## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A11 airplanes. This proposed AD was prompted by reports that, under certain combinations of airplane configuration and flight conditions, higher than anticipated temperatures could lead to an engine fire warning nuisance message. This proposed AD would require installation of Integrated Air Systems Controller (IASC) software version 5.0. The FAA is proposing this AD to address the unsafe condition on these products.
