The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct an 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.

Propellers - Variable Pitch - Hartzell
AD/PHZL/79 Amdt 2  Propeller Vibration Placard  12/2014

Applicability:  This AD applies to Hartzell ( )HC-C2YK-( )( )( )/( )( )7666A-( ) propellers installed on undampered 200 horsepower Lycoming IO-360 engines.
                Note 1:  These engines can be fitted to but are not limited to Mooney M20E and M20F, Piper PA-28R-200, and Pitts S-1T and S-2A aeroplanes.

                Note 2:  Engine models of this series incorporate no crankshaft dampers unless the third section of the model designation exhibits a numerical digit in its fourth position, i.e. IO-360-A1B6.  The digit "6" in the fourth position, indicates the incorporation of one 6.3 order and one 8th order counterweights.
Requirement:    For Normal Category aeroplanes:

                   1. Unless previously accomplished, remove any vibration placard that does not have the following statement and replace it with one that does:

                   "Avoid continuous operation
                   Between 2000 and 2350 rpm"

                   2. Unless previously accomplished, re-mark the tachometer face or bezel with a red arc for the restricted engine speed range, between 2000 and 2350 rpm.

                   3. Include a copy of this AD with the aeroplane flight manual, if an aeroplane flight manual is carried.

                For Utility and Aerobatic Category aeroplanes:

                   1. Unless previously accomplished, remove any vibration placard that does not have the following statement and replace it with one that does:

                   "Avoid continuous operation
                   Between 2000 and 2350 rpm.
                   Above 2600 rpm in aerobatic flight".

                   2. Unless previously accomplished re-mark the tachometer face or bezel with a red arc for the restricted engine speed range, between 2000 and 2350 rpm, and between 2600 and 2700 rpm (red line).

                3. Include a copy of this AD with the aeroplane flight manual, if an aeroplane flight manual is carried.
             Note 3:  FAA AD 2007-26-09 Amdt 39-15311, paragraph (k) refers.
Compliance:  Unless previously accomplished, the required actions for Normal Category aeroplanes and Utility and Aerobatic Category aeroplanes must be taken from the effective date of this AD.
