Electronic Engine Control Unit (EEC/EECU) — P/N 1240KDC03-005
Condition: As Removed, with ATA Spec 106.
Electronic engine control unit for the Bombardier Learjet 60, controlling the Pratt & Whitney Canada PW305A engine. The EEC is the digital controller for the engine — scheduling fuel and managing engine operation across the flight envelope. Catalogued by Bombardier as “Control, Engine Electronic” (the sibling 1240KDC03-002 is the E.E.C.U.).
Configuration & service-history disclosure: This is the legacy Smiths-manufactured EEC configuration (vendor P/N 1240KDC family; associated engine P/N 31B4741). Buyers should be aware that Pratt & Whitney Canada issued Service Information Letter SIL PW300-201, recommending an upgrade to the latest EEC configuration (per P&WC Service Bulletin PW300-72-24434), and that P&WC repair support for these older Smiths-built EEC units is being phased out. Transport Canada also issued a related safety alert (CASA 2021-09) regarding this EEC family. This unit is offered as a legacy-configuration spare / repairable for operators and shops who require this configuration. Purchaser must review the applicable SIL/SB and current airworthiness requirements, and confirm suitability for their engine, before installation.
Supplied with an ATA Spec 106 Part or Material Certification Form documenting traceability and as-removed condition. (ATA 106 is a traceability form, not an FAA Form 8130-3 airworthiness approval.)
