Airworthiness Directive 2025-20-03
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of corrosion on one or more of the eight lower fitting assemblies and adjacent lavatory components on certain lavatories. This AD requires a detailed inspection of the lower fitting assemblies and the centerline partition threshold of the lavatories for corrosion, recording on the modification record placard, and applicable on-condition actions. This AD also requires revising the existing maintenance program to incorporate a detailed inspection of the lavatory vertical side forward fittings for corrosion or damage. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2025-20-03 applies to
Applies to airplanes as identified in Boeing Special Attention Requirements Bulletin B787-81205-SB250302-00 RB, Issue 001, dated August 21, 2024, except for airplanes identified as Group 3, Configuration 1; and Group 4, Configuration 3 airplanes.
Whether AD 2025-20-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
