EASA (European Union Aviation Safety Agency) regulations and training programs for aircraft maintenance are organized into modules and sub-modules. Module 3 of the EASA Part-66 syllabus covers various topics related to aircraft systems, including sub-module 17, which is specifically focused on “Materials and Hardware.”
Here's an overview of EASA Module 3, Sub-Module 17:
Module 3: Materials and Hardware - Module Description: Module 3 deals with the knowledge and skills required by an aircraft maintenance engineer regarding materials, hardware, and the techniques used in aircraft construction and repair. This module is critical because it ensures that engineers have a deep understanding of the materials and hardware used in aircraft and how they impact aircraft airworthiness and safety.
Sub-Module 17: Materials and Hardware - Sub-Module Description: Sub-Module 17 delves into the details of materials and hardware used in aircraft construction and maintenance. It covers various aspects related to materials science, including the types of materials used in aircraft, their properties, and their applications. Additionally, it discusses the importance of proper hardware selection and installation in aircraft maintenance.
Here are some of the specific topics that may be covered in EASA Module 3, Sub-Module 17:
1. Materials used in Aircraft Construction: This section may cover the types of materials commonly used in aircraft manufacturing, including metals (aluminum, titanium, steel), composites, and other materials like plastics and ceramics.
2. Material Properties: Engineers learn about the physical and mechanical properties of materials, such as strength, elasticity, corrosion resistance, and heat resistance. Understanding these properties is crucial for selecting the right materials for different aircraft components.
3. Material Testing and Inspection: This part of the sub-module may cover non-destructive testing (NDT) techniques used to inspect materials and structures without causing damage, as well as destructive testing methods when needed.
4. Hardware and Fasteners: Engineers are taught about the various types of hardware and fasteners used in aircraft assembly and repair, including bolts, nuts, rivets, and screws.
5. Corrosion and Corrosion Prevention: Understanding corrosion and methods for preventing or mitigating it is essential for aircraft maintenance to ensure the structural integrity of the aircraft.
6. Composite Materials: This sub-module may also touch on composite materials, their properties, and their use in aircraft construction, as composites are increasingly common in modern aircraft.
EASA Part-66 training programs, including Module 3, Sub-Module 17, are typically provided by approved Maintenance Training Organizations (MTOs) and are designed to prepare individuals for the EASA Part-66 examinations required to obtain an Aircraft Maintenance License (AML).
As EASA regulations and syllabi can change over time, it's essential to consult the latest documents and guidance from EASA or the relevant aviation authorities for the most up-to-date information regarding Module 3, Sub-Module 17, and other training requirements.
