Boeing 737-377, G-CELS
During pre-flight preparations smoke was seen coming from the overhead bin over seat row 1 D, E, F. The smoke was caused by arcing across the pins of the redundant No 2 Galley electrical connector. Tests confirmed that the connector remained powered despite the No 2 Galley CB being pulled and collared. A previous inspection had identified this issue, but the operator’s maintenance systems allowed the task to be closed prior to completion of the rectification work. The operator has changed the systems used to control such inspections to ensure that additional work must be completed before the inspection is closed. Any aircraft which may have been similarly affected, have been reinspected.
