Subpart C—Specific Regulations 

Applicable According to 
Classification of Material 

§ 175.310

Transportation of flammable 

liquid fuel; aircraft only means of 
transportation. 

(a) When other means of transpor-

tation are impracticable, flammable 
liquid fuels may be carried on certain 
passenger and cargo aircraft as pro-
vided in this section, without regard to 
the packaging references and quantity 
limits listed in Columns 7, 8 and 9 of 
the § 172.101 Hazardous Materials Table. 
All requirements of this subchapter 
that are not specifically covered in this 
section continue to apply to shipments 
made under the provisions of this sec-
tion. For purposes of this section ‘‘im-
practicable’’ means transportation is 
not physically possible or cannot be 
performed by routine and frequent 
means of other transportation, due to 
extenuating circumstances. Extenu-
ating circumstances include: condi-
tions precluding highway or water 
transportation, such as a frozen vessel 
route; road closures due to cata-
strophic weather or volcanic activity; 
or a declared state of emergency. The 
desire for expedience of a shipper, car-
rier, or consignor, is not relevant in de-
termining whether other means of 
transportation are impracticable. The 
stowage requirements of § 175.75(a) do 
not apply to a person operating an air-
craft under the provisions of this sec-
tion which, because of its size and con-

figuration, makes it impossible to com-
ply. 

(b) A small passenger-carrying air-

craft operated entirely within the 
State of Alaska or into a remote area, 
in other than scheduled passenger oper-
ations, may carry up to 76 L (20 gal-
lons) of flammable liquid fuel (in Pack-
ing Group II or Packing Group III), 
when: 

(1) The flight is necessary to meet 

the needs of a passenger; and 

(2) The fuel is carried in one of the 

following types of containers: 

(i) Strong tight metal containers of 

not more than 20 L (5.3 gallons) capac-
ity, each packed inside a UN 4G fiber-
board box, at the Packing Group II per-
formance level, or each packed inside a 
UN 4C1 wooden box, at the Packing 
Group II performance level; 

(ii) Airtight, leakproof, inside con-

tainers of not more than 40 L (11 gal-
lons) capacity and of at least 28-gauge 
metal, each packed inside a UN 4C1 
wooden box, at the Packing Group II 
performance level; 

(iii) UN 1A1 steel drums, at the Pack-

ing Group I or II performance level, of 
not more than 20 L (5.3 gallons) capac-
ity; or 

(iv) In fuel tanks attached to flam-

mable liquid fuel powered equipment 
under the following conditions: 

(A) Each piece of equipment is se-

cured in an upright position; 

(B) Each fuel tank is filled in a man-

ner that will preclude spillage of fuel 
during loading, unloading, and trans-
portation; and 

(C) Fueling and refueling of the 

equipment is prohibited in or on the 
aircraft. 

(3) In the case of a passenger-car-

rying helicopter, the fuel or fueled 
equipment must be carried on external 
cargo racks or slings. 

(c) Flammable liquid fuels may be 

carried on a cargo aircraft, subject to 
the following conditions: 

(1)(i) The flammable liquid fuel is in 

Packing Group II or Packing Group III 
except as indicated in paragraph 
(c)(1)(iv) of this section; 

(ii) The fuel is carried in packagings 

authorized in paragraph (b) of this sec-
tion; 

(iii) The fuel is carried in metal 

drums (UN 1A1, 1B1, 1N1) authorized for
