FAA Aviation Mechanic - General (AMG) study plan

Convert fluently between fractions, decimals, and percentages, and solve ratio, proportion, area, and volume problems using the formulas permitted on the FAA supplement.

State the definition and unit for voltage, current, resistance, and power, and write Ohm's law in all three algebraic forms.

Compute total resistance, current, voltage drop, and power for two- and three-resistor series, parallel, and series-parallel circuits without arithmetic errors.

Identify the standard schematic symbols for cell, battery, resistor, capacitor, inductor, switch, relay, circuit breaker, and ground.

Differentiate DC generators from alternators and explain the function of rectifiers, inverters, and voltage regulators in an aircraft electrical system.

Explain wire sizing and voltage-drop limits, and select the correct fuse or circuit breaker for a stated load.

Identify on a described drawing the title block data, fuselage station, buttock line, waterline, and zone number for a given part location.

Interpret orthographic views (top, front, side) and match a described three-view part to the correct shape description.

Convert drawing dimensions between inches-and-fractions and decimal inches to the nearest 0.001 inch.

Compute total weight, total moment, and center of gravity in inches and in percent of mean aerodynamic chord for a given loading, then state whether the result is within limits.

Solve weight-shift and weight-change problems (added or removed equipment, moved baggage) and recompute CG to confirm it stays in range.

Distinguish tare weight, net weight, and empty weight, and list the required precautions when jacking and weighing an aircraft.

Identify flareless (AN/MS) and flared tube fittings, AN sleeves and nuts, and explain the difference between 37-degree and 45-degree flares and where each is used.

Describe correct tube routing, bend radius, support spacing, and the selection of rigid versus flexible fluid lines for a stated pressure and vibration environment.

Classify aluminum alloys by four-digit series and temper designation and name a typical aircraft application and heat-treat response for each major series.

Distinguish ferrous from nonferrous metals and identify the corrosion-resistant steels and their inspection concerns.

Explain annealing, normalizing, hardening, tempering, solution heat treatment, and precipitation aging, and state which apply to aluminum versus steel.

Match each nondestructive inspection method (dye penetrant, magnetic particle, eddy current, ultrasonic, radiographic) to what it detects and its key limitation.

Describe composite layup, ply orientation, and the common defects found during composite inspection.

Describe tie-down, mooring, and jacking procedures, including the safety precautions and load limits that govern each.

List fueling and defueling precautions covering bonding, static discharge, fuel grade identification, and contamination checks.

Classify corrosion types (galvanic, stress, intergranular, exfoliation, filiform, fretting) by the metal and environmental condition that produces each.

Select the correct removal and treatment method for each corrosion type and state when a structural repair or inspection is required.

Explain protective coatings, primers, sealants, and dissimilar-metal isolation as corrosion prevention measures.

Locate and interpret airworthiness directives, service bulletins, advisory circulars, and type certificate data sheets, and state the regulatory status of each.

Use ATA chapter and section numbering to find a specific procedure in a manufacturer's maintenance manual.

Decide for a stated task whether an AD, service bulletin, or instructions for continued airworthiness govern, and justify the answer.

Draft a maintenance logbook entry and a draft FAA Form 337 for a described repair, including all required signature and description elements.

State the record retention rules and the difference between a maintenance entry and a preventive maintenance entry.

State the privileges and limitations of a mechanic certificate with airframe and/or powerplant ratings, including the rules for supervising unlicensed persons.

Distinguish preventive maintenance under Part 43 Appendix A from other maintenance and identify who may perform and approve each.

Explain the 100-hour, annual, progressive, and recent-experience requirements and who bears return-to-service responsibility in each case.

Identify the limits on major repairs and alterations and the role of the inspection authorization holder.

Re-solve ten mixed weight-and-balance problems under a 25-minute time limit with no arithmetic errors.

Complete two full-length 60-question mixed practice exams under timed conditions with no reference material.

Review every missed item and reduce the weak-topic list to no more than five specific items.

Re-drill each weak topic until scoring 90% or better on a targeted set of ten questions per topic.

Recite from memory the formulas for Ohm's law, weight shift, percent MAC, and the area and volume formulas used on the exam.
