Aviation Industry Sourcing Context & Regulatory Background

Commercial airlines operate in an environment governed strictly by FAA 14 CFR § 21.9 (replacement and modification parts) and Advisory Circular 21-29C (Detecting and Reporting Suspected Unapproved Parts). Sourcing components from retired aircraft ("organ donors" such as McDonnell Douglas MD-88s or Boeing 717s) offers substantial upfront savings, but parts stripped from crashed or scrapped airframes without back-to-birth logs pose extreme safety risks. Without verified FAA Form 8130-3 airworthiness release certificates and Part 145 MRO bench testing, unapproved parts must be quarantined immediately.
