Notice of proposed rulemaking NPRM.

ACTION:

The FAA proposes to adopt a new airworthiness directive AD for all ATRGIE Avions de Transport Regional Model ATR42500 and ATR72212A

This proposed AD would require replacing affected GPS SBAS receivers with new, improved receivers, as specified in a European Union Aviation Safety Agency EASA AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by August 23, 2021.
