# NTSB SEA00LA140: Cessna 188, N731GR, Lone Pine, OR, July 21, 2000 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: July 21, 2000, 07:50 local (14:50 UTC) - Place: Lone Pine, OR - Coordinates: 44.100658, -120.659721 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=44.1007&lon=-120.6597&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report March 2, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49797 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA00LA140 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49797/pdf - Page: https://openairdocs.org/ntsb/SEA00LA140 ## Probable cause The complete loss of engine power for undetermined reasons. Factors include an irrigation system in the field where the forced landing took place, and the pilot's intentional initiation of a ground loop in order to miss the pipes of the irrigation system. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, maneuvering - reason for occurrence undetermined (cause) - On ground/water encounter with terrain/water, landing - roll - ground loop/swerve - intentional, pilot in command (contributing factor) - object - other (contributing factor) ## Analysis During an aerial application run, the aircraft's engine experienced a complete loss of power, and the pilot elected to make a forced landing in an adjacent alfalfa field. Although the touchdown was successful, the aircraft was damaged during a pilot-executed ground loop, which was initiated in order to stop the aircraft before it collided with an irrigation system that was present in the field. ## Factual narrative On July 21, 2000, approximately 0750 Pacific daylight time, a Cessna 188, N731GR, collided with the terrain during an intentional ground loop initiated by the pilot during a forced landing in an alfalfa field near Lone Pine, Oregon. The commercial pilot, who was the sole occupant, received minor injuries, and the aircraft, which was owned and operated by Precision Application, of Madras, Oregon, sustained substantial damage. The 14 CFR Part 137 aerial application flight, which had been in the air about 15 minutes, was operating in visual meteorological conditions. No flight plan had been filed, and the aircraft did not carry an ELT. According to the pilot, while making a chemical application run, the aircraft's engine quit, and he executed a forced landing in an adjacent field of alfalfa. Although the touchdown was successful, the pilot found it necessary to execute an intentional ground loop in order to stop the aircraft prior to encountering an irrigation system in the field where he landed. During the ground loop, the aircrafts empennage sustained substantial damage. No engine anomalies or malfunctions that would have lead to the loss of power were discovered. ## Aircraft - Registration: [N731GR](https://openairdocs.org/deregistered/N731GR-2008-09-15), registration cancelled 2008-09-15, S/N 18802889T, built 1977 (OpenAirDocs) - Reported make and model: Cessna 188 - Registry model: [Cessna A188B](https://openairdocs.org/model/cessna-a188b) (registry code 2073005) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 02889T - Engines: Continental IO-520 300 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Paul H.
