for airplane repairs, alterations, or 
modifications that may affect air-
worthiness. 

(4) Holders of type certificates and 

their licensees producing new air-
planes.

sign change is not required to comply 
with any applicable airworthiness re-
quirement of this part if the applicant 
elects or is required to comply with a 
corresponding amendment to part 25 of 
this chapter that is adopted concur-
rently or after that airworthiness re-
quirement.
