Covers XP67A Engine+ Upgrade On King Air 350 Series

Blackhawk Aerospace announced it has received FAA certification for its XP67A Engine+ Upgrade with the MT 7-blade composite propeller on the Beech King Air 350 series aircraft. The approval introduces a new level of performance, efficiency, and comfort in the turboprop market.

The 7-blade prop was certified by MT Propeller in Germany in conjunction with BLR Aerospace and is built on the previously certified 5-blade Whisper Prop. The new 7-blade propeller improves climb rate, cruise speed, and fuel efficiency and at the same time reduces cabin noise and vibration fatigue.

The propeller offers several advantages:

• Quiet Propeller for King Air – Certified for low takeoff noise, delivering a noticeably quieter cockpit and cabin.
• Superior Aerodynamics – Reduces vibration fatigue with a 45% higher damping coefficient, enhancing longevity of aircraft systems.
• Fuel Savings & Smooth Taxiing – No RPM restrictions during ground operations, minimizing brake wear and optimizing fuel efficiency.
• Enhanced Durability – Nickel-cobalt leading-edge blade protection for superior resistance to erosion and damage.
• Simplified Maintenance – On-aircraft repairs and in-field blade replacements without hub changes.

The XP67A Engine+ Upgrade is based on the Pratt & Whitney PT6A-67A turbine engine.

Edwin Black, President at Blackhawk said, “At Blackhawk, we’re always looking for ways to help our operators get more performance, efficiency, and value out of their aircraft. The certification of the 7-blade Whisper Prop® with our XP67A Engine+ Upgrade is a huge win—it’s quieter, smoother, and makes an already incredible upgrade even better.

“We’re proud to offer this upgrade alongside MT Propeller and BLR Aerospace to bring this innovation to the King Air community.”
