Applicability*9
This AD applies to The Boeing Company Model 787-8 airplanes, certificated in any category, as identified in Boeing Service Bulletin B787-81205-SB530025-00, Issue 002, dated June 2, 2016 (“B787-81205-SB530025-00 Issue 002”).
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 12 months after the effective date of this AD: Change the configuration of the grounding jumpers connecting the ECS brackets and CRN straps, including measuring the bond resistance and doing all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of B787-81205-SB530025-00 Issue 002. Do all applicable related investigative and corrective actions before further flight.
Unsafe condition
This AD was prompted by a report that the grounding jumpers between the environmental control system (ECS) bracket and the current return network (CRN) straps near passenger 1 left and 1 right entry doors were not bonded correctly during manufacturing. We are issuing this AD to prevent an incorrectly bonded jumper between the ECS bracket and the CRN strap, which does not provide proper grounding to the door frames at doors 1 left and 1 right. If a fault occurs, an electrical shock hazard can exist and could result in serious or fatal injury to passengers and flight crew.
Affected ADs
None.
