## 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:

Two incidents have occurred due to the lack of visibility on the Primary Flight Display (PFD) of the Traffic Alert and Collision Avoidance System (TCAS) indications.

* * * * * We are issuing this AD to prevent possible mid-air collisions due to lack of visibility of TCAS indications on the PFD. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
