Sorry for being not specific. The issue is actually the deactivation of the airstair of a 737. The airstair works just OK but the company wants not to use it. The technicians just pulled the cb's and labeled them, along with all the switches associated with it, inop having no log entry. And the airstair is not the only one system. We got the in-flight entertainment in the same situation.
I have checked the AMM but I fond no reference to this procedure. I believe this procedure should be in MOE but it is not there. Anyway, I personally think that it should be some kind of entry into the teh log saying the sys is deactivated and specifying which CB's are pulled along with required labeling.
