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.

Why a cheap aircraft part can cost more than a new one

A painted one-minute walk through the inspector's rules, then the real regulations, paperwork and fraud case behind them.

Read the narration

An aircraft part that looks like a bargain can be the most expensive part in the hangar. This inspector shows why the paperwork matters as much as the metal. Every part on a jet needs a paper trail: an original data plate, a history that goes all the way back to the factory, and a release tag from an approved shop. The tool checks for all three. If the data plate or the history is missing, the part becomes a suspected unapproved part. It goes into quarantine, and the model adds eight hundred dollars for audit and legal risk. If only the shop certification is missing, the part is held for testing at a certified repair station. That adds four hundred dollars, plus three hundred more for parts pulled from scrapped or salvaged aircraft. Now run the default case. A sixty-five percent discount turns a thousand dollar part into three hundred fifty. Add quarantine and teardown, and it really costs fourteen hundred fifty, almost half again the factory price. This is not hypothetical. From twenty nineteen to twenty twenty-three, a supplier called AOG Technics sold engine parts with forged paperwork, and jets around the world were grounded while airlines checked. Try the presets and see which paper trail passes.

What a suspected unapproved part is

A part that may not meet the requirements of an approved part, for example because its origin or maintenance history can't be proven. The FAA's current guidance is Advisory Circular 21-29D (2016); the tool's banner still cites the older 21-29C.

The release tag

FAA Form 8130-3, the Authorized Release Certificate, documents that a new part conforms to its design or that a used part is approved for return to service after maintenance. Only FAA inspectors and specifically authorized organizations and people may sign it.

Repair stations

Certified repair stations under 14 CFR Part 145 can inspect, test and overhaul parts and approve them for return to service. That is the route the tool sends a part with good history but no shop certification.

The AOG Technics case

AOG Technics forged documents for CFM56 engine parts sold to airlines and maintenance firms. Its director pleaded guilty and in February 2026 was sentenced to 56 months; reporting put the scheme at more than 60,000 parts.

What the tool's costs mean

The $800 quarantine penalty, $400 test fee and $300 teardown fee are illustrative figures built into this tool, not industry prices. The point is the shape: a missing document can erase a large discount.

Try it in the tool

  1. Click the Default (High Risk SUP) preset and read the cost breakdown: $350 to buy, $800 risk, $300 teardown.
  2. Click OEM Direct Factory: full price, every check passes, no extra costs.
  3. Try Organ Donor + MRO: a used part at 50% off that passes because its history and shop certification are complete.
  4. Untick only the MRO box on a part with full history and watch the verdict change from rejected to a conditional hold.
