Spars

Our spars are made from Aircraft Grade Sitka Spruce seasoned and dried to less than 10% moisture. One of the problems with the original spars is that they were made from fresh wood in a damp climate and would have to much moisture content. Then when they went to a hot dry climate they wanted to shrink and crack. Our spars are about 1/64 to 1/32" thicker than the originals. They are also maximum in depth (top to bottom). The doubler plates at the strut attach point are also longer. They are increased from 14" to 39" and fish mouthed on the ends. Two (2) to four (4) ribs need to be modified in each wing to accommodate the increased doublers. All the other ribs will fit. The 1/16" plywood butt plates are scarfed in so there is no void. Birch plywood plates are glued on with resorcinol glue, all holes are drilled with a precision drill fixture insuring accurate holes. The spars are finished with three (3) coats of epoxy spar varnish. We have an STC on the improved design of the spars for all of the 7, 8 & 11 series airplanes manufactured by Aeronca, Champion and Bellanca. We also have a PMA to make the spars. We can also make spars for Piper J-3, Taylorcraft L-2 & BC-12 and the prewar Aeronca part no 5-20 & 5-21.

Formers

Our formers or bulkheads as they are sometimes called are an improvement over the originals. First of all they are redrawn by Lofting on a computer. They are close to copies of the originals but more precise. The notches for the stringers fit the stringers. The originals were made from 3 ply fir plywood like you get at Home Depot with patches and voids. Ours are made from 5 ply Birch plywood. They have copper fairleads for the trim cables. They are cut with a CNC water jet which make them precise with no edge chipping. They are finished with two (2) coats of epoxy spar varnish. They are approved by STC and manufactured under a PMA.

Inspection Kits

Our Inspection Kits are designed to greatly facilitate the spar inspection mandated by AD 2000-25-02. Compression failures on the top of the spars at the ends of the plywood plating is the achilles heel of the whole spar inspection. Our inspection kits are designed to be flush sealable and secure. They are located directly over the areas that need to be inspected. Drawings and instructions are provided for installation. This is a STC-PMA item.

Floorboards

Our floorboards are of a refined design. They incorporate ACA Service Letter 436. This Service Letter widens the floorboards behind the firewall to the gear fittings. This is done to lessen the chance of dropping pens & etc that can get under the floorboards. They are CNC water Jet cut from 1/4" Birch plywood. The sheets are prevarnished before cutting and then varnished again after cutting. These are STC & PMA parts.

Stringers

Our stringers are made from Sitka Spruce. They are copies of the original profiles. They are not cut to length. They are sold as stock not airplane parts. A drawing is provided to cut the lengths and how to cut the ends. In the case of the 7 series airplanes without a skylight we form the forward ends and make a prepared splice in the two (2) stringers that go over the top of the cabin to get them to a UPS'able length. Most of the stringers we sell are for the 7 & 8 series airplanes, We can make stringers for any airplane.

Baggage Door

Our baggage door installs on the right side of the fuselage behind the rear seat on Citabrias and Scouts. this not only makes easy access for baggage but also for battery access. It is all aluminum and installs without welding. Easy to install if recovering but can be installed in a flying airplane. Presently we have been installing them by field approval but an STC is pending.

Landing Gear Legs

Rainbow Flying Service has a gear leg straightening service. We can straighten and recondition bent landing gear legs for Citabria, Scout and Decathlons. This is done by a prescribed method spelled out by Bellanca Aircraft Company. We only do this by pairs so that we can be sure to provide you a matched set. The early gear legs from 1967 to about 1970 have a straight back edge. Beginning in about 1970 the back of the leg tapered to just above the axle and then got wider at the axle. From about 1970 to 1972 the gear legs were identified with "F" and "J" serial numbers. From about 1972 to 1980 the gear legs were identified with "C" series serial numbers. The serial number is usually stamped on the bottom end of the leg. Beware there are some bogus gear legs out there that were sold on EBay. These can be identified by the absence of a serial number and they don't fill the clamp at the fuselage. We try to keep reconditioned gear legs in stock to sell on an exchange basis. We can do American Champion steel gear legs as well. Shims maybe needed to adjust toe in and toe out. We can supply the shims also. The gear legs are normally shipped out with a coat of Primer, we will paint a set of gear legs for $100 extra.

Rainbow Flying Service, LLC

Working on farm equipment during his younger years, Ron has always been mechanically-minded. Crop dusters intrigued him, and he decided he wanted to learn all he could about planes and become a pilot. After high school he attended Airframe and Powerplant school at Big Bend Community College and obtained his A and P license. He bought a derelict plane which he rebuilt, some of it in his mother's living room (with his mom’s permission!) and found an instructor and learned to fly. Since 1970 Ron has worked as an aircraft mechanic using his skill and experience to make sure your job is done right. Ron has his inspection authorization and commercial pilot’s license including airplane single engine land and sea and glider.

In his spare time Ron enjoys gardening, hunting sapphires in Montana with his wife and attending fly-ins. Rainbow Flying Service is a supporter of the Civil Air Patrol and the local CAP Cadet Encampment.
