Aren’t rules like this usually changed by regulators, after extensive examination of data: fatigue, motor skills and aging, etc? How often do safety regulations, particularity in aviation, get changed by a legislator’s bill? The only thing I could see is a bill that would mandate the FAA to examine raising the age beyond 65. At that point the work would begin (probably several years) and then we’d get a recommendation. Anything can happen but I don’t see this going past Grahams’ desk.
