Read and record measurements from each instrument type to its stated resolution, converting between metric and imperial units.

Compute allowance, maximum/minimum clearance and interference for a set of shaft-and-hole pairs.

Classify each pair as a clearance, transition or interference fit, and state a representative aircraft application for each.

State the handling, cleaning, calibration and storage requirements for precision measuring tools.

Identify solid, blind, hi-lok and special fastener types from their part-number coding and state the installation sequence for a solid rivet joint.

Calculate rivet length, pitch and edge distance for a given sheet stack and select the correct rivet diameter.

Diagnose loose, over-driven, under-driven, tilted and clinched rivets from a written description and state the corrective action.

Distinguish rigid pipe from flexible hose by markings, pressure rating and temperature limit, and state the inspection criteria for each.

Describe the fabrication of a rigid pipe: cutting, deburring, bending to minimum radius, flaring and proof-pressure testing, and the correct fitting torque for a flexible hose B-nut.

Identify tension, compression and torsion spring types and state the inspection criteria for set, cracks, corrosion and end-condition.

Classify ball, roller, needle, thrust and plain bearings, and describe their installation, removal, lubrication and inspection points.

Describe the construction, swaging, tensioning and inspection of aircraft control cables, including turnbuckle locking and rigging checks.

Identify gear, belt, chain, shaft and spline transmission elements and state the checks for backlash and end-float.

Interpret orthographic and section views, dimensioning, tolerance callouts and standard symbols on an engineering drawing.

State the identification, storage and handling requirements for aluminium alloys, steels, titanium, composites and shelf-life consumables such as sealants and adhesives.

Compare welding, brazing and soldering by working temperature, filler, flux and joint mechanism, and state where each is used on an aircraft.

Identify weld and brazed-joint defects (porosity, cracking, lack of penetration, undercut) and name the inspection or NDT method that reveals each.

Describe a soldered electrical connection procedure from surface preparation through tinning, heat control and final inspection.

Describe annealing, solution treatment and ageing of aluminium alloys and decode temper designations.

Explain the scope of EWIS, why dedicated EWIS maintenance practices exist and how EWIS degradation contributes to accidents.

Identify wire types, cable construction, current and temperature ratings, and the marking and coding used to identify aircraft wires.

State the installation requirements for conduit, clamps, stand-offs and spacers, including minimum bend radius, separation from hot surfaces and support spacing.

Describe the correct stripping, crimping, splicing and terminating procedures and the acceptance criteria for each.

Recognise chafing, arcing, corrosion and contamination damage and state the repair or replacement decision for each.

Define datum, arm, moment, basic empty weight, MTOW and MLW, and convert between them in a worked loading problem.

Perform a full weight-and-balance calculation for a loaded aircraft and check the result against forward and aft CG limits.

Describe weighing procedure, weighing points, scale calibration and the effect of an equipment change on the W&B schedule.

Describe jacking, towing, taxiing and mooring, stating the safety precautions and the personnel and equipment required for each.

Describe preservation and storage of airframe, engine and systems, and the maintenance actions needed before return to service.

Sequence a maintenance task through disassembly, cleaning, inspection, repair, reassembly, functional test and certification, including the documentation raised at each step.

Sit two full-length timed mock exams under exam conditions and record the score for each domain separately.

Re-study every domain scoring below 75%, working from the weak-topic list produced by the mocks.

Re-derive from memory the clearance/interference formulae, the rivet-length formula and the moment/CG equations.

Recite without notes the safety-critical rules for fuel, oxygen, hydraulic and electrical isolation and for fire extinguisher selection.
