3 checkride failures shouldn't be acceptable for a professional pilot. I'm sure a lot of guys don't agree with that for whatever reason, but the fact of the matter is standards must be maintained. 1 failure is understandable, 2 is unfortunate, by failure number 3 you should be starting to get the hint that you're just not cut out to fly at a professional level. There are no excuses. If you had other things going on in your life at the time that led to you failing so many checkrides, then you should have put your training off until such time that you could put your full focus and energy into attaining the correct standard.

Too many people think that attaining a professional flying licence is just a case of jumping through hoops. It isn't. There is no barrier to entry these days other than one's ability to pass checkrides and later on, the airline interview.

The standard to pass these checkrides isn't all that high. If you can't meet the standard on three different occasions, then you shouldn't be flying people around for money. Of course failures happen occasionally, but three failures should be a major alarm bell that should prompt you to think that maybe you just aren't cut out for professional flying.
