A Brief History of the Cessna T310Q
The Cessna 310 series was introduced in 1954 and rapidly earned a reputation for reliability, speed, and twin-engine redundancy. The T310Q variant, introduced in 1969, was one of the more advanced models in the series, offering turbocharged powerplants and aerodynamic refinements. Designed for performance at altitude and longer range, the T310Q was popular among charter operators, private business owners, and pilots in mountainous regions.
This model marked the 15th year of Cessna’s twin-engine evolution. The turbocharged engines gave it improved high-altitude climb rates and cruise performance over earlier models. With a useful load of 1,650 pounds and long-range 180-gallon fuel capacity, the T310Q is suitable for both business and personal cross-country flying.
Cessna Aircraft Company – A Legacy of Reliability
Cessna, founded in 1927, is one of the most trusted and prolific manufacturers in general aviation. Known for its single and twin-engine piston aircraft, as well as business jets, Cessna established a reputation for aircraft that are easy to maintain, economical to operate, and engineered for longevity. The 310 series was Cessna’s first twin-engine aircraft after WWII and set the stage for the company’s dominance in the light twin market.
Even today, aircraft from this era—especially examples with excellent records like N310D—continue to serve pilots well, reflecting the brand’s core values: reliability, simplicity, and value.
Maintenance, History, and Known Flaws
One of the most compelling aspects of this aircraft is its excellent records. All logbooks are present, with no gaps. There is no known corrosion, and the aircraft has seen consistent care and documentation.
A 1999 incident is noted where the aircraft, then registered as N433P, experienced a left engine overheat due to a defective ground wire. The aircraft returned to base and was repaired without further issue. Since then, it has remained incident-free.
Known Flaws:
- Prop sync is inoperative.
- Engine instrument lighting inoperative (red headlamp on co-pilot yoke).
- Autopilot altitude hold works; NAV tracking is unreliable.
- Nose paint is chipped. This is due to installation of non radar nose, no incidents
These issues are minor and well-documented, giving potential buyers transparency and confidence in what to expect.
Uses and Ideal Missions
With strong high-altitude performance, turbocharged redundancy, long-range fuel tanks, and IFR capability, N310D is suitable for:
- Mountain flying (ideal for Colorado, Idaho, Montana)
- Long-range cross-country flights
- IFR operations
- Family or business travel
- Multi-engine time building
Its excellent records, corrosion-free condition, and robust equipment list make it an ideal candidate for pilots who want reliability and real performance on a reasonable budget.
Airframe
This 1969 Cessna T310Q, serial number 310Q0002 and registered as N310D, has 4,865 hours total time and remains structurally sound with no known corrosion. The aircraft received a fresh Annual inspection on January 7, 2025, ensuring its continued airworthiness. Equipped with 180-gallon long-range fuel tanks, this T310Q is capable of stretching its legs to 1,200 nautical miles, minimizing fuel stops on cross-country trips.
It cruises efficiently at 220 mph at 75% power and stalls at 87 knots indicated airspeed with gear and flaps up, a testament to its aerodynamic efficiency. The useful load is 1,650 pounds, allowing for a full complement of passengers and luggage.
Unlike many other airframes of its vintage, N310D is corrosion-free and carries complete, unbroken logbooks, giving confidence in its condition and value.
Engines
N310D is powered by a pair of Continental TSIO-520-NB engines, each producing 285 horsepower. These engines are turbocharged and rated for high-altitude performance, giving the T310Q a strong climb rate even when operating from mountainous terrain.
- Left Engine: Serial Number 234112-R
- Right Engine: Serial Number 234108R
- Time Since Major Overhaul (SMOH): 1,454 hours each
- Date of Overhaul: February 21, 1983
- Overhaul Shop: Hants and Sussex Aviation
While the engines were last overhauled over four decades ago, their moderate SMOH numbers and consistent maintenance under excellent records make them viable powerplants for continued service. For a buyer intending heavy use, this might be a good opportunity to factor engine refresh into future planning.
Propellers
The aircraft is fitted with McCauley 3AF32C528-A constant-speed, three-blade aluminum propellers on both sides, installed on October 7, 1998. With 1,606 hours since new, these props are well within their operational lifespan. Blade models are G-82-NEA-4, with blade serials listed in detail, another testament to the thorough records maintained on this aircraft.
Smooth and responsive, these props contribute to quieter, more efficient performance and are ideal for mountain flying, where thrust and blade efficiency at altitude are essential.
Avionics
N310D comes well-equipped for IFR flight and situational awareness, combining classic navigation tools with modern weather and communication technology. This aircraft is IFR capable and was IFR-certified as of December 18, 2024, making it flight-ready for instrument operations.
