ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 82-01-07 SIKORSKY AIRCRAFT: Amendment 39-4293. Applies to Models S-58/S-58T series helicopters certificated in all categories, including Military Type HSS-1, HSS-1F, HSS-1N, HUS-1, HUS-1A, HUS-1AN, HUS-1G, HUS-1Z, H-34A, H-34C, H-34J, CH-34A, CH-34C, HH-34F, HH-34J, SH-34G, SH-34H, SH-34J, UH-34D, UH-34E, UH-34G, UH-34J, VH34C, and VH-34D. To prevent possible fatigue failure of the horizontal hinge pins, replace main rotor head horizontal hinge pins, P/Ns S1610-23020-2, -3, and -4 with a serviceable part prior to the accumulation of 1,000 hours time in service or within 100 hours time in service after the effective date of this AD, whichever occurs later. Thereafter, replace horizontal hinge pin with a serviceable part at intervals not to exceed 1,000 hours time in service. All horizontal hinge pins whose hours time in service cannot be established are to be replaced with a serviceable part within 100 hours time in service from the effective date of this AD. Other actions which provide an equivalent level of safety with this AD may be approved by the Chief, Engineering and Manufacturing Branch, FAA, New England Region. This amendment becomes effective February 1, 1982. FOOTER:
