In some cases this caused control jamming. Since this bulletin was first released these incidents have continued to occur, though at a lower rate. In some cases these incidents have caused loss of control of the aircraft, resulting in significant damage. On 24 November 2010, JSB 019-2 was issued to include new requirements intended to prevent further occurrence of this type of problem.The Service Bulletin referenced in this Airworthiness Directive requires an inspection of the control surface clearances. |\n\n![](image.001.png)\n\nMike Higgins  \nDelegate of the Civil Aviation Safety Authority\n\n29 November 2010","sortOrder":0},{"sectionNumber":"AD/JABIRU/1","sectionType":"part","heading":"AD/JABIRU/1","content":"## AD/JABIRU/1","sortOrder":1},{"sectionNumber":"Primary Flight Control Surfaces","sectionType":"part","heading":"Primary Flight Control Surfaces","content":"## Primary Flight Control Surfaces","sortOrder":2},{"sectionNumber":"24/2010","sectionType":"part","heading":"24/2010","content":"## 24/2010","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
