## Summary

We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. 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:

AD CF-2002-12 [which corresponds to FAA AD 2003-04-21, amendment 39-13070] mandated installation of revised overwing emergency exit placards showing that the exit door should be opened and disposed from a seated position. However, it was later discovered that the new placards illustrated an incorrect hand position for removal of the exit upper handle cover. These incorrect instructions could cause difficulty or delay when opening the overwing emergency exit.

As a result, the timely and safe evacuation of passengers and crew may be impeded. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
