Definition
The mechanical fasteners and small structural fittings used in aircraft assembly and maintenance, including bolts, nuts, screws, washers, rivets, pins, clamps, and similar items. In aviation, hardware refers to certified, traceable components manufactured to specific aerospace standards (such as AN, MS, or NAS specifications) rather than commercial-grade equivalents.
Plain English
The small metal parts — bolts, nuts, screws, rivets, and similar bits — used to hold an aircraft together. In aviation, these parts must meet strict standards, not just be picked up from a regular hardware store.
Context Anchor
Seen in aircraft maintenance, preflight inspection notes, parts catalogs, and logbook write-ups about loose, missing, worn, or replaced parts.
Derivation
From the older general meaning of 'hardware' as durable metal goods sold in shops. In aviation it carries a stricter sense: only parts manufactured and certified to aerospace standards qualify.
Why Pilots Care
Correct hardware maintains structural strength and prevents failures that could affect flight safety.
Intuition Check
Hardware does not mean computer equipment here, and it does not mean the mechanic’s tools. In this context, it means the small parts installed on the aircraft to hold things together.
Example Sentence 1
The mechanic replaced the worn hardware on the inspection panel with new AN-specification bolts and washers.
Example Sentence 2
Only approved aviation hardware may be installed on the control surfaces.
