Use & Relationship

The Instructions for Continued Airworthiness (ICA) will be used to obtain ICA as required by 14 Code of Federal Regulations (CFR) Section 21.50(b), Instructions for continued airworthiness and manufacturer's maintenance manuals having airworthiness limitations sections. (Copies of this document can be obtained or viewed online at: https://www.ecfr.gov/.)

a. 14 CFR Section 21.50(b) requires the holder of a design approval, including either a type certificate or a supplemental type certificate for an aircraft, aircraft engine, or propeller for which application was made after January 28, 1981, to furnish at least one set of complete ICA to the owner of each type aircraft, aircraft engine, or propeller upon its delivery, or upon issuance of the first standard airworthiness certificate for the affected aircraft, whichever occurs later.

b. This Data Item Description (DID) contains the format, content, and intended use information for the data deliverable resulting from the work task described in the solicitation.
