The Basics Of Avionics Protection Plans: HAPP/CASP

November 2022

Customers frequently ask about avionics protection coverage for their aircraft. Two of the most notable programs are Collins Avionics Service Program (CASPSM) offered by Collins Aerospace, and Honeywell's Maintenance Service Plan (MSP).  

Both programs offer similar benefits:   

  • Unlimited exchanges, rentals, and repairs
  • Exchange parts shipped overnight delivery
  • No buy-in or initiation fees 
  • Tiered pricing to accommodate budgets

One of the most significant advantages to these programs is knowing avionics costs upfront for the coming year. Having avionics protection coverage is a more cost-effective approach to maintenance. Because, in many cases, failures end up costing more for the exchanged part than the cost of an entire year of coverage. Examples of savings for each program include: 


  • Exchange list price for an AFD-5220E is $45,420
  • Full year of CASP coverage = $42,750 (pricing for a Challenger 350 platform) 


  • Exchange list price for a DU-1080 replacement = $66,200  
  • Full year of HAPP coverage = $75,300 (pricing for Cessna Citation 680 Sovereign platform)

Make sure to lock in prices before the end of 2022. Please reach out to learn more about CASP or MSP.
