Summary:

Two Grob 115E aircraft suffered detachment of a propeller counterweight assembly during initial climb, severely damaging the corresponding propeller blade. Successful forced landings were completed in both cases. Evidence from the second event suggested that the failure was caused by an issue concerning the method of installation of the counterweight assemblies on the affected propeller blades.
