During a descent, and while passing through approximately 8,000 feet mean sea level, a sudden, violent airframe vibration developed in the twin engine Piper PA-30, and the pilot shut down the right engine. He then noticed a portion of the one of the propeller's tips missing. Metallurgical examination of the blade revealed a fatigue fracture initiating from a dent about 0.2 inch from the leading edge of the blade. The dent measured approximately 0.07 inch wide in the chordwise direction and about 0.03 inch deep and was covered with flat black paint. The propeller log indicated repeated historical occasions whereby the propeller had been dressed and painted. FAA Advisory Circular 43.13-1B/2A, 'Aircraft Inspection, Repair
