Read CKA Peavley's interview. He busted him at Atlas on his 767 type rating ride. The checkride started out bad, Peavley thought perhaps due to nerves with the FAA observing, but it got worse. He finally stopped the ride early and the FO was stunned. There's a complete disconnect when you think your performance is acceptable and the CKA stops the ride because it's completely unacceptable. Peavley was asked what he thought - "I thought he should be in a different profession."
When it appears that you have more 121 busts than 'passed on first attempts' the industry needs to do a better job documenting this. Maybe a national database for busts that employers can access?
