Normal Procedures for the Piper PA-46 Malibu Mirage

propeller control lever. The control arm can be reindexed on the shaft for large adjustments (7-15°) by removing the control shaft nut and washer (see Figure 1). Reposition the arm on the control shaft hex key as necessary. The control arm can be moved in smaller increments by flipping the arm and using the double-cut hex pattern. Reinstall arm, washer, nut and torque to 72-96 in-pounds. The control head can also be rotated for small adjustments (~1°) if necessary to utilize the full travel of the propeller control lever. To adjust the head, loosen the six socket head cap screws securing the control head. Rotate the control head as necessary and snug the screws finger-tight. After adjustments are complete, remove the six mounting screws individually, coat threads of screw with Loctite 242 and torque the screws holding the cable bracket to 21-25 in-pounds (Note: that is inch-pounds, NOT foot- pounds).

NOTE: It is recommended that a person be stationed touching the de-ice boots while the functional test is conducted to warn of any unintended de-ice boot heating. D1. D2. With engine off, turn on battery master and note the voltage on the aircraft voltmeter. Turn on auxiliary cabin heat and blower; note voltage level (drop) on main voltmeter.

INST_080808_97FLD INSTRUCTIONS FOR FIELD INSTALLATION of a HARTZELL HC-13YR-1N/N7605(K)+2 or HC-13Y1R-1N/N7605(K)+2 PROPELLER and D-6750-1(P) SPINNER ON PIPER PA-46-350P (MALIBU MIRAGE) AIRCRAFT Serial Number 4622001 to 4622200 and 4636001 to 4636131 Turn on propeller de-ice. Note the aircraft voltage increase. The increase verifies that the auxiliary cabin heater is shut off through the switch interlock. Verify that propeller de- ice current is zero. Zero de-ice current indicates that the "squat" switch lockout is functioning properly. Next, with prop heat still on, push the propeller de-ice "push to test" (surface de-ice) switch. The propeller de-ice ammeter should indicate current flow, which verifies that the test function is working properly. Note heating of de-ice boots through touch. NOTE: Normal de-ice current (green arc) may not be achieved on battery power. Shut off all aircraft electrical equipment. Turn on the propeller de-ice and note zero prop de-ice current. With the propeller de-ice still on, depress the “squat” switch on the left main landing gear. The propeller de-ice ammeter should now indicate current flow. This verifies that the squat switch circuit functions properly allowing de-ice function in flight (with weight off the wheels). Shut off all aircraft electrical equipment. Jack aircraft and swing the landing gear to ensure that the landing gear ground lockout/squat switch system still functions properly. With aircraft secured, start engine and cycle propeller several times to fill the propeller cylinder with oil. At 1200 RPM, turn on prop de-ice and depress test button. Prop de-ice ammeter should be in the normal operating range (green arc). Shut down engine. Check engine oil level and replenish as necessary. Section E, Documentation E1.

Revise weight and balance records to show the removal of the original propeller and spinner (and governor if applicable) and the addition of the following equipment at the same moment arm: Weight (pounds) Propeller, Hartzell (HC-13YR-1N/7605K+2) 63.5 Or, propeller, Hartzell (HC-13Y1R-1N/7605K+2) 59.0 Spinner, Hartzell (D-6750-1(P)) 5.0 Governor, Hartzell S-1-30 (optional) 3.3 E3. E4. E5. Note: For aircraft without propeller de-ice subtract 0.8 pounds from the propeller weights above. Make aircraft logbook entry and return aircraft to service with FAA Form 337 referencing STC. Perform a functional check-flight using normal procedures, note maximum RPM setting and readjust governor high-RPM stop if necessary. Post-installation dynamic balance of the propeller/engine combination is recommended but not required. Dynamic balance information is provided in the Maintenance Practices section of Hartzell Owner's Manual 145. INST 080808_97FLD.doc
