The FAA opened its official comment period June 12 for an exemption to third class medical certificate regulations filed jointly by AOPA and the Experimental Aircraft Association (EAA). Supporters have only 20 days — until July 2 — to submit comments, according to a report at AOPA.org. “We urge those who have not commented on our exemption request to do so within the 20-day timeframe, because this request opens an important discussion about creating more possibilities to participate in aviation while maintaining a high safety standard,” said Robert Hackman, AOPA vice president of regulatory affairs. “Now is the time to make your voice heard on this important initiative.”
