The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, and -300F series airplanes. This proposed AD comes in response to a report of a main landing gear (MLG) collapse event following maintenance where a grinder was operating outside of its input parameters, potentially causing heat damage to the outer cylinder of the MLG. The FAA has determined that this poses an unsafe condition that must be addressed.
The proposed AD would require the replacement of any affected outer cylinders on the specified Boeing 767 models. Comments on this proposed AD must be received by the FAA by August 5, 2024. Comments can be submitted through various methods, including the Federal eRulemaking Portal, fax, mail, or hand delivery.
The FAA invites relevant data, views, or arguments about this proposal and encourages stakeholders to provide detailed comments referencing specific portions of the proposal. The agency will consider all comments received and may amend the proposal based on feedback received.
Background information provided by the FAA indicates that an investigation following an MLG collapse event revealed that a grinder used during previous maintenance activities was operating outside of its parameters. This resulted in potential heat damage to 83 Model 767 MLG outer cylinders, which could lead to structural issues, gear collapse, and fuel spillage if not addressed.
The proposed AD would require affected operators to inspect maintenance records or perform an inspection of the left and right MLG outer cylinders for any affected part numbers and serial numbers, followed by the replacement of affected cylinders as necessary. The estimated costs of compliance with this proposed AD for U.S. operators are outlined, including labor and parts costs.
The FAA asserts its authority to issue this proposed rulemaking under Title 49 of the United States Code, which specifies the agency’s mandate to promote aviation safety. The proposed AD is deemed necessary to address the identified unsafe condition and ensure the continued safe operation of the specified Boeing 767 models.
In conclusion, the FAA has proposed a new AD for certain Boeing 767 models to address potential safety issues related to MLG outer cylinders. Stakeholders are encouraged to submit comments on the proposal before the deadline, and the agency will consider all feedback received before finalizing the AD. This regulatory action aims to enhance aviation safety and prevent any further incidents related to the identified maintenance issue..
