MOONEY M20M TLS Model Guide
MOONEY M20M TLS · Model Guide
Overview
The MOONEY M20M TLS is a four-seat, turbocharged, retractable-gear single, described in a 1989 AOPA flight report. It has a Lycoming TIO-540 rated at 270 hp. The report calls its 3,200 lb gross weight the highest of any Mooney and lists 223 kt best-power cruise at 25,000 ft. It carries 90 usable gallons of fuel.
- Max takeoff weight is 3,200 lb and empty weight is 2,012 lb, leaving 1,188 lb useful load. Full fuel plus three 170-lb occupants fits, per the 1989 report.
- 270 hp intercooled TIO-540: 223 kt at 25,000 ft best power (20.9 gph); 202 kt at 19,000 ft best economy (16.6 gph).
- 90 usable gallons gives about six hours at 180 kt at FL180 with IFR reserves. Flying high means managing oxygen.
- Turbocharger service bulletins (ASB 074, SB 040) apply to Mooney turbo installs. Check the records for compliance.

Performance and fuel
Sea-level climb is 1,230 fpm, and climbing to 12,000 ft at gross weight takes about 10 minutes. Best-power cruise at 12,000 ft is 195 kt at 20.4 gph. At best power the report gives 208 kt at 17,000 ft, 212 kt at FL190 and 223 kt at FL250. The approach speed is a low 75 kt.
Airframe and systems
It has a dual alternator system and two batteries, one in the tail. It also has a three-blade McCauley 75-in prop, speed brakes and electric cowl flaps. The 270 hp limit comes from the airframe and controllability, not the engine. Recommended TBO is 2,000 hr. The report notes a strong nose-down pitch when flaps are extended.
What to check when buying
Verify turbocharger part numbers and center housing history against ASB 074 and SB 040, using the data plate rather than paperwork alone. Review engine logbooks closely. One sample logbook shows a 2010 return to Lycoming for disassembly and inspection, and a June 2014 sudden stoppage inspection.

Safety notes
- ASB 074: Aeroforce center housings P/N 441320-12 shipped 10 May to 1 Nov 2017 may have undersized bearing bores. This can cause bearing wear and turbocharger seizure.
- ASB 074 compliance for single-engine aircraft: above 30 in MAP at takeoff, before next flight. At 30 in MAP or less, within 10 hours or at the next scheduled inspection.
- SB 040: machining debris in some turbo center housings can seize the shaft and cause loss of engine power. It applies to units with up to 50 hours time in service.
