FAA Issues AD on Socata TBM 700 Electrical System
The FAA has issued an Airworthiness Directive for the Socata TBM 700 electrical system.

The FAA has issued an Airworthiness Directive for the Socata TBM 700 electrical system. It is based upon a TBM700 operator report that as a result of a crewmember handling the standby compass lighting bulb cover in flight, both essential bus bars (ESS BUS 1 and ESS BUS 2) failed, leading to loss of a number of instruments and navigation systems. Investigation showed the electrical protection of some TBM 700s is insufficient to allow in-flight handling of the standby compass lighting cover when energized.
