1. 1What is ICAO's role in developing the framework for international civil aviation?

   1. A.Issuing each airline's national air operator certificate
   2. B.Developing mutually recognised technical standards with statesCorrect answer: B
   3. C.Approving each maintenance organisation's local exposition
   4. D.Granting individual engineers their national maintenance licences

   Explanation: ICAO states, "We assist governments with the development of mutually recognized technical standards and global plans." This describes its international standard-setting role. Individual operator, organisation and personnel approvals belong to the applicable regulatory authorities.

2. 2Which aircraft category is covered by a Part-66 B1.1 licence?

   1. A.Piston-engine aeroplanes
   2. B.Turbine-engine helicopters
   3. C.Piston-engine helicopters
   4. D.Turbine-engine aeroplanesCorrect answer: D

   Explanation: 66.A.3(b) identifies "B1.1 Aeroplanes Turbine". Piston aeroplanes are B1.2, turbine helicopters B1.3 and piston helicopters B1.4; these are distinct subcategories.

   Reference: UK Continuing Airworthiness Regulation — 66.A.3(b), p.615

3. 3What authority must the accountable manager of a Part-145 organisation have?

   1. A.Authority to waive airworthiness directives for commercial reasons
   2. B.Authority to grant aircraft type ratings without CAA endorsement
   3. C.Corporate authority to finance and carry out compliant maintenanceCorrect answer: C
   4. D.Corporate authority to issue design approvals for any aircraft repair

   Explanation: 145.A.30(a) requires "corporate authority to ensure that all maintenance activities of the organisation can be financed and carried out" in accordance with the applicable regulation. That responsibility does not permit AD waivers, licence endorsements or unrestricted design approvals.

   Reference: UK Continuing Airworthiness Regulation — 145.A.30(a), pp.417–418

4. 4When must an operator obtain the CAA air operator certificate required by ORO.AOC.100(a)?

   1. A.Before commencing commercial air transport operationsCorrect answer: A
   2. B.After completing the first month of commercial operations
   3. C.When the first aircraft's initial airworthiness review expires
   4. D.After the first commercial flight has demonstrated demand

   Explanation: ORO.AOC.100(a) requires the operator, "prior to commencing commercial air transport operations", to apply for and obtain its AOC. It is a prerequisite to starting, not an approval deferred until revenue service, demand testing or an airworthiness-review event.

   Reference: UK Air Operations Regulation (EU) No 965/2012 — ORO.AOC.100(a), p.365

5. 5What is the role of the drawings and specifications included in a product's type design under 21.A.31(a)(1)?

   1. A.To record the maintenance history of each individual aircraft
   2. B.To establish the operator's dispatch-deferral procedures
   3. C.To specify only the flight crew's normal operating procedures
   4. D.To define the product configuration and design featuresCorrect answer: D

   Explanation: 21.A.31(a)(1) describes drawings and specifications as "necessary to define the configuration and the design features of the product". Their type-design function is to define configuration and design features, rather than to serve as an individual maintenance history, MEL dispatch procedure or crew operating manual.

   Reference: UK Initial Airworthiness Regulation (EU) No 748/2012 — 21.A.31(a)(1), p.135

6. 6Which description captures continuing airworthiness as defined in Regulation (EU) No 1321/2014?

   1. A.The initial design-certification process establishing a new aircraft type's compliance
   2. B.The performance of scheduled maintenance tasks alone, excluding other compliance processes
   3. C.The pre-flight inspection alone establishing condition immediately before a departure
   4. D.The ongoing processes maintaining applicable compliance and safe condition throughout operating lifeCorrect answer: D

   Explanation: Article 2(d) defines continuing airworthiness as "all of the processes ensuring that, at any time in its operating life, the aircraft complies with the airworthiness requirements in force and is in a condition for safe operation". Initial design certification is a different process; scheduled task performance and a pre-flight inspection are each narrower than the full continuing process.

   Reference: UK Continuing Airworthiness Regulation — Article 2(d), p.47

7. 7What distinguishes an airworthiness directive under 21.A.3B(a) from an advisory maintenance recommendation?

   1. A.It recommends an optional improvement whose adoption the operator may freely decline
   2. B.It approves a design change but leaves compliance with its safety actions voluntary
   3. C.It mandates actions to restore an acceptable level of safetyCorrect answer: C
   4. D.It records completed maintenance without imposing any corrective requirement

   Explanation: 21.A.3B(a) describes an AD as a document that "mandates actions to be performed on an aircraft to restore an acceptable level of safety". Mandatory corrective action distinguishes it from an optional recommendation, a design approval considered on its own or a maintenance completion record.

   Reference: UK Initial Airworthiness Regulation (EU) No 748/2012 — 21.A.3B(a), p.60

8. 8Who has sovereign responsibility for interpreting and implementing ICAO standards within a state's regulatory framework?

   1. A.The individual aircraft's type-certificate holder
   2. B.The operator's contracted maintenance organisation
   3. C.The international airline industry associations
   4. D.The relevant authorities of the state concernedCorrect answer: D

   Explanation: ICAO identifies this as "a sovereign regulatory responsibility of state authorities." International provisions are implemented through state regulatory frameworks; manufacturers, maintenance contractors and industry associations do not acquire sovereign authority through their technical roles.

9. 9Which avionics work falls within the Part-66 B1 licence privileges, assuming the relevant aircraft rating and other certification conditions are met?

   1. A.Troubleshooting intermittent avionics faults using complex tests
   2. B.Work requiring only simple serviceability tests without troubleshootingCorrect answer: B
   3. C.Approval of a new avionics installation's certification design
   4. D.Repair of any avionics component regardless of its workshop rating

   Explanation: 66.A.20(a)(2) includes "work on avionic systems requiring only simple tests to prove their serviceability and not requiring troubleshooting." Complex troubleshooting exceeds that B1 provision. A B1 licence also does not itself confer design approval or unrestricted component-workshop privileges.

   Reference: UK Continuing Airworthiness Regulation — 66.A.20(a)(2), p.621

10. 10Before issuing or reissuing a normal certification authorisation, what must a Part-145 organisation assess under 145.A.35(f)?

    1. A.The employee's competency, qualifications and capability for the intended dutiesCorrect answer: A
    2. B.The employee's length of service, without assessing the intended certifying duties
    3. C.The employee's experience on another aircraft type, without checking current competence
    4. D.The employee's licence validity alone, without assessing capability for the intended duties

    Explanation: 145.A.35(f) requires assessment of "competency, qualifications and capability to carry out their intended certifying duties". Seniority, experience elsewhere or licence validity alone does not replace assessment of suitability for the intended certification duties. The question excludes the specified unforeseen-case exception.
