Composite Tooling Fabrication (Stage I)

Course code: TECH-171 (Stage I)
Course duration: 5 Days


This is our Quick Repair support tooling fabrication course (Stage I) which is developed for personnel of technical departments, MRO stations or AOG service stations
who want learn to fabricate Quick support tooling for aircraft composite and metal bonded parts to stabilize while being repaired at elevated temperatures

Advised pre-requisites

Our EFC Courses, TECH-001, TECH-010 or TECH-020 (Stage I to 3 ) can be a prerequisite, or 2-3  year repair experience on aircraft composite parts is required for this course, or an equivalent level. If in doubt, contact us to assess your equivalent level of knowledge and skills needed for this course.


Personnel of technical departments, MRO stations, AOG services such as Composite Repair technicians, certifying staff, engineers and others.
