Plain English Summary

3/10 complexity

This Airworthiness Directive requires all Short SD3-30 aeroplanes to have the electrical wiring harnesses and the hydraulic pipelines serving the 7P panel inspected and, if needed, re-routed or fitted with additional clips/sleeving, following Bombardier Service Bulletin SD330-24-29. If adequate clearance cannot be achieved, the hydraulic pipeline must be replaced before further flight. CASA states the measure aims to reduce fouling/chafing and the risk of in-flight fire; operators must schedule and pay for the mandated maintenance.

AD/SD3-30/42 Electrical Wiring and Hydra

AD/SD3-30/42 Electrical Wiring and Hydraulic Pipelines 7/2001

Applicability: All SD3-30 aeroplanes.

Requirement: 1. Inspect electrical wiring harnesses and the hydraulic pipelines servicing the 7P panel for fouling and, if necessary, re-route the wiring harnesses, install additionally supporting clips and sleeving in accordance with Bombardier Aerospace, Short Brothers PLC Service Bulletin (SB) SD330-24-29 dated 30 April 2001.

If adequate clearance between the harnesses and the main pressure hydraulic pipeline cannot be achieved during the Requirement 1 re-routing of the electrical wiring harnesses, replace the pipeline with new rerouted pipeline in accordance with SB SD330-24-29.

Note: This Service Bulletin has been classified as mandatory by the CAA(UK).

Compliance: For Requirement 1 - At the next ‘B’ Check, but no later than 90 days after the effective date of this Directive.

For Requirement 2 - Before further flight, after completion of Requirement 1 This Airworthiness Directive becomes effective on 12 July 2001.

Background: This Directive is intended to ensure that adequate clearance exists between electrical wiring and pipelines containing combustible fluids. These measures are designed to reduce the likelihood of fouling and/or chaffing, with the resultant risk of an in-flight fire.
