Pakistan : The pilot of a flight that crashed in Pakistan made a mayday call just before losing contact, the airline said.
He also told flight controllers of an engine problem at 16:09 local time (11:09 GMT) on Wednesday, Pakistan International Airlines (PIA) Chairman Azam Sehgal told reporters.
All 48 people on the twin-propeller plane flying to Islamabad were killed.
The carrier has insisted strict checks left “no room for any technical error”. An investigation is ongoing.
“I want to make it clear that it was a perfectly sound aircraft,” Mr Sehgal said.
Irfan Elahi, from Pakistan’s Civil Aviation Authority, told Dawn newspaper: “At the moment, there is no other reason for the plane crash other than the failure of the left engine.”
