Airworthiness Directive 2017-22-10
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 747-400, 747-400F, and 747-8F series airplanes. This AD was prompted by reports of failure of the fastener assemblies on the crew access ladder handrails. This AD requires replacing the fastener assemblies. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2017-22-10 applies to
Applies to airplanes identified in Boeing Special Attention Service Bulletin 747-25-3693, dated November 10, 2016.
Whether AD 2017-22-10 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.
