How Did Crew Scheduling Change After Asiana Flight 214

Asiana Airlines Flying 214 originated in Seoul, Republic of korea, destined for San Francisco. Here's what nosotros know about Saturday's crash landing.

earlier impact

The flying descended faster and more than steeply than previous flights on this same road.

The graph to the right, showing approximate distance data from FlightAware.com, displays approach data from the same flight the day before the crash and Saturday's approach, which indicates a steeper decline in altitude.

Note: NTSB investigators have plant nothing to corroborate online flight tracking records, such as the ones shown here, that Saturday's Flight 214 descended from cruising altitude much more steeply and speedily than previous Asiana flights on the same route. The National Transportation Safety Lath says it found no "abnormally steep descent data."

seven seconds
before impact

A preliminary readout from the flying data and cockpit voice recorders shows the aircraft was budgeted well below the target landing speed of 137 knots (157 mph).

At seven seconds earlier impact, the pilots are heard acknowledging the slow speed and attempted to spool upwards the engines to increase the aeroplane'due south speed.

4 seconds
before touch on

At four seconds, the plane's computer triggers a "stick-shaker" alert, indicating an impending aerodynamic stall. A stall occurs when in that location is non plenty airspeed to sustain lift to keep the aircraft in flight.

3 seconds
earlier impact

The flight information recorder shows the lowest recorded airspeed during the approach, at 103 knots (118 mph). At this time, the engine power was recorded at fifty% and increasing.

Ane of the coiffure members phone call out for a "go-around," an attempt to abort the landing. Both engines were producing power up to the fourth dimension of impact, according to investigators.

1.5 seconds
before impact

At 1.v seconds before touch on, a second call for a go-around is fabricated, this time by some other member of the crew.

Passengers on board depict hearing the engines spooling up and the nose tilting upwardly just before impact.

Impact

The flying information recorder indicated an airspeed of 106 knots (122 mph) at the fourth dimension of the crash, well below the targeted 137 knots.

According to investigators, the plane's main landing gear struck the rock body of water wall well before the kickoff of the runway, followed by the tail department of the aircraft.

NTSB investigators discovered the lower portion of the tail cone in the rocks of the body of water wall, likewise as a significant piece of the tail establish in the water. Boosted parts were reportedly visible in the h2o at low tide.

Watch exclusive video of the crash landing

Three flight attendants in the rear of the plane were ejected from the aircraft during impact, and were institute injured beside the rails.

The debris field runs from the water, slightly right of the paved threshold and rail center, all the fashion to the stopped aircraft fuselage. Pieces of the cabin were discovered very early on on in the debris field, including shipping parts, galley materials, newspapers, and magazines, according to investigators.

One of the eight doors on the aircraft was separated during the impact. The remaining seven doors were found attached to the fuselage.

The rest of the Boeing 777's tail department, including its vertical and horizontal stabilizers, was found about the finish of the paved threshold, just before the start of the rail. Full loss of the tail section would take made the aircraft extremely difficult to control.

The fuselage came to residual off the left side of the runway, and information technology'due south pointed toward the right.

The correct engine is detached from the fly and wedged against the right side of the fuselage, communicable fire due to an oil tank rupture. The left engine detached from the fly during the crash and is a considerable distance from the fuselage in a grassy area to the right of Runway 28L.

Later touch on

Most of the fire harm to the aircraft occurred later on the Boeing 777 came to a stop on its belly, but most of the passengers were able to evacuate before fire breached the passenger cabin. Passengers described the motel interior as heavily damaged, with overhead bins dropping and two life raft/escape slides inflating inside the aircraft, trapping two flight attendants, whom passengers and other crew members helped gratuitous.

The coroner says one of the two passengers killed appears to accept been run over past an emergency vehicle, but final cause of decease has not been determined. Asiana has identified the 2 deceased as Ye Mengyuan and Wang Linjia of Cathay. Both were 16.

The crew

At that place were three pilots in the cockpit at the time of the crash, according to crew interviews conducted by investigators.

The "flying pilot" -- as NTSB chairman Deborah Hersman referred to him -- was a veteran airplane pilot with near x,000 hours of total flying time, though he was in his "initial operating experience" in flight the Boeing 777. He had flown 10 legs and had almost 35 hours of flight time with the 777, which put him virtually halfway through the required training of xx legs and 60 flight hours, when the airplane went down, Hersman said.

Sitting next to the "flying pilot" in the right seat was an teacher airplane pilot -- another veteran captain with an estimated thirteen,000 hours of total flight time. The teacher airplane pilot told investigators he was the pilot in control at the time of the crash. This was the first time he and the pilot he was instructing had flown together, and the offset time he had acted every bit an teacher pilot.

In the cockpit jumpseat was a relief beginning officer with an estimated 900 - 1,000 hours of flying time on the 777.

A fourth pilot, the relief captain, was seated in the passenger cabin during the crash. The relief helm and relief first officer had flown the aircraft during the prowl portion of the trans-Pacific flying, allowing the flying airplane pilot and instructor pilot to rest and consume during the flying.

Of the pilots in the cockpit, but the relief first officer was injured -- neither of the ii pilots at the controls were admitted to the hospital. The pilots did non undergo drug or alcohol testing afterwards Sat's crash landing, Hersman said. The United states does not have "oversight" of foreign-based operators or their crews.

The Boeing 777-200ER

The get-go Boeing 777 went into service in 1995. It has a maximum range of vii,725 nautical miles, with a typical cruise speed of almost 570 mph.

Asiana Airlines took delivery of the shipping involved in Sat's crash landing in 2006. Information technology is 1 of 12 Boeing 777 aircraft in Asiana'south fleet.

Only i other incident involving a Boeing 777 resulted in a complete loss: British Airways Flying 38 from Beijing landed short of the rail at London's Heathrow airport in January 2008 later engine trouble soon before landing, blamed on fuel icing later a lengthy flight over Siberia. No one died in that incident. Design changes were made to the 777 to minimize fuel icing when flying routes over extremely cold regions.
