Subject:     INFORMATION: Clarification of 49 CFR 175.85

From:    Edward T. Mazzullo, Director
Office of Hazardous Materials Standards

To:    William Wilkening, Manager

Dangerous Goods Program and Cargo Security

This is in response to your memorandum dated April 25, 2000, on whether a passenger-carrying aircraft can transport hazardous materials in a main deck cargo compartment that is certificated under 14 CFR 23.

49 CFR 175.85(a) states that "hazardous materials may be carried in a main deck cargo compartment of a passenger-aircraft provided that the compartment is inaccessible to passengers and that it meets all certification requirements for a Class B cargo compartment as provided in 14 CFR 25.857(b )." A main deck cargo compartment of a passenger-carrying airplane that has been certificated under 14 CFR part 23 is not likely to have been shown to meet the requirements of 14 CFR 25.857(b). In any event, reconfiguring a part 23 airplane to incorporate a Class B cargo compartment would likely be a major change in type design, which would require an amended or supplemental type certificate. In that case, there would be a record of a Federal Aviation Administration (FAA) approval, and the certification basis of that approval would state whether the change complies with 14 CFR 25.857(b). Therefore, hazardous materials may only be carried on

a main deck cargo compartment of a passenger-carrying aircraft that is certificated under 14 CFR Part 23 if there is a FAA amended or supplemental approval stating that the cargo compartment complies with 14 CFR 25.857(b).

I trust this satisfies your inquiry. This response was coordinated with the FAA's Office of the Chief Counsel.
