Engine+ Upgrade
Piper Cheyenne Series I, II, IIXL


1P&WC Enhanced New-Engine Warranty 2,500 hours/5 years with prorated coverage to the 3,600 hour TBO

The Blackhawk XP135A Engine+ Upgrade gives you the extra horsepower you need to achieve higher rates of climb, faster cruise speeds, and shorter times to destination. The upgrade exchanges the original engines for factory-new Pratt & Whitney Canada PT6A-135A engines, complete with new engine warranty and reliability without any airframe modification.

All this performance and value starts with an initial investment, minus the cost of your next overhaul. Other financial factors to consider include:

  • Lower operating costs
  • Pratt & Whitney core engine credits up to $35 per hour per engine for every hour remaining to the factory TBO
  • Strongest resale value of any engine upgrade on the market
  • Nearly every Blackhawk-powered aircraft sold within 500 hours of the upgrade recovered close to more or than the combined investment of the airframe and engines
  • Save time on each mission giving you more time to be productive


  • More power for faster climb and cruise speeds
  • Reduced annual cost of operation
  • Significant return on investment
  • Higher resale value

Just over a year ago I sold the Cheyenne in one day to a very happy buyer. Your engines made the deal!! Your engines got me started on going faster 265-70 KTAS and now I’ve moved up to 365 KTAS at FL410. Thanks again!

Jeff Mickler
Cheyenne I

The XP engine upgrade has exceeded my expectations and is by far the best aftermarket investment I have ever made on any aircraft. Having extra horsepower at the right hand makes the Blackhawk Cheyenne an absolute thrill to fly.

Dan Rogers
Cheyenne I

I’m so glad I did the upgrade. I had very high expectations on the performance promised by Blackhawk, and Blackhawk came through with flying colors!

Randy Kerns
Cheyenne II

The engines made an old, tired Cheyenne an incredible machine.

I couldn’t be happier with the 135A’s. I save about 30 to 45 minutes on most of my flights and my fuel cost has stayed the same. It’s just fun to fly.

Michael Miklus
Cheyenne II

It climbs at 2,000 FPM at the same speed I used to cruise at. I have seen barber pole speeds on every flight since I put my new Blackhawk’s on and still have power to spare.
