Definition
The structure of struts and wires on a biplane that supports the upper wing above the fuselage. The cabane connects the top wing to the fuselage and holds it at the correct distance, angle, and alignment relative to the lower wing.
Plain English
On a biplane, the cabane is the framework of metal posts and bracing wires that holds the top wing up off the fuselage, like a small scaffold sitting on the body of the aircraft.
Context Anchor
Seen in discussions of biplane structure, preflight inspection, restoration, and maintenance.
Derivation
From the French cabane, meaning 'hut' or 'cabin.' Early aircraft designers used the word because the arrangement of struts above the fuselage resembled the simple framework of a small hut. Knowing this helps the term stick — the cabane is the little 'hut' of struts holding the top wing.
Why Pilots Care
On a biplane, the cabane carries significant flight loads from the upper wing into the fuselage. Cabane struts and their fittings are routine inspection points during preflight and annual inspections, since corrosion, cracks, or loose fittings here can compromise wing alignment and structural integrity.
Intuition Check
Do not confuse cabane with cabin. A cabane is a support frame for the wing; a cabin is the enclosed space for people or cargo.
Example Sentence 1
During preflight on the Pitts, he inspected each cabane strut and fitting for cracks before climbing into the cockpit.
Example Sentence 2
Early biplanes relied on the cabane to keep the upper wing properly aligned.
