NOTE 5. Cylinder base temperature limits are not applicable to engine models which incorporate internal piston cooling oil jets. NOTE 6. Spark plugs approved for use on these engines are listed in the latest revision of Lycoming Service Instruction No. 1042. NOTE 7. Description TIGO-541-C1A-Basic model. Six cylinder air cooled, hor izontally-opposed, geared drive, fuel, injected, top induction, down exhaust, turbocharged engine incorporating internal piston cooling oil jets, side mounted accessory drives and a single oil supply from prop. gov. Provision is also made for installation of reverse pitch propeller control. NOTE 7., cont. -D1A - Similar to the -C1A except ha s higher power rating and uses a different turbocharger with provisions for cabin bleed air. -E1A - Similar to the -D1A except has lower power rati ng with different turbocharger spring rate and variable absolute pressure controller. -B1A - Similar to the -C1A except has higher power rating and does not incorporate provisions for cabin bleed air. -G1AD - Similar to the -D1A except in corporates an intercooler, dual magneto and a fuel injector employing fuel head enrichment. -D1B - Similar to -D1A except has an integral wast egate turbocharger with revised exhaust system and incorporates low drag cylinders. NOTE 8. The propeller shaft has a 2:3 ratio to crankshaft rota tion and is positioned 4.92 in. above crankshaft centerline. Propeller rotation is counter clockwise and crankshaft rotation clockwise as viewed form the engine anti-propeller end. Propeller shaft provides a 5 1/4 in. O.D. flange with a 4.25 in. dia. bolt circle. NOTE 9. Air from the compressor of the Kelly Aero space (formerly AiResearch) models T-1879 and T18A21 turbochargers is suitable for cabin pressurization. The installation must provide for cabin air temperature control from 300°F to temperature at 20,000 feet (hot day conditions - maximum engine power). For cabin air inlet flange dimensions see Lycoming Dwg. No. 63270 for -C1A, No. 63303 for -D1A and E1A, No. 63435 for - G1AD, No. 63468 for -D1B. A sonic nozzle must be provided to preclude a ffecting engine performance by cabin air bleed. NOTE 10. With maximum oil temperature, the maximu m nose up is 17° and the maximum nose down is 15°. - END - ``` ## ADs (18, in force first) - [AD 2026-04-11](https://openairdocs.org/ad/2026-04-11): Engine (Reciprocating) · Lycoming Engines AEIO-320-D1B, AEIO-320-D2B, AEIO-320-E1A and 605 more.
