DM

            Applicability: BAe 125 Series 800A, Series 800B, Series 1000A, Series 1000B, Hawker 800 and Hawker 1000 aircraft.

            Requirement: Action in accordance with Aerospace Systems and Technologies Ltd Mandatory Service Bulletin S.B.30-25 dated 27 January 1995 (Hawker Raytheon Corporate Jets Service Bulletin SB.30-61-7676A dated 15 February 1995 also refers).

            Note: Aerospace Systems and Technologies Service Ltd Bulletin S.B.30-25 has been classified as Mandatory by the CAA (UK).

            Compliance: Prior to 30 June 1995 for installed pumps or prior to being fitted to an aircraft for spare pumps.

            Background: Aerospace Systems and Technologies has advised that ignition may occur when bare or defectively insulated silver plated wire carrying direct current is exposed to glycol. To avoid this risk, this Directive requires that wire with silver plated conductors is removed from the flying leads of the ice protection system metering pumps. The CAA (UK) compliance date is extended by one calendar month for Australian registered aircraft.
