N6175Y

HISTORY OF FLIGHT

On February 22, 2004, approximately 1045 central standard time, a Cessna 210N single-engine airplane, N6175Y, registered to and operated by a private individual, was destroyed upon impact with terrain while maneuvering near Valley Spring, Texas. The non-instrument rated private pilot, sole occupant of the airplane, was fatally injured. The airplane was registered to Baley Aviation, LLC, of Richmond, Texas. Instrument meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight that originated at Midland International Airport (MAF), near Midland, Texas, approximately 0915, and was destined for Sugarland Regional Airport (SGR), near Sugarland, Texas.

A review of voice communications revealed that the pilot had obtained two weather briefings from the San Angelo Flight Service Station (AFSS), San Angelo, Texas, prior to departure. The pilot reported that he would operate under visual flight rules (VFR) and his route of flight would be from Midland to San Angelo to Burnet to Sugarland, Texas, at an altitude of 5,500 feet mean seal level (msl). He planned to depart about 1000.

The first weather briefing was obtained at 0651, at which time, the briefer reported that an AIRMET for instrument flight rules (IFR) was in affect and VFR flight was not recommended across the proposed route of flight. The briefer informed the pilot that the AIRMET for IFR conditions would continue beyond 0900 and end at 1200. The pilot told the briefer that he would call back prior to his departure for another weather briefing.

The second weather briefing was obtained at 0851. The pilot asked for an update to the AIRMET, and wanted to know if it was still in effect. The briefer responded that an update for the AIRMET was not available and to call back in 15 minutes. The pilot then requested weather information for airports along the route of flight. At the end of the briefing, the briefer advised the pilot to contact Flight Service in-flight on 122.6 for updated weather information.

A review of air traffic control (ATC) communications revealed that the pilot did not request weather advisories during the flight.

A review of radar data revealed a target emitting a VFR transponder beacon code traveling southeast bound from Midland toward Valley Spring, Texas. Examination of the last one minute of data revealed the target was at an altitude of 5,400 feet msl, on a heading of 102 degrees at 158 knots, when it made a right 180-degree turn, before the data ended at 1039. The last radar return was approximately 30 degrees, 52 minutes north latitude, and 098 degrees, 46 minutes west longitude, and at an altitude of 5,300 feet msl.

A witness was standing outside his home located about one mile north of the accident site when he heard a small airplane approaching from the south-southeast. He said the airplane was traveling in a west to northwest direction, and seemed to be having engine trouble because it was "speeding up then throttling back." The witness listened to the airplane for approximately one minute, and recalled that the engine noise seemed to get worse because it began to "spit and sputter." Suddenly, the engine "revved" really high then shut off for a split second, followed by a loud explosion, "thud" and smoke. The witness said the weather conditions at the time were light drizzle, haze, limited visibility, and that it had been raining, but had "just let up." He stated that the airplane sounded like it was circling, because it stayed in the area for a few minutes. The witness called 9-1-1 at 1045.

A certified flight instructor provided a statement to the Investigator-In-Charge (IIC) regarding the weather he encountered on an instructional flight from Midland to Burnet (BMQ), near Burnet, Texas. The flight was on an instrument flight rules flight plan and was cleared to an altitude of 7,000 feet msl. At that altitude, they were above a scattered-to-broken layer of clouds, until approximately 30 nautical miles west of the Llano, Texas, VOR. He said, "At that point, we entered the clouds and did not break out again until on the approach at BMQ." They landed at BMQ at 1230, following a fairly lengthy hold at the initial approach fix waiting for traffic inbound to Horseshoe Bay to clear. During this period the weather was deteriorating rapidly. At the time they entered the clouds, the ceiling at Burnet was 2,600 feet msl. The flight instructor said, "Just after passing the Llano VOR, reported ceiling was 1,600 feet msl and by the time we initiated the approach it was called variable between 500 feet msl and 900 feet msl with visibility down to one mile in rain and mist. We broke out right at the MDA for the approach which is 650 feet msl. Shortly after landing, rain intensity increased and the ceiling and visibility were further reduced."

PERSONNEL INFORMATION

The pilot held a private pilot certificate with a rating for airplane single-engine land. His most recent Federal Aviation Administration (FAA) third-class medical certificate was issued on September 24, 2002, with a limitation to wear corrective lenses while flying.

Examination of the pilot's logbooks revealed he had accumulated a total of 580.1 flight hours, of which 1.3 hours were in actual instrument conditions and were conducted under the supervision of a certified flight instructor (CFI).

METEOROLOGICAL INFORMATION

Weather conditions at Midland International Airport, at 0853, were reported as wind from 120 degrees at 5 knots, visibility 10 statute miles, overcast skies at 1,100 feet, temperature 8 degrees Celsius, dew point 4 degrees Celsius, and an altimeter setting of 29.99 inches of Mercury.

Weather conditions at Burnet Municipal Airport, 22 nautical miles west of the accident site, at 1016, were reported as winds from 090 degrees at 4 knots, visibility 10 statute miles, overcast skies at 6,500 feet, and ceiling broken at 2,600 feet. At 1053, the weather was reported as wind from 120 degrees at 7 knots, visibility 9 statue miles, overcast skies at 5,500 feet, and ceiling broken at 3,800 feet.

AIRCRAFT INFORMATION

An examination of the airplane's logbooks revealed that the most recent annual inspection was completed on August 12, 2003, at a total time of 5,923.6 hours.

WRECKAGE AND IMPACT INFORMATION

The wreckage came to rest on private property, fragmented along rolling terrain, with brush and trees, at a field elevation of approximately 1,400 feet. The wreckage was scattered along a linear path that was 835 feet long by 260 feet wide, and oriented on a magnetic heading of 320 degrees. The initial debris field was located at the top of a hill, located 690 feet from the initial impact point. Located at the initial debris field was the outboard section of the left wing, which included the tip and a section of left aileron, a mid-section of left wing and partially attached flap, landing gear, right horizontal stabilizer, right cabin door, and a piece of the windshield. Paint transfer marks from the left wing were found on the right horizontal stabilizer.

Scattered along the path from the initial debris field to the initial impact point was a section of the right elevator, left elevator tip, elevator trim tab, inboard section of the right elevator, sun visor, windshield with compass holder, rudder, a piece of the vertical stabilizer, and the rudder weight. Examination of trees located along the debris field revealed no impact damage except from falling debris.

The initial impact point was a small crater that was approximately 1-2 feet deep. All three propeller blades, the piston dome and propeller spinner were separated from the engine and were embedded in the crater. The first propeller blade had separated, and was wrinkled with heavy rubbing on the non-cambered side. The second blade was bent at a 40-degree angle toward the non-cambered side, and was wrinkled at the tip and loose at the hub. The third blade exhibited heavy rubbing on the leading edge and non-cambered side. Slight twisting towards the direction of rotation was observed. The right wing tip was intact and approximately 5-6 feet from the impact point.

The main wreckage, which included the firewall, cockpit area, right wing, carry thru spar and portion of the left wing spar, and empennage, were located about 80 feet forward of the initial impact point and sustained post impact fire damage. The right wing was found intact, and slightly deformed. The inboard section of the left wing was still attached to the fuselage. Examination of the electrical and vacuum attitude indicator, and directional gyro housings revealed the internal wall of their respective cases exhibited scoring. The flaps and landing gear were found in the retracted position.

The engine was located approximately 10 feet to the left of the main wreckage. The accessories had separated, except for the vacuum pump, fuel pump, and fuel manifold. Most of the intake and exhaust pipes were separated and the oil sump was pushed up into the engine. The oil filter screen was absent of debris. The oil cap for the oil filler was missing. All left side valve covers were shattered and the left side cylinder heads exhibited impact damage. The vacuum pump was in place, and showed little impact damage. The drive shaft rotated freely. The unit was disassembled and the rotor-drum had two cracks and the vanes were intact. The fuel pump exhibited impact damage, and was free to rotate. The drive coupling was intact. The fuel manifold was intact and disassembled. The diaphragm and spring were in place and not damaged. The fuel screen was absent of debris, and small amount of fuel was noted. The fuel selector valve was found in the left tank position. The #1, 3, and 5 spark plugs were intact. The #2,4, and 6 spark plugs were broken in half , light gray in color, and exhibited light deposits on the electro...
