Models named: 787-8 series. 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 series airplanes, certificated in any category, as identified in the service information specified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD. (1) Boeing Alert Service Bulletin B787-81205-SB380009-00, Issue 002, dated December 9, 2015. (2) Boeing Alert Service Bulletin B787-81205-SB530029-00, Issue 002, dated January 26, 2016. (3) Boeing Alert Service Bulletin B787-81205-SB530031-00, Issue 002, dated March 16, 2016.

Compliance

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

Required actions

Within 24 months after the effective date of this AD: Replace the existing potable waterline couplings located above the forward and aft EE bays with new, improved couplings, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB380009-00, Issue 002, dated December 9, 2015. Before further flight after doing the replacement, do a potable water system leak test and repair any leaks found before further flight, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB380009-00, Issue 002, dated December 9, 2015.

Unsafe condition

This AD was prompted by reports of water leakage from the potable water system due to improperly installed waterline couplings, and water leaking into the electronics equipment (EE) bays from above the floor in the main cabin, resulting in water on the equipment in the EE bays. We are issuing this AD to prevent a water leak from an improperly installed potable water system coupling, or main cabin water source, which could cause the equipment in the EE bays to become wet, resulting in an electrical short and potential loss of system functions essential for safe flight.

Affected ADs

None.
