III airplanes, all serial numbers, certificated in any category. (d) Subject Joint Aircraft System Component (JASC) Code 2000, Airframe. (e) Unsafe Condition 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 describes the unsafe condition as corrosion-related degradation in aging aircraft. The FAA is issuing this AD to detect and address corrosion, which could lead to structural failure with consequent loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) Within 90 days after the effective date of this AD, incorporate into the existing maintenance records required by 14 CFR 91.417(a)(2) or 135.439(a)(2), as applicable for your airplane, the actions and associated thresholds and intervals, including life limits, specified in Parts 2 and 3 of Viking DHC-2 Beaver Supplemental Inspection and Corrosion Control Manual, PSM 1-2-5, Revision 1, dated January 10, 2019 (Viking PSM 1-2-5, Revision 1).
