Aircraft Maintenance Engineering (AME) Course Syllabus: DGCA B1 & B2 Modules

AME Course Syllabus at a Glance

AME course syllabus is divided into different modules, which is based on selected licence  category. It includes theoretical knowledge with practical training which helps students to understand aircraft systems and maintenance procedures.

Here is a table given below providing a quick overview of AME course duration, training hours, eligibility, categories, subjects and assessment structure. It shows necessary basic requirements to be followed as per DGCA CAR-66 and CAR-147.

How the AME Course Syllabus Is Structured

You study AME through subject modules and practical training. A module is a set of lessons on one subject, such as aircraft materials or maintenance practices.

• Subjects: Your category determines what you study. CAR-66 lists the required modules and the depth of knowledge needed for each topic. [1]
• Learning: At a CAR-147 approved institute, you attend lessons and practise tasks in workshops and maintenance facilities. [2]
• Teaching schedule: Your institute follows an approved programme. It must cover the requirements for its approved category. [2]

DGCA CAR-66 Module List for B1 and B2

DGCA CAR-66 have different types of AME licence categories every category has their specific modules. Modules 3 to 10 are common in all categories, while Modules 11 to 17 are specified as per aircraft type, engine and maintenance specialisation. This module structure helps students understand which subjects they need to study for their selected AME category.

Here is a table given below providing an overview of applicable modules on B1.1, B1.2, B1.3, B1.4 and B2 categories. The table makes it easier to compare the syllabus requirements of B1 mechanical categories with the B2 avionics category. Use the column for your category to see which modules apply. Modules 3–10 are common to all five categories shown below. Specialist modules depend on the aircraft and systems covered. [1]

Key: ✓ Applicable · — Not applicable · N/A: Not applicable in the cited CAR-66 edition. [1]

Common Subjects in the AME Course

The common modules build the knowledge you use throughout training. These examples show how the subjects connect with learning activities. [1]

These are learning examples. Actual practical tasks follow the institute’s approved training programme. [1][2]

Why are Modules 1 and 2 marked N/A?

Mathematics and Physics appear in the module list, but the cited edition marks them as not applicable. It does not require separate DGCA module examinations for these two subjects. You still use maths and physics when studying aircraft systems and maintenance. [1]

Understanding Module Knowledge Levels

For example, B1 and B2 both include Electronic Fundamentals. B2 requires more detail in certain electronic topics. These levels describe depth of knowledge. They are not course years or licence grades. [1]

AME B1 Mechanical Syllabus

AME B1 Mechanical syllabus includes aircraft structures, engines and technical knowledge related to systems. In this students understand the working, inspection and maintenance requirements of aircraft components. Students learn to understand the connection between different aircraft systems and how they operate. It also explains identifying common faults and work according to approved maintenance instructions and focus on safety procedures and standard maintenance practices.

The main subject areas include:

• Aircraft structures: The aircraft body, wings and other structural parts. You study their construction, materials and common damage.
• Aircraft engines: Turbine or piston engines, including fuel, lubrication and supporting systems.
• Mechanical systems: Landing gear, brakes, hydraulics and flight controls. You study their operation and maintenance.
• Electrical systems: Aircraft power generation, batteries, wiring and electrical components. Electrical subjects are also part of B1 training.

Your B1 subcategory determines whether you focus on aeroplanes or helicopters, and turbine or piston engines. [1]

B1.1 — Turbine Aeroplanes

B1.1 focuses on jet and turbine engine aeroplanes. students learn about how their structures, engines and systems work together. The specialist subjects include Aeroplane Aerodynamics, Structures and Systems (Module 11), Gas Turbine Engines (Module 15) and Propeller (Module 17). [1] Topics include landing gear, hydraulics, engine operation and propeller systems. Topics include how a jet engine produces thrust and how a turboprop engine drives a propeller. For example, you may identify the compressor, combustion section and turbine on an engine model.

B1.2 — Piston Aeroplanes

B1.2 focuses on piston-powered aeroplanes. Students learn about the aircraft’s structure, systems, engine and propeller. The specialist subjects are Aeroplane Aerodynamics, Structures and Systems (Module 11), Piston Engine (Module 16) and Propeller (Module 17). [1] Students learn how pistons turn the crankshaft. Lessons also cover fuel, ignition, cooling and lubrication systems, plus propeller construction and control. For example, you may use a diagram to follow the movement of air and fuel through an engine.

B1.3 — Turbine Helicopters

B1.3 focuses on turbine-powered helicopters. You learn how rotating blades produce lift and how the engine powers the rotor system. The specialised subjects include Helicopter Aerodynamics, Structures and Systems (Module 12) and Gas Turbine Engines (Module 15). [1] Topics include rotor controls, transmission, helicopter structures and vibration. You also study turbine engines and their supporting systems. A training model can help you trace how power travels from the engine through the transmission to the main rotor.

B1.4 — Piston Helicopters

B1.4 focuses on piston-powered helicopters. You study how helicopter systems work with a piston engine. The specialist subjects are Helicopter Aerodynamics, Structures and Systems (Module 12) and Piston Engine (Module 16). [1] Lessons cover rotor controls, transmission, aircraft structures and engine operation. Engine topics include fuel supply, ignition, cooling and lubrication. For example, you may identify these systems on a training engine and explain their functions. This helps you understand how the engine supports helicopter operation.

AME B2 Avionics Syllabus

The B2 Avionics syllabus explains aircraft electrical and electronic systems. You learn how equipment receives power and processes information. You also study systems that help pilots communicate, navigate and monitor the aircraft. Alongside the common modules, you study Aircraft Aerodynamics, Structures and Systems (Module 13) and Propulsion (Module 14). [1]

The main subjects include:

• Electrical systems: Generators, batteries, wiring and power distribution. You learn how electricity reaches aircraft equipment.
• Electronics and digital systems: Circuits, components and data signals. You learn how equipment processes information.
• Instruments: Sensors and displays that show airspeed, altitude and other operating information.
• Communication: Radios that allow pilots to speak with air traffic control.
• Navigation: Equipment that helps determine the aircraft’s position and follow its route.
• Automatic flight control: Autopilot systems and their connections with other aircraft systems.

Propulsion subjects include engine basics, electronic engine controls, engine indications, starting and ignition systems. For example, you learn how a sensor sends an engine-temperature reading to a cockpit display. [1] Practical exercises connect these subjects with wiring diagrams, test equipment and fault-finding.

Is the AME Syllabus Semester-Wise or Module-Wise?

The DGCA AME syllabus is module-wise. Institutes may arrange the modules into semesters under their approved training schedule. [1][2]

• A module defines what you study. For example, Electrical Fundamentals is Module 3.
• A semester organises when you study. It may include lessons from several modules, workshops and practical sessions.

The order of subjects and practical sessions can differ between institutes. Your institute’s approved timetable shows when you cover each part. Your category still determines the required modules and knowledge levels. [1][2]

AME Semester-Wise Syllabus: Example from Falcon Institute of AME

At Falcon Institute of AME (FIAME), Sonipat, the B1.1, B1.3 and B2 basic training courses follow a two-year schedule with four semesters of six months each. Every semester includes theory and practical learning. [7]

The tables below summarise Falcon’s Maintenance Training Organisation Exposition (MTOE), the document describing the institute’s training arrangements. They show how an institute can divide CAR-66 subjects across semesters. Other institutes may follow a different teaching order. M means Module. Parts I, II and III are teaching divisions used by Falcon. They are not separate DGCA modules.

B1.1: Turbine Aeroplanes

B1.3: Turbine Helicopters

B2: Avionics

For each category, Falcon’s schedule includes 1,440 hours of theory and 960 hours of practical training. The semester totals include practical sessions at the institute and, where scheduled, contracted aircraft maintenance organisations. [7]

Practical Training in the AME Course

Practical training helps you apply classroom learning. You work under supervision with tools, components and systems relevant to your category. Sessions take place in workshops and maintenance facilities under the approved programme. [2] For example, an electrical lesson may be followed by a supervised exercise using a multimeter on a training circuit. The activities below build these skills step by step.

Workshop Skills and Tool Handling

You learn to use tools accurately and handle components carefully. Tasks include taking measurements, selecting suitable equipment and following safe working procedures. Activities may involve measuring instruments, a torque wrench or electrical connectors. You learn to check tool condition, keep the work area clean and protect components from damage. Instructors supervise the tasks and assess how safely and correctly you perform them. [2]

Aircraft Inspection, Testing and Troubleshooting

You learn to recognise defects and check system operation. Tasks match your category and training stage. You also practise removing, fitting or adjusting selected components under supervision. Troubleshooting involves following instructions, taking readings and using the results to investigate a fault step by step. [1][2]

• B1 examples: Inspect a component for corrosion, examine a hose for damage or check a mechanical linkage.
• B2 examples: Follow a wiring diagram, check connections or test a training circuit.

Maintenance Manuals, Records and Assessments

You learn to find the correct maintenance instructions and follow the steps, precautions and limits. After the task, you record the work completed, measurements and defects found. Practical assessments check whether you can demonstrate these skills. Assessors observe your tool use, inspection work, component handling and attention to safety. [2] Course practical training does not automatically count as the maintenance experience required for licensing. Any experience claimed must meet CAR-66 requirements and be properly documented. [1]

Falcon MRO Training in the AME Course

During an AME course, you learn in classrooms, workshops and aircraft maintenance facilities. MRO means Maintenance, Repair and Overhaul. Training in this environment helps you understand how maintenance teams inspect aircraft, follow instructions and work safely. For example, Falcon Institute of AME assigns 30% of its practical training to contracted, approved Aircraft Maintenance Organisations (AMOs). This training is included in the basic course. [7]

How Many Hours of MRO Training Are Included?

Falcon’s MTOE gives the following training hours for B1.1, B1.3 and B2:

The course includes 960 practical hours. Of these, 30% equals 288 hours at the contracted maintenance organisations. These hours are part of the total course training. [7]

What Will You Learn During Practical Training?

You connect the subjects you study with supervised maintenance tasks. Depending on your category and training plan, you learn to:

• Follow maintenance instructions and safe working procedures.
• Identify aircraft systems and components.
• Use the tools and equipment needed for assigned tasks.
• Record your practical work and demonstrate what you have learned.

The detailed tasks follow Falcon’s training arrangements with the maintenance organisation. [7]

FIAME’s MRO and Practical Training Partners

Falcon’s MTOE lists practical trainers and assessors from these organisations: [7]

Your training location depends on your category and the institute’s training schedule. Students do not necessarily train at every organisation listed.

This practical training helps you complete the course. You must also meet the applicable examination and maintenance experience requirements to obtain a DGCA AME licence.

AME Course Assessments and DGCA Module Examinations

Assessments check what you know and what you can do practically. Each has a different purpose.

Questions and examination duration depend on the module and category. Prepare using the applicable syllabus and knowledge levels. [1]

Completing the course does not automatically give you an AME licence. Your training certificate records the elements completed. DGCA licensing also requires the applicable knowledge, maintenance experience and application conditions to be met. [1][2]

You need a computer number through Pariksha before applying for DGCA module examinations. For registration, documents and application steps, read the official DGCA AME Examination FAQs. [3]

Books and Study Resources for AME Students

Start with CAR-66 and your institute’s course materials. Use supplementary books to understand concepts, study diagrams and revise relevant topics.

FAA handbooks are free on the official FAA website. These handbooks and commercial textbooks support your learning, but may follow different regulatory systems. Match their chapters to your CAR-66 syllabus. Use DGCA references for Indian regulatory requirements.
