                Subpart B_Loading, Unloading and Handling
 
Sec.  175.75  Quantity limitations and cargo location.


    (a) No person may carry on an aircraft a hazardous material except 
as permitted by this subchapter.
    (b) Except as otherwise provided in this subchapter, no person may 
carry a hazardous material in the cabin of a passenger-carrying aircraft 
or on the flight deck of any aircraft, and the hazardous material must 
be located in a place that is inaccessible to persons other than crew-
members. Hazardous materials may be carried in a main deck cargo 
compartment of a passenger aircraft provided that the compartment is 
inaccessible to passengers and that it meets all certification 
requirements for a Class B aircraft cargo compartment in 14 CFR 
25.857(b) or for a Class C aircraft cargo compartment in 14 CFR 
25.857(c). A package bearing a KEEP AWAY FROM HEAT handling marking must 
be protected from direct sunshine and stored in a cool and ventilated 
place, away from sources of heat.
    (c) For each package containing a hazardous material acceptable for 
carriage aboard passenger-carrying aircraft, no more than 25 kg (55 
pounds) net weight of hazardous material may

[[Page 732]]

be loaded in an inaccessible manner. Loaded in an inaccessible manner 
means cargo that is loaded in such a manner that a crew member or other 
authorized person cannot handle, and when size and weight permit, 
separate such packages from other cargo during flight. This includes 
materials loaded in a freight container in an accessible cargo 
compartment. In addition to the 25 kg limitation above, an additional 75 
kg (165 pounds) net weight of Division 2.2 (non-flammable compressed 
gas) may be loaded in an inaccessible manner. These requirements do not 
apply to Class 9 and ORM-D materials.
    (d) Each package containing a hazardous material acceptable only for 
cargo aircraft must be loaded in such a manner that a crew member or 
other authorized person can access, handle and when size and weight 
permit, separate such packages from other cargo during flight.
    (e) For cargo aircraft only, the requirements of paragraph (c) and 
(d) do not apply to the following hazardous materials:
    (1) Class 3--Packing Group III (that do not meet the definition of 
another hazard class), Division 6.1 (except those also labeled 
FLAMMABLE), Division 6.2, Class 7, Class 9 or ORM-D;
    (2) Division 2.2 in that an additional 75 kg (165 pounds) net weight 
of Division 2.2 material is authorized in inaccessible locations.
    (3) Packages of hazardous materials transported aboard a cargo 
aircraft, when other means of transportation are impracticable or not 
available, in accordance with procedures approved in writing by the FAA 
Regional or Field Security Office in the region where the operator is 
located.
    (4) Packages of hazardous materials carried on small, single pilot, 
cargo aircraft if:
    (i) No person is carried on the aircraft other than the pilot, an 
FAA inspector, the shipper or consignee of the material, a 
representative of the shipper or consignee so designated in writing, or 
a person necessary for handling the material;
    (ii) The pilot is provided with written instructions on the 
characteristics and proper handling of the materials; and
    (iii) Whenever a change of pilots occurs while the material is on 
board, the new pilot is briefed under a hand-to-hand signature service 
provided by the operator of the aircraft.
    (5) At a minimum, quantity limits and loading instructions in the 
following Quantity and Loading Tables must be followed to maintain 
acceptable quantity and loading between packages containing hazardous 
materials. The Quantity and Loading Tables are as follows:
