The Falcon 900: Three Engines and a Short-Field Secret

Why Dassault Built a Tri-Jet

Marcel Dassault signed off on the Falcon 900 program in 1983. The aircraft first flew in September 1984 and received DGAC certification in March 1986. Dassault chose a three-engine configuration for reasons that had nothing to do with fashion. In the early 1980s, ETOPS rules restricted twin-engine aircraft from routes more than 60 minutes from a diversion airport. Three engines meant unrestricted overwater routing from day one.

The original Falcon 900 carried three Honeywell TFE731-5AR engines producing 4,500 pounds of thrust each. Total thrust: 13,500 pounds distributed across three lightweight turbofans. The center engine feeds through an S-duct intake above the fuselage. That intake design is a Dassault signature shared with the Falcon 7X and 8X. It allows the fuselage to maintain a clean cross-section without the drag penalty of a straight-through center engine nacelle.

ETOPS restrictions have since loosened. Twins fly everywhere today. But the Falcon 900's three-engine architecture delivered a second advantage that remains relevant 40 years later: short-field performance that no twin-engine heavy jet can replicate.

The Variants: From 900 to 900LX

Dassault produced four major variants of the Falcon 900 over its production run. Each iteration improved range, avionics, and mission capability while maintaining the airframe's fundamental geometry.

Falcon 900 (1986-1991)

The original. Three TFE731-5AR engines, 3,700 NM range, analog Collins avionics. Approximately 100 delivered. These airframes trade between $1.5 million and $3 million today depending on engine time and interior condition. Many have been retired or converted to cargo operations.

Falcon 900B (1991-2000)

Upgraded TFE731-5BR engines with 4,750 lbs thrust each. Range extended to 4,000 NM. Improved fuel efficiency and reduced maintenance intervals. Approximately 90 delivered. These hold $2 million to $5 million in the secondary market.

Falcon 900EX (1996-2008)

The first major redesign. New TFE731-60 engines with 5,000 lbs thrust. Range jumped to 4,500 NM. Digital EASy flight deck replaced analog gauges. This is where the Falcon 900 became a genuine transatlantic aircraft. Approximately 220 delivered. Trades at $4 million to $10 million.

Falcon 900LX (2008-2018)

The final production variant. Same TFE731-60 engines as the EX but with redesigned winglets and aerodynamic improvements that pushed range to 4,750 NM. The LX added blended winglets that reduced drag by 3-4% and improved field performance. Approximately 130 delivered. Trades at $7 million to $15 million.

Short-Field Performance: The Defining Advantage

The Falcon 900LX takes off in 4,675 feet and lands in 2,380 feet at sea level, ISA conditions. For a jet with 4,750 NM of range and a cabin that seats 12, those numbers are exceptional. The Gulfstream G450 needs 5,300 feet for takeoff. The Challenger 604 needs 5,460 feet. Neither can approach the Falcon's landing distance.

Dassault also certified the 900 series for steep approaches. London City Airport requires a 5.5-degree glideslope. Standard ILS approaches use 3 degrees. The Falcon 900 is one of the few heavy-cabin jets certified for London City operations. That certification opens airports across Europe, including Lugano, St. Tropez, and several Swiss mountain fields that reject other heavy jets entirely.

Who Flies the Falcon 900 Today

The FAA registry lists approximately 180 Falcon 900-series aircraft with active U.S. airworthiness certificates. Corporate flight departments operate the majority. Part 135 charter operators hold roughly 30% of the active fleet. Government and military users, including the French Air Force (which operates a fleet of 900-series aircraft for VIP transport), account for a smaller but notable share.

The Falcon 900's owner profile skews toward operators who value European access. Companies with frequent London, Geneva, Nice, and Mediterranean routing choose the 900 specifically because its short-field envelope opens airports that Gulfstream and Bombardier heavy jets cannot reach. U.S.-based operators concentrated in the Northeast and Southeast corridors use the type for Caribbean and Bermuda routing where fuel stops at shorter island runways are sometimes necessary.

• Corporate flight departments: ~55% of active U.S. fleet
• Part 135 charter operators: ~30%
• Government/military: ~10%
• Fractional/management programs: ~5%

Maintenance and Ownership Realities

Three engines means three hot-section inspections, three overhauls, and three sets of engine mounts. The TFE731-60 on the EX and LX models has a TBO of 7,000 hours. Hot-section inspections hit at 3,500 hours. At 500 annual hours, an owner faces engine events every 7 years per engine, staggered so one engine is always approaching a shop visit.

Annual direct operating costs for a Falcon 900LX flying 500 hours run approximately $2.4 million to $2.8 million. That includes fuel, crew, insurance, hangar, landing fees, and maintenance reserves. The G450 at similar utilization costs $2.1 million to $2.5 million. The third engine accounts for most of the difference. Owners who fly fewer than 300 hours annually feel the fixed costs more acutely.

Dassault Falcon Service Network

Dassault operates factory-owned service centers in Teterboro (NJ), Little Rock (AR), Reno (NV), and several European locations. Factory service is a competitive advantage. Gulfstream and Bombardier also run factory service networks, but Dassault's vertical integration means airframe, engine, and avionics work can be coordinated under one roof. That reduces downtime and eliminates finger-pointing between separate MRO providers.

The Falcon 900's Place in 2026

Production ended in 2018 when Dassault shifted focus to the Falcon 6X and 10X programs. No direct replacement exists. The Falcon 8X covers the ultra-long-range segment. The 6X targets the wide-body super-midsize market. Neither replicates the 900LX's specific combination of 4,750 NM range, tri-jet short-field access, and moderate cabin volume.

On the charter market, 900LX airframes remain in steady demand for transatlantic and Caribbean routing. Hourly rates of $5,000 to $7,000 position the type between super-midsize jets ($3,500-$5,200) and ultra-long-range jets ($6,500-$10,000). For clients who need short-field access in a heavy-cabin jet, there is nothing else on the market that does exactly what the Falcon 900 does.
