GEORGE TOWN: The final report on the Long Lellang helicopter crash is expected to be published within a year, Transport Minister Anthony Loke said.

It was reported yesterday that more than a month after a Bo-105 helicopter crashed in Long Lellang on Sept 8, killing five people, investigators had yet to determine the cause of the crash.

The preliminary report released by the Air Accidents Investigation Bureau (AAIB) stated that the safety investigation was ongoing, with the available factual data still at a preliminary stage.

"This is just a preliminary report. The final report will be published later, within a year," he told reporters after the launch of Penang's first electric bus.
