Notice of proposed rulemaking (NPRM).

The FAA proposes to adopt a new airworthiness directive (AD) for all ASI Aviation (type certificate previously held by Reims Aviation S.A.) Model F406 airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as failure of a circuit breaker (CB) switch. This proposed AD would require replacing certain CB switches and establishing a life limit for the CB switches. The FAA is proposing this AD to address the unsafe condition on these products.
