Damage such as this increases stress concentration and may develop into cracks at some stage in the future. Ensure that all damage is assessed, repaired if necessary and its cause rectified so it does not reoccur. See figure 1 below, which shows the front side inspection locations (aft side not shown). |\n\n| Compliance: | Inspect initially at 10,000 cycles and then at 500 cycle intervals*.*The Beech maintenance manual allows a tolerance of +/- 10% on special inspection intervals. This tolerance may be applied to the interval compliance time in this Airworthiness Directive. |\n| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| | This Amendment becomes effective on 18 January 2012. |\n| Background: | Cracks and other damage have been found in the rear pressure bulkheads in several Australian aircraft. Undetected cracks or other damage may cause loss of pressurisation or, if large enough, catastrophic structural failure of the rear pressure bulkhead.This Amendment is to correct the maintenance manual reference in the requirement section of this AD, to align with the current version of the Beech 200 Maintenance Manual. There is no change to the technical requirement or compliance interval of this AD, except to remove a transitional provision from the compliance, which is no longer applicable.Amendment 5, effective 12 March 2009, allowed the application of a 10% tolerance to the compliance time. The Beech 200 maintenance manual allows this tolerance for all special inspections which are flight cycle and/or hourly limited. There were no changes to the technical requirements.Amendment 4, effective 24 November 2005, removed the reference to the revision date and page number in the requirement document. The revision date was replaced with “latest revision”. This will ensure that the AD is correct when the Maintenance Manual is inevitably revised again. There were no changes to the technical requirements or compliance.The previous amendment, Amendment 3, effective 15 April 2004, removed Requirement 2 which was to inspect for score marks and repair the aft pressure bulkhead if necessary in accordance with Raytheon Aircraft Mandatory Service Bulletin 53-3513 Rev 1. This inspection is now mandated by a separate Airworthiness Directive, following the issuing of FAA AD 2003-13-16.Amendment 2, effective 11 February 2004, clarified the applicability of the AD, to include aircraft that have had post production removal and installation of the insulation material covering the rear pressure bulkhead. The compliance time for requirement 2 was brought forward to reflect the shorter compliance time required by the FAA AD. There was no change to the requirements in this amendment. |\n| | Amendment 1, effective 20 March 2003, added the requirement to inspect and repair the aft pressure bulkhead in accordance with a mandatory service bulletin issued by the manufacturer. It also added a visual inspection of the area around the cabin outflow valve cutouts for damage which has been observed on an Australian registered aircraft, but was not mentioned as an area to be inspected in the manufacturer’s mandatory service bulletin or maintenance manual. |\n\n| | The original issue of this Airworthiness Directive became effective on 7 March 2000. |\n| --- | ------------------------------------------------------------------------------------ |\n\n![Q:\\Signatures\\HIGGINS_M.gif](image.010.png)\n\nMike Higgins \nDelegate of the Civil Aviation Safety Authority\n\n6 January 2012","sortOrder":0},{"sectionNumber":"AD/BEECH 200/67 Amdt 6","sectionType":"part","heading":"AD/BEECH 200/67 Amdt 6","content":"## AD/BEECH 200/67 Amdt 6","sortOrder":1},{"sectionNumber":"Fuselage Rear Pressure Bulkhead","sectionType":"part","heading":"Fuselage Rear Pressure Bulkhead","content":"## Fuselage Rear Pressure Bulkhead","sortOrder":2},{"sectionNumber":"1/2012","sectionType":"part","heading":"1/2012","content":"## 1/2012","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
