Part 66 (2023-989) Compliant

Revision 5 of Sept 2025 rewrites portions of submod 5.4 (rivets) and submod 11 (electrical connectors).

As with all ATB EASA modules, Module 6 B1: Materials and Hardware strictly matches the requirements of Part 66 including its content, sequence, and the required learning levels (L1, 2, or 3) needed for an approved B1 mechanic maintenance technician program, and is so approved by many national authorities as a part of the training programs of Part 147 schools within their jurisdiction.

As prescribed in Part 66 Appendix 1, the topics are divided in 16 sections:

• Aircraft Materials - Ferrous (L1/2)
• Aircraft Materials - Non-Ferrous (L1/2)
• Aircraft Materials - Composites (L2)
• Aircraft Materials - Wood (L2)
• Aircraft Materials - Fabric (L2)
• Corrosion (L1/3)
• Fasteners - Screw Threads (L2)
• Fasteners - Bolts, Studs, Screws (L2)
• Fasteners - Locking Devices (L2)
• Fasteners - Rivets (L2)
• Pipes and Unions (L2)
• Springs (L2)
• Bearings (L2)
• Transmissions (L2)
• Control Cables (L2)
• Electrical Cables and Connectors (L2)

Complete table of contents is included with the Look Inside link above.

Note that the required learning levels for this B1 mechanical edition differ from the B2 avionics edition with this B1 edition being the more advanced.

Each topic is explained with understandable text and exceptional full color illustrations in step-by-step detail. You will learn by understanding concepts and how and why each skill is useful in the day-to-day tasks of the aircraft technician in the aviation maintenance environment. For FAA A&P students, all required topics are covered, however to the somewhat higher level of proficiency as the EASA licenses require.

Instructor Services:
For schools considering the adoption of ATB modules as your primary student notes, we offer various additional services including projectable image banks, examination question databases, and generous additional support for instructors and your requirements for competent authorities.
