Thanks, but I was looking for the Transport Safety Board report.
Interesting to note that with EFIS equipped aircraft more and more information
is available to be examined by the accident investigation team. The recent IVP
turbine accidnet at Provo, UT was equipped with Chelton screens. Data was
downloaded and provided the following information, (mind you, this is on the
preliminary report):
"Following recovery of the wreckage, two Chelton Electronic Flight
Instrument System (EFIS) displays were removed from the airplane's instrument
panel and an attempt was made to recover the data recorded on the internal flash
memory cards of each unit. Data from the accident flight was successfully
recovered from one of the two cards. Preliminary review of the recorded data
indicated the following:
The data began at avionics power up on 6/8/2006,
at 22:46:18, during engine start. Takeoff roll began at 22:53:25 and the flight
proceeded nominally. Throughout the flight, fuel pressure, oil pressure and oil
temperature remained within limits, and the engine and electrical systems showed
no abnormal indications.
At 23:40:07, the aircraft passed due south of
the Fairfield VOR (FFU) with a heading of 027 in a right turn (58 degrees per
minute), level at a pressure altitude of 14,107 feet, and an indicated airspeed
of 214 knots.
At 23:41:32, the aircraft increased the turn rate and
performed a descending right 360-degree turn, beginning at 11,737 feet and
ending at 23:43:14 at 7,007 feet.
At 23:43:33, the N2 (propeller) speed
increased from about 1,850 to about 2,030 RPM without a change in torque or fuel
flow, indicating a change in the commanded propeller pitch to a flatter
pitch/higher drag setting.
At 23:43:54, the aircraft was aligned for
landing on runway 13 and was approximately 1.5 miles from the threshold at a
pressure altitude of 5,247 feet (about 750 feet above the threshold elevation of
4,497 feet) with an indicated airspeed of 210 knots and a descent rate of 1,900
foot per minute (fpm).
At 23:44:06, the aircraft began a right turn.
Altitude was 4,977 feet, airspeed 197 knots and descent rate 1,300 fpm. As the
right turn continued, the airspeed decayed.
The final data point was at
23:44:43, latitude 40:14.064 N, longitude 111:45.540 W. Heading was 332 degrees,
altitude 4,567 feet, airspeed 123 knots and descent rate 1,300 fpm. {Jeff's
note, the Provo field elevation is 4497' -- the last data point was at within
100' of splashdown.)
HPAT recommends that the BE NO night or IMC flying in the first 100 hours.
The new owner of this turbine reportedly ignored that advice.
