Aviation Maintenance Technician Handbook–General Study Flashcards

Vocabulary and key concepts based on the FAA Aviation Maintenance Technician Handbook–General (FAA-H-8083-30B), covering safety, regulations, human factors, and fluid mechanics.

FAA-H-8083-30B

The official designation for the Aviation Maintenance Technician Handbook–General, used for preparing for mechanic certification with airframe or powerplant ratings.

Risk Diamond

A four-color segmented label used to identify manual risks: red for flammability, yellow for reactivity, blue for health, and white for special hazards, using a scale of $0$ to $4$.

Safety Data Sheets (SDS)

Formerly known as MSDS, these forms provide detailed chemical breakdowns, formulas, and emergency actions for hazardous materials according to OSHA requirements.

Foreign Object Damage (FOD)

Any damage to aircraft, personnel, or equipment caused by loose objects like broken runway concrete, shop towels, or safety wire.

Fire Triangle

The three elements required for a fire to occur: fuel, heat, and oxygen.

Class A Fire

Fires involving ordinary combustible materials such as wood, cloth, paper, and upholstery.

Class B Fire

Fires involving flammable petroleum products or other flammable/combustible liquids, greases, solvents, and paints.

Class C Fire

Fires involving energized electrical wiring and equipment.

Class D Fire

Fires involving flammable metals, often magnesium found in aircraft wheels, brakes, or improper welding operations.

Halon 1211

Bromochlorodifluoromethane ($CBrClF_2$), a colorless liquefied gas agent used on fires that leaves no residue and interferes chemically with the combustion process.

Halon 1301

Bromotrifluoromethane ($CF_3Br$), a liquefied gas fire extinguishing agent with the highest UL toxicity rating of $6$, characterized by a vapor spray.

Bowline Knot

A common anti-slip knot used for aircraft tie-down that is easy to tie and untie.

Dead-man

An item such as a pipe or log buried in a snow or ice trench used as a tie-down anchor for ski planes.

Fireguard

A person familiar with aircraft starting procedures stationed with a suitable fire extinguisher (at least $5$-pound $CO_2$) during engine start-up.

Hydraulic Lock

A condition in radial engines where oil or fuel accumulates in the lower cylinders, potentially causing damage to connecting rods if the propeller is forced to turn.

Hand Propping

The process of starting an aircraft engine by manually turning the propeller.

ATA iSpec 2200

The standard numbering system for aviation maintenance documentation provided by the Air Transport Association.

14 CFR Part 65

The Federal Aviation Regulation regarding the certification of airmen other than flight crewmembers, including mechanics.

14 CFR Part 43

The regulation governing maintenance, preventive maintenance, rebuilding, and alteration of aircraft.

PEAR Model

A human factors model used in maintenance representing People, Environment, Actions, and Resources.

The Dirty Dozen

A list of $12$ common human error conditions in aviation maintenance, such as lack of communication, complacency, and fatigue.

Specific Gravity

A physics concept defined in the handbook as the ratio of the density of a substance to the density of a reference substance.

Boyle’s Law

A gas law stating that the volume of a gas is inversely proportional to its pressure if the temperature remains constant.

Bernoulli’s Principle

A principle of fluid mechanics stating that as the velocity of a moving fluid increases, the pressure within the fluid decreases.
