What is the Part 66 Licence and Why is it Important? The EASA Part 66 and UK CAA Part 66 licenses are internationally recognized qualifications for aircraft maintenance engineers, certifying that you have the necessary knowledge and experience to maintain and release aircraft to service. There are three main categories under Part 66: Category A permits you to certify specific maintenance tasks after passing relevant modules and gaining experience. Ideal for those focusing on line maintenance tasks. A1: Turbine Engined Aeroplanes, A2: Piston Engined Aeroplanes, A3: Turbine Engined Helicopters, A4: Piston Engined Helicopters. Category B allows the engineer to sign the Certificate of Release to Service for the aircraft in the category for which they are licensed after passing all required modules and acquiring hands-on experience. B1.1: Turbine Engined Aeroplanes, B1.2: Piston Engined Aeroplanes, B1.3: Turbine Engined Helicopters, B1.4: Piston Engined Helicopters, B2: Avionics, B3: Piston-engine non-pressurized aircraft under 2,000 kg. Category C authorizes certification following base maintenance on aircraft, requiring extensive experience across different categories.

Understanding Part 66 Exam Lengths and Structure

Each Part 66 module exam varies in length and complexity depending on the category of your license (A, B1, B2, B3). The exams consist of multiple-choice questions and, for some modules, essay questions.

For example, Mathematics (Module 1) for Category A includes 16 multiple-choice questions with a 20-minute time limit, while Category B1 and B2 have 32 questions over 40 minutes. More complex modules, like Aircraft Aerodynamics, Structures, and Systems (Module 13), can have up to 180 questions over 225 minutes for Category B2 candidates.

Modules that include both multiple-choice and essay questions—such as Maintenance Practices (Module 7) and Human Factors (Module 9)—have separate time allocations for each section. For instance, Category B1 candidates taking Maintenance Practices will have 100 minutes for multiple-choice questions and an additional 40 minutes for two essay questions.

It’s crucial to manage your time effectively during these exams, especially for longer modules. Our Aviation Insider revision notes and question banks are designed to help you focus on key facts, figures, and concepts, making exam preparation more efficient.

Basic Experience Requirements for Part 66 Licensing Depending on your category, you’ll need a combination of practical maintenance experience and formal training. Here’s a breakdown: Category A, B1.2, B1.4, B3 require 1 to 3 years of practical maintenance experience, depending on prior training. Category B1.1, B1.3, B2 require 2 to 5 years of practical maintenance experience, with options for reduced time if you’ve completed approved training. Category C requires previous certification in B1 or B2 with additional years of maintenance experience, or a relevant academic degree plus industry experience.
