to do the inspections.

                  b. If the torque of any one bolt is found to be less than 90 ft-lbs, remove and inspect the propeller, and resurface the flanges as necessary.

                  Use paragraphs 3.B. through 3.B.(5) of the Accomplishment Instructions of Hartzell Propeller Inc. SB No. HC-SB-61-275, to do the inspection and resurfacing.  Replace all mounting bolts with new mounting bolts.

                4. If the propeller and engine mounting flanges have been resurfaced, using either Hartzell Propeller Inc. Alert SB No. A203A, or SB No. HC-SB-61-275, and a fretting disk was installed, then:

                  a. Remove the propeller, and inspect the propeller and engine mounting flanges.  Resurface the flanges if necessary and replace the fretting disk.

                  b. Thereafter, remove the propeller and repeat the flange inspections and replace the fretting disk.

                Use paragraphs 3.B. through 3.B.(5) of the Accomplishment Instructions of Hartzell Propeller Inc. SB No. HC-SB-61-275, to do the inspection and resurfacing.  Replace all mounting bolts with new mounting bolts.

                5. Inspect the propeller and engine mounting flanges and resurface the flanges if necessary.

                Use paragraphs 3.B. through 3.B.(5) of the Accomplishment Instructions of Hartzell Propeller Inc. SB No. HC-SB-61-275, to do the inspection and resurfacing.  Replace all mounting bolts with new mounting bolts.

Compliance:     1. For propellers having 3,000 or more flight hours (FH) time-since-new (TSN) on the effective date of this AD:

                  - Before further flight after the effective date of this AD, if the bolt torque inspection has never been done, and thereafter at intervals not to exceed 120 FH.

                  - For bolts last inspected using AD/SD3-30/23 or AD/SD3-60/41:  Within 120 FH from the last inspection or from the effective date of this AD, whichever occurs first, unless already done, and thereafter at intervals not to exceed 120 FH.

                For propellers having fewer than 3,000 FH TSN on the effective date of this AD - upon reaching 3,000 FH TSN, and thereafter at intervals not to exceed 120 FH.

                2. Before further flight after the effective date of this AD.

                  3. a. Within 120 FH after reaching 1,500 FH from the time the flanges were last resurfaced, and thereafter at intervals not to exceed 120 FH.

                  b. Before further flight after the effective date of this AD.

                  4. a. Within 120 FH after reaching 1,500 FH from the time the flanges were last resurfaced.

                  b. At intervals not to exceed 1,500 FH.

                5. Whenever the propeller is removed from the engine and whenever a propeller is removed from an engine to be installed on an aeroplane model not listed
