Summary
On October 03, 2013, a Venables Zenith CH701 (N143TZ) was involved in an accident near Snohomish, WA. The accident resulted in 1 minor injury. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this accident to be: A jammed rudder control while maneuvering in the pattern for reasons that could not be determined. No follow-up examination was conducted due to a lapse in agency funding and subsequent government shutdown.
The pilot reported that during a test flight the airplane encountered moderate turbulence so he decided to return to the airport for landing. While turning to the crosswind leg in the pattern, the airplane suddenly banked sharply and descended uncontrollably. The pilot was able to regain control about 500 feet above ground level, and managed to turn the airplane to the downwind leg, but he continued to have difficulty maintaining control. The pilot then decided to make an emergency off airport landing to a field. During the landing roll, the airplane collided with obstructions and nosed over. The wings and fuselage were substantially damaged. After the accident, the pilot reported that the loss of aircraft control was due to a jammed rudder for undetermined reasons.
This accident is documented in NTSB report WPR14CA004. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N143TZ.
