Summary
On October 23, 1996, a Piper PA-18 (N3939Z) was involved in an incident near Alliance, NE. All 2 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The instructor-pilot's inadequate supervision by not taking timely action after the student started losing directional control. A factor was the loss of directional control by the student pilot.
On October 23, 1996, at 1630 mountain daylight time, a Piper PA-18, N3939Z, was substantially damaged when the pilot lost control of the airplane during landing. The instructor pilot was unable to take control of the aircraft from the student pilot and prevent the aircraft from a ground loop. The 14 CFR Part 91 flight had departed the Alliance Municipal Airport, Alliance, Nebraska, on a local training flight. Visual meteorological conditions prevailed and no flight plan had been filed.
The instructor pilot reported that the airspeed was a "little fast" during the landing transition. At touchdown the airplane started veering right, but then the student pilot overcorrected and the aircraft veered off the runway to the left. The instructor pilot reported that he came on the controls.
This incident is documented in NTSB report CHI97LA013. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N3939Z.
