# NTSB DEN05LA005: Cessna 172N, N73764, Casper, WY, October 7, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 7, 2004, 13:35 local (19:35 UTC) - Place: Casper, WY - Coordinates: 42.907775, -106.464164 - Nearby events: https://openairdocs.org/map.md?lat=42.9078&lon=-106.4642&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report January 24, 2005 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 60310 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN05LA005 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/60310/pdf - Page: https://openairdocs.org/ntsb/DEN05LA005 ## Probable cause the student pilot's improper flare resulting in a hard landing. A factor contributing to the accident was the student pilot's improper recovery from the bounced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - flare - improper, pilot in command (cause) - recovery from bounced landing - improper, pilot in command (contributing factor) ## Analysis The solo student pilot was performing her fourth touch-and-go landing when she allowed the airplane to touchdown hard on the runway. The pilot said everything was fine until she got into the flare. She said that she felt she was going to float so she "put in some power." She said she felt she had things under control, so she reduced the throttle to idle. When the airplane touched down, it bounced. The pilot said she released a little back pressure. "The second time it [the airplane] came back to the ground, it bounced hard, and this time I think the propeller hit. It bounced hard 3 or 4 times after that. Back and forth." The pilot said she finally got the airplane stopped. She contacted the tower and received permission to taxi back to the ramp. An inspection of the airplane showed substantial damage to the firewall, and minor damage to the nose gear and propeller. No other anomalies were found. ## Factual narrative On October 7, 2004, at approximately 1335 mountain daylight time, a Cessna 172N, N73764, piloted by a solo student pilot, was substantially damaged when it made a hard landing at the Natrona County International Airport (CPR), Casper, Wyoming. Visual meteorological condition prevailed at the time of the accident. The personal flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan. The pilot reported no injuries. The flight originated at CPR at 1300. The student pilot was performing her fourth touch-and-go landing on runway 21 (10,600 feet by 150 feet, dry asphalt), when she allowed the airplane to touch down hard on the runway. The pilot said everything was fine until she got into the flare. She said that she felt she was going to float so she "put in some power." She said she felt she had things under control, so she reduced the throttle to idle. When the airplane touched down, it bounced. The pilot said she released a little back pressure. "The second time it [the airplane] came back to the ground, it bounced hard, and this time I think the propeller hit. It bounced hard 3 or 4 times after that. Back and forth." The pilot said she finally got the airplane stopped. She contacted the tower and received permission to taxi back to the ramp. An inspection of the airplane revealed that the airplane's nose gear was bent aft and the firewall was buckled in several places. One propeller blade was bent aft at the tip. The student pilot's instructor reported the pilot was an average to medium skilled student. The student pilot had soloed two times previously. ## Aircraft - Registration: [N73764](https://openairdocs.org/aircraft/N73764), registered now, S/N 17267661 (OpenAirDocs) - Reported make and model: Cessna 172N - Registry model: [Cessna 172N](https://openairdocs.org/model/cessna-172n) (registry code 2072434) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17267661 - Airframe hours: 7693.3 - Engines: Lycoming O-320-H2AD 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Wyoming Air Corporation, doing business as Wyoming Air - Registered owner: Beecher J.
