# NTSB CHI98LA254: Cessna 172P, N9786L, Abilene, KS, June 19, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 19, 1998, 13:00 local (18:00 UTC) - Place: Abilene, KS - Coordinates: 38.920391, -97.220535 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=38.9204&lon=-97.2205&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report February 15, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 43086 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI98LA254 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/43086/pdf - Page: https://openairdocs.org/ntsb/CHI98LA254 ## Probable cause The student pilot's failure to plan his approach so as to be able to stop the airplane on the runway, and the instructor pilot's delay in taking control of the airplane, so as to correct the student's mistake. A factor contributing to this accident was the ditch. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - in-flight planning/decision - improper, dual student (cause) - remedial action - delayed, pilot in command(cfi) (cause) - On ground/water encounter with terrain/water, landing - roll - airport facilities,runway overrun area - ditch (contributing factor) ## Analysis The dual student was performing a simulated forced landing to the runway. The airplane touched down normally. After rolling down the runway approximately 500 feet, the instructor pilot realized that the airplane was not slowing down. The instructor pilot took control of the airplane and applied heavy braking. Realizing that the airplane was not going to stop on the prepared surface, the instructor pilot guided the airplane onto the hard ground surface overrun. The airplane had almost stopped when 'a hidden ditch appeared.' The instructor pilot said that he did not have time to turn the airplane. The airplane dropped into the ditch. Examination of the airplane revealed no anomalies. ## Factual narrative On June 19, 1998, at 1300 central daylight time (cdt), a Cessna 172P, N9786L, operated by a commercial pilot, sustained substantial damage when while performing a simulated forced landing at Abilene Municipal Airport, Kansas, the airplane landed long, went off the end of the runway, and impacted in a ditch. Visual meteorological conditions prevailed at the time of the accident. The instructional flight was being conducted under 14 CFR Part 91. There were no injuries reported by the instructor pilot, dual student, or passenger on board. The cross-country flight originated at Salina, Kansas, at 0800 cdt. In his written statement, the instructor pilot said that the dual student was performing the maneuver to the runway. The airplane touched down normally. The instructor pilot said that after rolling down the runway 500 feet, he realized that the airplane was not slowing down. The instructor pilot took control of the airplane and applied heavy braking. Realizing that the airplane was not going to stop on the prepared surface, the instructor pilot guided the airplane onto the hard ground surface overrun. The airplane had almost stopped when "a hidden ditch appeared." The instructor pilot said that he did not have time to turn the airplane. The airplane dropped into the ditch. A Federal Aviation Administration (FAA) inspector examined the wreckage at the Abilene Municipal Airport. The airplane's nose wheel was bent aft. The bottom engine cowling was bent upward. The engine mounts and firewall were bent aft and buckled forward. The airplane's left wing forward spar was twisted aft. The left wingtip was crushed inward. Flight control continuity was confirmed. No anomalies were found with the engine, engine controls, or other airplane systems. ## Aircraft - Registration: [N9786L](https://openairdocs.org/aircraft/N9786L), registered now, S/N 17276612, built 1986 (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: 17276612 - Engines: Lycoming O-320-D2J 160 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Civil Air Patrol Inc Natl Hqts - Airworthiness certificate: Standard, Normal - Departed: SLN, SALINA, KS - Destination: K78 - Airport: K78, Abilene Municipal Airport, runway 17, 4,100 × 75 ft, asphalt ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
