This document is an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority of Australia concerning the Piper PA-46 Malibu series aeroplanes. It specifically addresses models PA-46-310P and PA-46-350P, mandating actions to ensure the proper functioning of the Turbine Inlet Temperature (TIT) gauge and associated probe. The directive outlines inspection, calibration, and maintenance requirements to prevent unsafe conditions that could lead to engine damage or failure. It includes compliance timelines and specific procedures to be followed by operators and maintenance personnel. The document serves as a critical reference for maintaining airworthiness and operational safety of the affected aircraft models.
- Models affected: PA-46-310P and PA-46-350P.
- Immediate inspection and calibration of the TIT gauge required within 100 hours TIS.
- Revised emergency procedures must be added to the AFM/POH.
- Probe replacement is mandated after 250 hours TIS or within 100 hours TIS after the directive's effective date.
- Compliance is required as of the effective date: 10 August 2000.

Applicability
The Airworthiness Directive applies to all serial numbers of the Piper PA-46-310P and PA-46-350P aeroplanes equipped with a Lewis or Transicoil Turbine Inlet Temperature Gauge and associated probe.
Requirements for PA-46-310P
Operators must clean and inspect the TIT gauge and probe, calibrate the system, and repair or replace any failed parts. Revised emergency procedures must be incorporated into the AFM/POH.
Requirements for PA-46-350P
Similar to the PA-46-310P, operators must clean and inspect the TIT gauge and probe, calibrate the system, and replace the probe with a new part number if necessary. Emergency procedures must also be updated in the AFM/POH.
Compliance Timeline
The compliance for various requirements ranges from immediate actions to be taken within the next 100 hours of service, to specific intervals for probe replacement and inspection.
Background
The directive aims to detect and correct improperly calibrated TIT indicators or defective probes, which could lead to engine operation issues and potential loss of control of the aircraft.
Safety notes
- Improperly calibrated TIT indicators can lead to engine damage or failure.
- Defective TIT probes may result in loss of control of the aeroplane.

COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES Piper PA-46 (Malibu) Series Aeroplanes AIRWORTHINESS DIRECTIVE For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section. AD/PA-46/29 Turbine Inlet Temperature Gauge 8/2000 Applicability: Models PA-46-310P and PA-46-350P aeroplanes, all serial numbers, that are equipped with a Lewis or Transicoil Turbine Inlet Temperature (TIT) Gauge and associated probe installed. Note 1: Relief from this Directive is available only if the gauge and probe have been replaced through a Supplemental Type Certificate or a modification approved pursuant to Civil Aviation Regulation (1988) 35 and not if a second TIT gauge was installed while retaining the Lewis or Transicoil gauge and probe. Requirement: For Model PA-46-310P aeroplanes: 1. Perform the following on the TIT System: a. Clean and inspect the TIT gauge and probe in accordance with procedures in PA-46-310P/350P Maintenance Manual, Chapter 77-20-00 (section A.(1)(d), pages 1 and 2). b. Calibrate the system in accordance with procedures in PA-46-310P/350P Maintenance Manual, Chapter 77-20-00 (pages 3 and 4). 2. Repair or replace any failed parts detected during the Requirement 1 inspection or calibration with serviceable parts as listed in Table 1. 3. Incorporate revised emergency procedures in Section 3 of the Aeroplane Flight Manual/Pilot’s Operating Handbook (AFM/POH). This may be accomplished by inserting the following statement in the AFM/POH or by incorporating the appropriate revision, listed in Table 2, in the AFM/POH. (i) If the turbine inlet temperature indication fails during takeoff, climb, descent, or landing, maintain FULL RICH mixture to assure adequate fuel flow for engine cooling. (ii) If the turbine inlet temperature indication fails after cruise power has been set, maintain cruise power setting and lean to 6 gallons per hour (GPH) fuel flow above that specified in the Power Setting Table in Section 5 of the AFM/POH. Continually monitor engine cylinder head and oil temperatures to avoid exceeding temperature limits. COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES 4. Lewis or Transicoil TIT gauges or probes may not be installed without assuring that they are airworthy and calibrated. This may be determined by using the procedures referenced in Requirement 1. For Model PA-46-350P aeroplanes: 5. Perform the following on the TIT System: a. Clean and inspect the TIT gauge and probe in accordance with the following procedures: (i) For serial numbers 4622001 through 4622200 and 4636001 through 4636020, utilise the PA-46-350P Maintenance Manual, Chapter 77-20-00 (section 1.C, page 1). (ii) For all serial numbers beginning with 4636021, utilise the PA-46-350P Maintenance Manual, Chapter 77-20-00 (section 1.C, page 1). b. Calibrate the system in accordance with the following procedures: (i) For serial numbers 4622001 through 4622200 and 4636001 through 4636020, utilise the PA-46-350P Maintenance Manual, Chapter 77-20-00 (section 1.I, pages 4 through 7). (ii) For all serial numbers beginning with 4636021, calibration is not required. 6. Repair or replace any failed parts detected during the Requirement 5 inspection or calibration with serviceable parts as listed in Table 1. 7. Replace the probe with a new part number 481-389 or 481-392 probe. 8. Incorporate revised emergency procedures in Section 3 of the AFM/POH. This may be accomplished by inserting the following statement in the AFM/POH or by incorporating the appropriate revision, listed in Table 2, in the AFM/POH. (i) If the turbine inlet temperature indication fails during takeoff, climb, descent or landing, set power per the POH Section 5 Power Setting Table and then lean to the approximate POH Power Setting Table fuel flow plus 4 GPH. (ii) If the turbine inlet temperature indication fails after cruise power has been set, maintain the power setting and increase indicated fuel flow by 1 GPH. Continually monitor engine cylinder head and oil temperatures to avoid exceeding temperature limits. COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES 9. Lewis or Transicoil TIT gauges or probes may not be installed without assuring that they are airworthy and calibrated. This may be determined by using the procedures referenced in Requirement 5. Table 1 Equipment Name and Manufacturer Part Number Lewis Turbine Inlet Temperature Analog Indicator 471-008. This is the only indicator that has a zero adjustment screw. Lewis Turbine Inlet Temperature Digital Indicator 548-811. Since this indicator does not have a zero adjustment screw, you must return it to the factory for adjustment or replacement.
