Final copy of telegraphic airworthiness directive, issued December 9, 1988. Applicability: Model DHC-8-100 series airplanes, Serial Numbers 1 through 126, certificated in any category. Compliance: Required within the next 50 hours time-in-service, unless previously accomplished. To preclude the possibility of deformation or jamming of the elevator control system, accomplish the following: A. Remove inspection panels 121 BL and 121 BR or the floor panel in flight compartment aft of center console, and inspect the elevator control quadrant levers, Item 160/Part Numbers 82710146-101 (left side) and 82710146-102 (right side), for correct installation. Ensure that the curved portion of each lever points forward. B. If both left and right levers curve forward, no further action is necessary and the inspection panels may be reinstalled. C. If either lever curves rearward, inspect the associated push rod for evidence of bending or binding. Replace, prior to further flight, any incorrectly installed levers and damaged push rods with new or serviceable units, as applicable. D. 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, New York Aircraft Certification Office, FAA, New England Region. NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who may add any comments and then send it to the Manager, New York Aircraft Certification Office. E. 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 Boeing of Canada, Ltd., de Havilland Division, Garratt Boulevard, Downsview, Ontario M3K 1Y5, Canada.
