Cessna 421B Riley Turbine

Aircraft Information

Serial Number: 
Registration Number: 
Aircraft Description: 

The perfect combination of the Cessna Golden Eagle’s cabin comfort and Honeywell’s turboprop smoothness and performance. N59NM is equipped with a pair of recently hot sectioned Honeywell LTP-101A/600’s designed to 600 SHP but thermally flat-rated to 475 SHP! This enables N59NM to cruise at speeds approaching 230-knots on 55-gallons per hour in a whisper quiet cabin! The Garmin avionics upgrade with MFD, EFIS and a digital autopilot complete the instrument panel.
