The FAA has issued an Emergency Airworthiness Directive # 2020-18-51 on the SAI 340 A P/N 306171-20 and the Bendix/King KI 300 P/N 306171-10. Sandia is currently working on a solution to this issue. When one is found units will be updated at no charge. In the meantime, all SAI 340A standby attitude indicators should be placarded FOR DAY TIME VFR USE ONLY.
At this time we do not have a schedule for the fix but will post updates on our web site at www.sandia.aero. We sincerely apologize for this inconvenience.
