Sample EASA Module 7 Practice Questions

Try these sample questions to test your EASA Module 7 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1When servicing an aircraft oxygen system, why is it critical that no oil, grease, or hydrocarbon contamination contacts the components?
A.Oil residue absorbs oxygen and reduces the available flow rate to the masks
B.Hydrocarbons in contact with high-pressure oxygen can ignite or react violently, causing fire or explosion
C.Grease increases the dielectric strength of the line and causes static discharge
D.Oil causes the oxygen regulator diaphragm to swell and stick open
Explanation: Oxygen is a powerful oxidiser; if escaping or pressurised oxygen contacts hydrocarbons such as oil or grease, the result can be a violent fire or explosion, so all tools, hands, and components must be kept grease-free.
2An electrical fire breaks out in an avionics rack. Which extinguishing agent is most appropriate because it is electrically non-conducting and leaves no residue?
A.Water (Class A agent)
B.Halon / clean-agent (or CO2) suitable for Class C electrical fires
C.Foam (AFFF)
D.Dry chemical powder (ABC)
Explanation: Class C (electrical) fires require a non-conductive, clean agent. Halon (e.g. Halon 1211) and CO2 are electrically non-conducting and leave no residue, making them suitable for energised electrical equipment.
3Before working on an aircraft electrical circuit, the FIRST safety action a technician should normally take is to:
A.Apply external ground power to keep the busbars energised for testing
B.Discharge any capacitors by short-circuiting them to the airframe with a screwdriver
C.Connect a multimeter across the busbar to read the live voltage
D.Isolate the supply by disconnecting/removing the battery and tagging the circuit as inoperative
Explanation: Safe working practice with electricity requires isolating the supply first: disconnect/remove the battery (and any external power) and apply warning tags/placards before working on the circuit.
4A Class B fire on an aircraft involves which of the following?
A.Flammable liquids such as fuel, oil, hydraulic fluid, and solvents
B.Ordinary combustibles such as paper, wood, and fabric
C.Energised electrical equipment and wiring
D.Combustible metals such as magnesium
Explanation: Class B fires involve flammable liquids and gases such as fuel, oil, hydraulic fluid, and solvents. The agent must smother or interrupt combustion of the liquid.
5When handling solvents and chemical cleaning agents in the workshop, the primary purpose of consulting the Safety Data Sheet (SDS/MSDS) is to:
A.Determine the shelf-life expiry date for stores accounting
B.Find the manufacturer's part number for re-ordering
C.Identify the hazards, required personal protective equipment, and first-aid/spill measures for the substance
D.Establish the correct torque value for the container cap
Explanation: The Safety Data Sheet provides hazard identification, handling and storage precautions, required PPE, exposure controls, and first-aid and spill response measures for a chemical substance.
6A CO2 fire extinguisher should be used with caution in a confined cockpit or cabin space primarily because:
A.It conducts electricity and may re-ignite the fire
B.It displaces oxygen and can cause asphyxiation of personnel in the enclosed space
C.It leaves a thick corrosive residue on avionics
D.Its discharge temperature can melt aluminium structure
Explanation: CO2 extinguishes by displacing oxygen; in a confined space this oxygen depletion creates an asphyxiation hazard for personnel, so ventilation and caution are required.
7Under good workshop tool-control practice, a 'shadow board' or tool-control system is used principally to:
A.Display the calibration due dates of all measuring instruments
B.Account for every tool so that none is inadvertently left in an aircraft as a foreign object
C.Indicate which tools require electrical PAT testing
D.Show the maximum torque rating of each spanner
Explanation: Tool control (shadow boards, tool tallies, inventories) ensures every tool is accounted for before and after a task, preventing tools being left in the aircraft as a foreign object debris (FOD) hazard.
8A precision tool such as a micrometer or torque wrench must be calibrated against standards that are:
A.Set by the individual technician's experience
B.Traceable to national/international measurement standards within a defined calibration interval
C.Re-zeroed only when the tool is visibly damaged
D.Established by comparing two uncalibrated tools of the same type
Explanation: Calibration must be traceable to recognised national/international standards and performed at defined intervals so the instrument's accuracy is assured and documented.
9A click-type torque wrench has just been used to apply a high torque value. To preserve its calibration when storing it, the technician should:
A.Leave it set at the maximum value to keep the spring exercised
B.Store it set at the value last used so the next user sees the setting
C.Wind the setting back to the lowest scale value (but not fully to zero unless the manufacturer specifies) before storage
D.Lubricate the internal spring with light oil before storage
Explanation: Storing a click-type torque wrench at the lowest scale setting relaxes the internal spring and helps maintain calibration; leaving it set high keeps the spring loaded and can cause drift over time.
10On a metric micrometer with a 0.5 mm pitch thimble and a 50-division thimble scale, one division on the thimble represents:
A.0.001 mm
B.0.01 mm
C.0.1 mm
D.0.5 mm
Explanation: The spindle advances 0.5 mm per revolution; with 50 thimble divisions, each division equals 0.5 / 50 = 0.01 mm.

About the EASA Module 7 Exam

EASA Part-66 Module 7 (Maintenance Practices) is a core module of the European aircraft maintenance licence, taken by Category A, B1, and B2 candidates. It covers the hands-on practices of aircraft maintenance: safety precautions, workshop and tool practices, engineering drawings, fits and clearances, riveting, pipes and hoses, bearings and transmissions, electrical wiring (EWIS), weight and balance, aircraft handling and storage, non-destructive testing, and maintenance procedures. Under Commission Implementing Regulation (EU) 2023/989 (applicable 12 June 2024) the former 7A/7B split was merged into a single Module 7, and it is now the only module that still includes essay questions.

EASA Module 7 Study Tips from Top Performers

1Memorise the riveting numbers: minimum edge distance not less than 2D (twice the rivet shank diameter) and the standard AN/MS tube flare angle of 37 degrees (not the 45-degree automotive flare)
2Learn NDT method selection cold: penetrant finds only surface-breaking flaws on non-porous metals, magnetic particle works only on ferromagnetic steels, eddy current finds surface/near-surface cracks in conductors, and ultrasonic/radiographic find internal defects
3Remember the oxygen rule: no oil, grease, or hydrocarbons near oxygen systems because contact with high-pressure oxygen can ignite violently; keep tools, hands, and components grease-free
4Practise weight and balance: moment = mass x arm measured from the datum, and the CG must lie within the published forward and aft limits; redistribute payload or add approved ballast if it does not
5Know the torque traps: applying a dry-specified torque to lubricated threads over-tightens the bolt, and a lever-extension adapter requires the wrench setting to be recalculated
6Store a click-type torque wrench wound back to its lowest scale setting to relax the spring and preserve calibration, and only calibrate against standards traceable to national measurement standards

What changed with Regulation (EU) 2023/989?

Applicable from 12 June 2024, the regulation merged former sub-module splits (7A/7B became a single Module 7, 9A/9B became 9, and so on) and deleted sub-module 7.4. Pre-2024 courses must complete under the old standard by 12 June 2026; new candidates study the merged syllabus.

How many attempts are allowed at a module?

A candidate may take a maximum of three consecutive attempts at the same module, with a 90-day waiting period before re-sitting after a fail. Examination credit is generally valid for 10 years.

Does the real exam use 3 or 4 options?

The real EASA Part-66 multiple-choice exam uses 3-option questions. This free practice bank uses 4 options to broaden distractor learning; the underlying rules, values, and standards are identical to the real exam.

What edge distance and flare angle should I memorise?

Rivet edge distance (centre of rivet to sheet edge) is generally not less than 2D (twice the rivet shank diameter), and the standard AN/MS aircraft tube flare is 37 degrees. These are common Module 7 exam values.
