# NTSB CHI07CA128: Cessna 172P, N97224, West Chicago, IL, May 1, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: May 1, 2007, 16:50 local (21:50 UTC) - Place: West Chicago, IL - Coordinates: 41.907775, -88.248611 - Nearby events: https://openairdocs.org/map.md?lat=41.9078&lon=-88.2486&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report June 27, 2007 - Report: Approved by Office Director - Parties: Federal Aviation Administration, DuPage FSDO - NTSB case key (mKey): 65752 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI07CA128 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65752/pdf - Page: https://openairdocs.org/ntsb/CHI07CA128 ## Probable cause The instructor's inadequate remedial action following the student pilot's loss of control during the crosswind landing and the instructor's failure to compensate for the wind conditions. Contributing factors were, the crosswind, the gusting wind conditions and the ditch. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - flare/touchdown - remedial action - inadequate, pilot in command(cfi) (cause) - compensation for wind conditions - inadequate, pilot in command(cfi) (contributing factor) - weather condition - crosswind (contributing factor) - weather condition - gusts (contributing factor) - On ground/water encounter with terrain/water, landing - terrain condition - ditch (contributing factor) ## Analysis The airplane impacted a ditch following an uncontrolled exit from the runway surface (runway 33, 3,401 feet long, 100 foot wide, dry concrete). The instructor reported that after touchdown, the power was increased but the airplane yawed into the left crosswind. The airplane then exited the runway into the grass adjacent to the runway. The instructor stated that the main gear dragged in the grass and the nose gear dug into the ground. The airplane then pivoted to the right and the left wingtip impacted and dragged through the grass. The reported wind conditions about the time of the accident were from 280 magnetic degrees at 13 knots, gusting to 21 knots. Inspection of the airplane did not reveal any flight control or mechanical malfunction that would have prevented normal operation. ## Factual narrative The airplane impacted a ditch following an uncontrolled exit from the runway surface. The student pilot and certified flight instructor were returning from a local area training flight. During the landing to runway 33 (3,401 feet by 100 feet, asphalt), the airplane lifted off after touchdown. The instructor reported that power was increased but the airplane yawed into the left crosswind. The airplane then exited the runway into the grass adjacent to the runway. The instructor stated the main gear dragged in the grass and the nose gear dug into the ground. The airplane then pivoted to the right and the left wingtip impacted and dragged through the grass. The reported wind conditions about the time of the accident were from 280 magnetic degrees at 13 knots, gusting to 21 knots. Inspection of the airplane did not reveal any flight control or mechanical malfunction that would have prevented normal operation. ## Aircraft - Registration: [N97224](https://openairdocs.org/deregistered/N97224-2018-01-17), registration cancelled 2018-01-17, S/N 17276165, built 1984 (OpenAirDocs) - Reported make and model: Cessna 172P - Registry model: [Cessna 172P](https://openairdocs.org/model/cessna-172p) (registry code 2072436) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17276165 - Airframe hours: 16717 - Engines: Lycoming O-320 160 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: American Flyers - Registered owner: American Flyers of New York - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: 100 hour, March 1, 2007 - Departed: DPA, West Chicago, IL - Airport: DPA, DuPage Airport, runway 33, 3,401 × 100 ft, concrete ## Flight crew As NTSB recorded them.
