PenAir is still trying to determine why an airplane engine failed last week, forcing one of its Saab 340s to make an emergency landing in Sand Point.
PenAir's Mike Walsh said mechanics have removed the flight data recorder, or "black box," which documents a plane’s trip history.
They’re sending the device for inspection to pinpoint the cause of the failure.
In the meantime, the plane will remain in Sand Point.
“We have a great team of mechanics who will get our disabled aircraft back in the air in the near future," said Walsh.
PenAir does not expect any interruptions to flight service is southwest Alaska.
