Background:     Cracks were detected in some structural components during ERJ 190 aircraft full scale fatigue testing.  Analysis of the cracking has resulted in modifications to the aircraft Airworthiness Limitation Items to include new inspections tasks or modification of existing ones, and respective thresholds and intervals.  Undetected fatigue cracking in the affected areas could adversely affect the structural integrity of the aircraft.
