The aircraft, which is supplied by the original equipment manufacturer (OEM), will have a prescribed configuration. The maintenance procedures to be followed for attaining an acceptable level of reliability and operating output, is also prescribed by the equipment supplier. The regulatory authority approves the configuration of the aircraft and its major assemblies, together with the maintenance program to be adopted, before the aircraft is inducted for regular operations.
During its operating life, in order to increase reliability and ensure maximum availability, aircraft and components are subjected to innumerable changes. A modification to an approved aircraft or component configuration or their maintenance procedures, is referred to as “Engineering Changes”. The engineering changes are typically triggered from the OEMs in the form of “Service Bulletins”, or local aviation authorities in the form of “Airworthiness Directives”, or internally generated during reliability analysis. The change communications are processed and executed through suitable engineering documents.
Engineering document is a document, which contains the information regarding the various engineering changes that have to be carried out on the maintenance object (aircraft or component). Typically an engineering change involves modification of the component part numbers, or change in the maintenance programs. Engineering document identifies the complete details of engineering changes that are to be carried out including the material and resource requirements. If the change request is triggered from external sources (OEM), the material required to accomplish the change will be identified in the form of a “kit”. The kit comprises multiple parts (piece parts) in the required quantity, to execute the change in one piece of the effective operating asset (aircraft or component). The kit will be supplied by the OEM or the vendor identified by the OEM, and needs to be procured for executing the engineering document.
Each Engineering Document is uniquely identified through a number that is either system generated or manually assigned. The background information and referential information such as the ATA chapter, access panels, zone references can be provided. Material and resource requirements can also be identified in the Engineering document. Multiple tasks can be identified and schedules defined for each task. Based on their applicability, Engineering documents are classified as “Aircraft”, “Engine” or “Component”. While the effectivity for Aircraft related Engineering documents will be specified in terms of aircraft models and specific aircraft registration numbers, the effectivity for component related Engineering Documents will be in terms of part numbers and serial numbers. Configuration change information also forms an attribute of an engineering document.
