Airworthiness Directive 2021-12-12
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This AD was prompted by a report of discrepant spoiler assemblies, which have the wrong splice bar installed and lack reinforcing doublers, and by reports that some splice bars were shipped for installation on Model 717-200 airplanes, although they were not eligible for installation on Model 717-200 airplanes and were identified incorrectly with the Model 717-200 splice bar part number. This AD requires a one-time inspection of the left- and right-wing inboard and outboard spoiler assemblies, for the correct configuration of the splice bar and doublers, and repair or replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2021-12-12 applies to
Whether AD 2021-12-12 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.
