§ 175.33

Shipping paper and informa-

tion to the pilot-in-command. 

(a) When a hazardous material sub-

ject to the provisions of this sub-
chapter is carried in an aircraft, the 
operator of the aircraft must provide 
the pilot-in-command and the flight 
dispatcher or other ground support per-
sonnel with responsibilities for oper-

ational control of the aircraft with ac-
curate and legible written information 
(e.g., handwritten, printed, or elec-
tronic form) as early as practicable be-
fore departure of the aircraft, but in no 
case later than when the aircraft 
moves under its own power, which 
specifies at least the following: 

(1) The date of the flight; 
(2) The air waybill number (when 

issued); 

(3) The proper shipping name (the 

technical name(s) shown on the ship-
ping paper is not required), hazard 
class or division, subsidiary risk(s) cor-
responding to a required label(s), pack-
ing group and identification number of 
the material as specified in § 172.101 of 
this subchapter or the ICAO Technical 
Instructions (IBR, see § 171.7 of this 
subchapter). In the case of Class 1 ma-
terials, the compatibility group letter 
also must be shown.

(5) The exact loading location of the 

packages; 

(6) The net quantity or gross mass, as 

applicable, for each package except 
those containing Class 7 (radioactive) 
materials. For a shipment consisting of 
multiple packages containing haz-
ardous materials bearing the same 
proper shipping name and identifica-
tion number, only the total quantity 
and an indication of the quantity of 
the largest and smallest package at 
each loading location need to be pro-
vided. For consumer commodities, the 
information provided may be either the 
gross mass of each package or the aver-
age gross mass of the packages as 
shown on the shipping paper; 

(7) For Class 7 (radioactive) mate-

rials, the number of packages over-
packs or freight containers, their cat-
egory, transport index (if applicable),

age(s) is to be unloaded;

that a hazardous material is being car-
ried under terms of a special permit or 
under a State exemption as prescribed 
in the ICAO Technical Instructions 
(IBR, see § 171.7 of this subchapter); 

(11) The telephone number from 

whom the information contained in the 

861 

Pipeline and Haz. Matls. Safety Admin., DOT 

§ 175.33 

information to the pilot-in-command 
can be obtained. The aircraft operator 
must ensure the telephone number is 
monitored at all times the aircraft is 
in flight. The telephone number is not 
required to be placed on the informa-
tion to the pilot-in-command if the 
phone number is in a location in the 
cockpit available and known to the 
pilot-in-command; 

(12) For UN1845, Carbon dioxide, solid 

(dry ice), the information required by 
this paragraph (a) may be replaced by 
the UN number, proper shipping name, 
hazard class, total quantity in each 
cargo compartment aboard the air-
craft, and the airport at which the 
package(s) is to be unloaded; and 

(13)(i) For UN3480, Lithium ion bat-

teries, and UN3090, Lithium metal bat-
teries, the information required by 
paragraph (a) of this section may be re-
placed by the UN number, proper ship-
ping name, hazard class, total quantity 
at each specific loading location, the 
airport at which the package(s) is to be 
unloaded, and whether the package 
must be carried on cargo-only aircraft.

meet all of the requirements of this 
section. 

(iii) For UN3480, UN3481, UN3090, and 

UN3091 prepared in accordance with 
§ 173.185(c), except those prepared in ac-
cordance with § 173.185(c)(5), are not re-
quired to appear on the information to 
the pilot-in-command. 

(b)(1) The information provided to 

the pilot-in-command must also in-
clude a signed confirmation or some 
other indication from the person re-
sponsible for loading the aircraft that 
there was no evidence of any damage to 
or leakage from the packages or any 
leakage from the unit load devices 
loaded on the aircraft; 

(2) The information to the pilot-in- 

command and the emergency response 
information required by subpart G of 
part 172 of this subchapter shall be 
readily available to the pilot-in-com-
mand and flight dispatcher during 
flight. 

(3) The pilot-in-command must indi-

cate in writing (e.g., handwritten, 
printed, or electronic form) that the in-
formation to the pilot-in-command has 
been received. 

(c) The aircraft operator must— 
(1) 

For shipping papers. 

(i) Ensure a 

copy of the shipping paper required by 
§ 175.30(a)(2) accompanies the shipment 
it covers during transportation aboard 
the aircraft. 

(ii) Retain a copy of the shipping 

paper required by § 175.30(a)(2) or an 
electronic image thereof, that is acces-
sible at or through its principal place 
of business and must make the ship-
ping paper available, upon request, to 
an authorized official of a federal, 
state, or local government agency at 
reasonable times and locations. For a 
hazardous waste, each shipping paper 
copy must be retained for three years 
after the material is accepted by the 
initial carrier. For all other hazardous 
materials, each shipping paper copy 
must be retained by the operator for 
one year after the material is accepted 
by the initial carrier. Each shipping 
paper copy must include the date of ac-
ceptance by the carrier. The date on 
the shipping paper may be the date a 
shipper notifies the air carrier that a 
shipment is ready for transportation, 
as indicated on the air waybill or bill 
of lading, as an alternative to the date 
the shipment is picked up or accepted 
by the carrier. Only an initial carrier 
must receive and retain a copy of the 
shipper’s certification, as required by 
§ 172.204 of this subchapter. 

(2) 

For information to the pilot-in-com-

mand. 

Retain for 90 days at the airport 

of departure or the operator’s principal 
place of business. 

(3) Have the shipping paper and infor-

mation to the pilot-in-command read-
ily accessible at the airport of depar-
ture and the intended airport of arrival 
for the duration of the flight. 

(4) Make available, upon request, to 

an authorized official of a Federal, 
State, or local government agency 
(which includes emergency responders) 
at reasonable times and locations, the 
documents or information required to 
be retained by this paragraph. In the 
event of a reportable incident, as de-
fined in § 171.15 of this subchapter, the 

862 

49 CFR Ch. I (10–1–23 Edition) 

§ 175.34 

aircraft operator must make imme-
diately available to an authorized offi-
cial of a Federal, State, or local gov-
ernment agency (which includes emer-
gency responders), the documents or 
information required to be retained by 
this paragraph (c). 

(5) Specify the personnel to be pro-

vided the information required by para-
graph (a) of this section in their oper-
ations manual and/or other appropriate 
manuals. 

(d) The information required by para-

graph (a) of this section and the ship-
ping paper required by (c)(1) of this sec-
tion may be combined into one docu-
ment.
