Incident Overview
According to the official investigation, the pilot stated that the left engine lost power during takeoff.

The left wing of the aircraft struck the crane, after which the aircraft descended and crashed upright into the bay.
Pilot's Account

The pilot reported that he did not hold a multi-engine rating. He further stated that he had 6 hours of multi-engine pilot-in-command time and no dual instruction in multi-engine aircraft.
Aftermath
The left engine separated from the aircraft during the crash and was not recovered. No other details regarding occupants, injuries, or damage were provided in the source.
