 I. The Flight-Controls Surface-Alignment Record
 S 225-023
 (1)  Figure 503 contains the Flight-Control Surface-Alignment data. Use this data to make sure that the control surface alignment is correct. Do an alignment check after an overhaul, rigging, or a control-surface replacement-procedure has been done. Keep an alignment record for each airplane since this will help to locate problems before they become bad.
