Aircraft Accident Investigation Report

34 The engine internal timing was found to be out of time by one tooth between the crankshaft and camshaft as seen in Figure 35. This caused the timing mark on the starter ring gear support assembly to be about 7 teeth out of alignment with alignment dot (hole) on the starter bendix gear housing as seen in Figure 36; this translates to approximately 16.8 degrees out of time.
