Abstract
Designed in the mid 80’s, ATR 42 and ATR 72 regional turboprops were conceived under Damage Tolerance design approach for a Design Service Goal (DSG) of 70 000 flights or equivalent 25 years. Since the oldest aircraft in the fleet are approaching the DSG, under a joined impulse of the ATR Operations and Commercial Directions, activities have been launched to provide ATR operators with an Extended Service Goal (ESG) of 105 000 flights for both ATR 42 and 72 models.
Feedback from the in service world fleet and the results of major fatigue inspections that do not show major fatigue damage are encouraging. The new ESG would provide more flexibility for fleet management as well as an increase in residual value of ATR aircraft.
