## Probable cause

A LATCH FAILURE ON A DOOR IN THE AFT GALLEY WHICH ALLOWED A LIQUOR KIT TO ROLL FORWARD.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, landing - roll
  - misc eqpt/furnishings,storage bins/racks - failure,total (cause)

## Analysis

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.
