## Discrepancy

CABIN SEATS 3AB, 3CD, 17ABC FAILED O2 MASK RELEASE CHECK.   [SUP 05-29-07]   ADJUSTED THE OXYGEN CONTAINER DOOR SPACERS AND REPLACED THE RELEASE SOLENOIDS AS A PRECAUTIONARY MEASURE. AT SEATS 17ABC, FOUND THE ELECTRICAL CONNECTOR DISCONNECTED. RECONNECTED & PERFORMED DROP TEST. TESTS OKAY.
