Investigators to Begin Underwater Search for Downed Hawaii Jet’s Black Boxes

By Alan Levin

·     Two pilots who survived ocean ditching to be interviewed

·      Investigators want to find why 737 lost power after takeoff

U.S. investigators plan to begin scanning the sea bed off Hawaii on Monday in search of the wreckage of a Boeing Co. 737-200 that went down after losing power in both its engines.

Special sonar devices that can map the sea bed will be used to locate critical wreckage and the jet’s two crash-proof recorders, the National Transportation Safety Board said in a release.

“That information will be used to determine how and when the recorders could be recovered and then how and if the airplane will be salvaged,” the NTSB said.

Investigators are also scheduling interviews with Transair Flight 810’s two pilots, who survived after ditching the plane early Friday, as well as with air traffic controllers and the small cargo operator’s maintenance workers. The company is branded as Transair and operated by Rhoades Aviation Inc.

The 46-year-old plane went into the water about 11 minutes after taking off from Daniel K. Inouye International Airport in Honolulu about 1:30 a.m. local time on July 2. After the plane lost one engine, pilots attempted to return for a landing. But a pilot radioed that the second engine was also failing.

So-called black box recorders on the plane should capture the pilots’ conversation in the cockpit and track the route and other data from the flight.

 

 

 

 

 

 

 

NTSB to interview pilots, survey site of ditched 737 cargo plane off Hawaii coast

 

·     The NTSB plans to use sonar imaging to determine when and how the voice-and-date recorders can be recovered

·     The pilots of Transair Flight 810 reported engine trouble and attempted to return to Honolulu.

Both pilots were rescued, officials said.

National Transportation Safety Board investigators plan to use sonar imaging on Monday to try to locate a Boeing 737-200 cargo jet that ditched off the coast of Hawaii last week.

Transair Flight 810 made an emergency landing in the ocean off the coast of Oahu around 1:30 a.m. local time on Friday. The cargo plane’s pilots reported engine trouble shortly after leaving Honolulu. Both of the pilots were rescued.

The NTSB said it must first find the exact location of the 46-year-old plane before the cockpit voice and data recorders can be recovered.

“Investigators plan to use side scan sonar Monday to survey the debris field, the condition of the airplane and its location, including how far beneath the surface the plane sank,” it said in a statement. “That information will be used to determine how and when the recorders could be recovered and then how and if the airplane will be salvaged.”

The NTSB said it is also scheduling interviews with the two pilots, air traffic controllers and maintenance workers at cargo airline Transair.

The agency said a small amount of floating debris was recovered and examined by NTSB. The exact cause or causes of the crash can take months to determine.

The carrier didn’t respond to a request for comment.

One of the pilots told an air traffic controller that the plane lost an engine and that there was a chance it was going to lose the other, according to audio posted to LiveATC.net.

The controller warned them that their altitude was low but another pilot responded that they couldn’t climb.

The NTSB said it met with parties to the investigation — the Federal Aviation Administration, the National Air Traffic Controllers Association, Boeing, Pratt & Whitney, which made the plane’s engines, and Rhodes Aviation — the aircraft’s operator, on Saturday.

Narrative:
Transair flight 810, a Boeing 737-200C cargo plane, ditched in the waters off Honolulu, Hawaii. Both pilots were rescued.
The aircraft took off from runway 08R at Honolulu-Daniel K. Inouye International Airport at 01:33 hours local time. After takeoff the flight reported engine issues and the flight crew initiated a turn back to the airport, receiving vectors from ATC.
The flight reported failure of engine no.1 and difficulty in maintaining altitude. Unable to see the airport, the flight crew was issued heading directions from ATC. After ATC got a low altitude alert from the flight, the controller suggested diverting to Kalaeloa Airport, which was closer by. Unable to reach the airport, the aircraft was ditched at 01:45 hours.
A U.S. Coast Guard MH-65 Dolphin helicopter was able to rescue one of the people on board while the Honolulu Fire Department rescue boat recovered the other.
