For Sale: N612SP—$92,000

N612SP is a lovely Cessna 172SP manufactured in 2000. I hate to sell it, but I was forced to let my medical certificate lapse and can no longer fly it.

The Plane

Engine and Propeller

The plane’s 180 horsepower engine powers the plane along at a respectable 124 knots at 8,500 feet with 75 percent power. At the recommended lean mixture with fuel allowances for engine start, taxi, takeoff, climb, and 45 minutes reserve, the plane can fly 518 nautical miles (4.26 hours). Climb to 10,000 feet, throttle back to 45 percent power, and you can extend your range to 638 nautical miles (6.72 hours). The long-range tanks carry a maximum of 53 gallons of usable fuel.

The plane has a Lycoming IO–360–L2A engine. The IO–360–L2A engine has four horizontally opposed cyliders. It is normally aspirated, direct drive, air-cooled, and fuel-injected, and it has a total displacement of 360 cubic inches. It uses 100LL aviation fuel (blue) and MIL–L–22851 aviation grade ashless dispersant oil (e.g., AeroShell W 100). The tach time on the engine is 1,985 hours. The compressions at the last annual were 73/80, 72/80, 70/80, and 74/80. It consumes very little oil.

The McCauley propeller has two blades, fixed pitch.


The plane comes with a well-integrated set of Bendix/King avionics:

Weight and Balance

The plane has a maximum ramp weight of 2558 pounds and a maximum useful load of 882 pounds.

**Takeoff Weight and Moment      
* The maximum allowable combined weight capacity for baggage areas 1 and 2 is 120 pounds.
** Divide the moment by the weight to compute the center of gravity. At maximum gross weight (2,550 lbs.) the center of gravity must be between 41 and 47 inches. As the plane’s weight decreases towards 1,950 lbs., the forward limit of the center of gravity approaches 35 inches.

Damage History and Logbooks

The plane incurred no damage while I owned it. A December 20, 2002, entry in the airframe logbook states, “Removed engine from firewall and replaced lower firewall assembly. Reinstalled engine to firewall and torque mount.”

The plane’s logbooks are complete. You may download them here.

Interior and Exterior

During the ten years that I have owned the plane I have always used a Bruce’s Canopy Cover or parked the plane in a hanger. As a result, the plane’s interior is in superb condition.

The Matterhorn white paint, which covers the entire exterior of the plane is in good shape. The decal material that Cessna uses to add colors and lettering to late-model 172s is weathered in places, especially on the nosewheel wheelpant. Cessna paints the metal surfaces of its late-model 172s with an undercoat of green, anti-corrosion paint. To the best of my knowledge this plane does not have any corrosion.
