## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. This proposed AD was prompted by a report that bearings in the elevator buss assembly could have been installed incorrectly (including being installed without the application of sealant) during production. This proposed AD would require detailed inspections of the elevator buss assembly bearings and bearing housings for any crack and indication of sealant application, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
