\n```\n\n| Background: | It has been determined that some bearings may not have been staked as required. Consequently, the functionality of affected parts may be limited. This situation, if not corrected, could lead to loss of control of the helicopter.BHTC Operational Safety Notice OSN GEN-09-38 dated 7 April 2009 provides further information on this subject. |\n| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png) \nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n12 August 2009","sortOrder":0},{"sectionNumber":"AD/BELL 222/45","sectionType":"part","heading":"AD/BELL 222/45","content":"## AD/BELL 222/45","sortOrder":1},{"sectionNumber":"Flight Control Bearings","sectionType":"part","heading":"Flight Control Bearings","content":"## Flight Control Bearings","sortOrder":2},{"sectionNumber":"10/2009 TX","sectionType":"part","heading":"10/2009 TX","content":"## 10/2009 TX","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
