## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109S and AW109SP helicopters. This proposed AD was prompted by the discovery that rubber protection of certain electrical wiring had not been installed in the baggage avionics bay during production. This proposed AD would require installing protective rubber borders on the edge of the baggage avionics bay frames, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
