## 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:

It has been revealed that the control surface balancing procedure in the * * * SAAB 2000 SRM (structural repair manual) * * * is incorrect.

* * * * *

Incorrect balance, outside the tolerance of the aileron control surface, may lead to vibrations that in [the] worst case can result in flutter.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
