STC/ drawings for Swing out doors

[pitts10ch]

Hi guys,


I wanted to track down some drawings or paperwork for the seaplane swing out door mod for my m-5-235. Any ideas? Thanks.

I don't know of an STC but they have been modified since the '80's with 337's. Aircraft piano hinge across the top, a fore and aft bolt lock, a pressure cylinder to hold it up and a speed placard. It does not slam up or down but floats freely unless you slip the plane.
