Malaysia Airlines' MASwings will phase out its remaining eight Fokker 50 aircraft by April next year.
These will be replaced by ATR 72-500s, MASwings managing director, Mohd Salleh, is reported as saying to Bernama, Malaysia's official news agency.
He says the Fokker 50 is no longer viable owing to high operational costs.
MASwings already operates four ATR72-500son routes between the eastern Malaysia provinces of Sabah and Sarawak, says Salleh.
"We are expecting our fifth craft to be delivered some time at the end of August or in early September."
"The sixth will be delivered at the end of September and the seventh by December."
"The three remaining aircraft are expected to arrive in February and March next year," he says, adding that by April the last Fokker 50 would have been phased out.
