Airworthiness Directive 2017-17-16
recurringAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This AD was prompted by a report of cracking of the vertical stiffener in the nose wheel well. This AD requires repetitive inspections of the nose wheel well bulkhead stiffener for any cracking, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2017-17-16 applies to
Applies to airplanes identified in Boeing Alert Service Bulletin 767-53A0275, dated January 5, 2017. Installation of STC ST01920SE does not affect the ability to accomplish the required actions; no AMOC is necessary for airplanes with STC ST01920SE installed.
Whether AD 2017-17-16 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.
