BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.

CONCURRENT REQUIREMENTS

None.

BACKGROUND

This service bulletin gives instructions to install new Operational Program Software (OPS) into the Flight Control

Computers (FCCs). This new software includes a Takeoff Engage Inhibit feature. This feature prevents an

autopilot engagement when the airplane is on the ground with the flaps down. If this change is not done, the

autopilot could be engaged while the airplane is on the ground. The autopilot could then cause stabilizer trim

beyond the greenband limits, which could lead to a high speed rejected takeoff condition.

Boeing Service Related Problem (SRP) 767-SRP-22-0035 is related to this service bulletin.

The related Boeing Service bulletin is SB 767-22-0143.
