What was found
DURING TAXI, NOSE TIRE WENT FLAT. A COUPLE OF YEARS AGO, HAD A PROBLEM WITH TIRES/TUBES GOING FLAT ON TAXI; AS WELL AS, IN THE HANGAR. SWITCHED TIRE AND TUBE MFG AND THIS ALLEVIATED THE PROBLEM FOR A WHILE. OUT NORMAL PRACTICE IS TO REPLACE BOTH TIRE AND TUBE AND WE HAVE NOT CHANGED THAT PROCESS. RECENTLY, WE HAVE NOTICED AN INCREASE IN THE FLAT TIRES/TUBES AND IAW OUR SAFETY OFFICE THEY HAVE REQUESTED THAT WE SUBMIT SDR FORMS.
