Schweizer 269/300 (U.S. Military: TH-55): Aircraft Covers from Bruce's Custom Covers

Back to Top

The Schweizer 269/300 Bubble Cover encloses the entire bubble canopy. The cover attaches at 2 points. Straps at the corners attach to the rear struts, with attachment buckles made of non-metal Delrin, designed for rugged outdoor use. Both the top and bottom hems of the cover have a special rope-hem feature in which they can be tightened to insure against wind-blown chaffing. For ease of installation, bubble covers are color-coded (red=left, green=right) with color swatches sewn into the corners.

Bubble Covers are made of nylon Silver Laminate. Bruce's Custom Covers developed Silver Laminate especially for aircraft protection. The outer material is a medium weight nylon treated for ultraviolet resistance and anti-static buildup. The inner lining is brushed nylon tricot knit. Silver Laminate is extremely reflective. Tests show that the cabin interior temperature can be reduced by as much as 25 degrees. It is water, ice and snow repellent, yet it is breathable enough to allow moisture to escape from between the cover and the windshield surface. Silver Laminate contains no hydrocarbon compounds which can harm plexiglass windshields and acrylic finishes.

The Engine Cover encloses the engine area from the rotor hub fairing aft to the tail boom. This cover encloses the sides and rear of the engine area. The cover fastens closed with a Velcro closure underneath the tail boom, and attaches to the helicopter with straps and buckles to the front struts. Like the bubble cover, the engine cover is color-coded with a rope-hem feature insuring the tightest fit. The engine cover is made of heavy weight nylon, available in a variety of colors.

The Rotor Hub Cover overlaps with the blade covers to insure complete protection for the entire main rotor system. This cover also encloses the rotor mast fairing, providing protection for the pitot tube at the fairing base. It is made of heavy weight nylon and fastens securely with Velcro and Delrin buckles.

Blade Covers are sewn of medium weight nylon pack cloth. Cut "full" to avoid trim tab damage, blade covers can be installed from the ground with the aid of lightweight rope which is attached to the open end. Covers are cinched tight at the blade root with straps and Delrin buckles. A small opening at the tip of the cover allows for some air circulation and drainage. For operations in extremely cold weather, blade covers can be fitted with full length zippers and "boots" designed to accept a pre-heater hose.

Blade Tie-Downs are "socks" which fit over the blade tip with or without blade covers installed. Each tie-down is fitted with a generous length of rope. Made of heavy weight nylon, tie-downs are available as a complete set, or individually.

The Tail Rotor Cover is a one-piece design which fits over the blades, hub and gearbox. It fastens with snaps along the bottom edge. Made of medium weight nylon, tabs have been sewn into the tips of the cover so that it may be tied down in high winds.

The Tail Boom Cover overlaps with the tail rotor/gearbox and engine covers to form a weatherproof seal. Fastening with Delrin buckles along the bottom of the tail boom, the cover is made of heavy weight nylon. Bungee cord sewn into the front and rear hems help keep the cover tight.

Vertical/Horizontal Stabilizers are "socks" which slip onto the stabilizers, tightening with bungee cords and Delrin snaphooks.
