SH/HH-60F/H EAWS SPECIFIC

1. State the function and location of the following fuselage components.

a. Cockpit section:
Front section, seats pilot and copilot. Contains all flight control.

b. Cabin section:
Aft of the Cockpit, seats aircrew and hold cargo and ASW equipment.

c. Transition section:
Aft of the cabin, holds avionics, tail strut, main fuel tank.

d. Tail cone:
Aft of the transition section, houses drive shafts.

e. Tail rotor pylon:
Aft of the tail cone, a foldable section at the aft end of helo that supports the horizontal stabilator, IGB, TGB and tail drive shaft flight controls.

f. Main rotor pylon:
Attached to the upper cabin transition section covering and protecting the subsystems below it. Houses the hydraulics system, transmission system and main rotor.

To protect helicopter incase the airframe come in contact with wires in its path of flight. The system consists of seven cutter blades, (2 on hydraulics bay door [dog house], 2 nose avionics bay door, 1 in front of each landing gear) to cut the wire, and deflectors to deflect the wires.

a. Main rotor blades:
4 main rotor blades, receives power from the main rotor head. Provides thrust and lift. The blades are attached to the main rotor head.

b. Main rotor head:
Transmits the movement of the flight controls to the 4 main rotor blades. Located on top main transmission.

c. Tail rotor:
4 paddles are 2 interchangeable graphite blades provide 2.5% of lift in a hover. Located on the Tail rotor pylon.

d. Horizontal stabilator:
Keeps forward flight stable. Located on the tail rotor pylon.

e. Collective stick:
Change pitch of the main rotor blades increases and decreases lift. Located in the cockpit.

f. Cyclic stick:
Provides forward, aft, and lateral movement. Located in the cockpit.

g. Rudder pedal:
Control helicopters heading. Change pitch of tail rotor blades to turn aircraft. Located in the cockpit.

a. Reservoirs: Stores hydraulic fluid, 5 on SH-60F (4 on HH-60H).

1) Attached to the #1 hydraulic pump
2) Attached to the #2 hydraulic pump
3) Attached to the back-up hydraulic pump
4) Servicing reservoir in hydraulic bay
5) (SH-60F only) Attached to the utility hydraulic pump

b. Pumps: Pump hydraulic fluid, 4 hydraulic pumps (3 on the HH-60H).
1) #1 hydraulic pump located in the hydraulic bay
2) #2 hydraulic pump located in the hydraulic bay
3) Back-up hydraulic pump located in the hydraulic bay
4) (SH-60F only) Utility hydraulic pump located at the four o’clock position of the main transmission module

c. Servos:
Uses hydraulics to boost pilot’s input in the flight controls. Located in the hydraulics bay.

a. Main landing gear:
To support the weight of the aircraft and absorb the landing forces as well as provides ground braking ability.
b. Tail landing gear:
To support the weight of the aircraft and absorb the landing forces as well as provide ground steering control.
c. Recovery, Assist, Secure, Traverse (RAST) system:
To assist in handling the helicopter during high sea states. It’s capable of :
1.) Assisting the pilot in landing the helicopter in the flight deck. (RAST capable ship only.)
2.) Securing the helicopter to the deck.
3.) Straightening the helicopter to a laterally centered position.
4.) Traversing the helicopter into and out of the hangar.

a. Rescue hoist: Lowers and raises swimmer, survivor, and cargo. Located above the main cabin door.

b. Cargo hook: Used for external transfer of cargo. Holds up to 6000 lbs. Located in main cabin floor.

c. Fire detector: 2 in each engine comp/and 1in APU comp, detects infrared energy (flame).

d. Fire extinguishers: 2 bottles with 2 shot capability to engine compartments and or APU.

Air conditioning for cooling electrical equipment and crew.

201.5.1 What caution or warning must be observed when working with the following?

a. Rescue hoist:
Has a CAD installed, do not maintain equipment with CAD installed.

b. RAST:
Has a CAD installed and a spring-loaded main probe, stand clear.

c. Flight controls:
Activation of the back-up pump while personnel are on top of the helicopter will the flight controls to move control surfaces. This could cause injury or death.

a. Main rotor head:
Due to orientation main rotor, enter and exit the aircraft at the 3 or 9 o’clock position only.
b. Tail rotor:
Could dip low enough to cause injury or death.
