SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:  
69-07-02 PILATUS: Amdt. 39-743. Applies to Model PC-6 Airplanes Serial Nos. 1 through 701, 2001 through 2018, 2023, 2025 through 2029, 2040 and 2041.

Compliance required as indicated unless already accomplished.

To prevent structural damages to the aileron mass balance unit P/N 6106.11, due to internal corrosion, accomplish the following:

(a) Within the next 10 hours' time in service after the effective date of this AD, and thereafter at intervals not to exceed 10 hours' time in service from the last inspection, inspect the external surface of the mass balance support arms for evidence of corrosion (indicated by blistering of paint or slight discoloration).

(b) If evidence of corrosion is detected during the inspection prescribed in paragraph (a), before further flight, replace the aileron mass balance unit P/N 6106.11 with a modified aileron mass balance unit P/N 6106.11 (which is identified by a 1/2-inch diameter yellow colored marking), or with a new aileron mass balance unit P/N 111.45.08.001, in accordance with Pilatus Service Bulletin No. 89, dated November 1968 or later Swiss Federal Air Office approved revision or an FAA approved equivalent.

(c) The repetitive inspections required by paragraph (a) may be discontinued after the modified or new aileron mass balance unit has been installed.

This amendment becomes effective April 1, 1969.
