Management & Governance

Maintenance quality is a critical foundation for flight safety. Maintenance management focuses on performing aircraft inspections and maintenance tasks to ensure the reliability of aircraft systems. EVA Air adheres to the General Maintenance Manual (GMM) manufacturer technical specifications, and regulatory requirements in aircraft maintenance and operational monitoring. Each maintenance detail is diligently completed in accordance with these guidelines. Therefore, the cultivation of maintenance culture and disciplined implementation are the foundation of maintenance. Moreover, the spirit of “Safety First and Quality is everything” is also our primary criterion for aircraft maintenance.

In order to ensure the quality of maintenance, the Precision Measurement Equipment used in aircraft maintenance operations is based on the manufacture technical specifications of the equipment. Equipment is regularly sent for factory inspection and checked against national calibration standards such as the US National Institute of Standards and Technology (NIST) or equivalent to ensure compliance with the specifications of the manufacturer.

Regardless of maintenance operations on the apron or in the hangar, relevant specific operation items require re-checking through the quality control inspection process or through flight verification to confirm the safety of the aircraft. These repeated inspections and protective layers of rigorous maintenance operations reflect and ensure the standards of continuous airworthiness.

Our safety guarantee is in truly grasping every detail of maintenance. From the safe use period of each component to the precise requirements of all maintenance procedures, the purpose is to reduce all possible risks and fulfill the requirements of flight safety. EVA Air not only insists on maintenance quality, but also sets dispatch rate target for each fleet. Dispatch rates and the reasons for aircraft delays are monitored and analyzed during monthly Quality Review Board. Aircraft maintenance plans are adjusted or engineering commands are executed to prevent delays and maintain the fleet dispatch target to provide safe and punctual flights.

To ensure aircraft reliability and flight safety, technical information and problems generated during daily operations are collected and analyzed according to the Reliability Control Program to formulate maintenance methods for providing various warning standards for aircraft abnormalities. In the event that aircraft abnormality rate exceeds the standard, engineers from various professional domains are assigned to analyze and formulate improvement projects. The projects are incorporated into the aircraft maintenance plan in order to maintain the reliability of the aircraft system, improve maintenance quality and ensure flight safety.
The technical information and problem characteristics generated during the daily operation of the aircraft are divided by the Reliability Control Program into (1) System, (2) Components, (3) Powerplant, and (4) Structure for monitoring. The “Reliability Meeting” and the “Quality Review Board” convene regularly each month to monitor, discuss and formulate improvement for issues such as aircraft maintenance reliability, technical corrective and preventive measures, and human errors.

To promote sustainable innovation, in managing the return of leased aircraft, our aircraft maintenance team came up with operation improvement proposals that addressed environmental, social, and corporate governance concerns. These proposals aim not only to enhance aircraft performance reliability and operational safety, but also to effectively reduce energy consumption. Furthermore, to improve the quality and efficiency of system services, we plan to integrate the existing e-check and i-fuel systems, incorporating both software and hardware components. The goal of this integration is to effectively improve user productivity and strengthen the Company’s overall competitiveness. The system integration project is scheduled to launch in January 2024.

Flight Control Department works around the clock for flight dispatch and control. The Flight Information System (FIS) and Flight Trace System provide access to flight-related status, and tracks changes in the external environment (e.g. airport and weather). For flight dispatch operation, the personnel responsible for drawing up flight plans are all qualified dispatchers with licenses issued by the CAA. With their expertise and assistance of the system, a safe, fuel-saving and comfortable journey is made possible on every EVA Air flight.
EVA Air participates in European Free Route Airspace Work Group, FAA Cross Polar Work Group (CPWG) and Informal Pacific ATC Coordinating Group (IPACG) to improve the European, North America, Russian Far East, North Pacific and Japan region Air Traffic Service (ATS) efficiency of transit flights. In addition, it discuss and develop a fuel-saving and time-saving route to reduce the impact of greenhouse gas and air pollutant emissions on the environment.
