NTSB Factual Report

On January 5, 2017, about 1700 eastern standard time, an Aircraft MFG & Development Co, CH 2000, N683AM, was substantially damaged when it collided with trees, during the initial climb after takeoff from Cobb County International Airport (RYY), Atlanta, Georgia. The private pilot was seriously injured. The airplane was operated by the private pilot as a personal flight conducted under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no flight plan was filed for the planned local flight.

The pilot reported that he had planned to perform some touch-and-go landings at RYY. During initial takeoff on runway 27, he applied full power and initiated a climb at the appropriate airspeed. Shortly thereafter, the airplane experienced a loss of engine power and climb performance. The left wing and nose dropped, but no stall warning horn sounded. The pilot leveled the wings and configured the airplane quickly for landing, before colliding with trees.

The pilot further reported that he had acquired his private pilot license in 2009, but had not flown between 2010 and 2015. He also had not completed a current flight review. The pilot reported a total flight experience of 143.3 hours; of which, 59 hours were in the same make and model as the accident airplane. He had flown 21.3 hours during the 90-day period preceding the accident.

According to a Federal Aviation Administration (FAA) inspector, air traffic control personnel observed the airplane about 200 feet above ground level as it was approximately 900 feet from the beginning of runway 27. The airplane then drifted left, descended, and impacted trees.

The inspector further stated that the airplane came to rest in a wooded area south of runway 27, about 1,400 feet from the beginning of the runway. The inspector examined the wreckage at the accident site and noted that during the impact, the airplane suffered damage to both wings and the fuselage. The inspector observed the flaps in the full-extended position. He also found an airplane operating handbook in the cockpit and observed that it was open to a page describing short field takeoffs and landings. He added that due to impact damage, some fuel had leaked from the airplane.

After the wreckage was recovered to a salvage facility, a test-run of the engine on the airframe was conducted under the supervision of an FAA inspector. The engine started without hesitation and ran for several minutes at different power settings, including full power.

The recorded wind at RYY, at 1647, was from 300 degrees at 3 knots.

NTSB Probable Cause

The pilot's exceedance of the airplane's critical angle of attack while attempting a short-field takeoff, which resulted in an aerodynamic stall.
