FARs
In order to implement, and enforce (let alone enforce in anything approaching a systematic way) post-accident testing regimen on foreign-certificated air transport carrier crews, would there not need to be some emendation, or alteration or revision or amendment, to the governing international agreements, such as the Chicago Convention (1944) or others? Alternatively, consider a hypothetical in which mishaps substantially similar or parallel in their essential probable cause roots occur with significant frequency (that is, lack of hand flying, horribly botched CAVOK approach, insufficient time in type, cockpit culture of obsequiousness - some or all of these), all foreign-certificated air carriers. Would Congress pass, and would the president sign, legislation creating (or expanding, if it is said to exist already) federal jurisdiction for law enforcement purposes relative to safety of air transport operations? Staff the NTSB Go Team with federal Marshals and the civilian equivalent of Judge Advocates. Require every airport with an FAA facility to enter into a MOU (Memorandum of Understanding) requiring local law enforcement to impound the crew until chain of custody testing can be federally overseen and administered. They fly into U S of A airspace, swear 'em into the union, test 'em, without fail, just like we do to our own. I could write this legislation in a week; getting it passed, and getting the president to sign it....."Priceless" --
