Like I say, the manufacturer, (and the operator) have the last say. No conflicts there!!
The regulators sign off on anything approved by the Manufacturer, the Line has no vested interest in the other?? You are a trifle naive, Sir.
The AD was relaxed on the 900 in August, two months prior to the Burst. Based on what information?? Inspections performed by the Manufacturer's agents!!
Does one have a copy of the contract?? Thought not.
