Slight thread drift, but in the Schweizer 300C PoH it gives a procedure for the pilot to remove and install dual controls (7-18 - Aircraft Handling, Servicing and Maintenance)
Depending on the model the procedure goes so far as to remove the anti-torque pedals and place blanks over the holes (this is for CO2 purposes).
In this case then, is it (legally) acceptable for a pilot to do this on his/her own, as it is a prescribed procedure in the POH?
