The FAA proposes inspecting elevator-control bearings on an estimated 95 U.S.-registered 737-8, 737-9 and 737-8200 airplanes after a report that the bearings may have been installed incorrectly in production, including without sealant, and the Boeing bulletin it would make mandatory gives operators 126 months to look.
A proposed airworthiness directive published September 21 (Docket No. FAA-2026-8811) would require detailed inspections of the elevator buss assembly bearings and bearing housings on certain Boeing 737-8, 737-9 and 737-8200 airplanes; an FAA directive from 2020 calls the first two the 737 MAX. The FAA says it received a report that the bearings 'could have been installed incorrectly (including being installed without the application of sealant) during production', which could lead to cracking in the bearings and housings and premature failure of the assembly's crank arms and could impact elevator pitch control. It estimates 95 U.S.-registered airplanes are affected, at $1,955 per airplane for the inspection and $185,725 for U.S. operators; replacing a whole assembly would cost an estimated $98,496. The deadline is not in the proposal. It sits in the Boeing bulletin posted in the docket: 126 months, which for airplanes already flying would count from the final rule's effective date, with no repeat inspection. Under the bulletin, a crack or missing sealant must be fixed before further flight. The 737 MAX-7, certified August 3, is not among the airplanes listed. Comments are due November 5, 2026.
