The Army has declared as deceased the final two missing members of a UH-60 Black Hawk that crashed Aug. 15 during night training off Kaena Point.

The 25th Infantry Division said Thursday the Army changed the status of Chief Warrant Officer 3 Brian M. Woeber and Chief Warrant Officer 2 Stephen T. Cantrell from “duty status — whereabouts unknown” to deceased after the Army adjutant general, Brig. Gen. James T. Iacocca, approved the results of a 25th Division administrative investigation into their status.

Woeber, 41, whose home of record was Decatur, Ala., entered active-duty military service in September 2003. Cantrell, 32, from Wichita Falls, Texas, entered active-duty military service in September 2007. Both were Black Hawk helicopter pilots assigned to Company A, 2nd Battalion, 25th Aviation Regiment, 25th Combat Aviation Brigade, 25th Infantry Division.

The 25th Division said it conducted an administrative investigation to determine the changed status “after extensive search and rescue efforts by the Army, Coast Guard, Navy and multiple local and state agencies were unsuccessful in locating the soldiers.”

All five crew members have now been declared deceased. The Armed Forces Medical Examiner previously made the determination for 1st Lt. Kathryn M. Bailey, 26; Staff Sgt. Abigail R. Milam, 33; and Sgt. Michael L. Nelson, 30, after trace remains discovered among floating debris were matched to their DNA.

The Black Hawk was on a routine nighttime training mission flying some distance behind another helicopter when it disappeared without a mayday call. It was reported missing at about 9:30 p.m. Floating pieces of the fuselage and four flight crew helmets were subsequently located.

The Army said its goal is the recovery of the crew and helicopter wreckage. The Navy’s Mobile and Dive Salvage Unit 1 has been using an unmanned underwater vehicle to sonar-map the ocean floor and possible wreckage and a remotely operated vehicle to take imagery if needed.

“They have located small portions of the aircraft and some other things, but I’m not going to go into specifics about what those are,” Lt. Col. Curt Kellogg, a 25th Division spokesman, said by phone. “They have the assets lined up locally that if they need to get (divers) in the water quickly, they can do so within a day or two, with a long-term plan to get a salvage ship here.”

That could be a contract vessel or Army watercraft, Kellogg said.

“Recovery and salvage efforts related to this incident are currently underway and are being supported by the U.S. Navy, the U.S. Coast Guard, and the 25th Infantry Division,” the Army said in a release. “There is no timetable for completion of these operations. The circumstances of this incident are currently under investigation.”

The search had been focused in water more than 150 feet deep roughly a mile offshore northwest and west of Kaena Point. The search has extended into water shallower and deeper than that and has ranged 2 to 4 miles offshore, Kellogg said.
