GFA AD 668 Cancelled 14.09.2018.pdf
IN-FLIGHT LOSS OF PROPELLER AND PULLEY WHEEL FROM THE ENGINE OF A GROB G103 C TWIN III POWERED SAILPLANE
CANCELLED Refer EASA AD 2010-0107
Grob Aircraft AG suspects that the possible reasons for this loss can be due to an incorrect propeller track (the play at the propeller tip) and/or to a damaged propeller nut securing plate. These conditions, if not corrected, could also result in loosening of parts and, consequently could result in damage to the sailplane and possible injury to persons on the ground. For the reasons stated above, this AD requires to inspect the propeller assembly attachment, to verify that the propeller track is within the allowable tolerances and, depending on findings, to accomplish the relevant corrective actions.
