The program culminated in removal of the fuselage life limitation and implementation of a fail safe inspection program supplemented by some component life limitations, as detailed in Chapter 4 of the Super King Air Maintenance Manual. This was reflected in Amendment 6 to the AD, effective 13 June 1991. |\n\n| | Amendment 7 became effective on 27 April 1995 and clarified that no Beech 200 or Beech B200 aircraft were subject to a fuselage retirement life, the Maintenance Manual Chapter 4 inspection program was applicable to all serial numbers.Amendment 8 became effective 25 May 1995, and referenced the revision of the requirement document current at that time.Amendment 9, which became effective on 30 November 2000, referenced Revision 19B3 to the Maintenance Manual. All models on the Australian Register were specifically covered by the Maintenance Manual Chapter 4 serial number applicability.Amendment 10, which became effective on 20 February 2003, updated the requirement section to reference the latest revision of the Maintenance Manual. Compliance times are as stated in the reference document.Amendment 11, effective 15 May 2003, updated the requirement section to add serial number applicability to reflect the differences in applicable requirement document, which depends on aircraft serial number. There was no change to compliance times.This amendment removes the reference to the Airworthiness Limitations being in Chapter 4 of the maintenance Manual. They have now been moved to a separate manual titled “Airworthiness Limitations Manual”. There is no change to the technical requirements or compliance. |\n| --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png) \nDavid Villiers \nDelegate of the Civil Aviation Safety Authority\n\n9 August 2005","sortOrder":0},{"sectionNumber":"AD/BEECH 200/21 Amdt 12","sectionType":"part","heading":"AD/BEECH 200/21 Amdt 12","content":"## AD/BEECH 200/21 Amdt 12","sortOrder":1},{"sectionNumber":"Fuselage Fatigue Life Limitation","sectionType":"part","heading":"Fuselage Fatigue Life Limitation","content":"## Fuselage Fatigue Life Limitation","sortOrder":2},{"sectionNumber":"10/2005","sectionType":"part","heading":"10/2005","content":"## 10/2005","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":4,"scope_assessment":{"changed":false,"description":"The amendment does not change the AD's technical scope or compliance obligations; it updates which document contains the airworthiness limitations (moving them out of Maintenance Manual Chapter 4 into a separate Airworthiness Limitations Manual) and clarifies serial‑number applicability.
