Note that 43-13.9-1g reflects that submission is to OK City for filing in the aircraft file. The requirement to send to FSDO for approval is gone. No FSDO employee wants to approve anything that could affect his or her retirement. That does not relievethe person signing and submitting the 337 from conforming to the regulations but does get rid of 90 different opinions about conformity. Having an experienced IA is a big help in wading through this muck.
