## Abstract

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.
