PETALING JAYA: The Air Accident Investigation Bureau (AAIB) final report on its investigations on an air crash involving a private jet at Elmina, Shah Alam in Aug last year concluded that human error by flight crew was the primary cause of the accident.
The report released by the Transport Ministry on Friday (Aug 16) revealed that the accident was caused by the accidental extension of the lift dump spoilers by the two-man flight crew during a pre-landing checklist routine.
The report also said other contributing factors led to the accident namely deviations from standard operating procedures, inadequate crew training, regulatory grey areas and deficiencies in communication and decision-making.

Lift dumpers or spoilers are devices used to reduce an aeroplane's lift, thereby increasing drag and are commonly located on the wings.
It is either deployed or retracted in default.
When an aircraft needs to slow down, pilots deploy the lift dumpers which extend over the wings to decrease lift and increase drag simultaneously.

However, during landing, lift dumpers in most newer aircraft activate automatically to keep speed more manageable.
On Aug 17 last year, the private jet, a Beechcraft Model 390 had departed Langkawi International Airport en route to Subang Airport crashed at Bandar Elmina just two minutes before landing, killing 10 people.
Those killed were six passengers, two pilots and two others who were hit by the plane on the ground namely an e-hailing driver and a delivery rider on a motorcyclist.
