Airworthiness Directive 2015-14-06
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 and 747-8F series airplanes. This AD was prompted by an analysis, which indicated that in a limited flight envelope with specific conditions, divergent flutter could occur during a high g-load maneuver in combination with certain system failures. This AD requires replacing the lateral control electronic (LCE) modules, replacing the inboard elevator power control packages (PCPs), installing new external compensators for the PCPs, and revising the maintenance or inspection program. We are issuing this AD to prevent certain system failures from resulting in divergent flutter, and subsequent loss of continued safe flight and landing.
Which aircraft AD 2015-14-06 applies to
Applies to Model 747-8 and 747-8F airplanes identified in Boeing Alert Service Bulletin 747-27A2506 dated February 3, 2014, or Boeing Service Bulletin 747-27A2513, Revision 1, dated July 18, 2014; or to Model 747-8 airplanes operated less than 1,200 flight hours per calendar year.
Whether AD 2015-14-06 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.
