# NTSB CHI01LA205: Cessna 172S, N795SP, Lake in the Hil, IL, July 11, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 11, 2001, 18:30 local (23:30 UTC) - Place: Lake in the Hil, IL - Coordinates: 42.16082, -88.299049 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=42.1608&lon=-88.2990&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report May 21, 2002 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 53270 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI01LA205 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/53270/pdf - Page: https://openairdocs.org/ntsb/CHI01LA205 ## Probable cause The student pilot misjudging the flare during that landing. Factors were the wrong runway selected by the student pilot, the tailwinds encountered during that landing and the flight instructor's inadequate supervision during that landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare - misjudged, pilot in command (cause) - weather condition - tailwind (contributing factor) - wrong runway - selected, pilot in command (contributing factor) - supervision - inadequate, pilot in command(cfi) (contributing factor) ## Analysis The airplane sustained substantial damage during a hard landing. The pilot was uninjured during the solo instructional flight. The student pilot stated, "As the plane touched down on runway it seemed to land on main wheels but harder that normal and bounced upward at this time[.] I added a little throttle to level plane back for proper landing and then pulled throttle back to idle as plane had smoothed out to flair however the plane touched the runway even a little harder than first bounced and I felt the plane was not safe to land at this time and did another go around. I did not feel or see the prop or tail of plane touch runway surface[.] As I did the proper procedure for go around the plane seemed to fly proper. I then was instructed to use runway 08 for landing because of other traffic on route to 08 on final. I followed this plane in after it had cleared the runway and landed the plane with more of a normal landing. At this time a instructor greeted me upon securing the plane and damage was noted with prop being bent on both ends." The student pilot and instructor pilot stated that there were no "mechanical malfunction failure" with the airplane during the flight. The wind in the area was 080 degrees at 10 knots. ## Factual narrative On July 11, 2001, about 1830 central daylight time, a Cessna 172S, N795SP, piloted by a student pilot, sustained substantial damage during a hard landing at Lake in the Hills Airport (3CK), near Lake in the Hills, Illinois. The solo instructional flight was operating under 14 CFR Part 91. Visual meteorological conditions prevailed at the time of the accident. No flight plan was on file. The pilot was uninjured. The local flight departed from 3CK at time unknown and was performing a landing at the time of the accident. The student pilot stated: I proceeded in normal route for pattern and attempted my second landing upon final I felt the plane was in proper requirements of landing aprox 65-70 Kts with full flaps and aprox. 900 feet at approaching runway 26. I attempted to put the plane on runway for normal landing. [T]he plane seemed to float above the runway longer than normal. As the plane touched down on runway it seemed to land on main wheels but harder that normal and bounced upward at this time[.] I added a little throttle to level plane back for proper landing and then pulled throttle back to idle as plane had smoothed out to flair however the plane touched the runway even a little harder than first bounced and I felt the plane was not safe to land at this time and did another go around. I did not feel or see the prop or tail of plane touch runway surface[.] As I did the proper procedure for go around the plane seemed to fly proper. I then was instructed to use runway 08 for landing because of other traffic on route to 08 on final. I followed this plane in after it had cleared the runway and landed the plane with more of a normal landing. At this time a instructor greeted me upon securing the plane and damage was noted with prop being bent on both ends. The student pilot and instructor pilot stated that there were no "mechanical malfunction failure" with the airplane during the flight.
