Basic Facts about Quick Engine Change Kit

Business & Careers
by joshuagreen on

The Quick Engine Change (QEC) kit is a collection of components and accessories that are being installed into a bare engine. It offers a number of great advantages for various procedures regarding the technical preparation of an aircraft.

With the use of QEC, the required time for the installation of the whole power plant into an aircraft will be minimized. QEC kit mainly includes generators, thrust reverser, pumps, wiring harness, fluid lines and nose cowl which are useful to make the installation of the power plant easier and more accurate.

The three main types of a QEC kit are basic, neutral and full. A basic QEC kit includes at least all major parts and accessories that are useful in having an engine test. With a neutral QEC kit, the components of a basic kit are included plus additional parts which can be used for the installation on an airframe though it is not an airframe specific. On the other hand, a full QEC kit is a type of neutral kit which includes all the specific items for the airframe.

The actual type of a QEC kit depends on the type of aircraft where the engine should be installed. The position of the engine on the aircraft also determines what type of QEC should be used. The aerospace standard 9120 or AS9120 refers to the combination of a QEC kit and the power plant as a QEC unit.

Aircraft technicians that take charge of the installation and configuration of a QEC unit are first required to have AS9120 certification. This certification states that the aircraft technician fully understands all the necessary information regarding the QEC unit as well as the procedures in its installation, monitoring and maintenance.

Moreover, AS9120 is a part of the International Organization Standard (ISO) and it also includes ISO 9001 standard for quality management system. It is used by organizations that are responsible for the procurement of aircraft parts, assemblies and materials. These organizations are also in charge of distribution of products to customers of the aerospace industry. However, they are not responsible for any rework or repair of the aerospace products.
