Compliance required as indicated.

To detect cracks in the elevator torque tube and supporting rings, accomplish the following:

(a) Within the next 10 hours' time in service after the effective date of this AD, unless already accomplished, visually inspect the inside area of the elevator torque tube P/N 27-223002-3 between Elevator Stations 11.811 (inboard end rib) and 15.748 (next rib outboard) and the elevator end (inboard) rib and internal elevator structure adjacent to the elevator torque tube for cracks using a mirror and light or an equivalent inspection approved by an FAA maintenance inspector. If a crack is found, comply with (c) before further flight.

(b) Within the next 75 hours' time in service after the effective date of this AD, unless already accomplished, inspect the elevator torque tube P/N 27-223002-3 between Elevator Stations 11.811 and 15.748 and the torque tube supporting rings P/N 27-223006-9 (inboard end rib) and P/N 27-223006-3 (next rib outboard) for cracks using X-ray or dye-penetrant with a glass of at least 10-power or an equivalent inspection approved by an FAA maintenance inspector. If a crack is found comply with (c) before further flight.

(c) Replace any part found cracked with a part of the same part number that has been inspected for cracks in accordance with (b) or with an equivalent part approved by the Chief, Engineering and Manufacturing Branch, FAA Eastern Region.

(d) Upon request of the operator an FAA maintenance inspector may, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Eastern Region, increase the initial compliance times specified in this AD by not more than 5 hours' time in service if the request contains substantiating data to justify the increase for that operator.
