Airworthiness Directive · Amendment 39-17954 · Stabilizers
Viking Air Limited Airplanes
This AD applies to Viking Air Limited Models DHC-3 airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for Viking Air Limited Model DHC-3 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as looseness of the horizontal stabilizer actuator mounting block in the forward-aft and side-to-side directions. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) and (f)(2).
(1) Within the next 100 hours time-in-service after September 16, 2014 (the effective date of this AD) or within the next 90 days after September 16, 2014 (the effective date of the this AD), whichever occurs first, inspect the horizontal stabilizer actuator (trim jack) for movement or defects following the Accomplishment Instructions in Viking Service Bulletin No. V3/0005, Revision `A', dated May 27, 2014.
(2) If any movement or defects are found during the inspection required by paragraph (f)(1) of this AD, before further flight, you must contact Viking Air Limited to obtain FAA-approved repair instructions approved specifically for compliance with this AD and incorporate those instructions. You can find contact information for Viking Air Limited in paragraph (i)(3) of this AD. Use the Service Bulletin V3/0005—Operator Reply Form found in Viking Service Bulletin No. V3/0005, Revision `A', dated May 27, 2014, to report details of the inspection findings.
