## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD was prompted by events of excessive rudder pedal inputs and consequent high loads on the vertical stabilizer on several airplanes. High loads on the vertical stabilizer that exceed ultimate design loads could cause failure of the vertical stabilizer and consequent reduced controllability of the airplane. The proposed AD would require actions that are intended to address this unsafe condition.
