Airworthiness Directive · Amendment 39-21540 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 737-8 and 737-9 airplanes, certificated in any category, with an original airworthiness certificate or original export certificate of airworthiness issued before November 20, 2020.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-8 and 737-9 (737 MAX) airplanes. This AD was prompted by the determination that additional Certification Maintenance Requirements (CMRs) are necessary. This AD requires a revision of the existing maintenance or inspection program to incorporate three additional CMRs. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the CMR item information identified in figure 1 to paragraph (g) of this AD. For airplanes that have exceeded the CMR interval, in total flight hours (FHs), for a required CMR item, the associated task must be done before further flight after revision of the maintenance or inspection program.
Note 1 to paragraph (g): The CMR tasks and intervals specified in figure 1 to paragraph (g) of this AD correspond to the items identified in Boeing Certification Maintenance Requirements Document D626A011-9-03, dated July 2020. The information in both sources is identical.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
