The Transportation Security Administration (TSA) recently released a proposed set of rules prohibiting flight of general aviation aircraft weighing more than 12,500 pounds unless they meet stringent new security program and pilot and passenger FBI clearance requirements. In light of that proposal, it is interesting to note that in July the agency said it is drafting proposed rules covering security of repair stations. The TSA audited hundreds of repair stations to evaluate the current level of security compliance and published the results in a document titled “Repair Station Security Measures” along with a “Security Inventory” that repair stations can use to evaluate their security measures. The TSA emphasized, “The security measures detailed in the checklist represent a listing of measures we have observed during our foreign repair station visits, and should not be construed as a preview of the pending security regulations.” The document does appear to provide insight into the direction of the TSA’s thinking on repair station security, and given the stringent nature of the proposed general aviation regulations, repair stations might want to prepare for an equally constraining proposal.
