Case in point, the FAA post-Colgan. But does 1500hrs maketh the pilot, probably not. That's a different argument.
I posted the following answer in another thread, but copy it below.
The Colgan captain had around 3,300 hours and the first officer 2,200 hours. On Air France the captain had 11,000 hours and the two f/o's 6,600 and 3,000 hours respectively. Not a single one of these pilots would have been precluded by a 1500 hour minimum tariff. The Colgan captain had a history of numerous failed check rides during his training and was regularly commuting some 1200 miles from his home in Florida. The first officer was also regularly commuting 3000 miles from her home in Seattle. Fatigue was cited as a likely contributory factor.
