2018-19-11: Wings

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2018-19-11 Viking Air Limited: Amendment 39-19411; Docket No. FAA- 2017-0867; Product Identifier 2017-CE-021-AD. (a) Effective Date This AD becomes effective October 30, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Viking Air Limited Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes, all serial numbers, certificated in any category. (d) Subject Air Transport Association of America (ATA) Code 57: Wings. (e) Reason This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI [[Page 48366]] describes the unsafe condition as cracking found in the wing rear spar web at the wing station (WS) where the flap outboard hinge is attached. We are issuing this AD to detect and correct cracks in the wing rear spars and the flap/aileron hinge arm support brackets. This condition, if not corrected, could result in structural failure with consequent loss of control of the airplane. (f) Actions and Compliance Unless already done, do the actions in paragraphs (f)(1) through (5) of this AD: (1) Within 400 hours time-in-service (TIS) after October 30, 2018 (the effective date of this AD) or within 6 months after October 30, 2018 (the effective date of this AD), whichever occurs first, visually inspect the left-hand and right-hand wing rear spar and flap/aileron hinge arm support brackets by following the Accomplishment Instructions of Viking DHC-2 Beaver Service Bulletin Number: V2/0009, Revision A, dated February 10, 2017 (SB V2/0009, Revision A). (2) For airplanes with an agricultural configuration installed (SOO Mod 2/984), within 400 hours TIS after October 30, 2018 (the effective date of this AD) or within 6 months after October 30, 2018 (the effective date of this AD), whichever occurs first, inspect the exterior store support arm bracket at WS 101.24 by following the Accomplishment Instructions of SB V2/0009, Revision A. (3) If any discrepancies are found during the inspections required in paragraphs (f)(1) and (2) of this AD, before further flight, repair or replace using a method approved by the Manager, New York ACO Branch, FAA; Transport Canada; or Viking Air Limited's Transport Canada Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature. (4) Within 30 days after completing the inspections required in paragraphs (f)(1) and (2) of this AD, using the Operator Reply Form on page 7 of SB V2/0009, Revision A, report the inspection results to Viking Air Limited at the address specified in paragraph (i)(3) of this AD. (5) As of October 30, 2018 (the effective date of this AD), do not install a wing on any airplane affected by this AD unless it has been inspected as specified in paragraphs (f)(1) of this AD and paragraph (f)(2) of this AD, if applicable, and is found free of any discrepancies.
