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

D. 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 Fokker Aircraft USA, Inc., 1199 N. Fairfax Street, Alexandria, Virginia 22314.
