Frequently Asked Questions

  • Can my shop do the installation or does Blackhawk have to do the installation?

    Blackhawk does not perform installations. Although the installation is basically an engine change and can be done by any Pratt & Whitney Canada certified facility, we have found that you will save time and money if the upgrade is performed by any of our approved installation facilities worldwide. These facilities have the experience to complete the upgrade faster and with the higher exacting quality you demand.

  • What is the lead time on engine(s)?

    Blackhawk orders all engines a year in advance. We can usually deliver within 30-60 days or sooner. Call for timing on the next set of available engines.

  • Do you offer financing?

    Yes. We work with several banks that offer very competitive rates.

  • How does the Blackhawk XP Engine+ Upgrade affect resale value?

    To date, nearly every Blackhawk powered aircraft that has been resold within 500 hours of the upgrade has sold close to or higher than the combined investment of the airframe and engine(s). Resale value of Blackhawk powered aircraft remains strong in all markets. Many dealers are even speculating on Blackhawk powered aircraft.

  • How is Blackhawk different from other upgrades or overhaul?

    In addition to worldwide product support and product branding, Blackhawk XP Engine+ Upgrades offer the following benefits:

    • Listings in Jetnet, AMSTAT, Aircraft Bluebook, and Vref
    • Worldwide market acceptance with the largest installed fleet of upgraded corporate size turboprop aircraft in the world
    • Full customer support department with on-staff technical support technician, customer service representative, and worldwide distribution and service center network
    • The Blackhawk Owner’s Group
    • The strongest resale value of any engine upgrade on the market
    • Approval by the FAA (United States), EASA (Europe), DGAC (Brazil)
  • Can I put my airplane on charter?

    Yes. In fact, many charter companies prefer operating aircraft upgraded with a Blackhawk XP Engine+ Upgrade because they are able to operate out of shorter, higher, and hotter runways.

  • Can I keep my core engine?

    Since the upgrade price already reflects the value of the cores, you can keep your core engine if you are willing to pay Pratt & Whitney Canada for the core. Prices will depend on core engine times.

  • My engine(s) still have time left to TBO, so should I wait until engines are due for an overhaul?

    Pratt & Whitney Canada (PW&C) offers an engine credit for every hour remaining to the factory TBO. To qualify, the core engine must have enough cycles on the life-limited components to make TBO and all records supporting the component times and cycles must be present and submitted. Waiting until TBO risks the possibility of a core engine problem, resulting in additional core charges from PW&C. Also, prices from P&WC increase every year, so waiting two or three years would mean a higher investment without any of the time-remaining credit.

  • How does an upgrade compare to buying a newer aircraft?

    Blackhawk offers transformative performance without the risks of buying new: Will you be able to sell your aircraft for the value you expect? Will there be unexpected costs to acquire your new aircraft? Will there be unexpected issues not uncovered by the pre-buy? Upgrading with Blackhawk eliminates uncertainty and the transactional costs of buying another aircraft while transforming the performance and utility of the aircraft you know best.

  • If I upgrade, does it make sense to wait until my next overhaul?

    Why wait to start enjoying the many benefits of an upgrade? Save money on every mission you fly, increase the capability of your aircraft, and take advantage of generous core credits for time remaining. Over half of Blackhawk’s customers upgrade with more than 500 hours remaining.

  • But won’t I burn more fuel?

    Yes, the fuel burn is greater at equal altitude. However, taking advantage of the increased climb performance and higher cruise speeds significantly narrows or eliminates the increase in fuel consumption. Also, utilizing the increased climb and cruise performance will reduce block times and deliver a significant reduction in overall operating costs. Typically, any increase in fuel cost will be offset by a larger reduction in direct operating costs. We’ve done the math, it pays to fly faster!


From real XP135A (Cheyenne) owners and operators

  • 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.

    Michael Miklus

  • 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.

    Jim Costello

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

    Randy Kerns

  • 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!

    Dan Rogers

  • 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.

    Jeff Mickler

  • 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!
