorrect procedure contrary to standard operating procedure led to the accident,” added the head of the five member commission.
