Dear Mr. Hagenmayer:
This responds to your letter regarding the quantity limitation
and package containment requirements for hazardous materials
transported by cargo-only aircraft under the Hazardous Materials
Regulations (HMR; 49 CER Parts 171-180). Your questions are
paraphrased and answered as follows:

Dear Mr. Mazzullo:
I am writing to you for clarification of 49 CFR, Subpart B, 175.75(a)(2)(iii) and 171.8 "Freight
Container".
Is it acceptable to carry 25 kg net weight of hazardous materials and in addition thereto, 75 kg net
Question 1:
weight of Division 2.2 (non-flammable compressed gas) in each freight container loaded on the main
deck of a cargo aircraft's main deck? The cargo aircraft's main deck is accessible to the flight crew
through an access door in the 9g bulkhead. Based on the definition of a "freight container" in 171.8,
I assume that the answer is yes.
Does the definition of a "freight container" also include aircruft pallet/net combination and aircraft
Question 2:
pailet/cargo strap combinations providing their volume is 64 cubic feet or more? I assume that the
answer is yes because aircraft pallets used in combination with nets or cargo straps are designed and
constructed to permit being lifted with its contents and intended primarily for containment of
packages (in unit form) during transportation.
If my two assumptions above are incorrect would it be possible to discuss this matter with someone
on the telephone so I can better understand the intent of these rogulations. My telephone number is
419-867-9911 × 2241 and my fax is 419-867-0138. I look foniard to your response.
