DC Power Centre (DCRC) shipping container

Effectivity: Challenger 300/350 aircraft

ATA 24

The recent release of the Service Bulletins 100-24-29 and 350-24-04 (SPECIAL CHECK/REWORK – DC POWER CENTER (DCPC) SYSTEM – REPLACEMENT OF THE LEFT DC POWER CENTER) will cause an increase of DCPC units removed in service and therefore, an intensification in shipment.

Bombardier would like to remind operators about the importance to reuse the standard shipping container (Figures 1 & 2) the spare unit came in when returning the core DCPC to Bombardier.

Typical damages reported by the vendor to units not returned in the standard container are DCPC bent chassis, distorted mounting tabs, distorted cover and circuit breaker panel window cracked/broken. As an example, a bent DCPC chassis will necessitate the removal/reinstallation of all its internal components for repair, thus greatly increasing the repair costs of that unit. The use of the standard container will ensure the unit is not damaged during its return to the vendor repair facilities.

Bombardier would also like to remind operators to include the DCPC terminal blocks related hardware such as TB covers (Figure 3), washers, lock-washers and nuts (Figure 4) with the unit returned. Any repair associated to bad packaging or missing components/hardware will be automatically charged back to the sender.
