TEL AVIV, Israel — The U.S. Army has joined the Israeli Air Force in a sweeping investigation of AH-64 Apache helicopters following Israel’s discovery earlier this month of a crack in the rear rotor blade of one of its aircraft, defense and industry sources here say.
In interviews here Monday, a defense source noted that prime contractor Boeing is working with the Israeli Air Force and the U.S. Army to determine the cause of the crack. So far, he said, only one Israeli Air Force platform appears to be impacted by the potential problem surrounding the safety of flights.
Since the investigation began here June 13, Israel’s Apache attack force has been grounded and will remain so pending conclusions of ongoing inspections, according to the Israeli military.
Boeing and the U.S. Army did not respond to requests for comment by press time.
The Israeli Air Force’s Depot 122 at Tel Nof Air Base is leading the ongoing inspection.
