More Power for Mission Success

The Blackhawk Aerospace C-12 Lifecycle Extension Program extends the operating life of legacy aircraft by exchanging obsolescent engine, propeller systems, and avionics with the modern, high-performance technology. The program includes new higher horsepower PT6A-52 engines, powerful composite MT-Propeller 5-blade props, and the advanced Garmin G1000 NXi integrated cockpit. The result is a high-performance transport aircraft with the power, performance, and capability to expand mission support while lowering operating costs. The C-12 Lifecycle Extension Program reduces fuel costs by $45,000 and maintenance costs by $42,000 annually per aircraft. 

For more than 20 years, Blackhawk Aerospace has conducted engineering evaluations and developed engine and propeller replacement solutions that boost aircraft capabilities. Our lifecycle extension program and performance upgrades solve obsolescence issues associated with legacy engine and propeller systems while dramatically expanding mission capabilities. With more than 37 aircraft performance upgrade solutions installed on 1,000+ military and commercial aircraft worldwide, Blackhawk Aerospace solutions deliver higher performance and increased safety margins in all levels of flight. 

Lifecycle Extension Program Benefits

See full list of what is included below.

Brand new PT6A-52 engines deliver more horsepower, letting you climb faster, increase payload, cruise at higher speeds, arrive sooner, and do more.

  • 31% increase in available horsepower – for increased capabilities
  • 25% increased climb rate – get to altitude faster
  • 311+ KTAS max cruise speed – arrive on station sooner
  • Full torque to FL260 – fly higher for greater fuel savings

Fast and lightweight, 5-blade composite MT-Propellers props allow you to experience the full potential of your new, more powerful engines.

  • Composite construction reduces overall weight while increasing strength
  • Reduced vibration extends sensitive aircraft component life
  • More lift and thrust due to lower tip speeds that maintain smooth airflow
  • Unlimited blade life as composite blades are brought back to new condition during overhaul, avoiding replacement
  • Quieter as a result of shorter and smaller diameter blades, increased blade count, and slower tip speeds

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!

  • Won’t an upgrade cost more than an overhaul?

    Yes, you’ll spend more on an upgrade than an overhaul, but you’ll have so much more to show for it: increased earning ability, better resale value, enhanced safety, reduced operating costs and a better flying experience.

Stretch Your Budget

The Life Cycle Extension Program allows your operation to experience cost savings, helping you to do more with less.

  • Lower operating costs than stock engines
  • Pratt & Whitney core engine credits up to $60 per hour per engine for every hour remaining to the factory TBO
  • Strongest resale value of any engine upgrade on the market
  • 3,600 Hour TBO with escalation available for fleet operators
  • Faster speeds and climb save time on each mission and experience fuel savings

Formerly operated as Vector-Hawk, Blackhawk Aerospace Solutions formed in 2008 to bring vast engine upgrade and superior customer service capabilities to government agencies. Blackhawk soon won the Government of Israel’s engine and propeller MRO contract, which successfully continues to this day.

Soon after, L3 selected the company to help solve engine MRO management and repair cycle issues. Blackhawk successfully reduced L3’s average engine overhaul time from 120 days to 45 days, significantly reducing costs and downtime.

We understand the unique challenges facing today’s government and defense operators and how limited budgets push the limits of legacy aircraft.
