For Models MU-2F & G 

How would you like your MU-2 to cruise up to 293kts  (F model) while gaining single engine performance, climb performance, and hot day/high density altitude performance??? Well National Flight Services has the modification for you! National Flights compressor section modification for TPE331-1-151A's replaces the old style, 705hp compressor section with a newer style, 840hp compressor. Not only does this allow your -1 to breath better, it gives you 705hp at higher altitudes, one of the benefits of our Super One Conversion.

• Increased air speed at higher altitude  - Up to 293kts on the F model!
• Incorporates a modern compressor configuration
• Improved hot day – high-density altitude
• Improved single engine performance
• Less thermal distress - increased cooling
• Reduced maintenance costs at scheduled inspection intervals

The modification can be added at anytime and is a great addition at either hot section or overhaul intervals. Contact one of our four service center locations for more information!
