# NTSB CHI98LA043: Piper PA-28RT-201T, N8315S, Janesville, WI, November 22, 1997 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: November 22, 1997, 11:00 local (17:00 UTC) - Place: Janesville, WI - Coordinates: 42.679046, -89.009994 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=42.6790&lon=-89.0100&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report January 30, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 10787 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI98LA043 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/10787/pdf - Page: https://openairdocs.org/ntsb/CHI98LA043 ## Probable cause the dual student's failure to obtain the proper touchdown point, and the instructor's failure to provide adequate supervision of the flight. Factors associated with the accident were: inadequate altitude, the student's diverted attention, the snowbank, and the runway light. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Undershoot, landing - flare/touchdown - altitude - inadequate, dual student (contributing factor) - proper touchdown point - not obtained, dual student (cause) - diverted attention, dual student (contributing factor) - supervision - inadequate, pilot in command (cause) - On ground/water encounter with terrain/water, landing - flare/touchdown - terrain condition - snowbank (contributing factor) - On ground/water collision with object, landing - flare/touchdown - object - runway light (contributing factor) ## Analysis While performing a simulated engine failure in the traffic pattern, the flight instructor (CFI) demonstrated the function of the landing gear override to the student, who was also a CFI. While turning final approach, the student lowered the landing gear handle to the down position. When he looked up he noticed the airplane was too low, so he added power. As he was adding power, the right main landing gear contacted a snowbank located 18 inches from the approach end of the runway. The airplane then contacted the edge of the runway and veered to the right where it contacted a runway light. ## Factual narrative On November 22, 1997, at 1100 central standard time (cst), a Piper PA-28RT-201T, N8315S, operated by two certified flight instructors collided with the terrain when it undershot runway 22 at the Rock County Airport, Janesville, Wisconsin. The purpose of the flight was for one flight instructor to check out the other one in this airplane. The airplane was substantially damaged. Neither pilot was injured. Visual meteorological conditions existed at the time of the accident. The flight originated from Grayslake, Illinois, at 0930 cst. The pilot-in-command (PIC) reported that following their departure from Grayslake they performed basic airwork, two ILS approaches, two touch and go's and a full stop landing from a simulated engine out. They then decided to perform one more simulated engine out landing. The PIC stated that once in the traffic pattern he demonstrated the landing gear "override" feature to the pilot in the left seat (student). He reported that on base leg the "override" was disengaged and the landing gear extended. The student placed the landing gear handle in the down position and when he looked up he noticed the altitude of the airplane was low as they were turning onto a "very short final." The PIC stated the student overcorrected as the right wing was low. At the same time the student was adding power to extend the approach the right landing gear contacted a snowbank followed by the edge of the runway. The PIC reported that the snowbank was about 18 inches from the edge of the runway. The right main landing gear collapsed and the airplane slid off the right side and contacted a runway light upon touchdown. ## Aircraft - Registration: [N8315S](https://openairdocs.org/aircraft/N8315S), registered now, S/N 28R-8131044, built 1980 (OpenAirDocs) - Reported make and model: Piper PA-28RT-201T (PA-28RT-20) - Registry model: [Piper PA-28RT-201T](https://openairdocs.org/model/piper-pa-28rt-201t) (registry code 7102817) (OpenAirDocs) - Registry engine: [Continental TSIO-360 series](https://openairdocs.org/engine/continental-tsio-360-series) (registry code 17019, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 28R-8131044 - Airframe hours: 5600 - Engines: Continental TSIO-360-FB 200 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Cardinal Aircraft Service, Inc - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, September 16, 1997, 92 hours before - Departed: C81, GRAYSLAKE, IL - Destination: JVL - Airport: JVL, Rock County, runway 22, 6,701 × 150 ft, asphalt ## Flight crew As NTSB recorded them.
