- Abstract:
- Every Type approved Line Replaceable Unit (LRU) of a Combat Aircraft undergoes a stringent Quality Assurance plan during production, assembly and acceptance testing (ATP) for obtaining airworthiness certification. The traceability of the materials used for the aircraft components and International Standards imposed for testing are well documented for every aircraft system. Strict geometrical tolerances are imposed during manufacturing processes and the inspection cleared components are assembled with an approved assembly procedure documents. Then the assembled units are subjected to an Acceptance Test Procedure (ATP) comprising of several tests to confirm its functional performance. Depending on the performance of the system with respect to the acceptable limits on parameters, the airworthiness certification is awarded for aircraft fitment. In the present paper, a comprehensive QA procedure adopted for obtaining airworthiness certification for a high-speed accessory gearbox is presented. The paper dwells in detail the basic specification and functions of the gearbox, quality control activities for some critical components such as gears and casings, assembly practices and Acceptance testing carried out on the gearbox.
