## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737 airplanes. This proposed AD would require modifying the elevator input torque tube assembly. This proposed AD is prompted by a report of a restriction in the pilots' elevator input control system. We are proposing this AD to prevent loss of elevator control and consequent reduced controllability of the airplane.
