Valujet flight 592

Closed - Acceptable Action Issued: FAA A Evaluate and support appropriate research, including the National Aeronautics and Space Administration research program, to develop technologies and methods for enhancing passenger respiratory protection from toxic atmospheres that result from in-flight and post-crash fires involving transport-category airplanes. FAA A Require airplane manufacturers to amend company maintenance manuals for airplanes that use chemical oxygen generators to indicate that generators that have exceeded their service life should not be transported unless they have been actuated and their oxidizer core has been depleted.

Another passenger, Tabitha Leonard, of Cloverdale, Indianadied a week before her 13th birthday on May 18, As a result, one of the episodes aired in the season features some of the first calls and the initial investigations into the accident.

He said in an interview that he wondered how he would investigate the incident since, through the aerial views on television, he saw no visible wreckage. The cargo compartment's fire suppression created a no-air recycling environment, so a standard fire would have simply run out of air and burned itself out.

However, the NTSB determined that just before takeoff, expired chemical oxygen generators were placed in the cargo compartment in five boxes marked COMAT Company-owned material by ValuJet's maintenance contractor, SabreTech, in contravention of FAA regulations forbidding the transport of hazardous materials in aircraft cargo holds.

Failure to cover the firing pins for the generators with the prescribed plastic caps made an accidental activation much more likely. As the Seconds From Disaster episode about the crash explains, rather than fitting firing pins on the canisters, the SabreTech workers just duct taped the cords around the cans, or cut them, and used tape to stick the ends down.

It is also possible that the cylindrical, tennis ball can-sized generators were loaded onboard in the mistaken belief that they were just canisters. SabreTech employees indicated on the cargo manifest that the "canisters" were empty, when in fact they were not.

Chemical oxygen generators, when activated, produce oxygen. As a byproduct of the exothermic chemical reaction, they also produce a great quantity of heat.

These two together were sufficient not only to start an accidental fire, but also produce the extra oxygen needed to keep the fire burning, made much worse by the presence of combustible aircraft wheels in the hold. NTSB investigators theorized that when the plane experienced a slight jolt while taxiing on the runway, an oxygen canister activated, producing oxygen and heat.

The oxygen from the generators fed the resulting fire in the cargo hold. A pop and jolt heard on the cockpit voice recording and correlated with a brief and dramatic spike in the altimeter reading in the flight data recording were attributed to the sudden cabin pressure change caused by a semi-inflated aircraft wheel in the cargo hold exploding in the fire.

A cargo hold fire caused by hazardous materials started, but the crew landed the aircraft safely. SabreTech's maintenance supervisor, Daniel Gonzalez, and two mechanics who worked on the plane, Eugene Florence and Mauro Valenzuela, were charged with conspiracy and making false statements.

Gonzalez and Florence were acquitted on all charges, while Valenzuela failed to appear and is currently missing. In so doing, the panel concluded that federal law at the time of the crash could not support a conviction for mishandling hazardous materials and that the government did not prove that SabreTech formed an intent to cause harm.

Just before the federal trial, a Florida grand jury indicted SabreTech on counts of manslaughter and counts of third-degree murder ; one for each person who died in the crash. SabreTech was the first American aviation company to be criminally prosecuted for its role in an American airline crash.

The company, a subsidiary of St. Louis -based Sabreliner Corporation, went out of business in It was allowed to resume flying again on September 30, but never recovered from the crash. Init merged with AirTran Airways. The ValuJet name was so tarnished by this time that it decided to take the AirTran name.

Many families of the Flight victims were outraged that ValuJet was not prosecuted, given ValuJet's poor safety record.

ValuJet had a higher accident rate than the 10 largest airlines, leading the FAA to take the unprecedented step of barring it from buying more planes or adding more cities without permission. The victims' families also point to statements made by ValuJet officials immediately after the crash that appeared to indicate ValuJet knew the generators were on the plane, and in fact had ordered them returned to Atlanta rather than properly disposed.ValuJet Flight was a flight that crashed on May 11, en route from Miami International Airport in Miami, Florida, United States, to William B.

Relatives of the people killed when ValuJet Flight caught fire and plunged into Florida's Everglades met and boarded airboats together on the 20th anniversary of the crash in The oxygen generators in Flight 's forward cargo hold came from three MDs, a more modern kind of twin jet, which ValuJet had recently bought and was having refurbished at a hangar across the.

This was the worst aviation accident in Florida and happened on May 11th, The plane crashed into the Florida Everglades. There were no survivors. The aircraft took off from Dallas-Fort Worth at in the morning.

It was bound for Miami and there was a scheduled stop in Atlanta. Everything.
