There has been inflight failure of the propeller attach bolts due to under-torquing of the bolts. In order to preclude the loss of the propeller due to the failure of the bolts, the following is required:

(a) Within the next 10 hours' time in service after the effective date of this AD, unless already accomplished, remove the propeller spinner and remove each propeller attach bolt.

(b) Inspect for cracks in the bolt in the area of the threads using magnetic particle or FAA-approved equivalent inspection method in conjunction with a 5-power or higher magnifying glass. Inspect the grip shank for brinelled surfaces with a 5-power or higher magnifying glass.

(c) If cracks are found or if the bolt is brinelled on the grip shank, replace with new bolts, AN 76-41S. Torque to 300 inch-pounds.

(d) If cracks are not found, reinstall the bolts and torque to 300 inch-pounds.

(e) In lieu of the inspection requirement of (b), new bolts, AN 76-41S, may be installed and torqued to 300 inch-pounds.

(Piper Service Bulletin No. 209, dated April 17, 1962, covers this same subject.)
