25: Crew Seat Armrest Stop Pin – Engineering has approved the use of a solid pin to provide a more robust installation; however, it is still recommended that the armrest be folded up and out the way while entering or existing the crew position and not used as a prop.
28: Fuel Heated Vent Outer Coating – The King Air fuel heated vent outer coating is subject to elements and airstream causing the outer coating to erode with time.

The fuel liner is installed with pop rivets, and the rivets and seams are covered with protective tape to protect the fuel bladder. The part number of the tape is PPP-T60E, and the part number of the rivets is AD42BS. These parts are available from Textron Aviation Parts and Distribution.

The FMS Desktop Trainer software is based on the Fusion phase 3 B350 and provides a near realtime, Windows simulation environment.
36: Pneumatic Pressure Indication Increases on Ascent – Reports of pneumatic pressure indication increasing when the airplane is climbing is a sign that the seal between the pneumatic pressure regulator and the adapter has broken. The adapter should have a 101- 970120-9 gasket between the regulator body and the adapter, and it is installed with RTV-732. On older airplanes, the issue is with the adapter becoming brittle and cracking, having the same effect.
