Proposed Airworthiness Directives for Boeing Airplanes
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The FAA proposes a new airworthiness directive (AD) for Boeing 787-8, 787-9, and 787-10 airplanes due to findings of fatigue cracks in thrust reverser components during maintenance. The directive mandates repetitive inspections of specific blade segments to ensure safety and prevent structural failures during flight operations. Comments on this proposed AD are invited until May 22, 2026.

Key Changes
- Mandatory repetitive inspections for thrust reverser components.
- Focus on safety to prevent structural failures.
- Comments accepted until the specified deadline.
Obligations
What this law requires
Operators of Boeing 787-8, 787-9, and 787-10 airplanes must perform repetitive detailed inspections of the upper, center, and lower segments of the thrust reverser outer V-blade (OVB) for cracks on both the left and right thrust reverser halves on both engines.
Operators must perform repetitive surface high frequency eddy current (HFEC) inspections of the inner radius of the thrust reverser OVB for any crack on both the left and right thrust reverser halves on both engines.
When cracks are detected during inspection, operators must perform a surface HFEC inspection at the crack location as an on-condition action.
Operators must perform detailed inspections of the upper, center, and lower segments of the OVB to identify any worn and missing dry film lubricant and restore the dry film lubricant as applicable.
Operators must replace an affected thrust reverser half when required as an on-condition action following inspection findings.
