(2) Where Transport Canada AD CF-2023-40 refers to "hours air time," this AD requires using flight hours. (3) Where the service information referenced in Transport Canada AD CF-2023-40 specifies to "Do Goodrich Interiors Service Bulletin 1430-25-003," this AD requires replacing that text with "Do Goodrich Interiors Service Bulletin 1430-25-003, Revision C, dated November 22, 2022."
