Overview
This document provides Instructions for Continued Airworthiness for the Hartzell HC-I3YR-1N/N7605(K)+2 and HC-I3Y1R-1N/N7605(K)+2 propellers installed on Piper PA-46-350P (Malibu Mirage) and PA-46R-350T (Matrix) aircraft. It outlines the maintenance requirements and procedures necessary to ensure the airworthiness of these propellers. The document is intended for maintenance personnel and pilots who operate these aircraft models. Key sections include airworthiness limitations, maintenance checks, and troubleshooting procedures for the propeller de-ice system. It also specifies the recommended time-between-overhaul limits and provides guidance on inspections and repairs.
- The STC propeller is an 80" diameter, three-blade composite constant-speed propeller.
- The acceptable resistance range for de-ice boot circuits is 4.12 - 4.56 ohms.
- If all three blade heaters are checked in parallel, the acceptable range is 1.37 – 1.52 ohms.
- Operation of the propeller de-ice system without the engine running is limited to 10 seconds to prevent damage.
- Recommended Time-Between-Overhaul (TBO) limits are provided in Hartzell Service Letter 61.

Airworthiness Limitations
This section details the FAA-approved maintenance requirements under Sections 43.16 and 91.403 of the Federal Aviation Regulations. It emphasizes the importance of adhering to these limitations to maintain the airworthiness of the aircraft.
Time Limits / Maintenance Checks
All required maintenance, inspections, and time intervals are outlined in Hartzell Manual 145. This includes recommended Time-Between-Overhaul (TBO) limits for the STC propeller, which are also detailed in Hartzell Service Letter 61.
Propeller Heat System Description and Operation
The Hartzell propeller de-ice system consists of a multi-strand resistance wire heating element. The system operates on a 90-second ON, 90-second OFF cycle when activated, ensuring all blades are heated simultaneously.
Heater Boots Electrical Check
This section provides procedures for checking the electrical resistance of the de-ice boot elements. The acceptable resistance range is specified as 4.12 - 4.56 ohms for individual units and 1.37 – 1.52 ohms when checked in parallel.
Propeller Heater System Periodic Inspection
Periodic inspections of the propeller de-ice system should follow the guidelines in Hartzell Manual 145, ensuring that all components are functioning correctly and safely.
Safety notes
- CAUTION: OPERATION OF THE PROPELLER DE-ICE SYSTEM WITHOUT THE ENGINE RUNNING IS LIMITED TO 10 SECONDS OR SEVERE DAMAGE TO THE COMPOSITE BLADES MAY RESULT.

The Instructions for Continued Airworthiness below document the maintenance requirements and procedures associated with the new Hartzell HC- I3YR-1N/N7605(K)+2 and HC-I3Y1R-1N/N7605(K)+2 three-blade composite propellers installed on PA-46-350P aircraft S/N 4636132 and up and all serial numbers of PA-46R-350T aircraft. Chapter 4 – AIRWORTHINESS LIMITATIONS NOTE: The Airworthiness Limitations section is FAA approved and specifies maintenance required under Secs. 43.16 and 91.403 of the Federal Aviation Regulations unless an alternative program has been FAA approved. Chapter 5 - TIME LIMITS / MAINTENANCE CHECKS All required maintenance, inspections, time intervals and procedures are provided in Hartzell Manual 145 (Hartzell Propeller Owner’s Manual) provided with each propeller. Recommended Time-Between-Overhaul (TBO) limits for the STC propeller are also provided in Hartzell Service Letter 61. Chapter 30 - ICE AND RAIN PROTECTION For aircraft with electric propeller de-ice systems, the propeller de-ice system service information is provided on the system installation drawing 102960 and in specific Hartzell service manuals. These manuals can be viewed and/or obtained via the internet on the Hartzell Propeller website (www.hartzellprop.com). The following applicable manuals are located in the “Product Support” section under “HPI Ice Protection System Manuals.” Manual 180 – Propeller Ice Protection System Manual Refer to “De-Ice Kits for Non-Counterweighted Compact Propellers” to see illustrated parts lists for 102960-1 and 102960-2 de-ice kits. Manual 181 – Propeller Ice Protection System Component Maintenance Manual Manual 182 – Propeller Electrical De-Ice Boot Removal and Installation Manual.

The propeller de-ice timing cycle is controlled by the same timer originally type-certified on the aircraft. When the PROP HEAT switch is turned ON, the timer provides current to the de-ice boots in a 90-second ON, 90-second OFF cycle and powers all three blades simultaneously. This cycle will continue as long as the PROP HEAT switch is in the ON position. The STC propeller de-ice system utilizes all existing non-rotating hardware such as the slip-ring, brush block assembly, cycle timer, and switches, etc. The system is depicted on Hartzell drawing 102960 (latest revision). Propeller Heat System Troubleshooting Use the troubleshooting routines provided in Piper maintenance manuals for each aircraft model but reference Hartzell drawing 102960 (latest revision) for system installation details and schematics for the propeller rotating system. Brush Module Replacement No Change. New Brush Alignment No Change. Metal Oxide Varistor (MOV) Module Replacement During installation of the STC, Metal Oxide Varistors (MOV) are installed to the brush block assembly for lightning protection. The MOV installation is shown on Hartzell drawing 102960. The MOV module must be replaced in the event of a lightning strike per Hartzell Manual 181. Reference Hartzell drawing 102960 (latest revision) for MOV removal and installation details.

Slip Ring Assembly Alignment No Change. Heater Boots Electrical Check (reference Hartzell drawing 102960 (latest revision)) a) Check the electrical resistance of the element within each de-ice boot. Disconnect the heater lead wires to isolate the individual unit. b) Check for intermittent open circuits by tensioning the heater wire harness slightly while measuring the resistance. Also, press lightly on the heater surface in the area adjacent to the harness. Resistance must not vary. c) The acceptable de-ice boot circuit resistance range is 4.12 - 4.56 ohms. These values only apply to heaters that are not connected to terminal studs. If all three blade heaters are checked in parallel, the acceptable range is 1.37 –1.52 ohms. d) If tests show the blade heater to have an open circuit, to be the wrong resistance or to be visibly damaged beyond repair as outlined in this section, replace the heater.
