Applicability: Model 717 series aircraft, manufacturers fuselage numbers 5004 through 5036. Requirement: Action in accordance with the technical requirements of FAA AD 2001-17-21 Amdt 39-12412.

Note: Boeing Service Bulletins 717-27A0010, 717-27-0013, and 717-27-0013 Revision 01 refer.

Compliance: As specified in the Requirement document with a revised effective date of 29 November 2001.

This Airworthiness Directive becomes effective on 29 November 2001.

Background: This Directive requires repetitive inspections of the spoiler hold-down actuator rod ends for breakage; and eventual replacement of the rod ends with new rod ends, and re-identification of the spoiler hold-down actuators, which constitutes terminating action for the repetitive inspections. Failure of the rod ends due to fatigue could result in loss of the back-up protection of the spoiler float hold-down and unavailability of monitoring for an uncommanded spoiler movement.
