MANUFACTURER: Quartz Mountain Aerospace, Inc.
Model 11E Airplanes SUBJECT: Airworthiness Directive 2010-11-07
SUMMARY: This AD requires the cleaning and
lubrication of the aileron pushrod bearings. This AD results
from reports of the aileron control stick force increasing and of
the controls being very noisy. The FAA is issuing 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.
