Southwest Captain Reduced Power Before NYC Crash Landing

July 22 (Bloomberg) -- A Southwest Airlines Co. jet's nose gear collapsed as it landed at LaGuardia Airport in New York, the Federal Aviation Administration said. No one on the Boeing Co. 737 or on the ground was injured, the FAA said in a statement. Flight 345 from Nashville, Tennessee, reported possible front landing gear issues before touching down at 5:45 p.m. New York time, the FAA said. (Source: Bloomberg)



The captain of a Southwest Airlines Co. (LUV) plane that skidded on its belly at New York’s LaGuardia Airport in July 2013 wrested control from the co-pilot and reduced power shortly before the landing, new documents show.


“I got it,” the captain said as she took over the controls four seconds before the plane made an unusual nose-down landing instead of settling onto the main wheels beneath the wings, according to a transcript of the cockpit conversation made public today by the National Transportation Safety Board.


The front landing gear collapsed under the weight, causing minor injuries to nine people, significantly damaging the plane and forcing LaGuardia Airport to shut down that day. The captain may not have followed airline procedures when she took the controls and at other times during the flight, according to the NTSB, which didn’t draw a definitive conclusion today.


“We continue to cooperate with the NTSB and look forward to the final report,” Brandy King, a spokeswoman for Dallas-based Southwest Airlines, said today. She declined to comment further because the NTSB investigation remains open.


The captain was fired after the accident, Southwest said Oct. 2, 2013. A spokeswoman for the airline, Linda Rutherford, declined at the time to specify why the airline took that action. The firing was upheld after an appeal, King said today. The co-pilot was ordered to take additional training.

Southwest Procedures


The documents released include a transcript from the cockpit recorder, photos of damage to the airplane and runway as well as statements from airport ground controllers.


Under Southwest’s flight rules, the pilots should have aborted their landing at LaGuardia because they hadn’t properly set the movable panels on the wings known as flaps as they descended below 1,000 feet (305 meters) altitude, according to the documents.


A split second before hitting the runway, the captain inhaled and uttered an unspecified expletive, according to the NTSB’s transcript.


The plane skidded down the runway for about 18 seconds. “Oh my god,” the captain said.


The incident, in which the plane wasn’t properly set up and stabilized for landing, falls into a category of accidents that has received increased attention from safety advocates, including the Alexandria, Virginia-based Flight Safety Foundation.


Risk Factor


The New York crash, along with the 2013 crash of an Asiana Airlines Inc. (020560) plane in San Francisco, may have been prevented if pilots had opted to abort their landings when it became clear that everything wasn’t in order, according to NTSB documents.


Crashes that occur during approach or touchdown are the world’s leading category of aviation mishaps and deaths, according to data compiled by Chicago-based manufacturer Boeing Co. (BA) The biggest risk factor for such accidents is failing to approach a runway at the proper speed, altitude and heading, known as an unstabilized approach.


The Southwest plane, a Boeing 737-700, was being flown by the co-pilot, a former U.S. Air Force pilot who was 44 at the time of the accident, according to the NTSB. He had about 5,200 flight hours.


The captain, who was 49 and had more than 12,000 hours, told investigators she believed the plane was too high for the landing and she took over because the co-pilot wasn’t reacting to her guidance.


Cutting Throttles


“She said she believed that if she did not act, the airplane would have continued to float past the touchdown zone,” the NTSB wrote in a report summarizing the pilot actions.


The co-pilot told investigators the captain put her hand on his hand as he was controlling the throttles and reduced the power shortly before reaching the runway. Only after that did she announce that she was taking control of the landing, he told investigators.


To prevent confusion during a switch in cockpit control, Southwest and other airlines require pilots to announce their intent to alter the throttles or any flight system before doing so.


The reduction in power combined with a failure to keep the nose tilted slightly upward led the plane to touch down on the front landing gear, according to an analysis by Boeing released by NTSB.


From late 2009 through early 2010, “a few” other pilots had complained to Southwest management about the captain, according to another report released by NTSB. One said she had a “harsh approach.” Another said she didn’t do a good job of soliciting input from co-pilots.


The captain received additional training in leadership and cockpit communication in February 2010 and the airline received no additional complaints afterward, according to the NTSB.
