lower breakaway panel, two decompression blowout panels, a lock assembly, and a deadbolt.
The door opens about a piano hinge mounted on the flight compartment partition. The hinge is attached to the partition with screws.
A light shield on the bottom edge of the door prevents incidental light from entering the flight compartment. This is to allow low level lighting on instrument panels.
An Observ-O-Scope in the door allows flight crew members to see into the passenger compartment.
The door has blowout panels installed that will open aft in the event of a decompression in the passenger cabin.
Electric Strike
The electric strike consists of a solenoid, a spring mounted strike, and a pin which prevents the strike from rotating.
The solenoid acts to lock the flight compartment door. When 28VDC is applied to the solenoid it closes, extending a pin to prevent the strike from rotating. This prevents the door from being opened from the aft (passenger) side.

FIXED INTERIOR DOORS -FLIGHT COMPARTMENT DOOR -CHIME MODULE
Chime Module
The chime module is mounted on the right hand door post inside the flight compartment.
The chime module controls the functions of the access system.
A removable cover on the chime module allows access to two switches that must be pressed to program the various time delays and items of the access system.
The programmable items are the Access Time Delay, the Deny Time Delay, Time of Continuous Chime, and Access Code, and the Chime/Doorbell function.
A guarded power cut off switch is installed on the chime module to allow normal maintenance and preflight access to the flight compartment when the airplane has electrical power.
When the switch is in the Up (guard extended) position, power is removed from the chime module and strike solenoid, which unlocks the door.
