N644AT Aircraft Overview
Performance Profile
N644AT's Cessna Citation III cruises at 480 knots with a range of 2,000 nautical miles. The 2x Honeywell TFE731-3B-100S produce 3,650 lbs per side, supporting a service ceiling of 51,000 feet.
Mission Profile
The Cessna Citation III seats up to 9 passengers in a 18.3 ft by 5.5 ft by 5.7 ft cabin. N644AT delivers the stand-up headroom and seating configurations that distinguish midsize jets from their light-jet counterparts.
Charter Authorization
N644AT's operator holds Part 135 authorization. The Cessna Citation III's 2,000 NM range and 9-seat cabin cover the domestic missions that drive the highest charter demand.
Insider Note
Buyers comparing midsize jets should focus on three variables: engine program enrollment, avionics generation, and interior condition. N644AT's manufacture date and active Part 135 status suggest the aircraft is maintained to revenue-service standards, which typically exceeds Part 91 maintenance requirements.
Charter & Acquisition Briefing
Registration N644AT is a Citation held by . Cessna has delivered over 3,500 aircraft in the straight-wing Citation family. This briefing covers charter economics and acquisition reality.
Fleet Position
Over 3,500 straight-wing Citations were produced, making it the most numerous business jet family in history. FAA data shows N644AT based in —, . Parts support and maintenance expertise are ubiquitous: every Cessna-authorized service center in the U.S. can maintain these aircraft. No other business jet has deeper parts inventory or more available mechanics.
Charter Availability
N644AT is Part 135 charter authorized. Straight-wing Citation charter rates range from $2,200 to $3,800 per flight hour depending on variant. These are among the most affordable jet charter options available. The tradeoff is speed and range: straight-wing Citations cruise at 350 to 420 knots with 1,500 to 2,000 nm range, adequate for regional operations but limited for transcontinental routes.
Mission Profile
Optimized for corporate shuttle and air ambulance missions where reliability and operating costs matter more than speed. The Citation's straight wing design produces lower approach speeds and shorter landing distances than swept-wing jets, opening hundreds of regional airports that faster jets cannot access.
When to Choose Something Else
Skip the straight-wing Citation for coast-to-coast routes. Published range of 1,500 to 2,000 nm requires a fuel stop on transcontinental legs. For nonstop LA to New York, step up to a CJ3 (2,040 nm) or Citation Sovereign (3,000 nm).
Ownership & Operations
Aircraft ownership in the United States falls under FAA registration requirements. Every U.S.-registered aircraft carries an N-number that links to public records including owner name, address, airworthiness date, and certificate type. The FAA Aircraft Registry maintains this data and updates it as aircraft change hands. Prospective buyers use these records to verify ownership history, lien status, and maintenance compliance before committing to an acquisition.
Pre-Purchase Considerations
Avionics modernization drives both capability and market value. Aircraft with legacy analog instruments trade at significant discounts to those with modern glass cockpits (Garmin G5000, Collins Pro Line Fusion, Honeywell Primus Epic). ADS-B Out compliance is now mandatory in U.S. controlled airspace. Buyers should factor avionics upgrade costs into their acquisition budget when evaluating older airframes.
Charter Market Context
Empty leg pricing offers 25 to 75% discounts on published charter rates. These opportunities arise when an aircraft needs to reposition from a drop-off point back to base or to the next pickup location. The tradeoff is schedule inflexibility: departure time, date, and route are fixed by the operator's existing itinerary. The Jet Finder maintains an empty leg alert system for frequent charter clients.
