NTSB narrative
While preparing coffee service in the aft galley, the C flight attendant (FA) observed the coffee maker emitting an unusual noise and coffee was pooling on the burner. The FA lifted the potlocking lever on the coffee pot and hot coffee and coffee grounds erupted onto her face, neck, and chest. The flight diverted and landed at Nashville International Airport, Nashville, Tennessee where medical personnel met the flight at the gate. The FA was transported to the hospital and diagnosed with second-degree burns.
In January of 2013, the Federal Aviation Administration issued Safety Alert For Operators (SAFO) 13001, which addressed reported cases of coffee filter packages bursting in flight during coffee preparation, resulting in 1st and 2nd degree burns to flight attendants and bystanders. The SAFO encouraged air carriers and operators to add cautionary instructions and procedures to the Flight Attendant Manual (FAM) and training program, warning crew members of the dangers to personnel and equipment.
Probable cause
A buildup of pressure in the coffee filter package resulting in the release of hot coffee and grounds when the potlocking lever was raised, which resulted in 2nd degree burns.

Source notes (5)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates, damage. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 92a16c9881ec1bf475d996afd57010260136fb7f54ee172abc2ce72a4b36a8db; retrieved 2026-09-15T23:15:04.756Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: destination. Destination label misspells Fort Myers; KRSW is Southwest Florida International Airport, Fort Myers, Florida.
