requirements, was taken as the basis for the certification
of OUEDP. 8 different panels were constituted under

certification authority under the scope of the agreement,
and approximately 100 workshops and meetings were
organized under which the methods and documents to
demonstrate the certifications proofs were determined.
The project is now subject to establishment of the
certification proofs and approval by the competent
authority. Obtainment of airworthiness certificate by an
engine is not only conditional upon satisfaction of the
technical specifications identified in CS-E, and passing
the certification tests successfully. Satisfaction of the
sought design capabilities and organization of the entity
which developed the engine should also be approved by
the competent authorities. This certification process, led
by SSM, is carried out with due regard to the principles
under EASA Part 21. As part of the process referred to as
