The FAA will begin formal rulemaking to consider whether to allow private pilots to use a driver’s license in lieu of an FAA medical certificate in some circumstances, the agency announced yesterday. The announcement follows a joint petition by AOPA and the Experimental Aircraft Association to the FAA to expand the third-class medical exemption, as well as proposed legislation, the General Aviation Pilot Protection Act (GAPPA), that is currently making its way through both the House and Senate.
