Analysis

The helicopter developed a severe vibration while in flt. The pilot executed an emergency landing with no further acft damage. An examination of the acft revealed that the walking beam assembly located between the swash plate and rotor pitch link had failed. Fracturing originated at a corrosion pit on a thread flank. Microscopic examination of the threads revealed that local area of corrosion pitting had occurred where the shot peen balls had been contacting the flanks of the threads.
