## Discrepancy

DURING TAKEOFF FROM A GRASS STRIP AS THE AIRCRAFT APPROACHED 30 TO 40 KNOTS, BOTH NOSE WHEELS INSTALLED ON THE FLOATS FAILED, CAUSING THE AIRCRAFT TO FLIP ON TO ITS BACK.  UPON EXAMINATION OF THE FLOAT NOSE WHEEL STRUTS THE FAILURE OCCURRED AT THE WELD JOINT OF BOTH LT AND RT WHEEL STRUTS.  IT APPEARS THAT THE WELDS DID NOT HAVE ADEQUATE PENETRATION.  INVESTIGATION OF MFG IN PROCESS.  (K)
