Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of Short SD3‑60 aeroplanes (serial numbers SH301–SH3642) to inspect left/right outer wing‑to‑strut and stub‑wing‑to‑strut attachment fittings in accordance with Shorts Service Bulletin SD360‑57‑12. Initial inspection must occur before 9,600 flight hours or by 29 November 1990 (whichever is later), then every 600 flight hours.

Operators or their maintenance providers must carry out and pay for the inspections and related downtime; embodying modification SD360‑57‑03 ends the repetitive inspections. The AD follows a damage‑tolerance evaluation that found fatigue‑crack risk to wing integrity.

AD/SD3-60/30 Stub Wing and Outer Wing Strut Attachment Fittings

Applicability: All models serial number SH301 to SH3642 inclusive.

11/90

Requirement: Inspect the left and right outer wing to strut attachment fittings and left and right stub wing to strut attachment fittings, as applicable by serial number, in accordance with Shorts SD3-60 Service Bulletin SD360-57-12.

Note 1: UK CAA has classified this action as mandatory.

Note 2: Embodiment of Service Bulletin SD360-57-03 will constitute terminating action for the purposes of this AD.

Compliance: Prior to the accumulation of 9600 flight hours or prior to 29 November 1990 whichever is the later, and thereafter at intervals not to exceed 600 hours component time in service.

Background: Damage tolerance evaluation of the SD3-30 type fittings installed on the affected aircraft has indicated that the maximum safe inspection interval is 600 hours.

Undetected fatigue cracks in these fittings could result in loss of structural integrity of the wing. The manufacturer is currently developing a modification that will preclude the need for repetitive inspections.
