The family of two brothers killed in a skydiving crash in May has filed a lawsuit against the company and its owner.

Marshall and Phillip Cabe had recently graduated from Cameron University in Oklahoma, and were on Kauai visiting their father.

The skydiving trip with D&J Air Adventures was a graduation present from him.

Their Cessna crashed and burned shortly after take-off from Port Allen airport in Hanapepe.

“He was expecting to watch his sons do the skydiving. Before they got that high, the engine failed, the plane crashed, and Mike was having to go to the burning Cessna 182 and try to pull his two sons out and give them CPR to try to keep them alive,” said attorney Rick Fried. “You can’t imagine what he went through having seen that. It was just horrific.”

The lawsuit seeks unspecified damages.

Two skydiving instructors and a pilot also died in the crash. The company has not commented on the lawsuit.

The National Transportation Safety Board released a preliminary report in June but has yet to file a full report.

Fried says he filed the lawsuit so the brothers’ parents can find out why the plane’s engine failed.
