Sample SAR-66 Module 10 Practice Questions

Try these sample questions to test your SAR-66 Module 10 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the primary role of ICAO in relation to Singapore civil aviation regulation?

A.ICAO directly enforces Singapore Air Navigation Regulations on every maintenance organisation

B.ICAO develops International Standards and Recommended Practices that Contracting States such as Singapore implement through national law

C.ICAO issues Singapore Aircraft Maintenance Licences to individual engineers

D.ICAO replaces national regulators whenever an aircraft is registered in a Contracting State

Explanation: ICAO is a UN specialised agency that publishes SARPs through Annexes and documents. Singapore, as a Contracting State, implements these through the Air Navigation Act, Order, Regulations and SARs such as SAR-66 and SAR-145.

2Under the Chicago Convention, who has complete and exclusive sovereignty over the airspace above its territory?

A.ICAO Headquarters in Montreal

B.Each Contracting State

C.The International Air Transport Association

D.The aircraft operator whose fleet is largest in that region

Explanation: Article 1 of the Chicago Convention establishes that every Contracting State has complete and exclusive sovereignty over the airspace above its territory. Singapore implements aviation law within that sovereign framework.

3In Singapore, which statute provides the principal legal basis for civil aviation regulation enforced by CAAS?

A.The Companies Act

B.The Employment Act

C.Regulation (EU) 2018/1139

D.The Air Navigation Act

Explanation: Singapore civil aviation is founded on the Air Navigation Act, under which the Air Navigation Order and Air Navigation Regulations are made. CAAS administers this framework including airworthiness and maintenance personnel licensing.

4The Singapore Air Navigation Order (ANO) primarily serves to:

A.Make detailed provision for matters authorised by the Air Navigation Act, including fees, licensing and operational requirements

B.Replace all SARs so that only the ANO applies to maintenance organisations

C.Grant type certificates for aircraft designs without reference to SAR-21

D.Exempt all Singapore-registered aircraft from airworthiness directives

Explanation: The ANO is subsidiary legislation made under the Air Navigation Act. It contains detailed requirements including examination fees in the Twelfth Schedule and provisions supporting CAAS licensing and oversight.

5Singapore Air Navigation Regulations work together with SARs so that:

A.Only foreign operators must comply with Air Navigation Regulations

B.Regulations apply only to flight crew and never to maintenance personnel

C.Detailed aviation requirements are set out in SARs while the Regulations provide the broader regulatory structure under the Act and Order

D.SAR-66 is an EASA Part-66 copy filed under European Regulations

Explanation: Singapore uses a hierarchy: Act → Order → Regulations → SARs and advisory material. Maintenance personnel and organisations are regulated through this structure, prominently SAR-66 and SAR-145.

6Singapore Aviation Requirements (SARs) issued by CAAS are:

A.Optional guidance leaflets with no legal effect

B.Internal CAAS memos that apply only to CAAS employees

C.Mandatory requirements that specify how aviation activities must be conducted in Singapore

D.Replacements for the Chicago Convention inside Singapore airspace

Explanation: SARs are legally binding requirements published by CAAS covering areas such as certification (SAR-21), airworthiness directives (SAR-39), licensing (SAR-66), approved maintenance organisations (SAR-145) and training (SAR-147).

7A CAAS Advisory Circular (AC) differs from a SAR because an AC:

A.Provides non-mandatory guidance on acceptable means of compliance while the SAR states the requirement

B.Has greater legal force than any SAR and overrides the Air Navigation Act

C.Is issued only by ICAO and adopted verbatim without CAAS review

D.Replaces Airworthiness Directives for all Singapore operators

Explanation: ACs such as AC 66-13 explain how CAAS expects SAR-66 examinations to be conducted. They guide compliance but the underlying obligation remains in the SAR or other regulations.

8CAAS Airworthiness Notices are typically used to:

A.Issue pilot licences for private aeroplane operations only

B.Set airline ticket pricing on routes to Changi Airport

C.Communicate airworthiness information, policy or interpretations relevant to continuing airworthiness and certification

D.Suspend the Chicago Convention within Singapore FIR

Explanation: Airworthiness Notices disseminate CAAS airworthiness policy and technical information to certificate holders, AMOs, operators and maintenance personnel within the Singapore regulatory system.

9CAAS acts as Singapore's aviation authority. In maintenance and continuing airworthiness, CAAS:

A.Approves maintenance organisations, issues AMLs under SAR-66, publishes SARs/ADs and oversees compliance

B.Designs and manufactures all commercial aircraft engines used in Asia

C.Serves as the sole employer of every licensed aircraft engineer in Singapore

D.Delegates all airworthiness functions exclusively to EASA

Explanation: CAAS is responsible for regulatory oversight including SAR-145 AMO approvals, SAR-66 licensing examinations, airworthiness directives and surveillance of continuing airworthiness in Singapore.

10Singapore, as an ICAO Contracting State, must notify ICAO of differences from ICAO Standards. For maintenance personnel licensing this means:

A.Singapore may ignore all ICAO Annexes because SAR-66 is identical to EASA Part-M

B.Contracting States never implement ICAO personnel licensing Standards

C.Only airlines, not CAAS, may notify differences to ICAO

D.Where Singapore SAR-66 differs from ICAO Annex 1 Standards, those differences are notified rather than pretending full harmonisation exists

Explanation: Contracting States implement ICAO Standards through national regulation and file notified differences where their rules diverge. Singapore uses SAR-66, which aligns with ICAO concepts but is a distinct national requirement.

SAR-66 Module 10 Study Tips from Top Performers

1Learn the Singapore stack cold: Air Navigation Act/Order/Regulations → SARs (21/39/66/145/147) → CAAS Advisory Circulars and related notices

2Memorise AC 66-13 Module 10 logistics: 40 questions, 50 minutes, 75% pass — and do not import EASA's 44/55 timings

3Drill SAR-66.30 experience tables: A/B1.2/B1.4 = 3/2/1 years by route; B2/B1.1/B1.3 = 5/3/2 years by route

4Separate mandatory from advisory: Airworthiness Directives are mandatory; Service Bulletins are advisory unless mandated by an AD or other requirement

5Connect SAR-66 and SAR-145: the licence qualifies the person; the AMO authorisation and procedures control when CRS privileges may be exercised

Frequently Asked Questions

What is CAAS SAR-66 Module 10?

Module 10, Aviation Legislation, is a basic knowledge module for the Singapore SAR-66 Aircraft Maintenance Licence. It tests the ICAO/Singapore regulatory framework and airworthiness rules that maintenance certifying staff must apply, with emphasis on SAR-66 and SAR-145.

How many questions are on the official Module 10 MCQ and what is the pass mark?

Per CAAS AC 66-13 (Rev 1), Module 10 is 40 multiple-choice questions in 50 minutes for Categories A, B1 and B2, with a 75% pass mark. Official items have three options; this practice bank uses four options.

Is the M50 essay part of this practice bank?

No. SAR-66 also requires a combined M50 essay paper with questions from Modules 07, 09 and 10. This bank covers only the separable Module 10 MCQ paper.

How long is a Module 10 pass valid?

Under SAR-66, passes in the Module 10 MCQ paper and the M50 essay paper are each valid for 5 years for AML application purposes. Most other basic knowledge module passes are valid for 10 years.

How much does the Module 10 examination cost?

The Air Navigation Order Twelfth Schedule (paragraph 11) sets S$87.20 for each examination paper for an aircraft maintenance licence (from 1 January 2026; previously S$80), with separate fees for cancellation/rescheduling and for licence grant/renewal. Confirm the live fee when booking on the CAAS Examination Portal.

How is Singapore Module 10 different from EASA Part-66 Module 10?

CAAS Module 10 follows AC 66-13 and the Singapore SAR/ANO stack (SAR-21/39/66/145/147). EASA Module 10 uses the EU regulation map and, since 2024, includes Part-IS cybersecurity content that is not the CAAS syllabus focus. Study the Singapore publications for the CAAS exam.

What happens if I fail Module 10 twice quickly?

SAR-66 provides that a person who fails a basic knowledge examination twice within a 3-month period shall be ineligible to reapply for that examination for 3 months.
