Narrative:A Globe GC1B lost a propeller blade in-flight while maneuvering in the number two position of a formation of three airplanes, a propeller blade separated from the propeller hub assembly. The second propeller blade, along with the hub assembly, subsequently separated from the engine crankshaft. Examination of the recovered propeller hub fracture faces disclosed fatigue cracking. The fatigue fracture propagated until it intersected the outside hub surface. According to McCauley Propeller the fatigue fracture reduced the propeller hub load carrying capacity until it was no longer a sufficient cross section to carry the centrifugal load of the propeller.
Probable Cause: Fatigue cracking of the propeller hub that resulted in the in-flight separation of a propeller blade.
