(c) [Reserved]
(d) Except as provided in paragraph
(e) of this section, the following categories of rotorcraft must be tested in
accordance with the requirements of
appendix D of this part to demonstrate
that the maximum seating capacity,
including the crewmembers required by
the operating rules, can be evacuated
from the rotorcraft to the ground within 90 seconds:
(1) Rotorcraft with a seating capacity
of more than 44 passengers.
(2) Rotorcraft with all of the following:
(i) Ten or more passengers per passenger exit as determined under
Section 29.807(b).
(ii) No main aisle, as described in

(e) A combination of analysis and
tests may be used to show that the
rotorcraft is capable of being evacuated within 90 seconds under the conditions specified in Section 29.803(d) if the Administrator finds that the combination
of analysis and tests will provide data,
with respect to the emergency evacuation capability of the rotorcraft,
equivalent to that which would be obtained by actual demonstration.

(a) Type. For the purpose of this part,
the types of passenger emergency exit
are as follows:
(1) Type I. This type must have a rectangular opening of not less than 24
inches wide by 48 inches high, with corner radii not greater than one-third the
width of the exit, in the passenger area
in the side of the fuselage at floor level
and as far away as practicable from
areas that might become potential fire
hazards in a crash.
(2) Type II. This type is the same as
Type I, except that the opening must
be at least 20 inches wide by 44 inches
high.
(3) Type III. This type is the same as
Type I, except that - 
(i) The opening must be at least 20
inches wide by 36 inches high; and
(ii) The exits need not be at floor
level.
(4) Type IV. This type must have a
rectangular opening of not less than 19
inches wide by 26 inches high, with corner radii not greater than one-third the
width of the exit, in the side of the fuselage with a step-up inside the rotorcraft of not more than 29 inches.
Openings with dimensions larger than
those specified in this section may be
used, regardless of shape, if the base of
the opening has a flat surface of not
less than the specified width.
(b) Passenger emergency exits; side-offuselage. Emergency exits must be accessible to the passengers and, except
as provided in paragraph (d) of this section, must be provided in accordance
with the following table:
