A defective servo-control may not stop the rotation of the distributor sleeve which could cause untimely movements of the servo-controls which are used on the main and anti-torque rotors. This can lead to loss of control of the helicopter. |\n| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |\n\n![](image.001.png)  \nDavid Punshon  \nDelegate of the Civil Aviation Safety Authority\n\n26 April 2007","sortOrder":0},{"sectionNumber":"AD/S-PUMA/70","sectionType":"part","heading":"AD/S-PUMA/70","content":"## AD/S-PUMA/70","sortOrder":1},{"sectionNumber":"Main and Tail Rotors - Servo Controls","sectionType":"part","heading":"Main and Tail Rotors - Servo Controls","content":"## Main and Tail Rotors - Servo Controls","sortOrder":2},{"sectionNumber":"6/2007","sectionType":"part","heading":"6/2007","content":"## 6/2007","sortOrder":3}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"This is a standard, targeted airworthiness directive addressing a specific manufacturing defect in a specific component.
