Final answer:
The TSA has authority relative to the issuance or denial of certificates issued under FAR part 65. They conduct background checks to ensure that individuals who may pose a security risk are not granted certain aviation-related certificates.
Step-by-step explanation:
The TSA, or Transportation Security Administration, has authority relative to the issuance or denial of certificates issued under the provisions of FAR part 65. FAR, or Federal Aviation Regulations, is a set of rules and regulations established by the Federal Aviation Administration (FAA) that govern the aviation industry in the United States.
In the context of FAR part 65, the TSA is responsible for conducting background checks on individuals applying for certain aviation-related certificates, such as mechanics, repairmen, and flight instructors. The TSA's authority ensures that individuals who may pose a security risk are not granted these certificates.
For example, the TSA conducts security threat assessments for individuals applying for a mechanic certificate with airframe and powerplant ratings. If the TSA determines that an individual poses a security risk, they may deny the certificate application.
