Mooney M20E Super 21 / Chaparral

Mooney introduced the M20E Super 21 in 1964 as the fuel-injected upgrade to the M20C Ranger. The major change was the engine: fuel-injected Lycoming IO-360-A1A at 200 hp replacing the carbureted O-360-A1D at 180 hp. Same airframe, same retractable gear system, same general dimensions and useful load. The 'Super 21' name reflected the 21-inch landing gear stroke that gave the M20-series its characteristic stance.

Mooney renamed the M20E to Chaparral in 1967 as part of a broader model-name update. Same airplane, same engine, just the model name change. Production continued through 1975 with about 1,400 M20E / Chaparral aircraft built. The variant ran in parallel with the M20C Ranger (carbureted entry-level) and the M20F Executive (stretched fuselage M20E) from 1966 onward.

Mooney ended M20E production in 1975 as the company prepared for the more aerodynamically refined M20J 201 (introduced 1976). The M20E and M20F became used-market-only after 1975. The fleet has remained popular with cross-country pilots who specifically want a fuel-injected Mooney at lower cost than the M20J or later variants. Mooneyspace.com provides excellent type-specific resources for M20E ownership.

The M20E cruises at about 155 KTAS at 75% power, burning 10.5 gph of 100LL. At long-range cruise (65%), the airplane drops to about 145 KTAS on 9 gph. The M20E is meaningfully faster than the M20C (about 10 to 12 knots) on slightly higher fuel burn due to the additional 20 hp. Cruise efficiency is excellent. The M20E achieves competitive Mooney performance at lower acquisition cost than the M20J 201.

Useful load on an M20E is about 900 to 950 pounds, essentially identical to the M20C. Full fuel (52 gallons usable) leaves about 600 to 650 pounds for people and bags. The compact Mooney cabin works for two adults plus full bags or four adults plus minimal bags. The airplane is built for cross-country efficiency, not four-passenger comfort. Range with reserves is about 800 nm at long-range cruise. Service ceiling is 19,500 ft on paper.

The Lycoming IO-360-A1A is the engine on every M20E. It's a four-cylinder, horizontally opposed, fuel-injected, direct-drive piston rated at 200 hp at 2,700 RPM. Lycoming's published TBO is 2,000 hours per Lycoming Service Instruction 1009 BE. The IO-360-A1A is a higher-compression variant than the IO-360-C series used in Pipers, designed specifically for the Mooney application.

Field overhauls at Penn Yan, Gann Aviation, or other reputable Lycoming shops run $33,000 to $46,000 in 2026 prices. The IO-360-A1A is moderately more expensive to overhaul than the carbureted O-360 in the M20C due to fuel injection components but cheaper than turbocharged variants. Parts availability is excellent through the broader IO-360 community.

Oil consumption on a healthy IO-360-A1A runs about 0.15 to 0.25 quarts per hour. The engine reaches TBO routinely when operated regularly. The constant-speed propeller (Hartzell two-blade or McCauley two-blade) requires overhaul concurrent with the engine. Prop overhauls run $2,500 to $4,000.

Plan on $185 to $255 per flight hour at 100 hours a year of utilization, all-in. The M20E's operating cost is roughly $20 per hour above the M20C due to the additional 20 hp and slightly higher fuel burn. Fuel and oil run about $58 to $74 per hour at 10.5 gph and $5.50 to $7 for 100LL. Engine overhaul reserve is $17 to $23 per hour. Prop reserve adds $1.25 to $2.00 per hour. Airframe maintenance reserve is $28 to $42 per hour due to Mooney-specific items (fuel tank reseal cycles, gear system).

Annual fixed costs (hangar, insurance, annual inspection) add another $55 to $100 per hour at 100 hours a year of utilization. Insurance is moderate. First-time retract owners pay $3,200 to $5,800 a year typically. Established Mooney pilots with 200+ hours in type pay $2,000 to $3,800.

Acquisition cost in mid-2026: An M20E with mid-time engine and steam-gauge panel runs $75,000 to $115,000. An M20E with fresh engine and modern Garmin panel runs $115,000 to $145,000. Aircraft with documented recent fuel-tank reseal trade at premiums.
