A factor was the gusty crosswind conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Nose over, landing - roll - weather condition - crosswind (contributing factor) - brakes(normal) - excessive, dual student (cause) - weather condition - gusts - supervision - inadequate, pilot in command(cfi) (cause) ## Analysis The commercial pilot, who was receiving dual instruction for agricultural operations, landed the tailwheel-equipped airplane on runway 34 (4,000-feet long by 50-feet wide). During the landing roll, the airplane nosed over when "excessive braking action took place." The winds at the airport were from 040 degrees at 10-12 knots. The weather observation facility located approximately 34 nautical miles north of the accident site reported the wind from 050 degrees at 11 knots gusting to 18 knots. ## Factual narrative On April 4, 2002, approximately 1200 central standard time, a Grumman G-164A, tail wheel-equipped agricultural airplane, N8916H, sustained substantial damage when it nosed over following an application of the brakes during the landing-roll on runway 34. The airplane was owned and operated by Mid-South General Aviation & Agricultural Training Inc., at Wynne, Arkansas, under 14 Code of Federal Regulations Part 91. The flight instructor and the commercial pilot, who was receiving training for agricultural operations, were not injured. Visual meteorological conditions prevailed for the local instructional flight, and a flight plan was not filed. The flight departed the Wynne Municipal Airport at 0930. On the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2), the flight instructor reported that approximately 1030, a landing was made at a private airstrip for refueling. Subsequently, the aircraft departed the private airstrip for flight training utilizing the Global Positioning System (GPS). During the landing roll on runway 34 (4,000-feet long by 50-feet wide) at the Wynne Municipal Airport, "excessive braking action took place." Subsequently, the airplane nosed over, struck the propeller, and came to rest inverted. The flight instructor reported the winds were from 040 degrees at 10-12 knots. At 1153, the weather observation facility at Jonesboro, Arkansas (approximately 34 nautical miles north of the accident site) reported wind from 050 degrees at 11 knots gusting to 18 knots. The FAA inspector, who responded to the accident site, found the airplane resting inverted. The vertical stabilizer and rudder were crushed and bent. The upper wings were twisted. The flight instructor reported the firewall, propeller, fuel tanks, and wing spars were damaged. ## Aircraft - Registration: [N8916H](https://openairdocs.org/aircraft/N8916H), registered now, S/N 1613, built 1976 (OpenAirDocs) - Reported make and model: Grumman G-164A - Registry model: [Grumman Acft ENG Cor-Schweizer G-164A](https://openairdocs.org/model/grumman-acft-eng-cor-schweizer-g-164a) (registry code 3952801) (OpenAirDocs) - Registry engine: [Pratt & Whitney R1340 series](https://openairdocs.org/engine/pratt-whitney-r1340-series) (registry code 52016, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1613 - Engines: Pratt & Whitney R-985 450 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Mid-South General Aviation Agricultural Training - Airworthiness certificate: Special, Restricted (Special) - Departed: M65, Wynne, AR - Airport: M65, Wynne Municipal, runway 34, 4,024 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
