Where It Sits in Continuing Airworthiness
Dual Release forms part of the technical framework used to establish, maintain or document aircraft airworthiness. Applicability depends on aircraft type, authority, approved maintenance data and the operator's maintenance programme.
How It Is Used
The exact wording and approvals matter because a document that looks similar may not provide the release basis required by the installing operator.
Records and Transaction Impact
Technical status must be supported by current records. Buyers, lessors, lenders and MRO organizations normally verify the applicable document, revision, compliance status and remaining maintenance exposure rather than relying on a description alone.
