# NTSB CHI04LA217: Grumman G-164-B, N6677Q, Bradford, IL, August 6, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 6, 2004, 08:05 local (13:05 UTC) - Place: Bradford, IL - Coordinates: 41.297222, -89.53778 - Nearby events: https://openairdocs.org/map.md?lat=41.2972&lon=-89.5378&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report July 7, 2005 - Report: Approved by Office Director - Parties: FAA - NTSB case key (mKey): 60052 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI04LA217 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/60052/pdf - Page: https://openairdocs.org/ntsb/CHI04LA217 ## Probable cause The pilot's misjudgment of speed and distance, and his failure to perform a go-around. Additional factors were the wet runway and the ditch. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - distance/speed - misjudged, pilot in command (cause) - go-around - not performed, pilot in command (cause) - terrain condition - wet (contributing factor) - On ground/water encounter with terrain/water, landing - roll - terrain condition - ditch (contributing factor) - terrain condition - ground ## Analysis The airplane sustained substantial damage when it contacted a ditch and nosed over after it overran the end of a 2,400 foot grass airstrip. The pilot reported that he circled the grass airstrip once before setting up for a landing to the south on the north/south runway. He landed "as short on the north end as the railroad tracks would allow." He reported the brakes did not feel "as effective as normal." He pumped the brakes twice but they failed to slow the airplane. He reported that it was too late to "power-up and go around," and the airplane departed the end of the runway. The airplane hit a small ditch and it nosed over. The inspection of the brake system revealed the brakes operated normally. No mechanical deficiencies were observed. A witness reported the grass was wet due to a heavy dew on the morning of the accident. He reported that he observed the airplane on final approach for landing. He reported that the airplane was too high and it landed past the first one-third of the runway. He reported the pilot "used up quite a bit of runway before he touched down." He reported that there was no way the airplane was going to stop on the runway due to the dew on the grass and the speed of the airplane. ## Factual narrative On August 6, 2004, at 0805 central daylight time, a Gruman G-164-B, N6677Q, sustained substantial damaged when it contacted a ditch and nosed over after it departed the end of a 2,400 foot grass airstrip near Bradford, Illinois. The commercial pilot was not injured. The 14 CFR Part 137 aerial spraying flight departed a grass airstrip near Fenton, Illinois, at 0740, and was landing at the grass airstrip near Bradford, Illinois, for fuel and chemicals. Visual meteorological conditions prevailed. No flight plan was filed. The pilot reported that he circled the grass airstrip once before setting up for a landing to the south on the north/south runway. He reported that he landed "as short on the north end as the railroad tracks would allow." He reported the brakes did not feel "as effective as normal." He pumped the brakes twice but they failed to slow the airplane. He reported that it was too late to "power-up and go around," and the airplane departed the end of the runway. The airplane hit a small ditch and it nosed over. A Federal Aviation Administration airworthiness inspector examined the airplane. He reported that the brake system was checked and it worked normally. He reported that there was nothing wrong mechanically with the airplane. A witness reported that he observed the airplane landing at the grass airstrip. He reported the grass was wet due to a heavy dew on the morning of the accident. He reported the final approach for landing was too high and the airplane landed past the first one-third of the runway. He reported the pilot "used up quit a bit of runway before he touched down." He reported that there was no way the airplane was going to stop on the runway due to the dew on the grass and the speed of the airplane. ## Aircraft - Registration: [N6677Q](https://openairdocs.org/aircraft/N6677Q), registered now, S/N 198B, built 1977 (OpenAirDocs) - Reported make and model: Grumman G-164-B - Registry model: [Grumman Acft ENG Cor-Schweizer G-164B](https://openairdocs.org/model/grumman-acft-eng-cor-schweizer-g-164b) (registry code 3952802) (OpenAirDocs) - Registry engine: [Pratt & Whitney R-985 series](https://openairdocs.org/engine/pratt-whitney-r-985-series) (registry code 52008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 198B - Airframe hours: 4993 - Engines: Pratt & Whitney 985 450 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: CE-Air Inc. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, December 1, 2003, 28 hours before - Departed: Fenton, IL - Destination: Bradford, IL - Airport: Private Airstrip, runway 18, 2,000 × 75 ft, grass/turf ## Flight crew As NTSB recorded them.
