FAA Aviation Mechanic - General (AMG) study guide
FAA Aviation Mechanic - General (AMG) · Work through your exam, one topic at a time.
The Aviation Mechanic - General (AMG) knowledge test is the general-subject written examination at the front of the U.S. aviation maintenance certification path. The FAA Aviation Mechanic - General (AMG) study guide has 11 sections and about 3,331 words.
01Basic Electricity
Electricity items on the General test are overwhelmingly Ohm's law, series and parallel rules, batteries, and the practical habits of wiring and bonding. Get the two circuit rules cold and most questions answer themselves.
325 words, about 2 min02Aircraft Drawings
Drawing questions test whether you can read a print the way a mechanic must: find the right part, use the right dimension, and know when a drawing is not a measuring device. Title and revision blocks.
317 words, about 2 min03Weight and Balance
Weight and balance rewards careful arithmetic more than memorization. The vocabulary: the datum is an arbitrary reference plane; a station is a location measured from it; an arm is the distance from the datum to an item's center of gravity; a moment is weight × arm; and the CG is total moment ÷ total weight.
311 words, about 2 min04Fluid Lines and Fittings
Fluid-line questions are about materials, flares, and the handling rules that prevent leaks and failures. Tubing is sized by outside diameter and wall thickness; pipe is sized by nominal inside diameter.
300 words, about 2 min05Materials and Processes
Materials questions cluster around identifying alloys and tempers, choosing the right inspection method, and knowing which processes change strength. 2024 (copper) is strong and fatigue resistant but corrodes easily, so it is usually Alclad, a thin pure-aluminum coating.
267 words, about 1 min06Ground Handling and Servicing
Ground handling questions test safety habits, the things that keep people out of propellers and airplanes out of the grass. Mooring and securing.
311 words, about 2 min07Cleaning and Corrosion Control
Corrosion is an electrochemical process that needs a metal, oxygen, and moisture. Questions ask you to name the type, choose the cleaner, and know how much metal removal is too much.
303 words, about 2 min08Mathematics
Math on the General test is applied arithmetic, not calculus: fractions, ratio and proportion, percentage, area and volume, unit conversion, and the formulas already used in weight and balance and electricity. Working with numbers.
285 words, about 1 min09Maintenance Forms and Records
Record-keeping questions are pure regulation recall, and they turn on which form, which signature, and how long the record is kept. FAR 43.9, maintenance records.
310 words, about 2 min10Maintenance Publications
The publications domain tests whether you know which document controls a decision and whether it is approved data or merely acceptable data. Hierarchy of authority.
277 words, about 1 min11Mechanic Privileges and Limitations
Part 65, Subpart E governs certificated mechanics, and the questions test the boundary between what you may and may not do. A mechanic holding an airframe and/or powerplant rating may perform or supervise the maintenance, preventive maintenance, or alteration of an aircraft or component for which he or she is rated, and may approve it for return to service.
