What was found
TEXTRON ALERTED US THAT THE OUTFLOW VALVES ON SOME OF THEIR NEW DELIVERIES WERE PRODUCED BY A VENDOR WITH AN UNCERTIFIED TOOL. THE AFFECTED PARTS WERE ON 2 PLANES THAT WE HAVE TAKEN DELIVERY OF BUT NOT YET ON OUR 135 CERTIFICATE. THESE PARTS WERE ALSO ON 2 OTHER PLANES THAT WERE NEARING DELIVERY DATES. THE 2 PLANES NEARING DELIVERY DATES AS WELL AS ONE THAT WE TOOK DELIVERY OF WERE STILL AT THE FACTORY AND ARE HAVING THE OUTFLOW VALVES CHANGED PRIOR TO US RECEIVING OR USING THEM. THE OTHER PLANE (N295NE) THAT WE DID TAKE DELIVERY OF WENT TO A TEXTRON SERVICE CENTER TO HAVE THE VALVE REPLACED. 2. WHEN AT THE SERVICE CENTER IT WAS DISCOVERED THAT THE EXPECTED SN OF THE VALVE INSTALLED WAS INCORRECT IN TEXTRON'S RECORDS
