Technical Standard Orders (TSO) Catalog

Technical Standard Order parts refer to parts adhering to the minimum performance standards set forth by the Federal Aviation Administration (FAA) for materials, parts, processes, and appliances found in civil aircraft. Any part of an aircraft must have authorization that it meets these standards in order for the aircraft to be considered airworthy. The most basic authorization is called a type certificate. A secondary certification, called a supplementary type certificate, is given to aircraft that have undergone major structural modifications, additions, or repairs. For example, if a passenger aircraft is converted into a freight aircraft, a supplementary type certificate must be issued before the aircraft is able to take flight.

TSO Aviation standards are the highest level of authorization and serve as a standardized criteria for manufacturers to adhere to. For a part of an aircraft to be TSO certified, it must meet standards relating to electrical, safety, and environmental performance. The electrical standards that must be followed are capacity and power ratings at different temperatures, charge and discharge characteristics, life cycle testing, charge acceptance, shelf life, and more. Safety criteria includes short circuits, insulation resistance, dielectric strength, explosion containment, and general strength of parts. Lastly, TSO certified parts must be environmentally efficient at different altitudes, humidities, and be resistant to fluid and fungal contamination.
