Code of Federal Regulations - Title 14

Federal Aviation Administration, DOT

§ 25.795

(ii) A 15-pound per square-inch (103.4

kPa) pressure load if the projected sur-
face area of the component is greater
than 4 square feet. Any single dimen-
sion greater than 4 feet (1.22 meters)
may be assumed to be 4 feet (1.22 me-
ters) in length; and

(iii) A 6-inch (0.152 meters) displace-

ment, except where limited by the fu-
selage contour, from a single point
force applied anywhere along the dis-
tribution system where relative move-
ment between the system and its at-
tachment can occur.

(iv) Paragraphs (b)(3)(i) through (iii)

of this section do not apply to compo-
nents that are redundant and separated
in accordance with paragraph (c)(2) of
this section or are installed remotely
from the cargo compartment.

tificated passenger seating capacity of
more than 60 persons or a maximum
certificated takeoff gross weight of
over 100,000 pounds (45,359 Kilograms)
must comply with the following:

(1)

Least risk bomb location. An air-

plane must be designed with a des-
ignated location where a bomb or other
explosive device could be placed to best
protect flight-critical structures and
systems from damage in the case of
detonation.

(2)

Survivability of systems. (i) Except

where impracticable, redundant air-
plane systems necessary for continued
safe flight and landing must be phys-
ically separated, at a minimum, by an
amount equal to a sphere of diameter

(

)

(where H

is defined under § 25.365(e)(2)

of this part and D need not exceed 5.05
feet (1.54 meters)). The sphere is ap-
plied everywhere within the fuselage—
limited by the forward bulkhead and
the aft bulkhead of the passenger cabin
and cargo compartment beyond which
only one-half the sphere is applied.

(ii) Where compliance with paragraph

(c)(2)(i) of this section is impracticable,
other design precautions must be taken
to maximize the survivability of those
systems.

(3)

Interior design to facilitate searches.

Design features must be incorporated
that will deter concealment or promote
discovery of weapons, explosives, or

other objects from a simple inspection
in the following areas of the airplane
cabin:

(i) Areas above the overhead bins

must be designed to prevent objects
from being hidden from view in a sim-
ple search from the aisle. Designs that
prevent concealment of objects with
volumes 20 cubic inches and greater
satisfy this requirement.

(ii) Toilets must be designed to pre-

vent the passage of solid objects great-
er than 2.0 inches in diameter.

(iii) Life preservers or their storage

locations must be designed so that
tampering is evident.

(d)

Exceptions. Airplanes used solely

to transport cargo only need to meet
the requirements of paragraphs (b)(1),
(b)(3), and (c)(2) of this section.

(e)

Material Incorporated by Reference.

You must use National Institute of
Justice (NIJ) Standard 0101.04, Ballistic
Resistance of Personal Body Armor,

listic resistance as required by para-
