EASA AD US-2025-20-03
Equipment / Furnishings - Lower Fitting Assemblies and Centerline Partition Threshold of Lavatories - Inspection / Revision of Maintenance Program
Summary
The document titled "Equipment / Furnishings - Lower Fitting Assemblies and Centerline Partition Threshold of Lavatories - Inspection / Revision of Maintenance Program" is a Federal Aviation Administration (FAA) Airworthiness Directive (AD 2025-20-03) addressing certain Boeing 787-8, 787-9, and 787-10 airplanes. It mandates inspections for corrosion on lower fitting assemblies and lavatory components and requires updates to the maintenance program to include inspections of lavatory vertical side forward fittings. This AD aims to ensure continued airworthiness and safety of the affected Boeing 787 models.
What Changed
This new AD introduces a detailed inspection requirement for corrosion on the lower fitting assemblies and centerline partition thresholds of lavatories on specified Boeing 787 models. It also requires recording inspection results on modification record placards and revising maintenance programs to include inspections of lavatory vertical side forward fittings. Additionally, the AD excludes airplanes never equipped with Jamco family 95/96 lavatories from its applicability and sets specific compliance times for administrative actions.
Why It Matters
This AD is critical for aviation professionals because it addresses an unsafe condition related to corrosion in lavatory fittings that could affect aircraft safety. Operators and maintenance organizations must comply to prevent potential structural or functional failures in lavatory assemblies. The directive ensures that maintenance programs are updated to detect and mitigate corrosion risks, thereby maintaining regulatory compliance and operational safety.
What To Do
Affected operators must perform detailed inspections for corrosion on the specified lavatory fittings by November 6, 2025, and record findings on modification placards. They must also revise their maintenance programs to include inspections of lavatory vertical side forward fittings. Administrative actions such as placard recording and maintenance plan revisions must be completed within 90 days after the initial inspection or repair. Operators should exclude airplanes never equipped with the affected lavatories from these requirements.
