A replacement bracket for a type-certificated aircraft is produced by a manufacturer under a Parts Manufacturer Approval (PMA). What gives this part legal authority for installation on the aircraft?

  1. AA statement from the mechanic that the part looks equivalent to the original
  2. BThe PMA holder's FAA-approved design and production approval under 14 CFR part 21
  3. CThe part's inclusion in the aircraft's original type certificate data sheet
  4. DThe part is accompanied by an FAA Form 8130-3 issued by the aircraft owner
Show answer & explanation

Correct answer: B. The PMA holder's FAA-approved design and production approval under 14 CFR part 21

A Parts Manufacturer Approval (PMA), granted under 14 CFR part 21, Subpart K, is an FAA design and production approval that allows a manufacturer to produce replacement or modification parts for installation on a type-certificated product, giving those parts legal standing without a separate approval for each installation.

Why the other options are wrong

  • A. A mechanic's personal judgment cannot substitute for a formal FAA approval.
  • C. PMA parts do not need to appear on the original type certificate data sheet.
  • D. Form 8130-3 is issued by an authorized FAA representative/manufacturer, not the aircraft owner, and is not the basis of PMA authority.

Parts Manufacturer Approval (PMA)

An FAA approval under 14 CFR part 21, Subpart K, authorizing a manufacturer to produce replacement or modification parts for installation on type-certificated products.

  • Combines design and production approval in one authorization
  • Distinct from TSO, which authorizes standardized appliances/materials
  • PMA parts are legally installable without a separate field approval

Memory trick: 'PMA = Pre-approved Manufacturing Authority.'
