Plain English Summary

3/10 complexity

This AD requires operators of Boeing 717 aeroplanes (fuselage numbers 5004–5036) to perform repetitive inspections of spoiler hold‑down actuator rod ends for breakage and to replace and re‑identify the rod ends as the terminating action, pursuant to FAA AD 2001‑17‑21 and referenced Boeing service bulletins. CASA issued the directive effective 29 November 2001. Operators pay for inspections, parts and labour; the rule obliges changes to maintenance scheduling and creates an enforceable compliance requirement to reduce risk of actuator fatigue failures.

AD/B717/3 Spoiler Hold-Down Actuator Rod End 12/2001

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.
