CHAPTER 11. SECURITY
11.1 Aeroplanes used for domestic
commercial operations
Recommendation.— International Standards and Recommended
Practices set forth in this chapter should be applied by
all Contracting States for aeroplanes engaged in domestic
commercial operations (air services).
11.2 Least-risk bomb location
For aeroplanes of a maximum certificated take-off mass in
excess of 45 500 kg or with a passenger seating capacity
greater than 60 and for which the application for certification
was submitted on or after 12 March 2000, consideration shall
be given during the design of the aeroplane to the provision of
a least-risk bomb location so as to minimize the effects of a
bomb on the aeroplane and its occupants.
11.3 Protection of the flight crew compartment
Recommendation.— In all aeroplanes, which are required by
Annex 6, Part I, Chapter 13 to have an approved flight crew
compartment door, and for which an application for amending
the type certificate to include a derivative type design is
submitted to the appropriate national authority, consideration
should be given to reinforcing the flight crew compartment
bulkheads, floors and ceilings so as to resist penetration by
small arms fire and grenade shrapnel and to resist forcible
intrusions, if these areas are accessible in flight to passengers
and cabin crew.
Note.— Standards and Recommended Practices concerning
the requirements for the flight crew compartment door in all
commercial passenger-carrying aeroplanes are contained in
Annex 6, Part I, Chapter 13.
11.4 Interior design
For aeroplanes of a maximum certificated take-off mass in
excess of 45 500 kg or with a passenger seating capacity
greater than 60 and for which the application for certification
was submitted on or after 12 March 2000, consideration shall
be given to design features that will deter the easy
concealment of weapons, explosives or other dangerous
objects on board aircraft and that will facilitate search
procedures for such objects.

ANNEX 8 IIIB-A-1 2/3/04
PART IIIB. AEROPLANES OVER 5 700 KG FOR WHICH APPLICATION FOR
CERTIFICATION WAS SUBMITTED ON OR AFTER 2 MARCH 2004
SUB-PART A. GENERAL
A.1 Applicability
A.1.1 The Standards of Part IIIB are applicable in respect
of all aeroplanes designated in A.1.2 for which an application
for the issue of a type certificate is submitted to the
appropriate national authorities on or after 2 March 2004.
A.1.2 Except for those Standards and Recommended
Practices which specify a different applicability, the Standards
and Recommended Practices of Part IIIB shall apply to all
aeroplanes of over 5 700 kg maximum certificated take-off
mass intended for the carriage of passengers or cargo or mail
in international air navigation.
Note 1.— The aeroplanes described in A.1.2 are known in
some States as transport category aeroplanes.
Note 2.— The following Standards do not include
quantitative specifications comparable to those found in
national airworthiness codes. In accordance with 3.2.2 of
Part II, they are to be supplemented by national requirements
prepared by Contracting States.
A.1.3 The level of airworthiness defined by the appropriate
parts of the comprehensive and detailed national code
referred to in 3.2.2 of Part II for the aeroplanes designated in
A.1.2 shall be at least substantially equivalent to the overall
level intended by the broad Standards of Part IIIB.
A.1.4 Unless otherwise stated, the Standards apply to the
complete aeroplane including power-units, systems and equipment.
A.2 Operating limitations
A.2.1 Limiting conditions shall be established for the
aeroplane, its power-units and its equipment (see G.2).
Compliance with the Standards of Part IIIB shall be
established assuming that the aeroplane is operated within the
limitations specified. The limitations shall include a margin of
safety to render the likelihood of accidents arising therefrom
extremely remote.
Note.— Guidance material concerning the expression
“extremely remote” is contained in the Airworthiness Manual
(Doc 9760), Volume II, Part A.
A.2.2 Limiting ranges of mass, centre of gravity location,
load distribution, speeds, ambient air temperature and altitude
or pressure-altitude shall be established within which
compliance with all the pertinent Standards in Part IIIB is
shown.
Note 1.— The maximum operating mass and centre of
gravity limits may vary, for example, with each altitude and
with each separate operating condition, e.g. take-off, en route,
landing.
Note 2.— Maximum operating mass may be limited by the
application of Noise Certification Standards (see Annex 16,
Vol. I, and Annex 6, Parts I and II).
A.3 Unsafe features and characteristics
Under all anticipated operating conditions, the aeroplane shall
not possess any feature or characteristic that renders it unsafe.
A.4 Proof of compliance
Compliance with the appropriate airworthiness requirements
shall be based on evidence from tests, calculations or any
acceptable combination of tests and calculations, provided that
in each case the accuracy achieved will be such as to provide
reasonable assurance that the aeroplane, its components and
equipment comply with the requirements and are reliable and
function correctly under the anticipated operating conditions.
