This change transmits revised pages to Order 8110.4C, Type Certification. This change is issued to remove procedures and forms related to the notification process used when initiating type certification projects, for the determination of directorate involvement, and for aircraft certification office (ACO) to ACO coordination. The revised certification project notification (CPN), directorate involvement determination, and ACO to ACO coordination procedures are now published in Order 8110.115, Certification Project Initiation and Certification Project Notification. This change also introduces a requirement for ACOs to submit updated Type Certificate Data Sheets (TCDSs) for posting on the RGL website no later than 30 calendar days after TC transfer to a new TC holder. And finally this change also includes a corrected title for figures 1 and 7 of appendix 2.
