LOWE STC - Whats Involved?
This conversion can use any of the three available C120/140/140A gear legs: The early gear with the 1/4" axel bolts, the early gear with the 5/16" axel bolts, or the forward swept gear that was found on late 1947 and on airplanes. HOWEVER, if using the forward swept gear, you MUST install the four extruded bulkhead support angles (that are extremely hard to find).
The Lowe Tailwheel Conversion requires that you remove the floor pans of the airplane and install cessna 120/140 gear boxes in the forward bulkhead area. Then install the forward gear.
After the forward gear is on, you can remove the rear gear box as well as one of the bulkeads that held the previous main gear in place.
You replace the belly skins where the previous gear was and the new belly strap where the new gear will go, and patch the nosewheel steering control holes. You will be adding support stringers along the belly skins just like the 120s and 140s had.
Remove the engine and engine mount and either replace the engine mount with a Cessna 140A engine mount or have the 150 mount altered to remove the nose gear supports and turn it into a 140A engine mount duplicate.
Remove the tailcone at the second to last bulkhead, and modify the bulkhead to allow the tailwheel support angle brackets to pass by the bulkhead. Install the tailwheel bracket and the long tailwheel angles that attach to the tailwheel bracket. Modify the Rudder control horn for rudder steering, or install eyebolts for steering.
Obviously this is a simplified version, and if you are doing the conversion use the istructions provided. This is just a short, brief summary to let you know what you are getting yourself into if you decide to do this on your own. It is NOT to be used for the conversion, but to give you an idea of whats involved.
How long will it take? That depends on how much you work on it!
Ask David for more information about that.
