Probable cause
The NTSB’s determination of the probable cause, and any contributing factors.
The pilot's VFR flight into IMC and his subsequent failure to maintain terrain clearance. The pilot's inadequate inflight planning/decision, mountain obscuration, trees and high terrain were factors.
Analysis
The airplane flew into terrain while maneuvering after encountering weather. Before the first leg of the two-leg on-demand air taxi flight began, the pilot had checked the weather with the FSS for the entire route of flight. The specialist reported mountain obscuration and reduced visibility with rain and fog/overcast. The worst of the weather was reported for the second leg of the flight through the mountain pass with the fog/overcast reported as indefinite at 100 feet. After departure from the originating airport, the pilot requested an updated weather briefing. The weather report was similar and had not changed significantly. The flight landed at the first destination without incident. While on the ground, the pilot once again contacted the FSS to get an updated briefing for the final leg of the flight. The specialist reported that VFR flight was still not recommended and that there were AIRMETs for mountainous terrain obscured and occasional IFR conditions. An automated surface observing system (ASOS) is located at the mountain pass through which the flight was intending to fly. The ASOS at the time was reporting IFR with visibility 1/4 mile in fog, and ceiling broken at 100 feet, and overcast at 600 feet. The destination airport was reporting moderate to heavy showers which were slowly moving in. The specialist recommended to the pilot that he should wait at the airport as the forecast was showing an improving trend throughout the day. A witness traveling westbound on the interstate that runs east/west through the mountain pass, reported that she observed an aircraft traveling eastbound directly over the interstate. She estimated that the aircraft was just below the ceiling, which was a solid layer about 500 feet agl. She stated that from about 1 mile east to 1 mile west of the top of the pass, the clouds were directly on the road. As she descended lower in the valley, the cloud bases were no higher than about 500 feet agl. On site investigation of the wreckage indicated that the aircraft collided with several trees and subsequently the steeply rising terrain in an easterly direction on the south side of the interstate and about 150 feet above the roadway surface. At the approximate time of the accident, the ASOS located about 3 miles east of the accident site was reporting an indefinite ceiling at 100 feet, and a visibility of zero.

History of flight
On June 8, 2006, about 1315 Pacific daylight time, a Cessna TU206G, N5136X, registered to and operated by Majestic Alliance of Everett, Washington, as a 14 CFR Part 135 on-demand air taxi flight, collided with trees and rising terrain near Mullan, Idaho. Instrument meteorological conditions were reported in the area of the accident site and no flight plan was filed. The aircraft was substantially damaged and the commercial pilot and passenger were fatally injured. The flight departed from Coeur d'Alene (COE), Idaho, sometime after 1235, and was en route to Missoula, (MSO) Montana. There was no report of an emergency locator transmitter signal.
The employer of the passenger reported that this flight had been scheduled with the pilot for about a week in advance. The purpose of the flight was to deliver components to Empire Airlines in MSO. The employer reported that his company had been using this pilot for several years and that they were friends. This route had been flown many times before. The morning of the flight, the pilot had called this person and stated that the weather in Missoula was socked in, but he was getting a clearance to make the flight. The plan was to depart Everett, Paine Field (PAE) about 0800 with a stop at COE to deliver some equipment, and then to continue on to MSO. This person stated that there was some urgency to get the equipment to Missoula as Empire had an aircraft on the ground awaiting their arrival.
Recorded communications between the pilot and the Federal Aviation Administration (FAA) indicated that the pilot contacted Seattle Automated Flight Service Station (AFSS) at 0813 for a weather briefing and to file an Instrument Flight Rules (IFR) flight plan from PAE to COE. The pilot reported the time of departure as 0935 for the one hour forty-five minute flight. At 0941, the pilot contacted Seattle Flight Watch to request a weather update for COE. The flight landed in COE sometime after 1100. Records obtained from South Field Fuel, indicated that the aircraft was fueled with 32.60 gallons of 100LL at 1147. At 1224, the pilot contacted Seattle AFSS indicating that he was in COE and requested the weather for Mullan Pass. The conversation concluded at 1234. The pilot did not file a flight plan or indicate when he was going to depart from COE. There were no in-flight communications recorded after the flight departed from COE.
At 1315 a witness traveling westbound on Interstate 90, near the town of Mullan, reported that she observed a red and white aircraft traveling eastbound directly over the Interstate. She estimated that the aircraft was just below the ceiling, which was a solid layer about 500 feet above ground level. The witness stated that she departed from Missoula about 1230 mountain daylight time and that the weather in Missoula was a little bit better. The ceiling bases were solid from St. Regis, Montana, to Mullan Pass. She stated that the precipitation was light to heavy rain along the route. From about one mile east to one mile west of Mullan Pass, the clouds were directly on the road. As she descended lower in the valley, the cloud bases were no higher than about 500 feet above the road.
Approximately 1440, the Shoshone County Sheriff's Office received a call from an individual who reported that he came across aircraft wreckage while riding his motorcycle on a dirt road. Deputies were dispatched to the area and confirmed that the accident site was located on a dirt road about 100-200 feet directly above Interstate 90 near the Lookout Pass Ski Resort. The terrain rose steeply above the interstate to the dirt road. The aircraft collided with several trees on the north side of the dirt road before colliding with the rising terrain on the opposite side and about 30 feet up from the dirt road.
Personnel information
At the time of the accident, the pilot held a commercial certificate for airplane single engine land operations and instrument flight. The pilot's flight logbooks were not made available for review, however, the pilot's airman medical records indicated that on June 7, 2005, during the pilot's last second class medical examination, he reported a total flight time of 4,350 hours, with 100 hours in the preceding 6 months. A one page flight log was recovered from the wreckage that indicated flight times dating from December 20, 2005, to May 15, 2006. Total flight time accumulated during this period totaled 59.2 hours.
On January 11, 2006, the pilot successfully passed a Federal Aviation Administration Airman Competency/Proficiency Check for operations conducted under 14 CFR Part 135 operations.
Air Carrier Certificate number IRTA552T was issued to the pilot effective on June 26, 1991, operating under the names; Majestic Alliance and Air Transfer Services, Inc. The principal base of operation was located at Everett, Washington.
A review of the Operations Specifications, indicated that the single-pilot certificate holder was authorized to conduct on-demand operations in Cessna TU206G, N5136X, for the carriage of passengers and cargo under day and night visual flight rule conditions. The Operations Specification further indicated that, "The certificate holder is not authorized and shall not: Conduct IFR en route operations." The Operational Control section of the specification indicated that, "An FAA flight plan will be filed with the local Flight Service Station for each flight under FAR 135."
