Compliance: Required as indicated, unless already accomplished.

To detect cracks in the propeller governor arm and preclude possible loss of propeller control, accomplish the following:

(a) Within the next 25 hours time-in-service after the effective date of this AD, unless already accomplished within the last 25 hours time-in-service, and thereafter at intervals not to exceed 50 hours time-in-service from the last inspection, visually inspect the propeller governor arm with a 5-power magnifier for cracks and breaks in accordance with the following:

(1) For the Model S205 and S208 airplanes, with "Instructions" paragraph (a), steps 1 through 4, of SIAI-Marchetti Service Bulletin No. 205B43A dated September 16, 1977.

(2) For the Model F260 and F260B airplanes, with "Instructions" paragraph (a), steps 1 through 4, of SIAI-Marchetti Service Bulletin No. 260B18A dated September 16, 1977.

(b) If a crack or break is detected as a result of an inspection required by paragraph (a) of this AD, before further flight, replace the propeller governor arm with a serviceable part in accordance with the following:

(1) For the Model S205 and S208 airplanes with "Instructions" paragraph (c), steps 1 through 10, of the SIAI-Marchetti Service Bulletin No. 205B43A dated September 16, 1977.

(2) For the Model F260 and F260B airplanes with "Instructions" paragraph (c), steps 1 through 10, of SIAI-Marchetti Service Bulletin No. 260B18A dated September 16, 1977.

(c) When propeller governor arm, Part No. 260-13-274-01 is installed, the inspections in paragraph (a) of this AD are no longer required.

(d) Any equivalent means of complying with this AD must be approved by Manager, Aircraft Certification Staff, AEU-100, Europe, Africa, and Middle East Office, FAA, c/o American Embassy, Brussels, Belgium.

This AD supersedes AD 77-14-16, Amendment 39-2959.
