Dear Mr. Uehara:
This responds to your E-mail dated October 28, 2009 requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the loading of hazardous materials in aircraft. Specifically, you ask if there are specific quantity limits for packages of hazardous materials bearing a "Cargo Aircraft Only" label when loaded in the same Class C cargo compartment with packages of hazardous materials that are eligible for carriage on passenger-carrying aircraft.
The answer is yes. 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 be loaded in an inaccessible manner. 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 the same compartment. See § 175.75(c). "Loaded in an inaccessible manner" means cargo loaded in a manner that precludes a crew member or other authorized person from handling, and when size and weight permit, separating such packages from other cargo during flight. You state that the Class C compartment of your aircraft is inaccessible to crew members. Thus, you are limited to 25 kg of hazardous material that is acceptable for carriage aboard passenger-carrying aircraft, and in addition 75 kg of division 2.2 (non-flammable compressed gas) in the same Class C compartment.
Packages containing hazardous materials that are marked "Cargo Aircraft Only" are considered to be "accessible" for the purposes of § 175.75 when loaded in a cargo compartment certified by FAA as a Class C cargo compartment as defined in 14 CFR 25.857(c). See § 175.75(f). Thus, there is "no limit" to the quantity of cargo aircraft only packages that may be loaded in a Class C cargo compartment.
I hope this answers your inquiry.
Sincerely,
Charles E. Betts
