THIS DOCUMENT IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH 1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS DOCUMENT TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS DOCUMENT TO THE NEW OWNER.
CONCURRENT REQUIREMENTS None.
BACKGROUND Accomplishment of this service bulletin will prevent the Captain's and First Officer's rudder pedals from operating incorrectly because of any protruding screw in the rudder pedal heel rest cover assembly. If this Service Bulletin is not accomplished, this condition could restrict rudder pedal motion and differential braking during takeoff or landing potentially leading to a high speed runway excursion.
A pilot from an operator reported that a flight was aborted during takeoff because the rudder pedals were not operating correctly. The airplane was returned to gate safely with normal tiller operation. The operator did further investigation, and found a protruding screw at the outboard edge of the Captain's rudder pedal heel rest cover assembly adjacent to the rudder pedal. Boeing has implemented a process of monitoring the screw installation starting at Line Number 3556 to ensure conformance to engineering requirements.
This service bulletin gives instructions to do a one-time torque check of the Captain's and First Officer's rudder pedal heel rest cover assembly screw locations adjacent to the rudder pedals.

If the torque requirement at all screw locations is correct, no more work is necessary. If any screw does not hold a torque or is not fully seated then replace the screw and nutplate. Do an operational check of the rudder pedals to make sure that motion is not restricted.
