AMT content outline and where to practise each area

The content areas below are copied from the official AMT content outline published by Federal Aviation Administration. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through AMT questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: In a 28-volt DC aircraft system, what minimum voltage at the battery indicates a fully charged state?

1. 24.0 volts
2. 25.5 volts
3. 28.0 volts
4. 26.5 volts

Answer: C. 28.0 volts

Explanation:

The correct answer is 28.0 volts. A battery in a 28-volt system that is fully charged reads about its rated voltage when at rest, so 28.0 volts is the best match. The readings of 24.0, 25.5 and 26.5 volts are all below that level. Each one points to a partly charged or discharged battery, so none of them describes a full charge.

The rule to remember: compare a resting battery reading with the system's rated voltage. A reading well under rated voltage means the battery needs charging or testing, and a voltage reading alone is only a starting point, not a full capacity check.

Example 2

Question: During a magneto check at runup, a drop of more than the manufacturer's specified RPM when switching to one magneto indicates:

1. Normal single-magneto operation
2. A possible defective magneto or fouled spark plug on that side
3. The need to adjust ignition timing
4. Excessive advance in the magneto timing

Answer: B. A possible defective magneto or fouled spark plug on that side

Explanation:

The correct answer is a possible defective magneto or fouled spark plug on that side. During the runup check, each magneto is switched to alone, and the engine should lose only a small amount of speed, within the manufacturer's limit. A drop beyond that limit means that ignition side is not firing as well as it should.

Normal single-magneto operation is wrong because a normal drop stays within the limit. Adjusting timing is wrong because an excessive drop is a symptom to investigate first, not an automatic instruction to adjust. Excessive advance is wrong because it is a guess about cause with no support from the symptom.

Rule to remember: an out-of-limit drop points to the ignition system on the side you selected, so inspect its magneto and plugs.

Example 3

Question: A technician installs a new GPS/NAV/COMM system that was not part of the aircraft's original type design. This installation is determined to be a major alteration. Which form is required to be completed and submitted to the FAA to document this work?

1. Airworthiness Directive Compliance Record
2. Malfunction or Defect Report
3. FAA Form 337
4. Aircraft Flight Manual Supplement

Answer: C. FAA Form 337

Explanation:

The correct answer is FAA Form 337. A new GPS/NAV/COMM system that was not part of the original type design, and that is classed as a major alteration, must be documented on Form 337. A copy goes to the owner and another to the FAA.

An Airworthiness Directive Compliance Record is wrong because it records compliance with a directive, not an alteration. A Malfunction or Defect Report is wrong because it reports a service problem, not completed work. An Aircraft Flight Manual Supplement may be needed for operating information, but it is not the form that records and submits the major alteration to the FAA.

Rule to remember: major repairs and major alterations go on Form 337.

How to use these practice tests

Start with a short, untimed pass through the practice set that matches your weakest official content area. Read every explanation, including those for questions you got right, and write down the rule behind each miss rather than the answer itself.

Next, work through the sets that line up with the test you are taking. For the General test, concentrate on regulations, forms, electricity, materials, corrosion, weight and balance, and drawings. For Airframe, add structures, sheet metal, hydraulics and landing gear. For Powerplant, add engine theory, ignition, fuel metering, propellers and turbine principles.

Pair each practice session with the official material. After a miss, look up the related regulation, publication or handbook section and read the surrounding text, since real test questions can be worded differently from ours. Our questions are written by us and are not real exam questions, so use them to find gaps, not to predict the test.

Do your maths and weight and balance by hand until the steps are routine. Before booking, take a mixed set with no notes, review what went wrong, and repeat only the topics that still cost you answers. Check the FAA pages for current eligibility and scheduling details before you book.
