## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Saab AB, Support and Services Model SAAB 340B airplanes. This proposed AD was prompted by a report that the circuit breaker for the emergency cabin lighting tripped without fault in the system. This proposed AD would require replacing a certain circuit breaker with a part having a higher rating, 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.
