Wipaire offers full support, in terms of both maintenance and repairs, for the full line of Wipline floats.
Float Component Repairs
It’s a foggy morning, the plane is full of cool morning dew. It paints a pretty picture. But your hydraulic system is screaming for help.
It is not uncommon to perform winter maintenance on a customers floats and pass by the required maintenance on the hydraulic pump reservoir. It can not be done. The aircraft is on skis somewhere catching crappies. The pump is no where to be found. The powerpacks can be mounted in several areas of the aircraft. Some are worse than others. Mounting on the firewall presents heating and cooling problems resulting in condensation. Condensation in the floats is pretty harsh with 100% humidity and with those pretty dewy mornings the aft fuselage is a problem area as well.
Wipline floats require 100 hour/yearly cleaning of the pump reservoir and screen. This is a collection area for water, dirt and debris. We find reservoirs are neglected catch points for all sorts of bad stuff. High amounts of moisture over a years time can cause a black slime which slows gear retraction times and starves the pump of fluid. It is also a good indication of any problems starting. Just like an engine, your hydraulic system can make metal. If a cylinder is galling or a pump is failing, metal chips can be found. If you remove your floats and perform winter maintenance, be sure to clean your reservoir and add fresh fluid.
Wipaire services offers Wipline float component repair. Whether scheduled to coincide with your float inspection or an AOG situation, Wipaire experts can provide repairs to your float components for minimal down time to keep you in the air.
Wipline 6100 and 8000 Axle Replacement
Years of service can leave your axles in rough shape with corrosion, damage to seal areas or bad threads. Wipaire services can remove your axles from your drag link assemblies and install new axles, saving you thousands of dollars over replacements. All assemblies are returned with Yellow tags, log entries, and FAA Form 8130-3 documents.
All Wipline Float Shock Struts
Shock struts on Wipline Floats are required to be removed, disassembled, cleaned, and serviced with proper fluid per Wipline Service manuals. (See float model specific schedules below) All seals, scrapers, and O rings are replaced and new fresh MIL-H-5606 Fluid added. Wipaire can perform your shock strut servicing to coincide with your float inspection for minimal down time. All assemblies are returned with Yellow tags, log entries, and FAA form 8130-3 documents.
Wipline 2100, 2350, 3000, 3450 Shock Struts
Hard landings, age and over gross wt. operations can damage your shock strut bushings. Let Wipaire service safely and quickly replace your bushings to minimize down time and keep you in the air.
We will also check for compliance with all the latest service letters issued against these components.
Wipline Float Hydraulic Powerpacks
All Wipline Float powerpacks require cleaning of hydraulic reservoirs every 100 hours per Wipaire service manuals. They are a catch point for moisture, mold, dirt and debris. If you require additional repairs to your hydraulic powerpack assembly, Wipaire float experts can perform repairs quickly to keep you in the air. We can perform this during the off season or to coincide with your float inspection for minimal down time. All powerpack assemblies are thoroughly inspected, repaired as required and returned with Yellow tags, log entries, and FAA form 8130-3 documents.
