Revision 03 was issued to add the aircraft model F4-605R and update the effectivity. Revision 04 was issued to add aircraft model C4-605R/F and MSN 0755 and 0758 to the effectivity. Change notice 3A was also incorporated, this introduced the Airworthiness Directive 94-069-158(B). Revision 05 was issued to add the aircraft model F4-622R and update the effectivity. Revision 06 was issued to increase the effectivity to MSN 878. A reference was amended and the opportunity was taken to update the MSN per operator list. Minor changes to the new Service Bulletin format were also added.
