Reason

This bulletin provides information for flight crews regarding engine out FMC anomaly after takeoff.

Information in this bulletin is recommended by The Boeing Company, but may not be FAA approved at the time of writing. In the event of conflict with the FAA approved Airplane Flight Manual (AFM), the AFM shall supersede. The Boeing Company regards the information or procedures described herein as having a direct or indirect bearing on the safe operation of this model airplane.

Background Information

On flights such as training flights where multiple takeoffs and landings occur, the Engine Out Standard Instrument Departure (E/O SID) will not automatically load with loss of an engine after takeoff. The E/O SID can still be manually selected by the crew.

This anomaly appears on airplanes with the PEGASUS FMC installed. The PEGASUS FMC can be identified by a VNAV Mode Key on the CDU.

Operating Instructions

Ensure the departure runway is re-selected prior to each takeoff if the engines have not been shutdown.

Administrative Information (Extract)

This anomaly will be corrected by Boeing Service Bulletin 757-34-0181 scheduled to be available April 1, 1999.
