Flapper Peening

This course covers the theoretical and practical aspects of Flapper Peening. The participants will learn the fundamental basics of flapper peening and gain practical skills by doing it into practice. In the practical session, the participants will use a FlapSpeed® PRO to gain hands-on experience with the process while generating a saturation curve. A written exam is given to the participants and a passing grade will provide a Certificate of Achievement.


Flap Peening:

Flap Peening is the Shot Peening of small areas of components or parts that are installed on the aircraft. Flap peening can be done best with the specialized tooling made by Shockform Aeronautique: The flapspeed PRO. Aircraft manufacturers demand that the person who performs the flap peening procedures is qualified and trained.

This training makes sure you become qualified for the job!

Not only will you become familiar with how the Flapspeed PRO works, you also get an extensive explanation of the Flap Peening procedure. After following this training you will fully understand the flap peening procedure given by, for example, Airbus and Boeing.
