What to do
Operators of Boeing 787-8, 787-9, and 787-10 airplanes must perform a one-time inspection of the affected PSU oxygen panel assemblies within 36 months of October 22, 2025. If discrepancies are found, they must carry out the required on-condition actions or replace the assemblies with compliant parts. Installation of affected PSU oxygen panel assemblies is prohibited after the effective date.
Summary
The Federal Aviation Administration's Airworthiness Directive 2025-18-02 addresses an unsafe condition affecting all Boeing 787-8, 787-9, and 787-10 airplanes. This directive requires inspection of passenger service unit (PSU) oxygen panel assemblies installed in the forward-most position of a center stow bin due to the risk of oxygen supply tubing becoming kinked. The AD prohibits installation of affected parts and mandates corrective actions to ensure safety.
What changed
This new airworthiness directive introduces a one-time inspection requirement for specific PSU oxygen panel assemblies on Boeing 787 models and prohibits installation of affected parts. The compliance time was extended to 36 months to allow operators to align inspections with scheduled maintenance. Additionally, the AD provides options for replacing discrepant PSU oxygen panel assemblies rather than only repairing them.
Why it matters
This AD is critical for aviation professionals as it addresses a potential oxygen supply failure risk that could impact passenger safety. Operators and maintenance organizations must incorporate the inspection and corrective actions into their maintenance planning to remain compliant and avoid operational disruptions. The extended compliance time helps reduce maintenance burden by allowing integration with routine checks.
