NTSB summary

On September 18, 2011, about 1721 central daylight time, an amateur-built, experimental light sport (E-LSA) Aero Adventure Zephyr II airplane, N3577F, operated by a private individual, was substantially damaged when it impacted terrain during takeoff from Sylacauga Municipal Airport (SCD), Sylacauga, Alabama. The certificated private pilot was fatally injured. The personal flight was 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. According to a Federal Aviation Administration (FAA) inspector, the pilot had removed pontoons from the airplane and installed a tricycle landing gear. To compensate for the subsequent tail-heavy condition, the pilot utilized an elevator trim tab extension; however, for the accident takeoff, the extension was left in the pilot's hangar and not installed on the airplane. During takeoff roll on runway 27, as the airplane became airborne, it nosed over and impacted a grassy area to the right, between the runway and taxiway. The airplane came to rest in the grassy area in a nose-down attitude. The FAA inspector added that a witness, who was watching airplanes from behind the airport fence, reported the accident law enforcement. The witness observed the accident airplane take off normally and climb out; however, the left wing then went straight up and right wing dropped suddenly. The airplane impacted the ground along the right side of the runway. Another FAA inspector examined the wreckage and confirmed flight control continu

Probable cause

The pilot's incapacitation due to a heart attack during takeoff, which led to an in-flight loss of airplane control.

    Phase and cause come from the NTSB’s own coding of each accident, which only exists from 2008 on, so these two filters leave out 1982–2007. Cause categories are only recorded for some accidents, and early findings can change.
