Unsafe Condition
The control surface balancing procedure in the web and CD/DVD versions of the SAAB 2000 SRM Chapter 51-60-00 contains an incorrect calculation formula, where multiplication was replaced with addition. This could result in aileron control surface balance outside the allowed tolerance, leading to vibrations and potentially flutter.
