The wreckage of a plane that crashed off Molokai has arrived in Honolulu.

Makani Kai Air owner Richard Schuman said Thursday a salvage dive team was able to recover the plane’s single engine.

The engine lost power soon after the plane took off from Kalaupapa last week, forcing a water landing. Hawaii Health Director Loretta Fuddy was a passenger and the only fatality of the nine people onboard.

Schuman says the wreckage and the engine arrived in Honolulu on a ship Wednesday night.

He says the engine will be transported to a factory of the engine manufacturer, where the National Transportation Safety Board will determine what caused it to fail.

The NTSB initially believed the plane couldn’t be recovered but it was eventually spotted off the north shore of Molokai.
