The CASP Elite program offers a 10% discount on upgrades to existing equipment requiring factory service bulletins. For example, Service Bulletin (SB) 514 converts the -409/410 TDR-94D Transponder to -501 ADS-B DO260B status for $4,650. An aircraft covered under CASP Elite would receive an additional 10% off, or $465.
Additionally, CASP Elite offers a $5,000 discount on the purchase of new Collins equipment. An example would be the addition of a WAAS/GPS GPS-4000S sensor into an aircraft requiring it for an ADS-B upgrade at a cost of $32,600, and an aircraft covered under CASP Elite would receive an additional $5,000 discount.
