This a training program set up by EFC which includes provisions for recurrent training and is set up to continually update a composite repair personnel on new technology, materials and other changes regarding composite maintenance and repair. Records of this recurrent training are sent to your organization and per the individual composite repair technician. On the first course day, each participant receives a multiple choice level test (proficiency check ) about all theoretical and practical topics as stated in the SEA-Int. AIR 4938. Gambling on answers in this level test is not allowed. Not knowing the answer means skipping the question to get a good view of his/her current knowledge level.
Having this done, we can determine the current level of knowledge per individual student to address this during theoretical sessions which save time for the Hands-on practical This course content is derived from and in accordance with the following documents:
As described in the SAE INTERNATIONAL-ARP 6262 document: Recurrent Training: A training program should include provisions for recurrent training to continually update persons on technology, materials and other changes regarding composite maintenance and repair.

Course content theory
At the first-course day, we have determined the current level of knowledge each individual student by the outcome of the level test (Proficiency -check or Prof.-check) of
The instructor uses this in-depth current information to address the necessary course content topics needed to be discussed including the new materials, methods during the theoretical sessions. This saves valuable time for the practical hands-on sessions to come!

perform vacuum leak checks on every repair, keep a record of it
make use of different types of heating equipment
apply the ‘Felt part support technique’ for repair
prepare surface and repair steps and determination of working order steps
prepare a support doubler/caul plate (Tool) on a damaged part
perform a post-repair inspection on all repair and keep a record
program & monitor Hot bonding equipment, change programs and parameters during a high temp. cures.
Take the necessary steps to secure and store all necessary paperwork and witness samples for record keeping of the specific part
At the end of the course, there will be an examination of the current topics discussed and practised during practical
Successful completion is 75% correct answers
The examination will be closed book and can be conducted by a Part 147 approved Examiner upon request
The practical mark will be the average of all marks gained from the practical exercises
All grades will be recorded in the participant individual training records and kept on record at EFC for unlimited time (compliant with Reference EASA Commission Regulation (EU) No 1321/2014)
