Cooking the books is also illegal correct? So while it may be difficult to detect, it still is the FAA's responsibility to root out organizations that aren't following the rules and be absolutely ruthless in punishing falsification of records(which shows intent, not just naiveté). Creative fraud calls for creative detection solutions. Maybe the company is required to have their scheduling system submit the schedules ahead of time and then have an FAA system cross reference the actual flight information against that.
That is my point though. If it looks legal, what actions does a governing body have to go beyond that? Cooking the books is illegal but it is hard to prove that it is even being done. The company is responsible for self certifying lots and lots of things. Did that oil change get done? Sure it did, says so right here... Do you keep your crews on call 24/7? Absolutely not, says so right here...
Like I said, it takes an accident to expose this stuff. When they can test the oil, look at part numbers of failed components, review CVR and FDR data, open the books further than the top page, interview employees etc. I posted an NTSB report in the general section of a pilot that took off with one engine inop on a 2 engine jet, because he was gonna compression start the other one in the air, and the "FO" was a non rated seat warmer. How many times did that plane fly illegally before it took an accident to expose that crap?
I hate to keep bringing up the Ohio Hawker crash as it is still fresh and no reports have been made, but when you have a perfectly good airplane with 2 pilots on board, go below minimums and crash on an approach, you start to wonder about the other things like fatigue, SOP etc. Stuff like that happens every single day, and the FAA has no control over it. It will only change if they can prove pilot error and can pin fault on the company for something related to the accident. Lets hope that if that is the case, that the FAA does take action for it.
The stuff my first charter company pulled ( left in 2013) would blow your freaking minds. They employed captains that had no business being behind the wheel, multiple checkride failures, on call, terrible mx, fishy money handling (they had the amex accounts foreclosed, and our credit cards would routinely get denied on the road), no SOP, no standards in for the cockpit or anywhere else for that matter. One of the captains failed his initial, and his recurrent twice in one airplane, so he was placed back in the airplane he had more experience in. Think the FAA wouldn't like to know why a 63 year old man that has 3 checkride failures in 6 months in one airplane, is allowed to command anything other than a toaster? I could go on and on and on, and the FAA is none the wiser.
