A factor to the accident was the quartering tailwind. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - directional control - not maintained, pilot in command (cause) - weather condition - crosswind (contributing factor) - weather condition - tailwind (contributing factor) - Gear collapsed, landing - roll - landing gear,main gear - collapsed (cause) ## Analysis The airplane was substantially damaged when it ground looped during landing. According to the pilot, at his last point of departure the airplane experienced a "severe pulling" to the right during landing. The pilot stated that he had a mechanic check the brakes and that the mechanic found no discrepencies. The pilot subsequently continued with his flight. According to the pilot, while on landing roll the airplane pulled sharply to the right again. The pilot said that he was unable to correct and the airplane subsequently ran off the runway and ground looped. During the accident sequence, the main landing gear collapsed. An examination of the brake system and tail wheel assembly revealed no anomalies or malfunctions. The winds were 6 knots and 120 degrees right of runway heading. ## Factual narrative On May 20, 2003, at 1625 central daylight time, a Grumman G-164A, N7855, received substantial damage during a ground loop while landing on runway 35 (4,436 feet by 100 feet, asphalt) at the North Platte Regional Airport (KLBF), North Platte, Nebraska. The pilot reported no injuries. The 14 CFR Part 91 flight departed Central City Airport (07K), Central City, Nebraska, at 1500 without a flight plan. Visual meteorological conditions prevailed at the time of the accident. According to the pilot, at his last point of departure, the aircraft experienced a "severe pulling" to the right during landing. He stated he had a mechanic inspect the airplane and the mechanic found no discrepencies. The pilot reported that, while on landing roll at LBF, the aircraft pulled sharply to the right again. The pilot stated he was unable to rectify the situation and went off the runway. The airplane subsequently ground looped and the main landing gear collapsed. The pilot reported a total time of 1,030.5 hours, of which 16 hours were in the same make and model as the accident airplane. All 16 hours were in the last 30 days. The Federal Aviation Administration examined the brake system and tail wheel assembly and reported no anomalies or malfunctions. The weather reporting station at the accident airport recorded the winds at 1553 as 6 knots at 110 degrees. At 1653 the winds were reported at the accident airport at 080 degrees at 6 knots. ## Aircraft - Registration: [N7855](https://openairdocs.org/aircraft/N7855), registered now, S/N 803 (OpenAirDocs) - Reported make and model: Grumman G-164A - Registry model: [Grumman G-164A](https://openairdocs.org/model/grumman-g-164a) (registry code 3952704) (OpenAirDocs) - Registry engine: [Pratt & Whitney R1340 series](https://openairdocs.org/engine/pratt-whitney-r1340-series) (registry code 52016, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 803 - Airframe hours: 3000 - Engines: Pratt & Whitney R-985 450 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: David Sheppard - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, April 1, 2003, 16 hours before - Departed: 07K, Central City, NE - Destination: Unknown - Airport: KLBF, North Platte Regional Field, runway 35, 4,436 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
