Who issues a Technical Standard Order (TSO)?

A Technical Standard Order (TSO) is issued by the FAA Administrator. This process typically involves establishing specific performance standards for certain materials, parts, or appliances used in aircraft and their associated systems. TSOs are important as they help ensure that products meet safety and performance criteria necessary for aviation operations.

The issuance of a TSO is essential not only for the manufacturers of aviation products but also for maintaining the overall safety and reliability of aircraft in operation. When a manufacturer complies with a TSO, it demonstrates that their product has met the established standards, leading to increased trust from regulatory bodies, operators, and the flying public alike.

In contrast, the other entities listed do not have the authority to issue TSOs. The United States Department of Transportation oversees many aspects of transportation policy but does not specifically issue TSOs. The Aircraft Manufacturers Association may advocate for manufacturers' interests but does not have regulatory power in terms of issuing TSOs. The National Transportation Safety Board primarily investigates transportation accidents and promotes safety, but it does not engage in the issuance of TSOs. Hence, the FAA Administrator is the correct authority involved in this process.
