PK 2050A

PK 2050A Amphibious Float

The PK 2050A is the lightest amphibious float in its class. These floats weigh under 400 lbs, measured on FAA approved scales. Once installed on the aircraft there is a net gain of approximately 285lbs, after subtracting the weight of original landing gear.

FLOAT DESIGN
The basis for design for the PK 2050A was the PK 2250A. The hull has been redesigned for a lower gross weight. The spreader bar lug of the 2050A is CNC machined from aluminum and anodized for corrosion protection. This float features stainless steel swing arms on the main gear and composite leaf springs with shimmy dampeners on the nose. The 2050A has a double puck braking system that will greatly improve braking power and reduce braking distance. The hydraulic system is installed in the left hand float compartment and brand new design for this float. The installation of the power pack in the float reduces plumbing, therefore reducing weight. The rear bottom is made from a single sheet of aluminum to increase strength and maintain watertight integrity. Forward of the step there is a robust keel that is nearly ½”x½” in cross section. The 2050A features four hydroboosters forward of the step, which improve takeoff performance. The combination of keel, hydrobooster and internal “T” stiffeners forward of the step create a very strong bottom structure.

CORROSION PROTECTION
Prior to assembly, all aluminum components, including skins and bulkheads, are chemically treated and then epoxy primed. During assembly, the floats are fully sealed to create a watertight structure. All dissimilar metals are isolated to prevent corrosion. Following assembly, the exterior of the floats are cleaned and painted with two coats of aluminum pigmented lacquer or color matched to the plane with urethane paint.

MAINTENANCE & REPAIR
The PK 2050A float is manufactured using flat sheet aluminum, there are no specially formed bottoms, or stamped bulkheads. Therefore skins can easily be replaced in the event of severe damage. This also means that in the event of an emergency, field repairs can be made with ordinary hand tools.

PERFORMANCE
The basic hydrodynamic configuration of the float is a deep-V design. The high sternpost angle permits small radius turns and freedom during aircraft rotation at takeoff. Rough water operations are unsurpassed because of the deep-V design of the bottom. Takeoff distance on glassy water is reduced, because of the addition of four hydroboosters, even in high density altitude conditions.
