## Discrepancy

PIPER ISSUED NOSE GEAR MODIFICATION KIT NR 764-378V HAS TO CHANGE THE COTTER PIN IN THE LOWER NOSE GEAR LINK ASSY TO A LONGER SIZE.  THE 424-051 COTTER PIN IS TOO SMALL AND HAS CAUSED A NOSE GEAR FAILURE DUE TO THE COTTER PIN SHEARING OFF AND THE NUT BACKING OFF THE DOWNLOCK ASSY.  KIT WAS INSTALLED APPROXIMATELY 200 HOURS EARLIER.
