The Federal Aviation Administration (FAA) grants the authority to operate on-demand, unscheduled air service in the form of Part 135 certificate. Air carriers authorized to operate with a 135 certificate vary from small single aircraft operators to large operators that often provide a network to move cargo to larger Part 121 air carriers. Many Part 135 operators offer critical passenger and cargo service to remote areas, providing a lifeline to populations that would not otherwise exist. All Part 135 air carriers are required to have a FAA approved hazardous materials (dangerous goods) program. This program must cover all aspects of the acceptance and transportation process, as well as training for all employees.
Regulations outlining the acceptance, handling, transport of hazardous materials and required training are found in the Hazardous Material Regulations (49 CFR Parts 100-185) and the ICAO Technical Instructions for the Safe Transportation of Dangerous Goods by Air. Compliance with the regulations is mandatory for all FAR 135 air carriers.
In addition to the regulations and guidelines issued by FAA Flight Standards, FAR 135 air carriers work closely with the FAA Office of Hazardous Materials Safety to develop, maintain and implement approved hazardous materials programs. Part 135 Single Pilot Operators are exempt from these requirements but are highly encouraged to develop and comply with an approved hazardous material program.
Hazardous Materials Aviation Safety Inspectors inspect Part 135 air carriers at multiple locations throughout the United States and its territories, and identify any regulatory violations, process and procedural findings, or program deficiencies.
