Commercial Airplanes 757 Service Bulletin ALERT SummaryNumber: 757-27A0157Original Issue: December 18, 2017 ATA System: 2760 SUBJECT: FLIGHT CONTROLS - Spoiler, Drag Devices and Variable Aerodynamic Fairings - New Spoiler Control Module Relay Wiring Change
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 make sure that the changes given in Boeing Service Bulletin 757-27A0152, that prevent the deployment of spoiler pairs 1 and 12 and 5 and 8 during landing operations, are deactivated. If the SB is not done it will leave the airplane at risk for a potential failure mode that can cause an uncommanded spoiler movement that can put the airplane into excessive lateral control resulting in loss of controllability of the airplane.
Boeing has received a report that a 757 operator that had accomplished Boeing Service Bulletin 757-27A0152, had experienced a momentary uncommanded spoiler movement when configuring the flaps just before landing.
Boeing Service Bulletin 757-27A0152 gives protection to reduce the chance of a Pilot Induced Oscillation (PIO) on airplanes when the pilot is trying to make quick flight maneuvers, such as the final phase of landings in strong wind conditions. However, subsequent investigation of Boeing Service Bulletin 757-27A0152 has identified a failure effect that could result in uncommanded spoiler movement that could lead to loss of controllability of the airplane.
This service bulletin gives instructions to deactivate the changes given in Boeing Service Bulletin 757-27A0152.
Boeing Service Related Problem (SRP) 757-SRP-27-0290 is related to this service bulletin.
Boeing Multi-Operator Message MOM-MOM-17-0685 is related to this service bulletin.
ACTION Group 1-3, Configuration 1:
Get access to the Electronic Equipment Bay (E/E Bay). Remove the E3-1 electronics shelf from the airplane if necessary. Make changes to wire bundle W1265. Install the E3-1 electronics shelf to the airplane, if removed, and do a test of the Spoiler/Speedbrake Control System. Close access.
