A Beechcraft Sundowner that made an emergency ocean landing off Makaha Beach Park on Monday should be pulled out of 15 to 20 feet of water today, when a senior aviation accident investigator from the National Transportation Safety Board also hopes to interview the 56-year-old male pilot.

The owner’s insurance company is responsible for recovering the Beechcraft and storing it in a secure location for federal investigators, said Josh Cawthra, who is investigating the emergency landing.

“At this point we’re trying to figure out what happened and get it out of the water,” said Cawthra, who is based in Sacramento, Calif.

The Beechcraft had been heading from Lihue to Honolulu Airport when it hit the water at about 11:20 a.m., about 50 yards from shore.

The pilot and a 52-year-old female passenger were treated for chest abrasions and taken in stable condition to a hospital.

The plane is co-owned by Eric and Leslie Ann Kawamoto of Honolulu. Leslie Kawamoto declined Tuesday to be interviewed by the Honolulu Star-Advertiser.

Federal Aviation Administration investigators already have spoken to the pilot, said Cawthra, who is planning his own interview today.

It could take six months to a year to determine a probable cause of the crash, he said.
