Hoisting Flashcards
HOIST CABLE FOULED/DAMAGED
Symptoms:
● The hoist cable, hook, or rescue device becomes fouled or secured on the deck or ground
● Hoist cable is visibly damaged (e.g., kinked, bird-caged, or broken strands)
WARNING
If the hoist cable is damaged (e.g., kinked, bird-caged, or broken strands), the cable shall not be used for hoisting, nor shall the damaged portion be retrieved into the hoist assembly. Use of the quick splice should be considered.
If injury or damage is imminent:
1. ACTIVATE HOIST SHEAR SWITCH WHILE ANNOUNCING - “SHEAR,
SHEAR, SHEAR” (PF/PM/FM)
2. ANNOUNCE - “CABLE IS AWAY”
If conditions permit:
3. PAY OUT SLACK IN CABLE
4. ANNOUNCE – “CABLE FOULED”
5. DIRECT THE VESSEL CREW TO FREE THE CABLE
If unable to free the cable or the cable is damaged:
6. CABLE - CUT WITH CABLE CUTTERS
7. ANNOUNCE - “CABLE IS AWAY”
CAUTION
● With the quick splice installed there is no spring buffering and it is unlikely the up-limit switch will
actuate.
● Severe damage to the hoist or cable may result if the quick splice is run to the up-limit switch.
If mission dictates:
8. QUICK SPLICE - ASSEMBLE
NOTE
Consideration of remaining cable
HOIST FAILURE
Symptom:
● Hoist fails to respond to flight mechanic inputs
NOTE
Any secondary hydraulic isolate condition (e.g., secondary hydraulic low fluid/loss of fluid, No. 2 DC Bus Short, etc.) will cause the normal electrical power to be removed from the hoist.
Corrective action:
1. ANNOUNCE - “HOIST FAILURE”
2. ADVISE THE PF - "COMMITTED" OR "NOT COMMITTED"
If committed:
3. CABLE AND DRUM - CHECK FOR FOULING
4. EMERGENCY HOIST POWER - ACTIVATE
If hoist power is not restored:
WARNING
During manual override (step 1 valve) operations, the up-limit switch will be inoperative. Do not run the hoist hook to the up-limit switch.
5. MANUAL OVERRIDE - ACTIVATE
CAUTION
The manual override (step 1 valve) shall be closed when the rescue device/RS is in the cabin to prevent
hoist creep.
If hoist fails to respond:
6. RESCUE DEVICE - RETRIEVE
If unable to retrieve rescue device:
7. CABLE - CUT OR SHEAR
NOTE
When a survivor or rescue swimmer is attached to the hoist, on scene conditions will dictate possible courses of action. Refer to Rescue Swimmer Emergencies in this section.
8. ANNOUNCE - “CABLE IS AWAY”
If not committed:
9. ABORT THE HOISTHOIST BOOM FAILURE
Symptom:
● Hoist boom does not respond to electrical control inputs
NOTE
The BOOM STOW and BOOM IN-OUT switches work independently of each other. The BOOM STOW switch will operate regardless of MASTER or EMERGENCY switch positions, as long as the No.1 MAIN DC BUS is powered.
Corrective action:
1. ANNOUNCE - “BOOM FAILURE”
2. HOIST MASTER SWITCH - CHECK CREW POSITION
3. HOIST ACT CONTROL AND HOIST ACT POWER CIRCUIT BREAKERS
(2) - CYCLE (Hoist Boom R1 No. 1 and R2 No. 1)
If boom is not in the fully stowed position and does not respond to electrical control inputs:
4. HOIST ACT circuit breakers (hoist boom R1 and R2 No. 1) - PULL
5. Hoist operator pendant - Disconnect
6. Manual crank - Install
7. Manually crank boom to stowed position
8. Manual crank – Remove
If unable to move boom:
9. Observe Hatch/Door speed limits, if applicable
HOIST ELECTRICAL RUNAWAY
Symptom:
● Hoist cable extends/retracts without crew input
Corrective action:
WARNING
● Do not secure the cockpit hoist master switch as all shear capabilities will be lost.
● Once power is secured, on certain hoist control panels, the hoist boom will not respond to FM inputs.
Turning power back on could induce another hoist electrical runaway. Pulling in the rescue device and/or survivor without the assistance of the boom may be necessary.
1. HOIST POWER - SECURE AT THE HOIST CONTROL PANEL
NOTE
Due to integration of the new hoist control panel, booming in and out will be inoperative when the power is secured at the hoist control panel. Do not turn hoist power back on to operate the hoist boom due to possibly recreating the runaway emergency.
2. ANNOUNCE - “HOIST RUNAWAY”
3. ADVISE THE PF - “COMMITTED” OR “NOT COMMITTED”
If committed to the hoist or mission urgency dictates:
WARNING
During manual override (step 1 valve) operations, the up-limit switch will be inoperative. Do not run the hoist hook to the up-limit switch.
4. MANUAL OVERRIDE - ACTIVATE
If not committed to the hoist:
5. ABORT THE HOIST
LOST COMMUNICATIONS DURING HOISTING OPERATIONS
Symptom:
● PF and/or FM unable to hear and/or talk during a hoist
Corrective action:
1. FM - TAP THE PF AND GIVE HOLD SIGNAL (closed fist)
2. ADVISE THE PF - “COMMITTED” OR “NOT COMMITTED”
If committed:
3. COMMUNICATE BY VOCAL COMMANDS AND CONTINUE HOIST
If not committed:
4. ABORT THE HOIST
If communications are still not restored:
5. Refer to ICU FAILURE or LPCAP FAILURE procedure
NOTE
If crew LPCAP is operable, FM
LOST RS
Corrective action - Day: 1. MARK AND RECORD POSITION 2. TRANSITION AND ESTABLISH RIGHT ORBIT 3. LOOK AND LISTEN FOR RS SIGNAL 4. WHEN VISUAL - RESUME HOVER POSITION If these procedures fail to relocate RS: 5. COMPLETE LEAVING RS ONSCENE PROCEDURE Daytime RS signals may include one or more of the following: a. Radio, prebriefed frequency b. Smoke c. Mirror Corrective action - Night: 1. MARK AND RECORD POSITION 2. FLASH LANDING/HOVER LIGHT 3. LOOK AND LISTEN FOR RS SIGNAL 4. WHEN VISUAL - CEASE FLASHING LIGHT If these procedures fail to relocate RS: 5. COMPLETE LEAVING RS ONSCENE PROCEDURE Nighttime RS signals may include one or more of the following: a. Radio, prebriefed frequency b. Strobe light c. Flare
EMERGENCY RECOVERY OF RS
Signal: IN TROUBLE, NEED ASSISTANCE is observed.
WARNING
If the aircrew observes a hazard to the RS in the water, hoisting of the RS should be initiated by placing the rescue device or bare hook between the RS and the hazard.
NOTE
● The RESCUE BRIEF is not required if the IN TROUBLE, NEED ASSISTANCE signal is observed.
● If two or more RSs are in the water and the rescue basket is sent down, the RSs may disconnect the rescue basket and connect to the hoist hook utilizing the lifting V-ring on the RS harness.
Corrective action:
1. RESCUE BASKET - IF RIGGED AND EMPTY
2. BARE HOIST HOOK - IF BASKET NOT READILY AVAILABLE
3. WITH THE ASSISTANCE OF THE FM, THE RS SHALL ENTER THE CABIN BACKWARDS
LEAVING RS ONSCENE
In the event the aircraft departs scene due to serious malfunction or other reason:
1. MARK AND RECORD POSITION
2. DEPLOY LIGHTED RAFT
3. DEPLOY DMB
4. Notify OPCEN or other rescue resource
NOTE
The survivability of the abandoned RS and survivor is enhanced by providing any extra equipment possible (e.g., LR-1 raft, hypothermia bags, EMT kit, etc.) on scene prior to aircraft departing.
