ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 70-18-05 PIPER: Amendment 39-1076. Applies to the following models: PA-28-140, /- 150, /-160, /-180, /-235, and PA-32-260, /-300. The following are affected serial numbers: PA- 28-140, 28-20001 through 28-22354; PA-28-150, /-160, /-180, 28-1 through 28-3782; PA-28-235, 28-10001 through 28-10806; PA-32-260, 32-1 through 32-853; PA-32-300, 32-40001 through 32-40057. Compliance required within the next 50 hours' time in service after the effective date of this AD, unless already accomplished. To preclude the possibility of failure of the main landing gear torque link bolts accomplish the following: The bolt and lock nut attaching the upper torque link to the main landing gear housing assembly must be replaced with an AN5-23 bolt, AN310-C5 nut, and AN381-2-8 cotter pin. The bolt and lock nut attaching the lower torque link to the main landing gear housing assembly must be replaced with an AN5-22 bolt, AN310-C5 nut, and AN381-2-8 cotter pin. The bolt or grease bolt and lock nut attaching the torque links at the scissor joint must be replaced with a grease bolt, Piper part number 65788-00, (hole in threaded end of bolt for cotter pin safety), AN944-101 lubricator fitting, AN 310-C5 nut, AN381-2-8 cotter pin, and appropriate washers. Piper Kit 757-123 contains the necessary hardware and instructions to accomplish this modification. Equivalent replacement parts approved by the Chief, Engineering and Manufacturing Branch, FAA Southern Region, may be used.
