MH370: Malaysia releases Preliminary Report

MALAYSIA has released the Preliminary Report on the investigation into missing Malaysia Airlines Flight MH370.

The five-page report was accompanied by cockpit audio recordings between the pilots and air traffic control, and cargo documents.

The Preliminary Report stated MH370 was the second large commercial passenger aircraft to have gone missing in similar circumstances in the last five years.


“While commercial air transport aircraft spend considerable amounts of time operating over remote areas, there is currently no requirement for real time tracking of these aircraft. This uncertainty resulted in significant difficulty in locating the aircraft in a timely manner,” the reported stated.

As a result, the Malaysian Air Accident Investigation Bureau made the following safety recommendation to the International Civil Aviation Organisation (ICAO):

“It is recommended that the International Civil Aviation Organisation examine the safety benefits of introducing a standard for real time tracking of commercial air transport aircraft.”

Here’s a snapshot of what the Preliminary Report contained:

OPERATOR: Malaysia Airlines (MAS)
ENGINES: 2 Rolls Royce RB211 Trent 892B17
TYPE OF FLIGHT: Scheduled commercial air transport
PERSONS ON BOARD: 227 passengers & 12 crew
