The requirement is a Critical Safety Item (CSI) with IUID applicability, early delivery acceptable, and surplus use prohibited. The contractor must provide a detailed cover letter containing all solicitation data (engine type, company CAGE, point‑of‑contact information, size, qualification designation, waiver criteria, SAR type, NSN/part numbers, nomenclature, submittal category, ERRC code, SAR package format, disposition, etc.) and certify compliance with FAR 52.246‑11 higher‑level contract quality requirements, government QA provisions, and DFARS 252.211.7003. Required submissions include the SAR package (or waiver request if applicable), ESA/OEM approval letter, novation letter, certification of access to master tooling and related data, and complete IMS/MPS documentation per Category I or II guidelines, including sampling plans and detailed process steps. The ESA will conduct a Self‑Assessment Checklist (SAC) and, if needed, a Site Survey Checklist (SSC) within specified timeframes, and may issue a Source Resubstantiation Request (SRR) with a three‑day response window. Approval duration follows the matrix (CSI 3 years, AFI 20‑106 7 years), and any significant changes to ownership, address, processes, or quality must trigger a resubmission of the SAR package.
