## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from 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:

Analyses of in-service reports revealed that in case of failure of the wings anti-ice valve, indications of untimely anti-icing with the wings anti-ice selector on "OFF'' or of insufficient anti-icing with the wings anti-ice selector on "AUTO'' might not be properly displayed to the flight crew. It may result, on ground, in potential structural damages due to a leading edge overheat, or in-flight, in an insufficient anti-ice power. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
