Note on status of age 60 rule
A 1993 study performed for the FAA by Hilton Systems, Inc. concluded that empirical data provided no support for the hypothesis that pilots approaching age 60 had increased accident rates. The FAA held a public hearing, and considered a petition for a new rule that would modify the mandatory age-60 retirement rule. In the end it decided that even state-of-the-art testing cannot screen out potentially risky pilots and decided not to change the rule. That decision was upheld in Prof. Pilots Federation v. FAA, 118 F.3d 758 (D.C. Cir. 1997).
