CAA NZ AME Aeroplanes 1 (Subject 4) study guide
CAA NZ AME Aeroplanes 1 (Subject 4) · Work through your exam, one topic at a time.
Aeroplanes 1 (Subject 4) is one of the technical subject examinations that the Civil Aviation Authority of New Zealand administers for the Part 66 aircraft maintenance engineer licence. It is aimed at engineers who are building or extending an aeroplane (fixed-wing) licence and who need to demonstrate a broad, systems-level understanding of airframes and powerplants rather than a type-specific knowledge of one aircraft. The CAA NZ AME Aeroplanes 1 (Subject 4) study guide has 6 sections and about 1,834 words.
01Aeroplane Airframe Structures and Systems
The skin is a stressed member: it carries shear and, in a pressurised fuselage, hoop and longitudinal tension. Stringers run fore-aft and carry bending; frames (rings) run circumferentially, hold the cross-section shape and stabilise the stringers against buckling; bulkheads pick up concentrated loads such as wing attachment, engine mounts and pressure bulkheads.

Mineral fluid MIL-H-5606 (red dye) is the traditional light-aircraft fluid; MIL-H-83282 is a less flammable synthetic; phosphate-ester fluid such as Skydrol (purple) is used on transports and needs EPR/EPDM seals, not natural rubber or nitrile. Never mix fluid types.

Light aeroplanes use 14 V or 28 V DC; larger types add 115 V AC at 400 Hz. A DC generator needs a reverse-current cut-out; an alternator uses rectifier diodes and is largely self-limiting.

Primary controls are aileron, elevator and rudder; secondary are flaps, slats, spoilers and trim. Cable systems use turnbuckles, fairleads and pulleys, with tension checked against the manual at a stated temperature and re-checked after rigging.

Engine mounts and isolators carry thrust and torque; dynafocal mounts align the mount legs with the engine's centre of gravity. The firewall and firewall shutoff valve, baffles and cowl flaps control cooling and fire containment.

In New Zealand, Part 43 governs aircraft maintenance, Part 66 licensing, Part 91 operations and Part 39 airworthiness directives. An AD is mandatory: record the method, date and hours or cycles of compliance and the next due point.
