2 Die as Asiana Cargo Plane Crashes Off South Korea

SEOUL, South Korea — An Asiana Airlines cargo plane crashed into waters off the southern coast of South Korea on Thursday after reporting a fire in its cargo compartments, government officials said.

A pilot seat, wing tip and other parts of the wreckage were recovered by maritime patrol boats about 70 miles west of Jeju, the southernmost island off South Korea, the Ministry of Land, Transport and Maritime Affairs said in a statement. The maritime police were searching the sea for the plane’s two-man crew — the pilot and co-pilot — whose fate remained unknown.

The Boeing 747-400F jet took off from the Incheon airport west of Seoul at 3:05 a.m. on Thursday, bound for Pudong, China. It was carrying 58 tons of electronic and machine parts, including batteries, paint and other chemicals considered inflammable, the ministry said. In its last communication with the Shanghai air traffic control center at 4:03 a.m., it reported a fire in its cargo, Kim Han-young, a senior ministry official in charges of air transport policy, said during a news briefing. The jet is believed to have crashed nine minutes later, as it turned around and was headed for an emergency landing in the Jeju airport, Mr. Kim said.

It was the worst accident for Asiana since one of its domestic passenger jets slammed into a hill in southwestern South Korea in 1993, killing 68 people.

The Boeing 747-400 entered service in 1988 and was the largest commercial aircraft in the skies until the Airbus A380 entered service in 2007. It is currently the most recent version of the 747 in service.

Boeing’s 747 family of aircraft has a strong safety record, with only 42 accidents since the jumbo jet was introduced in 1969, according to the Aviation Safety Network, which maintains a database of air accidents. The most recent involved a freighter version of the plane operated by UPS, which reported heavy smoke in the cockpit shortly after take-off from Dubai Airport in September 2010, killing the two pilots aboard. The cause of that crash remains under investigation, although the plane was known to have been carrying several shipments of lithium ion battery packs, which are considered hazardous material.

Two die as Boeing 747 cargo jet crashes off South Korea

Both pilots aboard a China-bound Boeing 747 cargo jet were killed when it crashed off South Korea after experiencing mechanical problems.

The plane, which was flying for South Korea's Asiana Airlines, came down off Jeju island in the very south of the country, local media report.

It had left Incheon en route to Pudong in China.

A South Korean coast guard boat found debris from the jet in waters about 107km (66 miles) west of Jeju city.

After taking off at 0305 (1800 GMT) the plane disappeared from radar at 0409 while trying to reach Jeju airport, the South Korean news agency Yonhap reports. The wreckage was spotted at 0640.

Both the pilot and co-pilot were killed.

Heavy rain has lashed South Korea this week, with landslides and floods killing dozens and causing havoc, but Asiana Airlines said it was unclear whether the weather had caused any problems for the plane.

The 747, nicknamed the Jumbo Jet, has been in service around the world for more than four decades, and is still in production.

Cockpit 'mismanagement' blamed in Asiana crash
AFP By Robert MacPherson
June 24, 2014 9:04 PM

Washington (AFP) - A mismanaged approach for landing in a highly automated cockpit was the probable cause of last July's crash of a South Korean airliner in San Francisco, US investigators said Tuesday.

Three young Chinese citizens died and 182 people suffered injuries when Asiana Flight 214 from Seoul clipped a sea wall with its landing gear, then crashed and burst into flames, in the first commercial airliner disaster in the United States since 2009.

"In this investigation, we have learned that pilots must understand and command automation, and not become over-reliant on it," said acting chairman Christopher Hart of the National Transportation Safety Board (NTSB).

"The pilot must always be the boss," added Hart, a licensed pilot himself, at the end of a day-long NTSB hearing that concluded the federal agency's probe into the July 6, 2013 disaster.

While the Boeing 777 was in the hands of "a seasoned flight crew with a good safety record, they misunderstood the automated systems at their command," Hart said.

The NTSB, which never explicitly assigns blame, refrained from explicitly accusing the Asiana crew of pilot error.

Instead, it cited a long and varied list of contributing factors, from the Boeing 777's automated throttle system to pilot fatigue and jet lag after an otherwise routine 10-1/2 hour trans-Pacific hop.

- Autopilot switched off -

Investigators testified that captain Lee Kang-Kuk, a seasoned Airbus A320 pilot transitioning to the bigger Boeing 777, cut the autopilot on final approach into San Francisco, where the instrument landing system was out of service on a clear sunny day.

Doing so put the auto-throttle on hold, meaning it would no longer automatically control airspeed, explained investigator-in-chief Bill English.

When the jet dipped below the correct glide path, Lee reacted by pulling the nose up -- but the auto-throttle, still on hold, failed to deliver an expected burst of engine power that would have enabled the airliner to make the runway.

"The Boeing 777 is one of the more sophisticated and automated aircraft in service," Hart said.

"But the more complex automation becomes, the more challenging it is to ensure that pilots adequately understand it," he added.

- 'Maximum use of automation' -

English said Asiana, established in 1988 as a rival to Korean Air, emphasized "maximum use of automation" by its pilots, including the use of autopilots at as low as 1,000 feet (330 meters) from the ground.

Without mentioning Lee by name, English said the captain lacked sufficient practice in hand-flying the airplane, without the help of instrumentation.

Lee flew into San Francisco with an instructor in the co-pilot's seat, Lee Jung-Min, who himself was freshly certified to train new 777 pilots. A first officer was in a jump seat.

While finding issues in the cockpit, the NTSB hailed the fact that 99 percent of the passengers and crew survived -- and that 98 percent "self-evacuated" from the burning wreckage.

Flight attendants had performed "admirably and bravely," said Hart, who stressed the role seat belts had played in saving lives.

Of the three fatalities, one was hit by an exit door, while the others -- hurled out of the aircraft on impact -- had been seen by other passengers not buckling their seat belts for landing.

Asiana meanwhile said the NTSB "has properly recognized the multiple factors that contributed to the accident, including the complexities of the auto-throttle and autopilot systems, which the agency found were inadequately described by Boeing in its training and operational manuals."

“We again express our great sorrow for the accident, the loss of life and the injuries sustained by the passengers and crew."

“The NTSB made four training recommendations to Asiana, all of which Asiana has already implemented," the airline added in its statement.

Boeing "respectfully" disagreed with the NTSB's suggestion that the complexity of its automated cockpits was a factor in the first fatal accident ever involving its 777 model, in service for two decades.

It said in a statement its auto-flight system had been used successfully for more than 200 million flight hours across several airplane models, and for more than 55 million safe landings.

"The evidence collected during this investigation demonstrates that all of the airplane's systems performed as designed," Boeing said.
