According to a Reuters report, Israel Aerospace Industries (IAI) has advised customers not to fly some Boeing 737 freighters converted by IAI pending a review by Israel's aviation authority, Civil Aviation Authority of Israel (CAAI).
IAI said it had detected an "apparent irregularity" in the production process of a rigid barrier installed in some of the conversions, 47 of which it has delivered.
IAI did not confirm to the news service how many companies operate these planes.
