Airworthiness Directive · Amendment 39-22412 · Equipment/furnishings
Viking Air Limited (Type Certificate Previously Held by Bombardier, Inc.; Canadair Limited) Airplanes
This AD applies to all Viking Air Limited (Type Certificate previously held by Bombardier, Inc.; Canadair Limited) Model CL-215-1A10 and CL-215-6B11 (CL-215T Variant) airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 96-12-11, which applied to all Canadair Model CL-215-1A10 airplanes. AD 96-12-11 required repetitive inspections to detect discrepancies of the microswitches fitted at the water door actuator; replacement of any discrepant microswitch; and modification of the water door actuator switches, which terminates the repetitive inspections. This AD continues to require the modification of the water door actuator switches. This AD also requires modification of the water door solenoid valve common grounds, adds airplanes to the applicability, and specifies a parts installation limitation for the water door solenoid valve. This AD was prompted by reports of uncommanded opening of the water doors during flight and water scooping. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (d) of AD 96-12-11, with revised service information and a new compliance time. For Model CL-215-1A10 airplanes: Within 24 months after the effective date of this AD, modify the water door microswitches in accordance with Viking Service Bulletin 215-389, Revision 3, dated February 15, 2023.
Within 24 months after the effective date of this AD, install two new water door solenoid valve common grounds in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin 215-A497, dated November 16, 1998.
(1) As of the effective date of this AD, only the parts identified in paragraphs (i)(1)(i) through (iii) of this AD are allowed for use as a replacement part for the water door solenoid valve.
(i) Water door solenoid valve, selector assembly, part number (P/N) 362-0377, on which the design change modification specified in Viking Technical Bulletin V215/0713, Revision A, dated June 20, 2022; or Viking Technical Bulletin V215/3214, Revision A, dated June 20, 2022; is incorporated.
(ii) Water door solenoid valve, 4-way selector valve, P/N 20P16-2, specification control drawing (SCD) 215T92392-2, or superseding part with internal back electro-motive force (EMF) protection.
(iii) Water door solenoid valve, 4-way selector valve, P/N 20P16-2, SCD 215T92392-2, or superseding part with internal back EMF protection on which the design change modification specified in Viking Technical Bulletin V215/0713, Revision A, dated June 20, 2022; or Viking Technical Bulletin V215/3214, Revision A, dated June 20, 2022; is incorporated.
(2) For airplanes on which a part identified in paragraph (i)(1)(i) or (iii) of this AD is installed: Before further flight after installation, revise the exiting maintenance or inspection program to incorporate the information for Chapter 25-70-00 specified in Viking Temporary Revision 25-27, dated April 13, 2022, into the Viking CL-215 Maintenance Manual, PSP 292.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
