32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Ohm's law
- E = I × R. Voltage in volts equals current in amperes multiplied by resistance in ohms; used to solve for any single unknown in a DC circuit.
- Series circuit current
- In a series circuit, current is identical through every component, total resistance is the sum of the resistances, and voltage drops add to the applied voltage.
- Parallel circuit resistance
- Total resistance in a parallel circuit is always less than the smallest branch resistance; voltage across each branch is equal and the branch currents add.
- Title block
- A block normally in the lower right corner of a drawing that gives the drawing number, scale, date, and current revision status.
- Hidden lines
- Short dashes drawn on a drawing to show edges or surfaces that are not visible in the view being presented.
- Assembly drawing
- A drawing that shows the relationship and location of two or more parts and includes a bill of materials listing those parts.
- Datum
- A fixed reference point, such as the firewall or wing leading edge, from which all weight arms are measured; arms forward of it are negative.
- Moment
- The product of a weight and its arm, usually expressed in pound-inches; moments are totaled and divided by total weight to locate the CG.
- Tare weight
- The weight of blocks, chocks, or slings used to support an aircraft on scales; it must be subtracted from each scale reading.
- Flare angle
- Standard aircraft AN and MS tube fittings use a 37-degree flare; a 45-degree automotive flare or nut must never be substituted.
- Flareless fitting
- A fitting that uses a ferrule preset onto the tubing; it is rated for high pressure, and the ferrule cannot be reused on another tube.
- Lay line
- A lengthwise stripe molded into flexible hose that shows whether the hose is twisted during installation; it must stay straight, not spiral.
- Alclad
- Aluminum sheet clad with a thin layer of commercially pure aluminum to protect a high-strength core alloy such as 2024 from corrosion.
- Magnetic particle inspection
- A nondestructive test using magnetic flux and iron particles to reveal surface and near-surface defects, but only on ferromagnetic materials such as steel.
- Solution heat treatment
- Heating an alloy to a specified temperature to dissolve alloying elements, then quenching; later natural or artificial aging develops the strength.
- Bonding before fueling
- Connect the fuel source to the aircraft first, then ground the aircraft, so static electricity cannot arc and ignite fuel vapor.
- Jacking an aircraft
- Use only approved jack points, keep the aircraft level and within its jacking CG limits, and install safety stands before working beneath it.
- Towing limits
- Never turn a nosewheel beyond its published turning limits, and always use a tow bar equipped with a shear pin to prevent structural damage.
- Galvanic corrosion
- Corrosion between two dissimilar metals joined in the presence of an electrolyte, in which the less noble metal becomes anodic and is eaten away.
- Exfoliation
- An advanced form of intergranular corrosion that lifts layers of rolled or extruded aluminum, causing flaking and blistering of the surface.
- Alodine conversion coating
- A chemical treatment applied to bare aluminum after corrosion removal that forms an oxide film and improves paint adhesion and corrosion resistance.
- Pythagorean theorem
- For a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides, written as a² + b² = c².
- Horsepower
- One horsepower equals 33,000 foot-pounds per minute, or 550 foot-pounds per second, or 746 watts of electrical power.
- Temperature conversion
- Degrees Fahrenheit equals degrees Celsius times 9/5 plus 32; degrees Celsius equals degrees Fahrenheit minus 32, times 5/9.
- FAA Form 337
- The form used to record a major repair or major alteration; a copy is submitted to the FAA and one is kept with the aircraft records.
- FAR 43.9 entry
- A maintenance record must state the work performed, the date completed, and the name, certificate type and number, and signature of the person.
- Airworthiness Directive record
- Each AD compliance entry must show the AD number, the method of compliance, the date, and the aircraft total time in service.
- Advisory Circular
- FAA guidance material that is not mandatory; AC 43.13-1B gives acceptable methods, techniques, and practices for aircraft inspection and repair.
- Type Certificate Data Sheet
- An FAA document listing the approved operating limitations, specifications, and eligible equipment for an aircraft, engine, or propeller type design.
- Inspection Authorization
- A rating added to a mechanic certificate that lets the holder perform annual inspections and approve major repairs and alterations for return to service.
- FAR 65.83 recency
- A mechanic must have had at least 6 months of practical experience within the preceding 24 months in the type of work performed to use the rating.
- Preventive maintenance
- Simple, minor preservation and replacement work listed in FAR Part 43 Appendix A that a certificated mechanic or qualifying pilot may perform.
