Compliance: Required as indicated, unless already accomplished.

To assure that the fuel shutoff valve will return to the full open position after being shut off, accomplish either Paragraph A or B as follows:

A) Within 50 hours' time in service after the effective date of this AD and thereafter at intervals not to exceed 100 hours' time in service from the date of the last inspection, accomplish the following:

(1) Visually inspect the operation of the fuel shutoff valve by removing the safety wire between the knob and bracket. Then pull the knob out to the full closed position followed by moving the knob forward to the full open position.

(2) Check the fuel shutoff valve arm at the firewall to assure that it has returned to the full open position.

(3) If the inspection discloses that the fuel shutoff valve is operating normally, reinstall .018 mild steel wire between the knob and bracket.

(4) If the inspection discloses that bending of the fuel shutoff valve flexible control wire occurs between the firewall support and the shutoff valve which prevents the fuel shutoff valve from returning to the full open position, prior to further flight make the necessary replacements, adjustments or repairs to assure proper fuel shutoff valve operation, and reinstall .018 mild steel wire between the knob and bracket or alternatively install a heavier fuel shutoff valve control cable P/N S2113-1 and associated parts in accordance with Cessna Service Letter SE70-24, dated September 25, 1970, or later FAA approved revision or any other method approved as an equivalent by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.

C) When the replacement of the heavier fuel shutoff valve control cable P/N S2113-1 and associated parts described in either Paragraphs A(4) or B of this AD have been accomplished, the inspections required by this AD are no longer required.
