Pneumatic De-icer Replacement

If the de-icer is beyond repair, replacementment is offered at below the manufacturere's suggested uninstalled list price on most aircraft. A trained, licensed technician can install new de-icers at Wiley Post Airport (KPWA) or at the location of your choice.

There is no technician travel time charge for travel to your site. Travel expenses include airfare or mileage to your site, lodging, per diem, etc. A courtesy or rental car is required if travel is via airline.

BootsEdge is an official installation center for Ice Shield Pneumatic De-icers (formally SMR Technolgies). BootsEdge also installs Goodrich pneumatic de-icers.

Ice Shield offers up to $300 rebate on new de-icer purchases. This combined with no travel time charges, no sales tax, and no delivery charges can result in huge savings when replacing your de-icers. Ice Shield supports over 85% of the general aviation aircraft operating today. Ice Shield guarentees 48 hour delivery. If a de-icer can not be repaired, a replacement de-icer from Ice Shield, with a guaranteed delivery time, ensures less down time for your aircraft.

Ice Shield de-icers are FAA STC/PMA approved and are interchangeable with existing de-icers. Ice Shield's Edge Guard Sealing System results in proven life extension. Ice Shield 2 de-icers were designed for the most popular older aircraft, ftting the exact footprint of the older Type 23, tube type de-icer. Installation is simple because the footprint is the same leaving no exposed areas needing back-fill or paint.

De-icer damage can usually be associated with the static electric discharge system not functioning properly. If the static electricity accumulated in the de-icer cannot be expelled through the static discharge system, the static electricity can discharge through the de-icer, causing holes and air leaks in a short period of time. It is essential that the static discharge system operate correctly before de-icer repair or replacmentis performed. Limited Warranty does not cover damages caused by a faulty static discharge system.
