Airworthiness Directive · Amendment 39-16312 · Flight controls
Quartz Mountain Aerospace, Inc. Model 11E Airplanes
This AD applies to Model 11E airplanes, all serial numbers, that are certificated in any category.
We are adopting a new airworthiness directive (AD) for all Quartz Mountain Aerospace, Inc. Model 11E airplanes. This AD requires you to clean and lubricate the aileron pushrod bearings. This AD results from reports of the aileron control stick force increasing and of the controls being very noisy. We are 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.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Clean and lubricate the aileron pushrod bearings | Within the next 10 hours time-in-service (TIS) after July 6, 2010 (the effective date of this AD) | Follow Quartz Mountain Aerospace Mandatory Service Bulletin No. SB 09-02, dated May 5, 2009. |
| (2) Lubricate the aileron pushrod bearings | Within 50 hours TIS after the cleaning and lubrication required by paragraph (f)(1) of this AD. Repetitively thereafter at intervals not to exceed 50 hours TIS | Follow Quartz Mountain Aerospace Mandatory Service Bulletin No. SB 09-02, dated May 5, 2009. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
