SUMMARY - 1.1. Background - Application of MWO 55-1520-240-50-43 replaced three piece engine drive shaft, P/N 145D3500-15, with a one piece engine drive shaft, P/N 145D3504-2. At that time an interim retirement life of 2000 hours was established. The interim retirement life was to remain in effect until fatigue testing was conducted and verified. Based on fatigue test results, the retirement life of P/N 145D3504-2 can safely be increased to 6000 hours for all but 49 of these shafts. These 49 shafts were flown on certain aircraft during a specific time frame which cannot allow their retirement lives to be increased. These 49 specific serial numbered shafts will remain at the 2000 hour retirement life. 1.2. Message Purpose - Increase the retirement life of all but 49 specific serial numbered engine drive shafts from 2000 hours to 6000 hours. 2. END ITEMS AFFECTED - All H-47 series aircraft. 3.
