ACTION: Final rule; request for comments. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-2C series airplanes. This AD was prompted by a report that insufficient clearance was found between the right stabilizer trim shut-off control wire (bundle W0589) and an elevator control cable. This AD requires a one-time inspection for insufficient clearance between the elevator control cable and wire bundle W0589 on the airplane's left crown, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 11, 2022. The FAA must receive comments on this AD by November 10, 2022. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to regulations.gov.

SUPPLEMENTARY INFORMATION: Background The FAA has received a report indicating that insufficient clearance was found between wire bundle W0589 and the elevator control cable. Wire bundle W0589 includes wiring between the aisle stand stabilizer trim cutout switches and the hydraulic shutoff valves. The insufficient clearance was discovered during production quality assurance inspections, and affects thirteen model 767-2C airplanes. This condition, if not addressed, could result in abrasion of the wire bundle due to movement of the elevator control cable during normal airplane operation. This damage could lead to an open-circuit condition, which could inhibit the ability to shut off hydraulic supply to the “C” stab trim control module and motor. This condition, in conjunction with a runaway horizontal stabilizer condition, may lead to loss of continued safe flight and landing. FAA's Determination The FAA is is…
