N309SF

This article covers airframe N309SF, a Dassault Falcon 50 built in 1981 with manufacturer serial 29. The aircraft is registered in the US and is currently owned by VALLEY AIR EXPRESS INC of Cheyenne, Wyoming, a corporate owner/operator listed as the on-record custodian. No detailed public chronology of prior registrations or transfers is available; registry actions beyond current ownership are Not published. Condition and valuation highlights show an estimated market value of $1,500,000, reflecting an older airframe in operational corporate service with attendant maintenance and refurbishment considerations typical of early-1980s business jets.

The cabin for this airframe is a typical eight–ten place executive layout, described as a Typical 8–10 place executive layout, configured for up to 10 occupants in executive seating. Avionics fit for N309SF is Not published in the available data; operators commonly retrofit Falcon 50 airframes but no specific avionics upgrades are recorded here. Typical mission profiles for this aircraft, supported by a 3,057 nm range and 420 kt cruise, would include transcontinental and regional business charters, medevac or corporate transport from its home base in Cheyenne, Wyoming. Given the aircraft age (built 1981) and triple Honeywell TFE731 engines, maintenance considerations emphasize engine shop visits, structural inspection cycles and avionics modernization when required by the operator to meet contemporary regulatory and operational expectations.

The Dassault Falcon 50 family occupies the mid-size, long-range trijet niche, notable for transcontinental capability and a high service ceiling of 49,000 ft. In the used-aircraft market, older Falcon 50 examples from the early 1980s are valued for their range and performance but trade at depressed prices relative to newer light and midsize business jets; this example is appraised at $1,500,000. Buyer and charter demand tends to favor examples with recent avionics upgrades and well-documented maintenance; for N309SF, the age, three-engine maintenance profile and specified engine model (Honeywell TFE731-3-1C) are primary factors affecting resale and operational cost considerations.
