No.: 09-0254\nDear Mr. Uehara:\nThis responds to your E-mail dated October 28, 2009 requesting clarification of the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the loading of\nhazardous materials in aircraft. Specifically, you ask ifthere are specific quantity limits for\npackages of hazardous materials bearing a \"Cargo Aircraft Only\" label when loaded in the\nsame Class C cargo compartment with packages of hazardous materials that are eligible for\ncarriage on passenger-carrying aircraft.\nThe answer is yes. For each package containing a hazardous material acceptable for carriage\naboard passenger-carrying aircraft, no more than 25 kg (55 pounds) net weight ofhazardous\nmaterial may be loaded in an inaccessible manner. In addition to the 25 kg limitation above,\nan additional 75 kg (165 pounds) net weight ofDivision 2.2 (non-flammable compressed gas)\nmay be loaded in the same compartment. See § 175.75(c). \"Loaded in an inaccessible\nmanner\" means cargo loaded in a manner that precludes a crew member or other authorized\nperson from handling, and when size and weight permit, separating such packages from other\ncargo during flight. You state that the Class C compartment of your aircraft is inaccessible to\ncrew members. Thus, you are limited to 25 kg of hazardous material that is acceptable for\ncarriage aboard passenger-carrying aircraft, and in addition 75 kg of division 2.2 (nonflammable\ncompressed gas) in the same Class C compartment.\nPackages containing hazardous materials that are marked \"Cargo Aircraft Only\" are\nconsidered to be \"accessible\" for the purposes of § 175.75 when loaded in a cargo\n\n<<>>\n\ncompartment certified by FAA as a Class C cargo compartment as defined in 14 CFR\n25.857(c). See § 175.75(f). Thus, there is \"no limit\" to the quantity ofcargo aircraft only\npackages that may be loaded in a Class C cargo compartment.\nI hope this answers your inquiry.\nSincerely,\natk(o~\nCharles E.
