Abstract
Airworthiness standards of Korea recommend verifying structural safety by experimental tests and analytical methods, owing to the development of analysis technology. In this study, we propose a methodology to verify the structural safety of aircraft components based on airworthiness requirements using an analytical method. The structural safety and fatigue integrity of a linear actuator for flap control of aircraft was evaluated through numerical analysis. The static and fatigue analyses for the given loads obtained from the multibody dynamics analysis were performed using the finite element method. Subsequently, the margin of safety and vulnerable area were acquired and the feasibility of the structural safety evaluation using the analytical method was confirmed. The proposed numerical analysis method in this study can be adopted as an analytical verification methodology for the airworthiness standards of civilian aircraft in Korea.

Airworthiness standards of Korea recommend verifying structural safety by experimental tests and analytical methods, owing to the development of analysis technology
Many studies have been conducted on certification for aircraft design and manufacturing to reduce the cost and time required for development and secure structural safety by introducing analytical methods
As a result of recent advances in analysis technology, regulations that require structural safety to be verified through a combination of analysis and tests have been consistently prepared in the Korean airworthiness standards (KAS) (KAS Part 23.305 and Korean Airworthiness Standards (KAS) Part 23.307)
Summary
Airworthiness standards of Korea recommend verifying structural safety by experimental tests and analytical methods, owing to the development of analysis technology. We propose a methodology to verify the structural safety of aircraft components based on airworthiness requirements using an analytical method. The structural safety and fatigue integrity of a linear actuator for flap control of aircraft was evaluated through numerical analysis. The proposed numerical analysis method in this study can be adopted as an analytical verification methodology for the airworthiness standards of civilian aircraft in Korea. Numerical Evaluation of Structural Safety of Linear Actuator for Flap Control of Aircraft Based on Airworthiness Standard. The Korean Airworthiness Standards (KAS) announced by the Ministry of Land, Infrastructure and Transport of South Korea (MOLIT) specifies that the flap should be securely fixed when it is at the required position in the flap-control system (KAS Part 23.697) and it should be designed not to cause a failure that may lead to unstable flight characteristics (KAS Part 23.701) [4].
