Experimental French Racer Went Down In Camarillo, CA
The pilot of an experimental French racing airplane told the
NTSB he was experiencing engine problems before he put the airplane
down in a field near the Camarillo, CA airport. Fortunately, the
pilot was only slightly injured in the accident, but the same could
not be said for the "Big Frog."
NTSB Identification: WPR12LA081
14 CFR Part 91: General Aviation
Accident occurred Tuesday, January 24, 2012 in Camarillo, CA
Aircraft: MAS Events Nemesis, registration: F-WNXT
Injuries: 1 Minor.
This is preliminary information, subject to change, and may

the final report has been completed.
On January 24, 2012, about 1555 Pacific standard time, an
experimental amateur-built Nemesis NXT, French registration F-WNXT,
sustained substantial damage during a forced landing following a
partial loss of engine power during cruise near Camarillo Airport,
Camarillo, California. The airplane was registered to Dopic, Paris,
France, and operated by the pilot under the provisions of 14 Code
of Federal Regulations Part 91, as a performance evaluation flight
in preparation for a transcontinental speed record attempt. The
airline transport pilot sustained minor injuries. The local flight
departed Camarillo at 1430. Visual meteorological conditions
prevailed, and no flight plan had been filed.
The pilot reported that he departed in the airplane with the
intention of ascertaining the airplane's fuel consumption and
performance parameters in preparation for the record attempt. He
planned on flying for 3 hours, and had serviced the airplane to
capacity with fuel 2 days prior.
The first hour of the flight was uneventful, with the pilot
reporting that all engine parameters were normal. A short time
later, at an altitude of 18,000 mean sea level (msl), he began to
feel a vibration in the airframe. He initially attributed the
vibration to the propeller, and reduced the manifold pressure to
diagnose. The vibration continued, but with reduced intensity, and
as such, he elected to return to Camarillo. The airplane was not
able to maintain altitude, and he noted that the manifold pressure
was now about 20 percent lower than during the cruise portion of
the flight. During the descent, the engine monitoring system
indicated a reduction in exhaust gas temperature for one of the
engine cylinders.

The airplane reached Camarillo Airport while still at an
altitude of about 6,000 feet, and began a circling descent. The
pilot stated that he joined the downwind leg high and fast, and
subsequently initiated a climb in order to reduce airspeed to lower
the landing gear. He then lowered the landing gear lever, but did
not observe the landing gear down indication lights as expected. He
then attempted to extend the landing gear using the emergency
extension system, but still did not observe the down indication. He
then contacted air traffic control tower personnel, and asked for a
visual confirmation of the landing gear position. They reported
that the landing gear was partially extended, and he subsequently
began to initiate a go-around. He maneuvered the airplane to the
downwind leg, while the airspeed began to degrade. The airplane's
airspeed reached 105 knots, and he was unable to maintain altitude.
The pilot became concerned that he would not be able to return to
the airport, and elected to perform an off-field landing in an
adjacent plowed field.
The airplane subsequently landed in the field, striking a berm
about 500 feet beyond the initial touchdown point. After striking
the berm, the airplane rotated, separating both wings, the landing
gear, and sections of the horizontal stabilizer. The fuselage came
to rest on its left side in a manner that prevented the pilot from
opening the canopy. The pilot turned off all of the airplane's
systems, and pulled all the circuit breakers while waiting for
rescue personnel. A witness subsequently arrived at the accident
site a few minutes later, and assisted the pilot in exiting the
airplane.
According to the pilot, the airplane was transported to the
United States from France in August 2011 to perform in the Reno Air
Races as part of the Big Frog Pylon Racing Team. Upon arrival, the
airplane underwent a conditional inspection, and flew in the races.
The airplane was subsequently flown to California, where Federal
Aviation Administration records indicate it was issued a non-US
special flight authorization (SFA) on January 19, 2012, for the
purpose of performing flight evaluations in preparation for the
record attempt. The SFA was valid for 11 days, and required that
the airplane be flown within a 40-mile radius of Camarillo
Airport.
