Propeller upgrade
The MT-Propeller STC fits the Cheyenne III and IIIA with PT6A-41 or PT6A-61 engines. It replaces 3-blade Hartzell or 4-blade McCauley propellers with two 4-blade reversing, full-feathering composite props. Each prop and spinner with deice weighs 113 lbs. The maker claims about 60 lbs less weight, 4 to 5 kts more cruise at 1800 RPM, and 4 to 6 dB(A) less cabin noise.
Brakes and landing gear
Cleveland conversion kit 199-112 (STC SA600GL) fits the PA-42 and PA-42-720 and uses MIL-H-5606 brake fluid. Its metallic linings need conditioning: two consecutive full stops from 30 to 35 kts. CASA bulletin AWB 32-005 lists the PA-42 Cheyenne III. It recommends lubricating the gear down-lock and rod-end parts every 50 hours plus or minus 5 hours.
Support and options
Piper lists parts catalog 761-717 for the PA-42 and -42-720, with a separate 761-818 for the Cheyenne IIIA Advanced Trainer. A stretcher kit (STC SA00961WI) mounts on the existing seat rails after the seats on one side are removed. Service Bulletin 1041 requires inspecting Airborne air filter elements and the gyro vacuum/pressure system.
Summary written by AI from the source document. Check the original before relying on it. See which parts of Sprinkle are written by AI.
Safety notes
- A landing gear down-lock failure to latch led to a gear-up landing in a PA-31-350 Chieftain; the AWB 32-005 advice also covers the PA-42.
- Unconditioned metallic brake linings wear faster and the discs can score; repeated high-speed stops can overheat and warp discs.
- Loose particles from Airborne air filter elements can contaminate the gyro vacuum/pressure system; confirm Service Bulletin 1041 compliance.
