Fatigue life time prediction of PoAF Epsilon TB-30 aircraft - Implementation of automatic crack growth based on 3D finite element method

At the end of the article the authors concluded that the TVF of Epsilon aircraft is 24,500 flight hours (FH), the first inspection should be done when the aircraft reaches 10,000 FH and the flowing inspections should be done with a periodicity of 3000 FH until the crack reaches a critical dimension of 1.5 mm.
