Reference No. 15-0016

Dear Mr. Wentz:

This responds to your December 22, 2014 letter requesting clarification on transporting Class 7 materials under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) aboard passenger aircraft. Section 175.700(a) prescribes that no person may carry any Class 7 materials aboard a passenger-carrying aircraft unless that material is intended for use in, or incident to research, medical diagnosis or treatment. Regardless of its intended use, no person may carry a Type B(M) package aboard a passenger-carrying aircraft, a vented Type B(M) package aboard any aircraft, or a liquid pyrophoric Class 7 material aboard any aircraft.

You ask if a passenger aircraft operator may transport Type B(U) packages containing vials of liquid radioactive Molybdenum 99 (Mo99) and the return of empty Type B(U) containers as Type A packages, provided the requirements applicable to radioactive materials incident to research, medical diagnosis or treatment are satisfied.

The answer to your question is yes. Radioactive materials in Type B(U) and Type A packages that do not exceed a transport index of 3.0 and intended for use in or incident to research, medical diagnosis, or treatment may be transported on board passenger-carrying aircraft in accordance with §§ 173.448(f) and 175.700(a).

I trust this information is helpful. If you have further questions, please do not hesitate to contact this office.

Sincerely,

 

Duane A. Pfund
