# NTSB LAX97LA251: Cessna 150M, N8168U, Chico, CA, July 7, 1997 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 7, 1997, 12:05 local (19:05 UTC) - Place: Chico, CA - Coordinates: 39.710704, -121.810241 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.7107&lon=-121.8102&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report December 31, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 29844 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX97LA251 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/29844/pdf - Page: https://openairdocs.org/ntsb/LAX97LA251 ## Probable cause failure of the student pilot to maintain adequate airspeed during a go-around. Trees at the departure end of the runway were a related factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - go-around - initiated, pilot in command - airspeed - not maintained, pilot in command (cause) - climb - not possible, pilot in command - On ground/water collision with object, landing - roll - object - tree(s) (contributing factor) ## Analysis The student pilot was remaining in closed traffic to practice crosswind landings. While on short final approach for the 7th landing, he elected to perform a go-around. He increased power and retracted the flaps from 30 to 10 degrees. He then became concerned about a poor rate of climb and low airspeed, and he did not believe that the aircraft would safely clear trees at the departure end of the runway. Deciding to abort the go-around, he landed near the departure end of the runway. The nose wheel struck a concrete curb that marked the end of the runway. The aircraft then became airborne and struck a small tree. Inspection of the aircraft revealed no preexisting anomaly. ## Factual narrative On July 7, 1997, at 1205 hours Pacific daylight time, a Cessna 150M, N8168U, overran runway 33 and collided with trees at the Ranchaero Airport, Chico, California, during a go-around attempt. The aircraft sustained substantial damage, and the student pilot, the sole occupant, was not injured. Visual meteorological conditions existed for the solo cross-country instructional flight and no flight plan was filed. The time of departure from the Ranchero airport was 1110. The student pilot reported that this was his fourth solo flight and was remaining in closed traffic to practice crosswind landings. On final, with 30 degrees of flaps, the student pilot elected to execute a practice go-around. He increased the power to full, and flaps were retracted to 10 degrees. The student pilot noted a poor rate of climb and low aircraft speed. He stated that with low aircraft performance he did not believe that the aircraft would safely clear the trees located at the runway's departure end. He then attempted to land and brake within the remaining length of the runway. The student pilot reported that the aircraft touched down hard at the departure end of the runway and that the nose wheel immediately struck a concrete curb that marked the end of the runway. The aircraft became airborne again and struck a tree. It landed on top of the fallen tree and rolled to a stop. An Federal Aviation Administration (FAA) inspector from the Sacramento, California, Flight Standards District Office, traveled to Chico on July 24, 1997, to inspect the airplane and interview the pilot. In the interview, the student pilot reported that he let the airplane go too far down the runway before attempting the go-around. The aircraft was inspected with no preexisting anomalies noted. The accident was reported to the FAA and the Safety Board on July 17, 1997, at 1230. ## Aircraft - Registration: [N8168U](https://openairdocs.org/aircraft/N8168U), registered now, S/N 15077905, built 1976 (OpenAirDocs) - Reported make and model: Cessna 150M - Registry model: [Cessna 150M](https://openairdocs.org/model/cessna-150m) (registry code 2071830) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15077905 - Airframe hours: 6548 - Engines: Continental O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Ronald E.
