Definition
Small metal fasteners used to permanently join sheets of metal in aircraft construction. A rivet is inserted through aligned holes in two or more pieces of material and then deformed (the tail end is hammered or pressed flat) so it cannot be pulled back out, locking the pieces together.
Plain English
Tiny metal pins that hold the metal skin and structure of an airplane together. Once installed, they stay in place permanently — they are not screws and they don't unscrew.
Context Anchor
Seen during preflight inspection of the wings, tail surfaces, and other exterior metal panels.
Derivation
From the Old French 'river,' meaning to fix or fasten. The word has been used for centuries to describe fasteners that, once set, are not meant to come apart.
Why Pilots Care
Rivets maintain the structural integrity of the airframe. Missing, loose, or damaged rivets can signal fatigue, corrosion, or impact damage requiring further inspection.
Analogy
Like the little round metal dots that hold the panels of an aluminum canoe or toolbox together, except aircraft rivets are engineered for flight loads and vibration.
Intuition Check
Do not think of rivets as screws or bolts. A rivet is usually a permanent fastener; it is not removed by turning it with a screwdriver or wrench.
Example Sentence 1
During the preflight, the pilot ran a hand along the wing's lower surface, checking that no rivets were missing or popped.
Example Sentence 2
After the annual inspection the mechanic replaced several rivets along the horizontal stabilizer to restore a tight fit between the skin and spar.
