The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by a report of improper grinding of the inner diameter of the main landing gear (MLG) outer cylinders, resulting in possible heat damage to the outer cylinders. This AD requires a records check or inspection to determine if an affected outer cylinder is installed and replacing all affected outer cylinders. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-32A1585 RB, dated January 15, 2024, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-32A1585 RB, dated January 15, 2024.

Where the “Boeing Recommended Compliance Time” column in the table under the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-32A1585 RB, dated January 15, 2024, refers to the original issue date of Boeing Alert Requirements Bulletin 737-32A1585 RB, this AD requires using the effective date of this AD.
