Show the answer and explanation

Correct answer: B. The TCDS is part of the type certificate

  • A — incorrect The TCDS does not replace the type certificate; it is a component of it that describes the product and its limitations.
  • B — correct The handbook states that 14 CFR part 21, § 21.41 indicates the TCDS is part of the type certificate, and as such is evidence that the product has been type certificated.
  • C — incorrect The TCDS is not advisory; it is part of the type certificate and sets forth conditions and limitations under which the airworthiness requirements were met.

BACKGROUND

A type certificate (TC) is issued by the FAA when a new aircraft, engine, or propeller is found to meet the applicable safety standards. The type certificate data sheet (TCDS) is a formal description of the product that lists limitations and information required for type certification, such as airspeed limits, weight limits, engine make and model, fuel type, and minimum crew. FAA-H-8083-30B chapter 2 notes that TCDSs were first published in January 1958 and that 14 CFR § 21.41 indicates they are part of the TC, so a TCDS is evidence the product has been type certificated. TCDSs are generally compiled from details supplied by the TC holder and are categorized by TC holder and product type.

STUDY TIP

Treat the TCDS as approved data that belongs to the type certificate itself, which is why it can substantiate a major repair or alteration.

KEY POINTS

  • A TCDS is a formal description of the aircraft, engine, or propeller with its limitations.
  • Under § 21.41 the TCDS is part of the type certificate.
  • TCDSs are categorized by TC holder and product type.
