Analysis

Acft experienced a partial eng failure in flight. During the forced landing, the nose gear dug into terrain and the acft flipped over. Investigation revealed that the no. 3 cyl barrel was cracked about 90% around the circumference. Metallurgical examination revealed that crack had initiated in fatigue due to improper machining of the barrel to cooling fin radius during manufacture. In addition, corrosion pitting in the area of the fatigue origin aggravated the original defect.
