NTSB narrative
THE BOEING 737 WAS ON LANDING ROLL WHEN A DOOR IN THE AFT GALLEY OPENED. A LIQUOR KIT ROLLED OUT TOWARD AN AFT FACING FLIGHT ATTENDANT WHO FENDED OFF THE KIT WITH HER LEFT HAND. HER HAND BENT REARWARD AND THE FLIGHT ATTENDANT RECEIVED A BROKEN WRIST. BOTH FLIGHT ATTENDANTS SEATED IN THE REAR OF THE AIRPLANE SAID THEY BELIEVED THE DOOR WAS LOCKED PRIOR TO LANDING. AFTER LANDING THE FLIGHT ATTENDANTS WERE ABLE TO OPEN THE DOOR AGAIN BY HAND AFTER IT WAS LOCKED. MAINTENANCE PERSONNEL WERE UNABLE TO DUPLICATE THE FAILURE; HOWEVER, THE LATCHES WERE REPLACED AS A PRECAUTION.
Probable cause
A LATCH FAILURE ON A DOOR IN THE AFT GALLEY WHICH ALLOWED A LIQUOR KIT TO ROLL FORWARD.

Source notes (4)
- 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, 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.
