SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, and -300F airplanes. This AD was prompted by a report of a main landing gear (MLG) collapse event following maintenance where a grinder was operating outside of its input parameters, resulting in possible heat damage to the outer cylinder of the MLG. This AD requires replacing affected outer cylinders. The FAA is issuing this AD to address the unsafe condition on these products.

Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all The Boeing Company Model 767-200, -300, and -300F series airplanes. The NPRM published in the
Federal Register
on June 20, 2024 (89 FR 51856), corrected July 15, 2024 (89 FR 57377). The NPRM was prompted by a report of a MLG collapse event following maintenance where a grinder was operating outside of its input parameters, resulting in possible heat damage to the outer cylinder of the MLG. In the NPRM, the FAA proposed to require replacing any affected outer cylinders. The FAA is issuing this AD to address any heat damage to the outer cylinder of the landing gear, which could result in the inability of a principal structural element to sustain limit load, gear collapse resulting in loss of control of the airplane, and potential for off-runway…
