Wanting to install a large bag door on a Bonanza E33, S/N CD1174. Do you know if there is an STC for this that can be purchased? Drawings available? Previous field approval information? Location? Thanks. Jim Brendel 916-759-0450
You do not need a 337 form since it is not a major alteration. The frame is exactly the same at the front and all along the top and bottom. After you drill out the old one you can cleco in the replacement and cut the skin.
