This review determined that it is not appropriate to use STC’s for this purpose because ICA’s as a whole are not part of the type design of a certificated product. As result, the FAA has concluded that the applicability of MORE STC’s should not be expanded to include additional engine models…]", Aerocivil will not accept the inclusion of additional engine models to the STC here accepted and already approved by FAA. Any major change of the STC information must be reported and documented to the Colombian Civil Aviation Authority (AEROCIVIL).
