Operators in Malaysia have followed Petronas Carigali’s lead and cancelled their contracts with Boustead subsidiary MHS Aviation for the charter of EC225 helicopters because of safety concerns.

The trio of partners has served MHS Aviation with 90-day notices of termination to cancel their contract dated 29 June, 2011.
