What are these hinges supposed to hold???
pressurized canopy?
undercarriage trunion?
control surface?

Well, the Sisu 1A sailplane used aircraft grade piano hinges in instead of
spar root fittings. The right and left wings were joined to each other with
1/16" piano wire inserted through hinges riveted to the upper and lower wing
skins. The fuselage was hung from the joined wings.
