Civil Aircraft Maintenance Companies Repair The Failure Analysis And Quality Improvement Methods

With the national economy and the continued growth, China's aviation shipping industry has achieved remarkable achievements. While air service amounts increase sharply, flight delay as a problem has become increasingly prominent. The problem has created tremendous loss for the passenger and airlines. Except the objective reasons such as weather, air traffic control, airlines' reason is accounted for a considerable proportion. Most of these delays are due to the aircraft maintenance: the abnormal aircraft can not get repair in time.Based on modem quality management ideas and methods for the theoretical background, this paper analyses the maintenance failures in the civil aircraft maintenance enterprises, and advance the corresponding quality improvement methods. First, based on Analysis of maintenance enterprises in quality management status and the long-term accumulation of delays record data, Discussion on the route maintenance caused flight delays reasons. According to human, machine, material, method, measurement, and environmental quality management principles, Search maintenance failure caused the five reasons by use of the Pareto analysis. Secondly, the use of control charts to judge whether the repair process at the state controlled, and to monitor the quality state. Then, study the inspection techniques. Finally, discuss the quality improvement methods.This paper characteristic and the innovation place mainly display in:Research aircraft maintenance enterprises take data analysis as foundation process improvement method.Using Pareto analysis and the causes and effects chart analysis, determines the main reason of the maintenance failures.Through the maintenance failures factor statistical analysis, using control chart to monitor the maintenance.
