(R) Landing Gear Shock Absorption Testing of Civil Aircraft
|Publication Date:||1 July 2020|
The intent of this document is to provide recommended practices for conducting shock absorption testing of civil aircraft landing gear equipped with oleo-pneumatic shock absorbers. The primary focus is for Part 25 aircraft, but differences for Part 23, 27, and 29 aircraft are provided where appropriate.
The purpose of this document is to provide landing gear shock absorber impact test requirements and recommendations for civil aircraft. Guidance on test analytical correlation is also provided. Test data acquisition is defined which allow for the evaluation of the landing gear performance in regards to energy absorption requirements and validation of the analytical model used to determine design landing loads on the aircraft. The requirements and recommendations provided herein are intended to be used in the test specification report provided to the testing facility.
