## Discrepancy

(CAN) MULTIPLE FAILURES OF INNER TUBES ON VARIOUS AIRCRAFT IN A SHORT PERIOD OF TIME. FAILURE POINT IS IN THE SIDEWALL. PRIMARILY WAS CONFINED TO THE REFERENCED AIRCRAFT ABOVE, BUT HAD A FAILURE OF THE SAME TYPE IN A C152 RECENTLY. REMOVED ALL TUBES FROM STORES AND INSPECTED, FOUND WHAT APPEARS TO BE A MANUFACTURING FLAW IN THE TUBE ITSELF.
