Airworthiness Directive 2008-16-12
recurringAirworthiness Directives; Boeing Model 777-200 Series Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 series airplanes. This AD requires repetitive inspections for any wrinkle in certain external skin panels, and for cracking at the fuselage bulkhead shear tie end fastener locations at certain stations of Section 48 of the fuselage; and doing related investigative and corrective actions if necessary. This AD results from a report of cracks found in the external skin on the left and right sides of the Section 48 panel of the fuselage on two airplanes with skin wrinkles found at two of the external crack locations. We are issuing this AD to detect and correct wrinkles and cracks in certain external skin panels of Section 48, which could join together and result in reduced structural integrity of support structure for the vertical and horizontal stabilizers and inability of the airplane to sustain limit loads.
Which aircraft AD 2008-16-12 applies to
serial/model applicability read from the AD body — confirm the exact serial/model from the records
Whether AD 2008-16-12 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.
