Opening

[PAS, p. 2-30]

  • Electrically unlatched; receives power from Main batteries or forward emergency battery if no other source of power available.

  • Door and stairs free fall to open and extended position dampened by self-contained, recirculating hydraulic fluid.

Closing

[PAS, p. 2-30]

  • Utilizes hydraulic pressure provided by the left hydraulic system, PTU, or aux pump (powered by both main batteries).

  • Controlled by 2-channel computer. If fails to close, wait 20-30 seconds for channel to switch before making a second attempt.

  • When DOOR CLOSE switch selected CLOSE, left and right packs both switch off.

  • Once closed, the door electrically latches and is sealed by a rubber seal to maintain cabin pressure using eight small ports in seal allow cabin-pressurized air to enter. The seal gradually deflates when pressure differential decreases. After the door is closed, the left pack turns on followed by the right pack 10 seconds later.

Door switch on Security / Ground Service Panel

[PAS, p. 2-31] "MAIN DOOR" switch:

  • OPEN. With main batteries ON or EXTERNAL BATTERY switch ON, utilizes main battery power. Door electrically unlatches and opens via gravity, damper limits rate of opening. Amber “Door Open” legend illuminates whenever MED is open (regardless of switch used). Without other source of power, utilizes Fwd E-Batt.

  • CLOSE. EXTERNAL BATTERY → ON then select CLOSE. Aux pump auto activates if Left Hyd System pressure < 1500 psi. Powered by main batteries, door closes and electrically latches, aux pump auto shuts off. Need to select EXTERNAL BATTERY → OFF if it was used.

Main Entry Door Switch

[PAS, p. 2-31]

  • Located in vestibule area to right of door

  • At least one main battery must be ON if aircraft is unpowered

  • OPEN → Select. Door electrically unlatches and free-falls open, “Unlocked” amber light illuminates above the switch whenever MED is open (regardless of switch used). Without other source of power → Utilizes Fwd E-Batt

  • CLOSE → Select. Aux pump auto activates if Left Hyd System pressure < 1500 psi. Powered by main batteries. Door closes and electrically latches. Aux pump auto shuts off.

Emergency Entry PUSH Switch

[PAS, p. 2-32] Located on exterior of door, designed for emergency personnel use. Also used for crew on a routine basis. Push the panel, the Fwd E-Batt unlatches the door if their is no other power source.

Bayonets

[PAS, p. 2-33] Verify 3 red dots are visible on each side of the door to confirm the door is fully latched and locked with the bayonets in place.

Vent Flap

[PAS, p. 2-33] A circular flap integrated with the exterior of the door, ensures ≤ 0.5 psid until the door is fully latched and locked. Prevents the door from unlocking if &ge;; 2.0 psid.

Manual Open Handles

[PAS, p. 2-33]

  • Located underneath 4th step

  • Hinged surface of 4th step kept in place by magnets

  • Open surface of 4th step by simply pulling on outer edge

  • Yellow and blue handles will now be exposed

  • Instructions are engraved on metal plate

  • Step 1. Pull yellow handle to full extension until it can be rotated 90° CCW

    Step 2. Pull blue handle until door is unlatched

    CAUTION DOOR OPENS QUICKLY

    NOTE: Manual opening of the MED is considered a maintenance-only function. his should only be accomplished if no electrical power available to open the door. Further maintenance is required to reset the door for normal operation.

Acoustic Door

[PAS, p. 2-34]

  • Must be retracted (open) during taxi, takeoff, landing.

  • Manually close after takeoff by releasing catch assembly: release door from open position, manually slide door to closed position and latch via handle. Can also be closed and latched on ground with MED open (electrical power required to keep latch closed).

  • Automatically retracts open by spring loaded reels when flaps selected to 10° or landing gear extended.

  • Emergency Opening: if door fails to open normally or latch is stuck, grasp forward edge of forward door and slide aft (see placard).

Baggage Compartment Door

[PAS, p. 2-37]

  • Can be opened from inside or outside aircraft

  • Operation of door is inward and upward, guided on tracks that follow fuselage contour

  • Spring loaded reels assist opening the door and hold door in place once open

  • See placard for operating instructions. External door handle is flush with door skin when locked if green pin in interior handle is extended. If not extended: push external handle in from outside.

  • Features a passive seal to maintain pressurization.

Internal Baggage Door

[PAS, p. 2-35]

  • Serves as auxiliary pressure bulkhead door when closed to provides rotor burst protection. (If engine rotor blade enters baggage compartment, main cabin remains pressurized.)

  • Must remain closed > 40,000'.

  • Vented door latch equalizes pressure between cabin and baggage area before opening door. Rotate door handle 90° to vent. A lock button integral to the latch handle ensures that the latch stays latched when the door is closed and keeps the latch handle vertical to provide a solid handhold as the door is opened and closed.

  • (Effective S/N 72034-72xxx and 73015-73xxx) When operating the internal baggage door in-flight, it is recommended that the internal baggage door handle be held in the unlatched vertical position until differential pressure between the cabin and baggage compartment is reduced before opening the internal baggage door.

  • Note: The internal baggage door seal is passively inflated by cabin air pressure and needs no external source to seal. Once cabin air pressure is released the seal deflates.

[PAS, p. 2-36] The control panel is located above the door and includes a light switch, boom mic and headphone jacks, and a smoke evacuation valve.

Tail Compartment Door

[PAS, p. 2-38]

  • Lightweight door latched by 5 thumb latches. Key lock also located at aft end of door.

  • Access ladder attached: Unfold for entry to tail compartment. May remove from door for use elsewhere. Don't refuel while ladder is lowered (Increased weight may prevent from retracting and could also break the ladder.)

  • Peep hole in baggage compartment to see into tail compartment.

  • Tow bar also stored in tail compartment.
