Two men died Saturday after a single-engine Cessna Ector 305A crashed about 200 yards from the Dillingham Airfield, the site of a horrendous skydiving crash in June that killed all 11 on board.

The Cessna, which is owned by the Honolulu Soaring Club, crashed under unknown circumstances soon after taking off at about 9:15 a.m., authorities said.

The plane came to rest upside down, killing a man in his 60s and the critically injuring another man, 78, who was treated by paramedics at the scene and taken to a hospital where he died.

Dillingham Airfield, which is operated by the state Department of Transportation under a lease with the U.S. Army, is scheduled to be transferred back to Army control on July 1.

“Our hearts are with those affected by today’s tragic accident,” U.S. Sen. Brian Schatz said in a statement following the crash. “It has become clear that Dillingham Airfield cannot continue to operate safely. Our obligation is to keep people safe, and the only way to do that is to keep the airfield closed. I urge the FAA and HDOT to shut down the airfield until they can guarantee safety of operations at Dillingham.”

In June, 11 people died when their skydiving plane crashed at Dillingham Airfield, the deadliest civilian aircraft accident in the U.S. since a 2011 Reno Air Show crash that killed the pilot and 10 passengers. National Transportation Safety Board investigators said that plane apparently flipped and burned shortly after takeoff.

Following today’s crash, Mayor Kirk Caldwell issued a statement on Twitter that said, “I’m deeply saddened to hear the news of two people losing their lives in today’s crash. My heart goes out to the family and friends of the victims. Thank you to all the first responders on scene today. We are working with ME’s office to make sure family members are notified.”

The single-engine Cessna 305A that crashed today came to rest upside down, said Federal Aviation Administration spokesman Ian Gregor.

“The FAA and NTSB will investigate,” Gregor said in a statement. “The NTSB is the lead agency and it typically takes the NTSB a year or more to determine a probable cause of an accident. Neither the FAA nor NTSB identifies people involved in aircraft accidents.”

The information was preliminary and subject to change, Gregor told the Star-Advertiser.

UPDATE: 2:27 p.m.

The single-engine Cessna Ector 305A crashed approximately 200 yards away from the Dillingham Airfield runway earlier today.

Over two dozen emergency personnel were still investigating the scene of the crash, where two men in their 60s were killed just before 9:30 a.m. today.

Honolulu Soaring Club, the owner of the plane has been notified, according to DOT spokesman Timothy Sakahara.

“This is obviously a tragic incident, and it certainly just happened,” said Sakahara. “So the focus right now is in the incident itself, focusing on the response and recovery.”

Federal investigators will be at the scene tomorrow around 8 a.m., he said.
