The FAA proposes to supersede Airworthiness Directive (AD) 2017-26-10 which applies to certain The Boeing Company Model 757 airplanes. AD 2017-26-10 requires deactivating the spoiler control module relays and capping and stowing the associated wiring on certain airplanes. Since the FAA issued AD 2017-26-10, Boeing has developed wiring changes for certain spoiler control modules (SCMs), which will improve the lateral handling qualities of the airplane during approach and landing. This proposed AD would require repetitive operational tests of the spoiler inhibit function. For certain airplanes, this proposed AD would require installing a new relay bracket assembly, making changes to the wire bundles for certain SCMs, installing new SCMs, measuring the clearance between a wire bundle and the top of the new relay bracket assembly, and applicable on-condition actions. For a certain other airplane, this proposed AD would require changing certain wire bundles. The FAA is proposing this AD to address the unsafe condition on these products.
