Airworthiness Directive 2011-7569
recurringAirworthiness Directives; Piper Aircraft, Inc. (Type Certificate Previously Held by The New Piper Aircraft, Inc.) Models PA-46-310P, PA-46-350P, and PA-46R-350T Airplanes
What this AD requires
We are superseding an existing airworthiness directive (AD) that applies to certain Piper Aircraft, Inc. Models PA-46-310P and PA- 46-350P airplanes that are equipped with a Lewis or Transicoil turbine inlet temperature (T.I.T.) gauge and associated probe. That AD currently requires cleaning, inspecting, and calibrating the T.I.T. system; replacing any T.I.T. system that fails the calibration test; repetitively replacing the T.I.T. probe on certain airplanes; and inserting a copy of the AD into the pilot's operating handbook (POH) for certain airplanes. This new AD retains the actions required by the previous AD (AD 99-15-04 R1), adds certain Model PA-46R-350T airplanes to the Applicability section, expands the applicability to include other T.I.T. systems, and incorporates new service information. This AD was prompted by the manufacturer revising related service information and adding an airplane model to the list of affected airplanes. We are issuing this AD to prevent improper engine operation caused by improperly calibrated T.I.T. indicators or defective T.I.T. probes, which could result in engine damage/failure with consequent loss of control of the airplane.
Which aircraft AD 2011-7569 applies to
Applies only to airplanes equipped with the Lewis or Transicoil turbine inlet temperature (T.I.T.) gauge/probe system identified in Table 3 of the AD (indicator P/N 471-008 or 548-811; probe P/N 471-009, 481-387, 481-389, 481-392, or 686-216, depending on serial number). Relief is available only if the gauge and probe are replaced via STC, not if a second T.I.T. gauge was added while retaining the original gauge/probe.
Whether AD 2011-7569 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
Supersession
Supersedes AD 99-15-04.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
