Boeing 737NG Control Wheel tolerances
 

Hi Guys!
Im working as a Simulator technician, and a former Aircraft Engineer.
Since my new company isnt within a Airline we are not able to accsess the AMM, and that can from time to time be a bit challenging.
So, on our Boeing 737NG simulator it have been snagged that the control wheel/collums have several centimeters of play in all directions. And yes, thats true. But before we start overhauling the entire flight control system on this badass i want to check what the AMM says regarding tolerances of play on the collum and wheel.

Are any of you able to help me out, by checking this in the AMM? Im pretty sure the manual describes the test by using a inclinometer, and checking deflection etc...
Im greatfull for any help/information :)

I'll check and see when I get back to a work computer. I would think if you haven't done it already, to try and get it into a neutral slack rigging if you can. Just from my "hangar pilot" experience, there doesn't seem to be much of any slack in the feel of the yoke.

Not sure you should be referring to an AMM in this case, surely there's a simulator manual available? Given the length of control run on a sim is small by comparison to the real thing then I suspect you have something seriously amiss, if you have several cm of play.

First of all, we use the AMM because we can compare it towards the limitations on the real aircraft. The sim is from 1998, so yes, the load units/cables etc are worn, but as long as they are within limits its no point in overhauling the system wich takes serius amount of downtime. The Simulator Manual really doesnt give us any good indication. This is a subjective snag from a pilot, and our quality test guide will provide us with a automatic test that is testing the control collum deflection of the simulated ailerons/spoilers. But again, this is a subjective snag, so to close it with a decent explenation, refering to the AMM would have been great.

From my check flying days I seem to remember a total of 1.5 inches free play was allowed.

I'll try and find the official document.
