NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The private pilot stated that, during the landing flare at the conclusion of a local flight, the airplane's nose "shot up drastically." The pilot "gently" pressed forward on the controls to lower the nose, and the airplane pitched down and impacted the runway. Examination of the airplane revealed that a bolt that attached the left elevator to the control system was not installed, and the FAA inspector reported that the bolt was found undamaged inside the elevator tip. According to the pilot, maintenance personnel had recently removed the left elevator, and it is likely that they failed to properly secure the bolt when they reinstalled the elevator.


The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • Maintenance personnel's improper installation of the elevator bolt, which resulted in a loss of elevator control during landing.
