Definition
Tools that are operated by hand rather than by an external power source such as electricity, compressed air, or hydraulics. In aviation maintenance, hand tools include wrenches, screwdrivers, pliers, hammers, files, and similar implements used by technicians to assemble, adjust, inspect, and repair aircraft components.
Plain English
Tools you hold and use with your own muscle power, like wrenches and screwdrivers, as opposed to powered tools that run on electricity or air.
Context Anchor
Seen in aircraft maintenance manuals, tool lists, hangar work, and discussions about proper tools for aircraft servicing.
Why Pilots Care
Pilots performing preventive maintenance authorized under FAR Part 43 (such as servicing, lubricating, or replacing certain items) typically use hand tools. Knowing the right tool for a task helps prevent damage to aircraft hardware and ensures the work meets airworthiness standards.
Intuition Check
Hand tools does not mean every tool small enough to hold. In maintenance, it means tools powered by your hands rather than by a motor, battery, or air pressure.
Example Sentence 1
The mechanic kept a complete set of hand tools in a rolling box so she could work on aircraft anywhere on the ramp.
Example Sentence 2
All hand tools must be inventoried before the aircraft is released to prevent foreign object debris.
