An installation following Technical Standard Order standards does not require what?

An installation that adheres to Technical Standard Order (TSO) standards inherently implies that the equipment has already met specific performance criteria established by the FAA, which often streamlines the approval process for installations. When an installation is conducted following TSO standards, it typically does not require further individual approval from the FAA, as the equipment has already been vetted for compliance through the TSO approval process.

The other choices involve essential steps in the operation and maintenance of aircraft systems. FAA inspection may still be a requirement depending on the regulation governing the installation and use of the equipment. Documentation of the installation process is also critical for maintaining a record of compliance and ensuring that all procedures were followed correctly. Lastly, preflight checks are vital for ensuring the safety and airworthiness of the aircraft before flight. Therefore, the option stating no further approval for installation is indeed correct.
