When should landing gear retraction checks be accomplished?

Landing gear retraction checks are a critical aspect of ensuring that the landing gear system operates correctly and safely. Performing these checks during annual inspections and after replacing components is essential because it confirms that the entire landing gear system, including any new parts, is functioning as intended.

Annual inspections provide a comprehensive evaluation of the aircraft's systems, allowing for the identification of any issues that may not be apparent during regular operations. Moreover, when components related to the landing gear are replaced, a retraction check is vital to verify that the new components have been installed correctly and integrated seamlessly into the existing system. This practice also helps to catch any potential failures early on and ensures compliance with safety regulations and manufacturer recommendations.

Other scenarios, such as just doing these checks during routine maintenance or after a hard landing, may not be sufficient to guarantee the optimal performance of the landing gear over the aircraft's lifecycle. Therefore, conducting these checks systematically during thorough inspections and after any repairs or replacements is the most effective approach to maintaining safety and reliability in landing gear operation.
