Importance to Members

The U.S. Department of Transportation, Title 49 CFR, governs and is the regulatory authority for the transportation of all hazardous materials in commerce, on public highways and waterways and in the airspace of the United States. This includes the regulatory guidance of transportation of such materials by private aircraft, air taxi/charter, and airline passengers and all cargo operations under FAR Parts 91, 121, and 135.

The transportation of any defined hazardous material by private general aviation aircraft, while not totally prohibited (note that many materials are, in fact, prohibited), does carry certain risks and should not be considered, unless absolutely necessary.

Quick Points

  • AmmunitionGasoline – Aviation and auto fuel may be transported by air in certain quantities and containers.
  • Ammunition – Small-arms ammunition for personal use carried by a crewmember or passenger in his/her baggage is permitted if securely packed in fiber, wood or metal boxes, or other packagings specifically designed to carry small amounts of ammunition.
  • Fireworks – Are prohibited from being transported by air as they are classed as explosives and pyrotechnic devices.

As always, feel free to call AOPA's Pilot Information Center at 800/USA-AOPA (872-2672) with questions.

Overview

FAR Parts 121 and 135 have specific training requirements for crews to complete before carrying hazardous materials, and crews must maintain this training annually as long as they transport the materials. Part 91 operators are not required to be trained and certified under the 49 CFR regulations; however, the transportation of hazardous materials in general aviation aircraft is confined to excepted and limited quantities of materials approved and permitted to be shipped by air.

Part 175 – Carriage by Aircraft

The regulations concerning transportation of hazardous materials specifically by any aircraft are found in  49 CFR Part 175. The table of contents is reproduced below to give an outline of what is contained in that part. The information displayed is not a complete listing of the regulations, but instead a list of points thought by the AOPA to be important for General Aviation.

Sec. 175.5 Applicability

This part applies to the acceptance for transportation, loading and transportation of hazardous materials in any aircraft in the United States and in aircraft of United States registry anywhere in air commerce.

Sec. 175.10 Exceptions

  • Hazardous SignsThis subchapter does not apply to:
    • Aviation fuel and oil in tanks that are in compliance with the installation provisions of 14 CFR, chapter 1.
    • Hazardous materials required aboard an aircraft in accordance with the applicable airworthiness requirements and operating regulations. Unless otherwise approved by the Associate Administrator, items of replacement for such hazardous materials must be transported in accordance with this subchapter except that—
      • In place of the required packaging, packaging’s specially designed for the transport of aircraft spares and supplies may be used, provided such packaging provide at least an equivalent level of protection to those that would be required by this subchapter;

    • Smoke grenades, flares, and pyrotechnic devices affixed to aircraft
    • Carbon dioxide, solid (dry ice) when:
      • In quantities not exceeding 2.3 kg (5.07 pounds) per package packed as prescribed by Sec. 173.217 of this subchapter and used as a refrigerant for the contents of the package. The package must be marked with the name of the contents being cooled, the net weight of the dry ice or an indication that the net weight is 2.3 kg (5.07 pounds) or less, and also marked "Carbon Dioxide, Solid" or "Dry Ice";
      • Intended for use in food and beverage service aboard aircraft; or
      • In quantities not exceeding 2 kg (4.4 pounds) per passenger when used to pack perishables in carry-on baggage provided the package permits the release of carbon dioxide gas.

Sec. 175.75 Quantity Limitations aboard Aircraft

  • Except as provided in Sec. 175.85(c)(3), no person may carry on an aircraft:
    • A hazardous material except as permitted by this subchapter;
    • More than 25 kg (55 pounds) net weight of hazardous material (and in addition thereto, 75 kg (165 pounds) net weight of Division 2.2 (non-flammable compressed gas) materials permitted to be carried aboard passenger-carrying aircraft:
      • In an inaccessible cargo compartment,
      • In any freight container within an accessible cargo compartment, or
      • In any accessible cargo compartment in a cargo aircraft only in a manner that makes it inaccessible unless in a freight container;
    • Packages containing Class 7 (radioactive) materials when their combined transport index number (determined by adding together the transport index numbers shown on the labels of the individual packages and/or overpacks):
      • In passenger carrying aircraft, exceeds 50.0 or, for any single package, exceeds 3.0, or
      • In cargo aircraft only, exceeds 200.00 (for fissile Class 7 (radioactive) materials, see Sec. 175.702(b)(2)(iv)) or, for any single package, exceeds 10.0.
  • No limitation applies to the number of packages of Class 9 (miscellaneous hazardous) materials, or ORM-D materials aboard an aircraft.

Even though a private or general aviation business aircraft operating under Part 91 is, in fact, a private aircraft, the movement of this aircraft at public use airports, parking at public FBOs, and flying in the national airspace system, exposes the general public to the dangers of these materials. Fire fighters, rescue personnel, and others are at unnecessary risk when hazardous materials are transported and in aircraft not in compliance with the regulations. In the event of any aircraft incident or accident, there can be serious dangers to aircraft, crew, passengers and the general public. Therefore, compliance with the regulations is required.

Note: For non-pressurized general aviation aircraft flying at 9,000 feet msl, the pressure inside a plastic bottle/container or aerosol will be greater than at sea level. Therefore the possibility of an in-flight accident is greater. Please be guided accordingly, and do not transport excessive quantities beyond what the regulation allows.

Packaging of Hazardous Materials

Hazardous TeamUnless the mandatory training required by  49 CFR 172.704 for packaging hazardous material has been received, do not attempt to pack any hazardous material for transport by aircraft. This includes, but is not limited to, forwarding any hazardous material by United Parcel Service air or ground or FedEx by air or ground transportation. Use an approved hazardous material packaging firm.

Mandatory training requirements for Part 135 certificate holders are listed in Subpart K of 135.501, 503, 505, and 507, and mandatory training requirements for Part 121 certificate holders are listed in Subpart Z of  121.1001, 1003, 1005, and 1007.
