ValuJet outsourced maintenance and shipped live oxygen generators as cargo — 110 died
Flight 592 caught fire and crashed in May 1996, killing all 110 aboard. Oxygen generators in the hold were loaded without safety caps by an outside contractor.
ValuJet · 1996-05-11
What happened
ValuJet was founded in 1993 and grew from 2 planes to 52 in three years by outsourcing maintenance to contractors. It was the fastest airline in US history to turn a profit, earning $21 million in 1994. But its accident rate was 14 times that of legacy airlines, and the FAA had flagged it for 'immediate re-certification' months before the crash — a memo that was 'lost in the maze' at the agency.
On 11 May 1996, ValuJet Flight 592, a DC-9 flying from Miami to Atlanta, crashed into the Everglades 10 minutes after takeoff. All 110 people on board died. The NTSB found the fire was caused by 144 expired chemical oxygen generators that SabreTech, a maintenance contractor, had illegally stowed in the cargo hold without safety caps. The fire melted the flight control cables, and the crew lost control.
The FAA grounded ValuJet entirely on 11 June 1996. It resumed flying on 26 September with only 15 jets, down from 52. The crash cost the company $55 million in losses in five months. In July 1997, ValuJet bought AirTran Airways, adopted the AirTran name to shed its reputation, and slowly disappeared into Southwest Airlines' 2011 acquisition.
Why it happened
- ValuJet outsourced maintenance to contractors like SabreTech without proper oversight. SabreTech loaded 144 expired oxygen generators into the cargo hold without safety caps, causing a fatal fire.
- The FAA had flagged ValuJet for 'immediate re-certification' months before the crash, but the memo was lost. By the time the agency acted, 110 people had already died.
- ValuJet's accident rate was 14 times that of legacy airlines, with 129 emergency landings in two years. The company prioritised growth over safety at every turn.
The lesson
An airline that outsources its safety along with its maintenance is not a low-cost carrier — it is a gamble. ValuJet's 14x accident rate was a warning that 110 people paid for.
