Subpart A - General
Section 35.1 Applicability.
(a) This part prescribes airworthiness
standards for the issue of type certificates and changes to those certificates,
for propellers.
(b) Each person who applies under
part 21 for such a certificate or change

must show compliance with the applicable requirements of this part.
(c) An applicant is eligible for a propeller type certificate and changes to
those certificates after demonstrating
compliance with subparts A, B, and C
of this part. However, the propeller
may not be installed on an airplane unless the applicant has shown compliance with either Section 23.2400(c) or Section 25.907 of
this chapter, as applicable, or compliance is not required for installation on
that airplane.
(d) For the purposes of this part, the
propeller consists of those components
listed in the propeller type design, and
the propeller system consists of the
propeller and all the components necessary for its functioning, but not necessarily included in the propeller type
design.

Section 35.2 Propeller configuration.
The applicant must provide a list of
all the components, including references to the relevant drawings and
software design data, that define the
type design of the propeller to be approved under Section 21.31 of this chapter.
[Amdt. 35-8, 73 FR 63346, Oct. 24, 2008]

Section 35.3 Instructions for propeller installation and operation.
The applicant must provide instructions that are approved by the Administrator. Those approved instructions
must contain:
(a) Instructions for installing the
propeller, which:
(1) Include a description of the operational modes of the propeller control
system and functional interface of the
control system with the airplane and
engine systems;
(2) Specify the physical and functional interfaces with the airplane, airplane equipment and engine;
(3) Define the limiting conditions on
the interfaces from paragraph (a)(2) of
this section;
(4) List the limitations established
under Section 35.5;
(5) Define the hydraulic fluids approved for use with the propeller, including grade and specification, related
