No. 08-01 59\nDear Mr. Tobin:\nThis is in response to your June 3,2008 letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171 - 1 80) applicable to cargo-only aircraft.\nSpecifically, you ask whether it is permissible to transport on cargo-only aircraft an unlimited\nnumber of packages authorized for transport on passenger aircraft if the packages are in a\nfreight container and accessible. You also ask how the limits on packages in inaccessible\ncargo locations apply.\nAs specified in 8 175. 75, there is no limit to the number of packages that are authorized\nonboard a cargo-only aircraft if packages are in a freight container and are accessible. Only\nthe packages that are inaccessible in a cargo compartment are subject to the limit of 25 kg per\ncompartment plus an additional 75 kg of Division 2.2 materials.\nI hope this information is helpful.\nSincerely,\nA9h2- 84) Susan Gorsky,\nRegulations Officer\nOffice of Hazardous Materials Standards\n\n<<<PAGE 2>>>\n\nJune 3, 2008\nEdward T.
