A Technical Standard Order, or TSO, is a minimum performance standard met by specific materials, parts, and appliances that find use on civil aircraft. Through TSO Authorization, a manufacturer is approved for the design and production of various materials, parts, or appliances. Despite this, it is important to understand that TSO Authorization does not allow for the particular item to be installed and used on an aircraft. Simply, it is the approval for the applicant to manufacture the item and proof that the item meets a specific TSO.

To receive a TSO Authorization, one must show that the particular component meets the specific airworthiness requirements of the particular aircraft model in question on a certificate basis. For the actual installation, a different FAA approval must be applied for and approved.  TSO Authorizations can also be canceled or withdrawn, both meaning different things. A “Canceled TSO” is simply one that has been rendered inactive, meaning that the FAA will not provide new authorizations. This, however, does not affect any TSO Authorizations that were obtained prior to the cancellation. Withdrawn TSOs, on the other hand, are those that can still be produced but cannot have authorization to a particular TSO revision level. If the TSO is withdrawn for any reason, the articles cannot be manufactured and labeled as TSO parts.
