## Summary

We propose to adopt a new airworthiness directive (AD) for all Quartz Mountain Aerospace, Inc. Model 11E airplanes. This proposed AD would require you to clean and lubricate the aileron pushrod bearings. This proposed AD results from reports of the aileron control stick force increasing and of the controls being very noisy. We are proposing this AD to detect and correct insufficient lubrication and residual metallic paint particles in the pushrod end ball joints, which could result in difficulty actuating aileron controls sometime during flight after takeoff. This condition could lead to difficulty controlling the airplane in flight.
