Preliminary crash report offered

HONOLULU (AP) — Federal investigators have released a preliminary report that offers details but not a cause of a deadly helicopter crash in Hawaii.

The Honolulu Star-Advertiser reported Wednesday that the National Transportation Safety Board report released Wednesday lists the initial findings of its investigation into the April 29 crash on Oahu.

The accident killed 28-year-old pilot Joseph G. Berridge and two female passengers, 28-year-old Ryan McAuliffe and 76-year-old Jan Burgess.

The report says witnesses reported “an odd noise followed by a loud metallic bang” before observing “the helicopter in a nose low attitude descending rapidly.”

An NTSB official says a final report including a probable cause is likely to take 12 to 24 months to complete.
