### E ng ine- Propeller S haft - Inspection 

### I Replace ment
Solo Kleinmotoren GmbH Model2350 C engines , all serial numbers , if a Part Number (PIN) 20 3 1 211 propeller shaft is installed. The affected engines are only installed on DG-Fiugzeugbau Model DG-1 OOOT powered sailplanes
. Reason : Two reports have been received of a broken PIN 20 31 211 propelle r shaft on a Solo 2350 C engine. The results of the investigation showed that the failures were due to a material defect, most likely caused by a manufacturing error.

Effective Date: This condition, if not detected and corrected, could lead to fail u re of the shaft and detachment of the propeller from the aeroplane, which, depending on the flight conditions, could result in reduced control of the aeroplan e, or injury to person s on the ground. For the reasons described above , this AD requires a one-time inspection (magnetic particle or dye penetrant) of the affected propeller shafts to detect cracks and, depending on find i ngs, replacement of the propeller pulley assembly (module) with a serviceable module. 09 October 2012
