# NTSB CHI94LA247: Cessna 182, N2564R, Greenwood, IL, July 26, 1994 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 26, 1994, 18:00 local (23:00 UTC) - Place: Greenwood, IL - Coordinates: 42.379341, -88.359527 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=42.3793&lon=-88.3595&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report February 24, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 9611 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI94LA247 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9611/pdf - Page: https://openairdocs.org/ntsb/CHI94LA247 ## Probable cause the pilot-in-command's (CFI) inadequate aircraft preflight inspection and improper aborted takeoff. Related factors are the blocked pitot/static system, and the CFI's inadequate supervision during the preflight and takeoff. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, takeoff - aborted - pitot/static system - blocked(total) (contributing factor) - aircraft preflight - inadequate, pilot in command(cfi) (cause) - flight/nav instruments,airspeed indicator - false indication - supervision - inadequate, pilot in command(cfi) (contributing factor) - aborted takeoff - improper (contributing factor) ## Analysis THE PRIVATE PILOT AND FLIGHT INSTRUCTOR REPORTED THE FLIGHT WAS INTENDED TO BE A DUAL INSTRUMENT INSTRUCTIONAL FLIGHT. THEY STATED EVERYTHING SEEMED NORMAL UNTIL THE AIRPLANE WAS ABOUT 1/3 DOWN THE RUNWAY ON THE TAKEOFF ROLL, AND THEY NOTICED THE AIRSPEED INDICATOR WAS INDICATING ZERO. THEY STATED THEY REDUCED THE THROTTLE AND APPLIED BRAKES. THE AIRPLANE RAN OFF THE DEPARTURE END OF THE 3,200 FOOT RUNWAY, CONTINUED UP AN EMBANKMENT AND CAME TO REST IN A CORN FIELD. POSTACCIDENT INVESTIGATION REVEALED A MUD DAUBER NEST BLOCKED THE PITOT TUBE. A WITNESS REPORTED THE PILOTS APPLIED BRAKES, WITH FULL POWER APPLIED FOR ABOUT 1,000 FEET. HE STATED HE HEARD THEM THROTTLE BACK WHEN THE AIRPLANE WAS NEAR THE END OF THE RUNWAY. THE WITNESS ESTIMATED THE AIRPLANE'S SPEED AT 40 MPH WHEN IT LEFT THE RUNWAY. ## Factual narrative On July 26, 1994, at 1800 central daylight time, a Cessna 182, N2564R, piloted by the private pilot/registered owner, sustained substantial damage when it ran off the end of Runway 27 during an aborted takeoff at Galt Airport, in Greenwood, Illinois. The private pilot, the certificated flight instructor (CFI) and the one passenger aboard reported no injuries. Visual meteorological conditions prevailed for the flight, no flight plan was filed. The flight operated under 14 CFR Part 91, and originated from Greenwood, Illinois about 1759, with an intended destination of Rockford, Illinois. Both pilots reported the flight was intended as a dual instrument instructional flight. They planned to depart the uncontrolled airport VFR, and practice instrument approaches at the Greater Rockford Airport in Rockford, Illinois. Both pilots stated the airplane preflight inspection and engine run up proceeded normally. The CFI reported nothing unusual was observed until the airplane was about 1/3 down the runway, and "...had not yet begun to lift off....at this point where the plane is usually breaking ground. The airspeed indicator was indicating zero." The private pilot stated he reduced the throttle and began braking to abort the takeoff. The CFI reported she assisted in brake application and keeping the airplane under control. The airplane ran off the departure end of the 3,200 foot runway, continued up a small hill and came to rest in a corn field. Postaccident examination revealed a mud dauber nest blocking the pitot tube. There was no evidence of preimpact mechanical malfunction. Postaccident investigation revealed a pair of heavy black skid marks, approximately 600 feet long, down the runway. The skid marks continued into the grass, up the hill, then disappeared briefly, to reappear in the corn field where the airplane came to rest. The airport manager witnessed the airplane as it ran off the runway, and he estimated its speed to be 40 mph. He stated both pilots were "standing on the brakes, with full power applied, for about 1,000 feet...they finally throttled back near the end of the pavement." A record of telephone conversation is appended. ## Aircraft - Registration: [N2564R](https://openairdocs.org/aircraft/N2564R), registered now, S/N 18258264, built 1967 (OpenAirDocs) - Reported make and model: CESSNA 182 - Registry model: [Cessna 182K](https://openairdocs.org/model/cessna-182k) (registry code 2072724) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18258264 - Airframe hours: 2569 - Engines: CONTINENTAL O-470-R 230 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Wygrzyn, Richard S. - Registered owner: Wygrzyn, Richard S. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, January 11, 1994, 84 hours before - Destination: RFD, ROCKFORD, IL - Airport: 10C, Galt, runway 27, 3,200 × 36 ft, asphalt ## Flight crew As NTSB recorded them.

No indicated airspeed on takeoff. Aborted. Overran runway. Mud dauber nest had blocked pitot tube. Aborted too late From the NTSB's public API. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
