Page 10: Section 3: Deploying The Bucket
Section 3: Deploying the Bucket Section 3: Deploying the Bucket Attaching to the Cargo Hook The Bambi Bucket is rigged for a lateral cargo hook. Correct attachment is indicated when the name plate on the control head faces forward in flight. This ensures that the ballast on the Bambi will face forward in flight. -
Page 11: Connecting Power
Section 3: Deploying the Bucket Control Head Orientation - Models 5566-HL9800 For these models, it may be necessary to use a second shackle to rotate the bucket 90°. WARNING Ensure that all shackles are rated with a minimum safety factor of five for the gross weight of the bucket as shown on the data plate. -
Page 12: Checking Tail Rotor Clearance
Section 3: Deploying the Bucket Checking Tail Rotor Clearance WARNING Using a Bambi Bucket with insufficient tail rotor clearance could result in a tail rotor strike which could result in serious injury or death. NOTICE If using a longline, the minimum recommended length is 50 ft (15 m). When a Bambi Bucket is attached directly to the helicopter cargo hook or attached using a longline less than 50 ft (15 m) in length, it is important to confirm that there is adequate tail rotor clearance. -
Page 13: Instant Deployment System (Ids)
Section 3: Deploying the Bucket If the tail rotor clearance is insufficient, shorter suspension lines, triplines/riser, ring and restrainer, and deployment lines must be used and can be ordered from SEI. Please specify the model and serial number when ordering parts. Instant Deployment System (IDS) The instant deployment system uses a hub and spoke mechanism to automatically expand the mouth of the bucket... -
Page 14: Section 4: Flight Operations
Section 4: Flight Operations Section 4: Flight Operations Flying the Bucket The Bambi Bucket should be flown in accordance with the United States Forest Service recommendations limiting all helicopters, other than tandem rotor, to a maximum 80 KIAS while conducting external cargo hook operations. -
Page 15: Filling The Bucket
Section 4: Flight Operations Filling the Bucket Once the Bambi Bucket touches the water surface, it immediately tips and sinks. This is a result of the ballast on one side of the bucket which makes it unstable on the water. A Bambi Bucket does not have to be towed to make it sink. - Page 16 Section 4: Flight Operations Variable Fill Capability The pilot can vary the bucket’s capacity by the speed at which it is pulled from the water. As the submerged bucket is lifted, water pressure expands the fabric bucket shell and its internal fiberglass battens flex outward, increasing the bucket’s volume.
-
Page 17: Dumping The Bucket
Section 4: Flight Operations Dumping the Bucket To dump water from the bucket, simply push and release the dump switch. The weight of the water inside the bucket will cause the fabric dump valve to turn inside-out through the bottom of the bucket, giving obstruction-free passage to the escaping water and producing the best possible dump pattern. -
Page 18: Landing
Section 4: Flight Operations Landing The recommended landing procedure allows the bucket to touch down ahead of the helicopter and then maintain tension on the suspension lines by backing up slightly, thereby keeping the control head at an angle while landing. CAUTION To avoid damage to helicopters with low skids, never land on a vertical control head. - Page 19 Section 4: Flight Operations THIS PAGE INTENTIONALLY LEFT BLANK Bambi Bucket Operations Manual...

Page 20: Section 5: Using Accessories
Section 5: Using Accessories Section 5: Using Accessories Firesock When using water, the Firesock breaks down water droplets, thereby increasing the exposed surface area. This allows for improved coverage and increased drop accuracy as well as wider and longer drop patterns When using foam, the Firesock increases the aeration of the foam. -
Page 21: Powerfill Snorkel
Section 5: Using Accessories PowerFill Snorkel PowerFill Snorkel is a system which allows partial or complete bucket fills from a range of previously inaccessible water sources as shallow as 18” (0.46 m) including streams, ponds and low profile dip tanks. It is available for bucket models 1821 –... - Page 22 Section 5: Using Accessories Once a fill has been started, the bucket will need to be supported by maintaining some tension on the suspension lines, particularly when the bucket is nearly full. If the bucket is not supported, the flexible nature of the bucket shell may allow it to collapse to one side as the water load increases.
-
Page 23: Foam Injection Systems
Section 5: Using Accessories Foam Injection Systems Sacksafoam is a foam injection system that uses a pump to dispense a controlled amount of foam concentrate from a reservoir into the water in the bucket. The operation of the Sacksafoam is controlled by the pilot through a control unit, which is mounted in the cockpit. -

Page 26: Section 6: Packing And Storage
Section 6: Packing and Storage Section 6: Packing and Storage Packing the Bucket 1. Collapse the IDS by pushing the hub into the bucket. 2. Grab the control head and pull the suspension lines taut. Tape the lines together in two bunches. 3. - Page 27 Section 6: Packing and Storage 5. Gather the suspension lines into a coil and stow inside the bucket. Place the control head outside of the bucket to prevent the possibility of the lines tangling. 6. Avoid any sharp folds along the base of the shell as this protects the shell from delamination which can occur if the Bambi Bucket is stored for a long period of time.

Page 28: Storing The Bucket
Section 6: Packing and Storage 9. Take the carrying bag and drape it over the bucket. 10. Roll the bucket over and insert the bucket into the bag. Storing the Bucket Prior to storage, wash the bucket with fresh water and dry completely to prevent the growth of mildew and the corrosion of aluminium and steel parts. - Page 29 Section 6: Packing and Storage THIS PAGE INTENTIONALLY LEFT BLANK Bambi Bucket Operations Manual...
