## Discrepancy

WHEN COMPLYING WITH ASB 76-53-35, MOD TO CENTER FIREWALL, FOUND NR 1 DRIVE SHAFT SCORED FOR A LENGTH OF 4.50 INCHES.  DEPTH OF SCORE APPROXIMATELY .005 INCH.  REPLACED WITH NEW SHAFT.  SUSPECT THAT SOMEONE PRESSED DOWN ON TOP OF CENTER FIREWALL CAUSING IT TO RUB SHAFT.  ASB WILL RELIEVE CAUSE OF PROBLEM.
