Only an air test can do that. There can be bent components, interference, corrosion and other issues that inhibit a properly charged gas strut and prevent nose extension and main gear overcentre lock. I also do not like removing parts for inspection just to inspect them unless there's a good reason or a symptom justifying removal and therefore I do not remove the gas strut on a time basis. The risk of R&Ring perfectly working parts is not trivial in my experience and that is from shop and personal experience. Therefore, I test (ir)regularly in the air using the hydraulics as a backup. I do not remove the strut unless the tests suggest a replacement. I got the last from McMaster Carr. Details in the archives. Paul Legacy On 18 March 2014 07:48, Dominic V.
