PETALING JAYA: Malaysia Airlines has explained the anomalies noted in the Interim Statement released in conjunction with the one-year anniversary of the disappearance of Flight MH370.
It clarified that another underwater locator beacon had been installed with the Solid State Cockpit Voice Recorder (SSCVR) on the plane and its battery life was still valid on the day it went missing on March 8 last year with 239 passengers and crew.
The airlines, in a statement yesterday, said that the SSCVR battery would have been transmitting for 30 days upon activation when immersed in water.
On Sunday, the 600-page factual information released alongside the Interim Statement on MH370, stated that investigators found the battery of the flight data recorder's underwater locator beacon had expired in December 2012, well over a year before the plane vanished.
MAS admitted the finding, calling it a "maintenance scheduling oversight".
Investigators also said that 221kg of lithium-ion batteries carried in the aircraft did not pass through security checks.
The report stated that the batteries, from Motorola Solutions Penang, were assembled and packed in Bayan Lepas on March 7 before being transported by truck to the KL International Airport.
On this matter, MAS said the consignment of Motorola lithium-ion batteries was physically inspected by MASKargo personnel in Penang and Customs inspectors prior to being sealed before it left the Penang Cargo Complex.
"The inspection procedures followed for this consignment are in line with those defined by the International Civil Aviation Organisation.
"MAS has already taken significant steps to improve safety in response to the loss of MH370. The airline has consistently adhered to the standards required by the International Air Transport Association operational safety audit programme, as part of its compliance with the association's membership requirements.
"We have upgraded our Aircraft Communication Addressing and Reporting System across the entire MAS fleet. MAS will continue to review its operations and procedures to enhance flight safety," it said.
