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) issued 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:
Following Safety Alert No. SA-006, issued by the National Transportation Safety Board (NTSB) on aircraft icing, it was impossible to demonstrate that the aircraft can safely takeoff when contaminated by frost, ice, snow, or slush, and fly into icing conditions.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
