This Airworthiness Directive requires operators of all BAe 146 (100/200/300) and Avro 146‑RJ (70/85/100) aeroplanes to install ceramic terminal blocks by incorporating Modification HCM01693A per BAe Systems Mandatory Modification Service Bulletin SB.71‑077‑01693A Revision 2. CASA sets a compliance deadline (before 31 July 2004) to address fireproofing concerns; the amendment revises compliance timing, updates part numbers and installation notes, and replaces a prior amendment.

Amdt 2

Ceramic Terminal Blocks 8/2002

Applicability: All BAe 146 100, 200 and 300 series aeroplanes.

All Avro 146-RJ70, RJ85 and RJ100 series aeroplanes.

Requirement: Incorporate Modification HCM01693A in accordance with BAe Systems Mandatory Modification Service Bulletin SB.71-077-01693A Revision 2 dated 28 May 2002.

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

Compliance: Before 31 July 2004.

This Amendment becomes effective on 8 August 2002.

Background: BAe initially advised that an investigation into the use of ‘Low Temp’ terminal blocks ‘G’ in engine zones 412, 422, 432 and 442 identified the requirement to replace existing terminal blocks with a ceramic terminal block that meets the fireproof requirements of these zones.

The original issue of this Directive required replacement of the existing terminal blocks with ceramic terminal blocks.

Amendment 1 was issued following advice from BAe that the original ceramic terminal block mounting screws (Part Number AV0022B24) were too short

This Amendment follows the issue of Revision 2 of the service bulletin which revises the compliance time, introduces changed part numbers and additional installation notes.

The original issue of this Airworthiness Directive became effective on 27 December 2001.
