Aircraft braking system MTTR (mean time to repair) authentication method

Abstract

The present invention provides an aircraft braking system MTTR (mean time to repair) authentication method. The method comprises: by performing authentication on calculation data of the MTTR, determining an accuracy degree of the calculation data; if the calculation data is accurate, incorporating the MTTR into an aircraft maintenance manual; and performing experimental authentication on the MTTR that is obtained by calculation authentication on an aircraft, and if the calculation authentication is not coincided with the experimental authentication, performing modification according to data of the experimental authentication. The MTTR, which is authenticated by the aircraft braking system MTTR authentication method provided by the present invention, is coincided with MTTR that actually occurs in use, the MTTR of each product that passes the calculation authentication is incorporated into a civil aircraft maintenance manual, repair of a braking system product is arranged according to the MTTR that is regulated in the maintenance manual during civil aircraft flight dispatch, and the accurate MTTR avoids economic loss and time loss that are brought by delay of civil aviation flights.

Description

technical field [0001] The invention relates to the field of maintainability of aircraft braking systems, in particular to a method for verifying the average repair time of aircraft braking systems. Background technique [0002] Civil aviation aircraft not only require airworthiness, but also have strict restrictions on flight delays. When the average repair time is not allocated properly, there will be situations where maintenance work cannot be completed within the specified time, causing flight delays. [0003] GJB451A's definition of mean repair time is: "A basic parameter of product maintainability, which is a design parameter. Its measurement method is: under specified conditions and within a specified time, the product is at the specified maintenance level, The ratio of the total time of corrective maintenance to the total number of faults of the repaired products at this level.” There are three levels of maintenance for aircraft products: outfield level, intermediate...

Problems solved by technology

[0017] Disadvantages of the calculation and allocation method of maintainability index above: In the summarized model (1), the average repair time of the product is inversely proportional to the failure rate; and it is related to the number of components, the more the number of components, the higher the failure rate

It does not reflect the installation position of the product on the aircraft and the factors affecting the accessibility of the product on the aircraft. It also has the disadvantage of short distribution time for difficult-to-maintain products and long distribution time for easy-to-maintain products.

[0018] To sum up, the existing average repair time calculation method does not consider the factors affecting on-site maintenance, and does not mention the verification of the average repair time. It is directly applied, and there are flight delays when the repair time exceeds the specified time.
