# NTSB ATL06LA119: Ayres S2R, N61224, Doerun, GA, August 10, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 10, 2006, 14:15 local (18:15 UTC) - Place: Doerun, GA - Coordinates: 31.319999, -83.916664 - Nearby events: https://openairdocs.org/map.md?lat=31.3200&lon=-83.9167&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report March 26, 2007 - Report: Approved by Office Director - Parties: Honeywell, College Park FSDO-11 - NTSB case key (mKey): 64308 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL06LA119 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64308/pdf - Page: https://openairdocs.org/ntsb/ATL06LA119 ## Probable cause The loss of engine power for an underdetermined reason, resulting in a forced landing, an on ground collision with trees, and a post crash fire. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - reason for occurrence undetermined (cause) - Forced landing, descent - emergency - On ground/water collision with object, landing - roll - object - tree(s) - Fire, other ## Analysis The pilot stated he was in cruise flight en route to a spray area when the engine started losing power. He added power, but the interstage turbine temperature increased and the torque decreased. The pilot made a forced landing into a field and was unable to stop the airplane before it collided with trees, separating the main landing gear. The pilot left the accident site, and was returning to the accident site a short time later when a farmer who had been working near the accident site informed the pilot that after he left the airplane it caught on fire. The pilot arrived at the crash site and the airplane was totally engulfed in flames. The engine assembly was sent to the engine manufacturer for examination under the supervision of the FAA. The teardown and examination of the engine disclosed the type and degree of damage to the engine was indicative of engine rotation and operation at the time of impact with the ground. No pre-existing condition was found that would have resulted in or contributed to the reported loss of engine power. ## Factual narrative On August 10, 2006, at 1415 eastern daylight time, an Ayres S2R-65, N61224, registered to Ford Flying Services Inc., operating as a 14 CFR Part 137 aerial application flight, had a reported loss of engine power in cruise flight at 500 feet. The pilot made a forced landing in the vicinity of Doerun, Georgia. Visual meteorological conditions prevailed and no flight plan was filed. The airplane was destroyed by a post crash fire. The commercial pilot reported no injuries. The flight originated from a private airstrip in Doerun, Georgia, on August 10, 2006, at 1410. The pilot stated he was in cruise flight enroute to a spray area located 15 miles northwest of Doerun. The engine started loosing power. He added power and the interstage turbine temperature increased and the torque decreased. He observed a short hay field straight ahead and made a forced landing into the field. He was unable to stop the airplane before it collided with trees separating the main landing gear. The pilot exited the airplane, notified authorities of the accident on his cell phone, and departed the area. The pilot was returning to the accident site a short time later when he met a peanut farmer who had been working near the accident site. The farmer informed the pilot that after he left the airplane in the field that the airplane started smoking and caught on fire. The pilot arrived at the crash site and the airplane was totally engulfed in flames. The engine assembly was forward to the engine manufacturer for examination under the supervision of the FAA. The teardown and examination of the engine disclosed the type and degree of damage to the engine was indicative of engine rotation and operation at the time of impact with the ground. No pre-existing condition was found that would have caused or contributed to the reported loss of engine power. The engine was released to Atlanta Air Recovery on February 8, 2007. ## Aircraft - Registration: [N61224](https://openairdocs.org/deregistered/N61224-2007-05-08), registration cancelled 2007-05-08, S/N G5-102, built 1993 (OpenAirDocs) - Reported make and model: AYRES S2R (G5) - Registry model: [Ayres S2R-G5](https://openairdocs.org/model/ayres-s2r-g5) (registry code 0970218) (OpenAirDocs) - Registry engine: [AiResearch TPE331 series](https://openairdocs.org/engine/airesearch-tpe331-series) (registry code 01517, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: G5-102 - Airframe hours: 4136 - Damage: Destroyed - Fire: On-Ground - Flight: Aerial application, Part 137 - Registered owner: Ford Flying Service Inc - Airworthiness certificate: Special, Restricted (Special) - Last inspection: 100 hour, August 1, 2006, 11 hours before - Departed: Doerun, GA ## Flight crew As NTSB recorded them.
