| Applicability: | All Model 767-200, -300, -300F, and 400ER series aircraft. |
|---|---|
| Requirement: | Action in accordance with the technical requirements of FAA AD 2007-24-08Amdt 39-15274.Note: Boeing Special Attention Service Bulletins 767-27-0197 Revision 1 or767-27-0198 Revision 1, or later FAA approved revisions, refer. |
| Compliance: | As specified in the Requirement document, with a revised effective date of14 February 2008. |
| This Amendment becomes effective on 1 February 2008. | |
| Background: | The FAA received reports of freeplay-induced vibration of the rudder and the elevator. The potential for vibration of the control surface must be avoided because the point of transition from vibration to divergent flutter is unknown. The actions required by this Directive are intended to prevent excessive vibration of the airframe during flight, which could result in loss of control of the aircraft.Amendment 1 is issued in response to a new FAA AD, which requires revised repetitive measurements of the rudder and elevator freeplay, corrective and related investigative actions if necessary, and repetitive lubrications of the rudder and elevator components. |
