An additional cause was the low altitude of an aerial application operation. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, maneuvering - aerial application - reason for occurrence undetermined (cause) - Forced landing, descent - emergency - In flight collision with terrain/water, emergency descent/landing - terrain condition - ground - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command (cause) - altitude - low (cause) ## Analysis The airplane impacted an agricultural field during an aerial application flight. Examination of the accident site revealed both fuel tanks were broken open and did not contain any residual fuel. There was no "heavy" fuel smell. The propeller blades were deformed rearwards consistent with no power. The flaps were extended. The main landing gear impacted a ditch and were still attached to the airplane. The left wing impacted an embankment. ## Factual narrative On June 20, 2007, at 1352 central daylight time, an Ayres Corporation S2R-T15, N113CA, operated by Custom Air Inc., as an aerial application airplane, impacted a bean field while maneuvering near Stuttgart, Arkansas.
