HISTORY OF FLIGHT
On August 7, 2005, at an undetermined time, a Fantasy Air Allegro 2000 light sport airplane, N9164M, registered to and operated by Sport Inc., as a 14 CFR Part 91 instructional flight, collided with the ground in the vicinity of Supply, North Carolina. The airplane was located during an aerial search on August 7, 2005, at 1630. Visual meteorological conditions prevailed and no flight plan was filed. The airplane received substantial damage. The flight instructor and student pilot were fatally injured. The flight originated from Brunswick County Airport, Oak Island, North Carolina, on August 7, 2005, at approximately 1030 eastern daylight time.
PERSONNEL INFORMATION
Flight Instructor.
Review of information on file with the Federal Aviation Administration (FAA) Airman's Certification Division, Oklahoma City, Oklahoma, revealed the flight instructor was issued a commercial pilot certificate on August 19, 2005, with ratings for rotorcraft-helicopter and instrument helicopter. The flight instructor also held a private pilot certificate issued on August 19, 2005 with ratings for airplane single engine land. The flight instructor was also issued a ground instructor certificate on August 19, 2005.
The flight instructor was issued a Sport Pilot Flight Instructor certificate on June 11, 2005. The flight instructor's last recorded flight review was conducted on May 8, 2005. The flight instructor indicated on his application for the Sport Pilot Flight Instructor certificate that he had accumulated 2,149 total flight hours of which 20 hours were in the Allegro 2000 airplane. The flight instructor's logbook was not located in the airplane in accordance with 14 CFR Part 61.51 (c) (5). Review of the flight instructor's logbook revealed he had logged a total of 2,995.5 total flight hours of which 2,708.7 hours were as pilot-in-command. The flight instructor's first flight in an Allegro 2000 was on November 17, 2004. The flight instructor had accumulated 104.2 total flight hours in the Allegro 2000, of which 3 hours were dual instruction, and 67.7 hours were as a Sport Pilot instructor. The flight instructor had flown 104.2 hours in the last 90 days and 53.7 hours in the last 30 days not including the accident flight.
The flight instructor held an FAA third-class medical certificate issued on August 23, 2004, with the restriction "must have available glasses for near vision. Not valid for any class after August 31, 2005." Review of the flight instructor's application for the third-class medical certificate revealed the flight instructor had accumulated 2,850 total flight hours of which 50 were flown in the last six months. The flight instructor's pilot's logbook or other evidence of required authorized instructor endorsements on all flights when providing flight training was not located in the airplane in accordance with 14 CFR Part 61.51 (c) (5).
Student Pilot.
The student pilot held a valid North Carolina, Class C drivers license with no restrictions in accordance with 14 CFR Part 61.303, Subpart J, Sport Pilot (a) (2). An FAA third class medical certificate was not required. Review of the student pilot's logbook revealed he had flown seven dual flights with the flight instructor for a total of 10.6 hours not including the accident flight. No endorsements were recorded in the logbook.
AIRCRAFT INFORMATION
The Fantasy Air Allegro 2000 is a high-wing, single-engine, light sport airplane manufactured in the Czech Republic and distributed by B-BAR-D Aviation in Whitsett, North Carolina. The two-seat airplane was certified as a production aircraft by the FAA in the Special Light Sport Aircraft (S-LSA) category.
The airplane maintenance logbooks were not located.
The Allegro 2000 Operating Manual indicates that the stall speed at the maximum take-off weight 560 lbs-level flight is "…53 miles per hour (MPH) indicated airspeed (IAS) or 51 MPH calibrated airspeed (CAS) with zero flaps at idle engine power. The airplane will stall at 48 MPH IAS or 47 MPH CAS with flaps at position one at idle engine power. The airplane will stall at 45 MPH IAS or 44 MPH CAS with flaps at position two at idle engine power."
METEOROLOGICAL INFORMATION
The Brunswick County Airport, Oak Island, North Carolina, 1440 surface weather observation was: winds 100-magnetic, at six knots, visibility 10 miles, sky clear, temperature 81 degrees Fahrenheit, dew-point 66-degrees Fahrenheit, and altimeter 30.15.
WRECKAGE SITE INFORMATION
The wreckage was located in an open field adjacent to a highway in Supply, North Carolina. Examination of the crash site revealed the airplane collided with the ground on a heading of 060-degrees magnetic and came to rest 40 yards past the initial point of impact. One propeller blade was separated at the initial point of impact and was delaminated. The FAA inspector on scene stated there was no evidence of broken tree branches from a tree line located about 35 yards northwest of the initial point of impact. A friend, who was also a student of the deceased instructor pilot, stated a broken tree branch was located about 30 feet from the tree line. The friend and the FAA could not determine where the tree branch came from or if there was any other damage in the trees. Browning of vegetation was located along the crash debris line extending 20 yards along the direction of travel behind the main wreckage.
The wreckage was recovered by a local wrecker service and transported to the flight instructor's hangar located at Brunswick County Airport, Oak Island, North Carolina, on August 7, 2005. The wreckage was picked up and transported to Griffin, Georgia, on August 10, 2005 by a recovery company under the supervision of Safety Board investigators.
