            Requirement:  To avoid possible separation of the control wheel control shaft stud from the control shaft tube due to the absence of two roll pins, and subsequent loss of aileron control of the affected control wheel, accomplish the following:

              1. Secure control wheels in the aft position.

2.    Gain access to the control shaft tube assembly (P/N 42939-00) and to stud (P/N 42938-00) connection located just aft of the control wheel stop collar (P/N 40950- 00).

3.    Inspect the forward end of the control shaft tube assembly (P/N 42939-00) to determine if two roll pins (P/N 480732) are installed.

4.    If one or both roll pins are missing, install as required, roll pin Piper P/N 48732 prior to further flight.

            Note: Piper SB No. 651 refers to this subject.

 Compliance: Unless already accomplished, within 5 hours time in service after 18 May 1979. Background:               The subject roll pins may not have been installed at aircraft manufacture.
