Narrative:During a banner-pick up maneuver, the pilot “heard and felt a pop from the elevator cable.” The airplane leveled off with the flight control stick in the full-aft position, and the elevator was in the neutral position. The airplane continued in an uncontrollable slight descent into a rough field where the airplane impacted with the ground. Wreckage examination revealed the cable for the elevator's, pitch-up control, located at the lower end of the control stick through the attaching thimble, had slipped through the cable oval sleeve swage. Examination by the NTSB Material Laboratory of the swage revealed the incorrect grooves on the hand tool was used to crimp the swage. The operator was not utilizing a “go–no go” gauge to insure proper crimping of the oval sleeve swage. Several airplanes in the operator’s 27 airplane fleet had flight control cable fabricated and replaced by their maintenance personnel. The operator grounded its fleet and conducted an inspection of flight control cable assemblies. A total of 36 flight control cable swages and 41 flight control cables were required to be replaced.
Probable Cause: The loss of pitch control due to slippage of the elevator control cable resulting from the maintenance personnel’s improper installation and inspection of the cable.
