NTSB Factual Report

HISTORY OF FLIGHT

On April 20, 2006, about 2345 eastern daylight time, a Cessna U206G, N120HS, piloted by an instrument rated private pilot, was destroyed on impact with trees and terrain while on approach to runway 35 at the Monroe County Airport (BMG), near Bloomington, Indiana. The personal flight was operating under the provisions of 14 Code of Federal Regulations Part 91. Night instrument meteorological conditions prevailed at the time of the accident. An instrument flight rules (IFR) flight plan was on file and was activated. The pilot and four passengers sustained fatal injuries. The flight originated from the Purdue University Airport (LAF), near Lafayette, Indiana, about 2245.

The person representing N120HS contacted the Terre Haute, Indiana, federal contract facility automated flight service station (AFSS) to get a weather briefing about 2213. The AFSS briefer at position "PF-3" gave the following brief, in part, to the pilot:

The transcript of the weather briefing showed that the pilot did not give an alternate airport to the briefer when the flight plan was filed. The briefer did not ask for an alternate airport and was not required to ask for one.

About 2319, the pilot checked on with the Air Route Traffic Control Center controller working the Shelbyville, Indiana, sector (SHB R). The transcript of their transmissions, in part, stated:

A Continuous Data Recording (CDR) airplane radar track data file was obtained from the Federal Aviation Administration (FAA) in reference to the accident flight. The airplane's radar returns along with their respective altitudes and times were plotted. The plotted data was consistent with an airplane that was being vectored for an instrument landing system (ILS) approach to runway (rwy) 35. The plot showed the airplane at about 5,000 feet on a downwind. At 2334:30, the return showed the airplane was about 4,500 feet on base about ten miles from the approach end of runway 35. The airplane's return at 2337 was right of and approaching the outer marker CLAYE at an altitude of 3,300 feet. About 2337, the pilot made an advisory radio call on the Hulman Approach control frequency for BMG (128.025) that the flight was six miles south of BMG and inbound for runway 35. The last plotted return showed the airplane at 2,000 feet at 2338:34 about two and a half miles from the approach end of runway 35. About 2343, the controller from the Terre Haute International Airport-Hulman Field air traffic control tower, near Terre Haute, Indiana, who was working the approach frequency, advised the flight that the BMG common traffic advisory frequency (CTAF) was 120.77 and the flight responded with "Thank you sir." No further communication was recorded with the accident flight. That plotted chart is appended to the docket material associated with this case.

About 2345, the Monroe County Sheriff responded to telephone calls of a possible airplane crash. About 0400, the wreckage was located in a wooded area about one-half mile from the approach end of runway 35.

Witnesses in the area stated that they were awakened by a low flying aircraft. A witness said that the airplane noise was like a roar. Another described it as an engine acceleration. A thud was heard and no more engine sounds were heard.

PERSONNEL INFORMATION

The pilot held a private pilot certificate with single-engine land, multiengine land, and instrument airplane ratings. The airplane operator reported that the pilot had completed a flight review or equivalent on July 3, 2005. It was further reported that the pilot had accumulated 379.1 hours of total flight time, 24.5 hours of actual instrument time, 51.1 hours of simulated instrument time, 30.4 hours of total flight time in the previous 90 days, 18.0 hours of total flight time in the previous 30 days, and 1.8 hours of total flight time in the previous 24 hours.

She held a FAA third-class medical certificate issued on August 19, 2003, with a limitation for corrective lenses.

AIRCRAFT INFORMATION

N120HS, a Cessna U206G, Stationair 6, serial number U20604728, was a six-place, single engine, high-wing, all-metal airplane of semimonocoque construction. The wings were externally braced and each wing contained a standard integral 46-gallon fuel tank. The airplane was powered by a six-cylinder, horizontally opposed, air cooled, fuel injected, marked as a Continental IO-520-F (17) engine, with serial number 812264-R. The engine was rated at 300 horsepower for five minutes and 285 horsepower continuously. Maintenance records showed that the airplane's propeller was a three-bladed McCauley D3A34C404B model, hub serial number 785309. The airplane was issued a standard airworthiness certificate and was certified for normal category operations.

Maintenance records show that the last annual inspection was performed on June 7, 2005, and that the airplane had accumulated 2,125.7 hours at the time of that inspection. An entry in the records showed that the static system was inspected in accordance with Part 91.411 and 91.413 requirements on May 19, 2005.

The airplane was equipped with a J.P. Instruments Engine Data Management (EDM) 700 system. According to manufacturer's data, the EDM will monitor up to twenty-four critical parameters in your engine, four times a second, with a linearized thermocouple accuracy of better than 0.1 percent or 2 degrees F, has a user selectable index rate, fast response probes, non-volatile long term memory, records and stores data up to 30 hours, and has post-flight data retrieval capabilities.

METEOROLOGICAL INFORMATION

At 2340, the recorded weather at BMG was: Wind 230 degrees at 5 knots; visibility 1 statute mile; present weather mist; sky condition overcast 100 feet; temperature 17 degrees C; dew point 16 degrees C; altimeter 29.94 inches of mercury.

AIDS TO NAVIGATION

There were eight non-precision instrument approaches and one precision approach available at the airport.

The published inbound course for BMG's ILS RWY 35 approach was 354 degrees magnetic, with the published decision height (DH) of 1,045 feet msl. The crossing altitude for the final approach fix (CLAYE) was 2,533 feet msl. The distance between CLAYE and the missed approach point was 5.1 nautical miles (nm). The airport elevation was 846 feet msl.

The published weather minimums for the ILS RWY 35 approach were a 200-foot ceiling and one-half mile visibility for category A, B, C, and D aircraft.

On April 21, 2006 the FAA conducted a post aircraft accident technical inspection and found the ILS system was operating normally.

AIRPORT INFORMATION

BMG had two asphalt-surfaced runways, 17/35 and 6/24. Runway 17/35 was 6,500 feet long and 150 feet wide. Runway 35 was equipped with a medium intensity approach lighting system with runway alignment indicator lights (MALSR) and high intensity runway lights (HIRL). Runways 6,17, and 24 were equipped with visual approach slope indicators (VASI) located on the left side of their respective runways.

The airport was serviced by an Air Traffic Control tower. The tower was attended from 0630 - 2130 local. After hour local traffic communications were accomplished via the published airport CTAF 120.775 megahertz (MHz). The tower did not record the CTAF transmissions made after hours. Indianapolis Approach provided approach/departure control services for the airport.

The pilot controlled lighting function of the approach lights was not operative. The approach lights were turned on before the tower was closed.

WRECKAGE AND IMPACT INFORMATION

The airplane came to rest inver

NTSB Probable Cause

The pilot's continued descent below decision height and not maintaining adequate altitude/clearance from the trees while on approach. Factors were the the night lighting conditions, and the mist.
