What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of fatigue cracks found on the thrust reverser (TR) outer V-blade (OVB) during scheduled maintenance and inspections. This proposed AD would require repetitive inspections of the upper, center, and lower segments of the OVB and the inner radius of the OVB for any crack and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
