§ 29.807
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 with-
in 90 seconds:
(1) Rotorcraft with a seating capacity
of more than 44 passengers.
(2) Rotorcraft with all of the fol-
lowing:
(i) Ten or more passengers per pas-
senger exit as determined under
§ 29.807(b).
(ii) No main aisle, as described in
§ 29.815, for each row of passenger seats.
(iii) Access to each passenger exit for
each passenger by virtue of design fea-
tures of seats, such as folding or break-
over seat backs or folding seats.
(e) A combination of analysis and
tests may be used to show that the
rotorcraft is capable of being evacu-
ated within 90 seconds under the condi-
tions specified in § 29.803(d) if the Ad-
ministrator finds that the combination
of analysis and tests will provide data,
with respect to the emergency evacu-
ation capability of the rotorcraft,
equivalent to that which would be ob-
tained by actual demonstration.

§ 29.805
Flight crew emergency exits.
(a) For rotorcraft with passenger
emergency exits that are not conven-
ient to the flight crew, there must be
flight crew emergency exits, on both
sides of the rotorcraft or as a top
hatch, in the flight crew area.
(b) Each flight crew emergency exit
must be of sufficient size and must be
located so as to allow rapid evacuation
of the flight crew. This must be shown
by test.
(c) Each exit must not be obstructed
by water or flotation devices after a
ditching. This must be shown by test,
demonstration, or analysis.

§ 29.807
Passenger emergency exits.
(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 rec-
tangular opening of not less than 24
inches wide by 48 inches high, with cor-
ner 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 cor-
ner radii not greater than one-third the
width of the exit, in the side of the fu-
selage with a step-up inside the rotor-
craft 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-of-
fuselage. Emergency exits must be ac-
cessible to the passengers and, except
as provided in paragraph (d) of this sec-
tion, must be provided in accordance
with the following table:

(c)
Passenger emergency exits; other
than side-of-fuselage. In addition to the
requirements of paragraph (b) of this
section—
(1) There must be enough openings in
the top, bottom, or ends of the fuselage
to allow evacuation with the rotorcraft
on its side; or
(2) The probability of the rotorcraft
coming to rest on its side in a crash
landing must be extremely remote.
(d)
Ditching emergency exits for pas-
sengers. If certification with ditching
