Changes requiring a new type
certificate.
Each person who proposes to change
a product must apply for a new type
certificate if the FAA finds that the
proposed change in design, power,
thrust, or weight is so extensive that a
substantially complete investigation of
compliance with the applicable regula-
tions is required.

§ 21.21
Issue of type certificate: nor-
mal, utility, acrobatic, commuter,
and transport category aircraft;
manned free balloons; special class-
es of aircraft; aircraft engines; pro-
pellers.
An applicant is entitled to a type cer-
tificate for an aircraft in the normal,
utility, acrobatic, commuter, or trans-
port category, or for a manned free bal-
loon, special class of aircraft, or an air-
craft engine or propeller, if—
(a) The product qualifies under § 21.27;
or
(b) The applicant submits the type
design, test reports, and computations
necessary to show that the product to
be certificated meets the applicable
airworthiness, aircraft noise, fuel vent-
ing, and exhaust emission require-
ments of this subchapter and any spe-
cial conditions prescribed by the FAA,
and the FAA finds—
(1) Upon examination of the type de-
sign, and after completing all tests and
inspections, that the type design and
the product meet the applicable noise,
fuel venting, and emissions require-
ments of this subchapter, and further
finds that they meet the applicable air-
worthiness requirements of this sub-
chapter or that any airworthiness pro-
visions not complied with are com-
pensated for by factors that provide an
equivalent level of safety; and
(2) For an aircraft, that no feature or
characteristic makes it unsafe for the
category in which certification is re-
quested.
