Applicability: Model C-212 series airplanes, certificated in any category.

Compliance: Required within 60 days after the effective date of this AD, unless previously accomplished.

To prevent reduced controllability of the airplane, accomplish the following:

A. Modify the propeller speed and pitch control system so that the control cannot be moved into reverse thrust while in flight, and so that the propeller pitch settings cannot be adjusted for ground operation while in flight, in accordance with CASA Service Bulletin 212-76-07, dated July 27, 1990, or in a manner approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

B. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

NOTE: The request should be submitted directly to the Manager, Standardization Branch, ANM- 113, and a copy sent to the cognizant FAA Principal Inspector (PI). The PI will then forward comments or concurrence to the Manager, Standardization Branch, ANM-113.

C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Construcciones Aeronauticas S.A., Getafe, Madrid, Spain. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 1601 Lind Avenue S.W., Renton, Washington.

Airworthiness Directive 91-03-10 supersedes AD 90-04-11. Amendment 39-6508.

This amendment (39-6883, AD 91-03-10) becomes effective on March 11, 1991.
