NTSB ID: CHI07MA310On September 28, 2007, at 1316 central daylight time, a McDonnell Douglas DC-9-82 (MD-82), N454AA, operated by American Airlines as flight 1400, executed an emergeny landing at Lambert-St Louis International Airport (STL), St. Louis, Missouri, after the flight crew received a left engine fire warning during departure climb from the airport. The airplane sustained minor damage. Visual meteorological conditions prevailed and an instrument flight rules flight plan was filed for the 14 CFR Part 121 scheduled domestic flight. After landing, the 2 flight crew, 3 flight attendants, and 138 passengers deplaned via airstairs and no occupant injuries were reported. The intended destination of the flight was Chicago O'Hare International Airport (ORD), Chicago, Illinois.
Upon receiving the left engine fire warning during climb, the flight crew discharged the aircraft engine fire bottles into the affected engine. During the visual return and single-engine approach to the airport, the nose landing gear did not extend. The flight crew then extended the nose landing gear using the emergency landing gear extension procedure. The airplane returned and then landed on runway 30L (11,019 feet by 200 feet, grooved concrete) and was met by STL Airport Rescue and Fire Fighting Vehicles.


Practicing an emergency, and actually having one are not the same beast.xsbank wrote:Really, normal engine fail with fire - practise 'til you were blue in the face, every 6 months in the sim. Just another event. Really. The gear added some stress, but they used the airstairs to get out...

Go back and read the report before you type garbage like that. The TSB investigation is most likely the closest we will get to the events for that flight.xsbank wrote:Swissair was a tragedy that nobody had ever encountered before. The crew made some incorrect decisions and there was a total loss.

Was that the days of harrison air, or, the goonie doing the run in/out of lovell cove / leo creek area ? Those are the only two I remember seeing parked in YWL with engines coming off.xsbank wrote: And yes, #2 engine fire in a DC-3, fortunately at top of climb. No simulator, rudimentary training and tons of avgas. Fire went out with the bottle, piston and cylinder sticking through the cowl, 20+ passengers, heavy snow/VOR into William's Lake.

By John Hughes and Mary Schlangenstein
April 7 (Bloomberg) -- April 7 (Bloomberg) -- Faulty maintenance caused an American Airlines engine fire that forced an emergency landing in St. Louis in 2007, a U.S. safety board concluded.
The pilots’ failure to complete a checklist prolonged the fire, and Americans’ shortcomings in detecting maintenance flaws contributed, the National Transportation Safety Board said today in Washington. Flight 1400’s emergency landing in St. Louis on Sept. 28, 2007, didn’t result in injuries.
The findings may add to questions about maintenance at AMR Corp.’s American, which was forced by regulators to ground planes last year for flawed inspections. Workers in the St. Louis incident used a tool to start the engine manually, a banned method often employed when a filter inside the component deteriorated and caused normal starts to fail, NTSB investigator Lorenda Ward said today at a hearing.
“Personnel did not follow company cleaning procedures for the air filter during regular maintenance checks,” Ward said. “As a result, the damage to the air filter went undetected.”
The St. Louis emergency occurred shortly after the plane took off for Chicago with 138 passengers and a crew of five. The safety board examined maintenance procedures as well as the actions of the pilots.
“We have participated with the NTSB in their investigation of the events of Flight 1400, and we will address their determinations after they present them publicly,” Tim Wagner, a spokesman for Fort Worth, Texas-based American, said yesterday.
Stranded Passengers
American, the world’s second-largest airline, was forced by the Federal Aviation Administration in March and April 2008 to ground its fleet of 300 Boeing MD-80s to inspect and correct wiring in wheel wells. More than 3,300 flights were canceled and 360,000 passengers stranded during five days, as American examined and fixed wiring bundles.
The carrier told the NTSB in January that the probable cause of the St. Louis emergency was the deterioration of a start-valve filter. That led to malfunctions that forced mechanics to manually start the engine, American said in its submission to the board.
American’s maintenance handbook prohibits crews from the type of manual start they used that day, and Boeing’s cautions against using a prying tool such as a screwdriver that can damage a valve. The NTSB found the valve in the 2007 incident “deformed” and “dented.”
Pilot Checklists
NTSB evidence also showed the pilots in the St. Louis incident failed to complete some cockpit procedures, including checklists for an engine fire, a one-engine landing and emergency landing.
The pilots union, the Allied Pilots Association, told the board in January it believes the evidence points to American’s repair processes not being followed, “clearly compromising the effectiveness of their maintenance reliability program.”
Boeing told the NTSB in January the probable cause was a start-valve failure and the engine being kept on high power for a minute after a fire warning in the cockpit.
The start valve in the engine was replaced six times in 12 days before the accident, according to the NTSB. American in its submission blamed the filter deterioration for “a series” of start-valve problems.
Those required mechanics to conduct manual starts, and the workers used tools rather than hand pressure because the valve becomes “painfully hot,” American told the board.
Manual Override
“Although it was not authorized by American, in order to make more reliable and less painful use of the manual-override pushbutton, mechanics sometimes used a lever,” American said.
In August, the NTSB proposed fines of as much as $7.1 million against American over allegations of deferred maintenance, drug and alcohol testing deficiencies, and inadequate lighting inspections. American disagreed with the FAA findings and said the proposed fines were “excessive.”
On March 30, the FAA began a comprehensive review of American’s safety and operations. The review was triggered in part by the MD-80 inspection lapses last year, said Alison Duquette, an FAA spokeswoman.
Similar evaluations have occurred at Southwest Airlines Co. and Continental Airlines Inc.
American is the second-biggest airline after Delta Air Lines Inc.
