rials shipments.

§ 175.8

Exceptions for operator equip-

ment and items of replacement. 

(a) 

Operator equipment. 

This sub-

chapter does not apply to— 

(1) Aviation fuel and oil in tanks that 

are in compliance with the installation 
provisions of 14 CFR, chapter 1. 

(2) Hazardous materials required 

aboard an aircraft in accordance with 
the applicable airworthiness require-
ments and operating regulations. Items 
of replacement for such materials must 
be transported in accordance with 
paragraph (a)(3) of this section. 

(3) Items of replacement (company 

material (COMAT)) for hazardous ma-
terials described in paragraph (a)(2) of 
this section must be transported in ac-
cordance with this subchapter. When 
an operator transports its own replace-
ment items described in paragraph 
(a)(2), the following exceptions apply: 

(i) In place of required packagings, 

packagings specifically designed for 
the items of replacement may be used, 
provided such packagings provide at 
least an equivalent level of protection 
to those that would be required by this 
subchapter. 

(ii) Aircraft batteries are not subject 

to quantity limitations such as those 
provided in § 172.101 or § 175.75(c) of this 
subchapter. 

(4) Unless otherwise addressed by 

FAA regulation or policy (e.g. Advisory 
Circular), hazardous materials used by 
the operator aboard the aircraft, when 
approved by the Administrator of the 
Federal Aviation Administration. 

(b) 

Other operator exceptions. 

This sub-

chapter does not apply to— 

(1) Oxygen, or any hazardous mate-

rial used for the generation of oxygen, 

for medical use by a passenger, which 
is furnished by the aircraft operator in 
accordance with 14 CFR 121.574, 125.219, 
or 135.91. For the purposes of this para-
graph (b)(1), an aircraft operator that 
does not hold a certificate under 14 
CFR parts 121, 125, or 135 may apply 
this exception in conformance with 14 
CFR 121.574, 125.219, or 135.91 in the 
same manner as required for a certifi-
cate holder. See § 175.501 for additional 
requirements applicable to the stowage 
of oxygen. 

(2) Dry ice (carbon dioxide, solid) in-

tended for use by the operator in food 
and beverage service aboard the air-
craft. 

(3) Aerosols of Division 2.2 only (for 

dispensing of food products), alcoholic 
beverages, colognes, liquefied gas light-
ers, perfumes, and portable electronic 
devices containing lithium cells or bat-
teries that meet the requirements of 
§ 175.10(a)(18) carried aboard a pas-
senger-carrying aircraft by the oper-
ator for use or sale on that specific air-
craft. A liquefied gas lighter design 
must be examined and successfully 
tested by a person or agency author-
ized by the Associate Administrator. 

(4) A tire assembly with a serviceable 

tire, provided the tire is not inflated to 
a gauge pressure exceeding the max-
imum rated pressure for that tire, and 
the tire (including valve assemblies) is 
protected from damage during trans-
port. A tire or tire assembly which is 
unserviceable or damaged is forbidden 
from air transport; however, a damaged 
tire is not subject to the requirements 
of this subchapter if it contains no ma-
terial meeting the definition of a haz-
ardous material (e.g., Division 2.2). 

(5) Alcohol-based hand sanitizers and 

alcohol-based cleaning products that 
are accessible to crewmembers in the 
passenger cabin during the flight or se-
ries of flights for the purposes of pas-
senger and crew hygiene. Conditions 
for the carriage and use must be de-
scribed in an operations manual and/or 
other appropriate manuals.
