Abstract
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Model 390 airplanes. This AD requires you to modify the aft power distribution box and the aft ram air duct. This AD is the result of reports of two incidents involving temporary loss of all attitude display information. The actions specified by this AD are intended to prevent moisture from entering the aft power distribution box through the aft ram air duct, which could result in electrical power failure. Such failure could lead to loss of all attitude display information during flight.
