N206GX

HISTORY OF FLIGHT

On June 15, 2012, about 1010 eastern daylight time, a Remos Aircraft GmbH Flugzeugbau Remos GX, special-light sport aircraft (S-LSA), N206GX, operated by a private individual, was substantially damaged when it impacted the ground during an emergency landing at the Carroll County Regional Airport (DMW), Westminster, Maryland. The commercial pilot was fatally injured. Visual meteorological conditions prevailed and no flight plan had been filed for the flight that departed the Frederick Municipal Airport (FDK), Frederick, Maryland, and was destined for the Piseco Airport (K09), Piseco, New York. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.

According to witnesses, the pilot flew the airplane from K09 to Haysfield Airport (MD24), Clarksville, Maryland, during November 2011, where it was disassembled and stored for the winter. It was subsequently reassembled during April 2012. The pilot, who was also a Federal Aviation Administration (FAA) certificated airframe and powerplant mechanic, completed a condition inspection on June 1, 2012. The pilot then flew the airplane to Bay Bridge Airport (W29), Stevensville, Maryland, where a pitot-static system check was performed on June 8, and a Magnum 601 ballistic parachute system was installed on June 12, 2012. The pilot flew to FDK on June 14, 2012, and was planning to fly to K09, with an en route fuel stop, to deliver the airplane to its owner on the day of the accident.

A witness at DMW heard the pilot transmit over the airport common traffic advisory frequency "my elevator has come detached, I need to make a landing on runway 16." Another witness observed the airplane "climb and dive" as it approached the 5,100-foot-long, asphalt runway. A third witness stated the airplane appeared "very, very fast" and approached the runway in a flat or slight nose down pitch attitude. When the airplane was on short final, over the grass area just prior to the runway threshold, it pitched "sharply nose down", and impacted the ground.

PERSONNEL INFORMATION

The pilot, age 64, held a commercial pilot certificate with ratings for airplane single-engine land, airplane multiengine land, glider, and instrument airplane. In addition, he held a flight instructor certificate with ratings for airplane single-engine, airplane multiengine, glider, and instrument airplane. He also held a mechanic certificate with airframe and powerplant ratings. His most recent FAA third-class medical certificate was issued on March 16, 2010.

Review of the pilot's logbook revealed that at the time of the accident, he had accumulated about 3,250 hours of total flight experience, which included about 100 hours during the 1 year preceding the accident. The pilot's first flight in the accident airplane was on April 24, 2011, and at the time of the accident he had accumulated approximately 16 hours of total flight experience in the same make and model as the accident airplane.

The pilot's most recent biennial flight review was conducted on December 1, 2011.

AIRCRAFT INFORMATION

According to records obtained from the FAA, the two-seat, high-wing, fixed tricycle landing gear, S-LSA, serial number 335, was issued a special airworthiness certificate on September 30, 2009, and purchased by its current owner during May 2011. The airplane was powered by a Rotax 912ULS, 100-horsepower engine equipped with a Neuform three-bladed propeller.

The airplane was of composite carbon fiber monocoque construction, and was designed with the ability to fold both wings back to facilitate storage and transportation. In addition, both wings and the horizontal stabilizer were removable. The flight controls were actuated by a series of push-pull rods. The respective control push-pull rods for the left and right ailerons, and elevator featured a "quick-fastener" to disconnect and reconnect the respective flight control push-pull rod.

Each quick-fastener consisted of two-hooks, a locking sleeve, an anti-twist pin, a locking pin, and a locking spring. To connect the respective push-pull rod, the two hooks would be interconnected, and then the locking sleeve would slide over the connection. Once the locking sleeve was in position, the spring would push the locking pin into position and secure the assembly. The anti-twist pin prevented a misalignment of the sleeve, which would prevent the locking pin from sliding into position.

The individual who assisted the pilot with the reassembly of the airplane stated that the pilot was familiar with the operation of the quick-fasteners. He stated that the wings were folded and the horizontal tail was removed for storage. He also reported that there were no issues during the reassembly of the airplane. He further stated that he did not specifically observe the quick-fastener connection associated with the elevator control system.

On March 25, 2009, after a fatal accident involving the improper connection of an aileron quick-faster, Remos Aircraft introduced the anti-twist pin feature, and issued a Safety Directive (SD) which called for an inspection of the aileron and elevator quick-fasteners, an update of the Pilot Operating Handbook (POH) and the addition of warning placards associated the quick-fasteners. Quick Fastener Safety Directive SD-05 was current at the time of the accident. Review of SD-05 noted that the photograph depicting the elevator quick-fastener was depicted with the tail cone, which was secured by two screws removed. According to the manufacturer, it was normal procedure not to remove the tail cone during preflight inspection. A subsequent inspection of an exemplar Remos GX by the NTSB revealed that it was possible to view elevator quick-fastener locking pin with the tail cone installed.

At the time of the accident, the airplane had been operated for about 210 total hours, and about 2 hours since the condition inspection. Review of the inspection checklist utilized by the accident pilot/mechanic during the condition inspection included an inspection of all components and systems that made up the empennage assembly for insecure attachment, and improper component installation.

The mechanic who performed the parachute installation stated that he did not disconnect any of the quick-fasteners. In addition, review of the Parachute Installation Manual for the Magnum 601 ballistic parachute system revealed that it was not necessary to disconnect any of the quick-fasteners to facilitate the installation.

A placard located on the instrument panel stated: "CHECK: Flight System Control and Three Quick Fasteners." There were also placards stating to check the quick fasteners for a secure connection, with associated illustrations, consistent with compliance with the Remos Quick Fastener Safety Directive, located near the respective aileron and elevator push-pull rod quick-fasteners.

Placards located on the center console included: "Remove Lock from BRS Before Flight" and a "Start-Up Checklist" that included "Recovery System Armed."

METEOROLOGICAL INFORMATION

The reported weather at DMW, at 1007, was: winds calm; visibility 10 miles; temperature 21 degrees Celsius (C); dew point 13 degrees C; altimeter 30.31 inches of mercury.

WRECKAGE AND IMPACT INFORMATION

The wreckage was examined at the accident site on June 16, 2012. The airplane impacted the ground about 60 feet prior to runway 16, and about 12 feet to the left of the right runway edge. Debris was scattered south-southeast approximately 350 feet, with the majority of the wreckage found on the grass area that was located immediately off the right side of and parallel to the runway.

All major portions of the airplane were accounted for at the accident site. Both wings and the top portion of the cabin were inverted and found about 220 feet from the initial impact point. The main wreckage was found about 265 feet from the initial impact point. It consisted of the cockpit, which was destroyed, the engine, and the tail assembly aft of the cabin, which remained intact. The ballistic parachute system parachute was not activated and found strewn along the debris path. The activation handle, which was mounted on the center console, was found with the main wreckage and was secured with a padlock. The key for the padlock was found on a key ring, with the ignition key, which remained inserted in the ignition switch.

Examination of the airplane's flight controls revealed that the elevator quick-fastener was disconnected. The left and right aileron quick-fasteners remained connected, and the flight control cables to the rudder remained attached. Damage was noted on the flight control push-pull rods that was consistent with impact damage. The elevator trim tab was about 1/4-inch from the full nose down trim position. Examination of the airplane's engine did not reveal any failures that would have precluded normal operation.

The elevator and aileron quick-fasteners were removed and forwarded to the NTSB Materials Laboratory, Washington, DC, for further examination. In addition, the airplane was equipped with a Dynon Avionics "FlightDEK-D180 combined EFIS and EMS" unit, and a Garmin 496 global positioning system (GPS) receiver, which were forwarded to the NTSB Vehicle Recorders Division for data download.

MEDICAL AND PATHOLOGICAL INFORMATION

An autopsy was performed on the pilot by the Office of the Chief Medical Examiner, Baltimore, Maryland. The autopsy report revealed the cause of death as "multiple injuries."

Toxicological testing performed on the pilot by the FAA Bioaeronautical Science Research Laboratory, Oklahoma City, Oklahoma with negative for alcohol and positive for Doxepin, a prescription antidepressant, Nordoxepin, a metabolite of Doxepin, and Pioglitazone, a prescription anti-diabetic agent.

During the pilot's most recent FAA medical examination, he listed "occasional aspirin" as medications he was currently taking.
