DALLAS — Federal accident investigators issued a preliminary report on the crash of a small plane that killed all 10 people on board at a Dallas-area airport.
The National Transportation Safety Board report offers no new insights into what caused the June 30 crash of the twin-engine Beechcraft BE-350 King Air at Addison Airport.
The report quotes one witness as saying the aircraft's engines sounded quieter than usual and seemed to lack sufficient power for takeoff when it lifted off the runway. Witnesses said the plane banked left before crashing into a hangar.
The aircraft's cockpit voice recorder captured a crew member's comment that there seemed to be a problem with the left engine. Five seconds later, three alarms sounded, warning pilots that the plane was banked too sharply to one side. The recording ended moments later.
The NTSB report says technical experts will be convened to further review the recording.
The private plane was not required to have a flight data recorder, which tracks the performance of virtually every system on board. Federal investigators are relying on physical evidence at the crash site, video, radar information and witness accounts to determine the cause of the crash.
Two crew members and eight passengers died when the twin-engine plane crashed. It was scheduled to fly to St. Petersburg.
