  • Page 15: General Float Information

    SERVICE MANUAL & ICA 8750 AMPHIBIAN/SEAPLANE FLOATS ON CESSNA 208/208B 1.1 GENERAL FLOAT INFORMATION The model 8750 amphibious float is an all aluminum structure. The alloy used throughout is mostly corrosion resistant 6061-T6, with 2024-T3 and 7075-T651 used in strength critical fittings and panels. Interior parts are cleaned, acid-etched and then primed prior to being riveted for enhanced corrosion resistance.

  • Page 16: Figure 1-7: Hydraulic Fluid Level Placard

    SERVICE MANUAL & ICA 8750 AMPHIBIAN/SEAPLANE FLOATS ON CESSNA 208/208B accordance with the installed placard using MIL-H-5606 (red) hydraulic fluid. The fluid level placard (Figure 1-7) is installed on the forward hydraulic Reservoir. FIGURE 1-7: HYDRAULIC FLUID LEVEL PLACARD The nose wheels are fully castoring for maneuverability while the airplane is under engine power or being towed. The main landing gear has dual 6:00x6 8-ply tires and the nose gear has a single 5:00x5 10-ply tire.
  • Page 17 SERVICE MANUAL & ICA 8750 AMPHIBIAN/SEAPLANE FLOATS ON CESSNA 208/208B STRUT PACKAGE The strut package attaches the floats to the aircraft. The strut package is comprised of the forward struts, main pylons, rear cross-wires, and front cross wires (or flying wires). The streamlined struts are made from extruded aluminum alloys.

  • Page 18: Cleaning

    SERVICE MANUAL & ICA 8750 AMPHIBIAN/SEAPLANE FLOATS ON CESSNA 208/208B 1.2 CLEANING The outside of the float should be kept clean by washing with fresh water and soap. Special care should be taken to remove engine exhaust trails, water-line marks, and barnacle deposits. After salt water operations, washing with fresh water should be done daily with special attention paid to hard to reach places like: - skin seams - wheel well areas...

  • Page 19: Corrosion

    Cladding, plating, anodizing, painting, greasing and waxing are all processes used to help protect metal from corrosion; Wipaire uses all these techniques during manufacture. But due to the rugged way our floats are used and the environment, these surface sealers become abraded or wear away, leaving the metal exposed.

  • Page 20: Float Handling & Jacking

    When towing the amphibian aircraft, two lugs are provided on the lower forward side of the nose spring. A rigid “V” frame can be fabricated to attach to these lugs for towing the aircraft with a tractor. Wipaire parts has this tow bar available for purchase.

    SERVICE MANUAL & ICA 8750 AMPHIBIAN/SEAPLANE FLOATS ON CESSNA 208/208B 1.5 MOORING For land operations, the aircraft is equipped with three fixed mooring points. Two are located on the outboard edge of the wing struts and the other is located on the underside of the tail section of the aircraft. Mooring Procedure on Land: 1.

    Reference the Wipaire Structural Repair Manual (SRM) for allowable corrosion/material loss limits. Corrosion is usually detected visually, which is why Wipaire strongly recommends the previous cleaning and inspection procedures. It can appear as a white or pale green powder, discoloration of the metal surface, or bubbles and blisters under the surface of the paint.
  • Page 69 SERVICE MANUAL & ICA 8750 AMPHIBIAN/SEAPLANE FLOATS ON CESSNA 208/208B After removing the corrosion, restore the area to the original finish, like prime and enamel, or coat the metal with a waterproof grease. CORROSION X, or equivalent, should also be applied to stop corrosion and repel moisture and contaminants.
