Models named: 787-8, 787-9. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to The Boeing Company Model 787-8 and 787-9 airplanes, certificated in any category, as identified in Boeing Service Bulletin B787-81205-SB270030-00, Issue 001, dated October 22, 2015.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 40 months after the effective date of this AD, replace the EMAs with new EMAs, in accordance with the Accomplishment Instructions of Boeing Service Bulletin B787-81205-SB270030-00, Issue 001, dated October 22, 2015.

Unsafe condition

This AD was prompted by wire harness chafing on the electro-mechanical actuators (EMAs) for certain spoilers due to insufficient separation with adjacent structure. We are issuing this AD to prevent chafing and consequent wire damage that could result in a potential source of ignition in the flammable leakage zone and a consequent fire or explosion.

Affected ADs

None.
