## Discrepancy

THIS BROKEN TAIL WHEEL CENTER SPRING IS PART OF A FIELD APPROVAL FOR INSTALLING THE  SCOUT TAIL WHEEL SPRINGS ONTO AN 7ECA. THE REASON BEING THAT THE SCOUT TAIL WHEEL SPRINGS ARE STIFFER AND HANDLE THE STRESSES OF THE FLIGHT SCHOOL TRAINING ENVIRONMENT BETTER. IT WAS FOUND DURING THE AIRCRAFTS SECOND 100 HRS INSP AT A TOTAL TIME OF 192.6 HRS ON ACFT. THERE WAS A FIELD APPROVAL MODIFICATION FOR THE HEAVIER SCOUT SPRINGS THAT WAS INSTALLED ONTO THE AIRCRAFT AT A TOTAL TIME OF 21.8 HOURS. THE BROKEN SPRING WAS FOUND A A TOTAL TIME OF 170.8 HRS TOTAL TIME ON THE SPRINGS AFTER FIELD APPROVAL. IT APPEARS TO HAVE BROKEN FOR A WHILE DUE TO AMOUNT OF RUST THAT WAS FOUND ON THE FRACTURED CROSS SECTION AREA.
