## Discrepancy

RT CABIN ANTI-VIBRATOR TUNING HAMMER.  SUPPORT FITTINGS CRACKING IN RADIUS, BOTH FORE AND AFT FITTINGS CRACKING AT SAME TIME.  THIS CAUSES NOTICEABLE INCREASE IN CABIN VIBRATION LEVELS.  FITTINGS SHOULD BE STRONGER AND MACHINING OF THE PARTS SHOULD INCLUDE A MUCH GREATER RADIUS IN THE EFFECTED AREA OF CRACK OCCURRENCE.
