Dear Ms. Abdul:

This is in response to your letter dated February 22, 2000 regarding the transportation of compressed oxygen cylinders aboard aircraft.  Specifically, you ask if partially filled oxygen cylinders may be transported aboard an aircraft in an ATA Specification 300 outer packaging.

The Hazardous Materials Regulations (49 CFR Parts 171-180) do not specify a minimal fill limit when transporting cylinders of compressed gas, including compressed oxygen.  Therefore, it is the opinion of this Office that partially filled cylinders of compressed oxygen may be transported aboard an aircraft in an ATA 300 Specification, outer packaging.

I hope this satisfies your request.
