Analysis
On November 5, 2013, about 1912 central standard time (cst), a Piper PA-32R-301, N408DM, registered to RFG LLC and operated by Wisconsin Aviation, collided with trees and the terrain during an instrument approach to the Kirksville Regional Airport (IRK), Kirksville, Missouri. The certificated flight instructor (CFI) and private pilot were fatally injured. The airplane was destroyed. The business/instructional flight was being operated under 14 Code of Federal Regulations Part 91. The airplane was operating in instrument meteorological conditions (IMC) shortly before the accident and an instrument flight plan was filed. The flight originated from the Centennial Airport (APA), Denver, Colorado, about 1543.
According to the operator of the airplane the private pilot had flown to Denver for a business trip and was receiving instrument flight instruction from the CFI during the trip as part of the Pilot Mentor Program.
The pilots' initial departure airport on the day of the accident was in Kearney, Nebraska. They departed the Kearney Regional Airport (EAR) at 0804 cst and flew to the Sterling Municipal Airport (STK), Sterling, Colorado where they landed at 0832 mountain standard time (mst). They departed STK at 0907 mst en route to APA where they landed at 0956 mst. Fixed base operator (FBO) personnel at APA reported the pilots requested that the airplane be "topped" off with fuel. The pilots then left the airport in a rental car and returned later in the day. FBO personnel reported that they did not notice anything unusual with either the pilots or the airplane.
At 1305 mst, the pilots received a weather briefing through the CSC Direct User Access Terminal Service (DUATS) for a flight from APA to the Quincy Regional Airport (UIN), Quincy, Illinois. At 1349 mst, the CFI contacted the Prescott Contracted Flight Service Station and requested to cancel a previously filed flight plan to UIN, and to file a new flight plan to IRK. The CFI stated they were going back to Wisconsin, but were going to stop at IRK for fuel. The CFI reported they had 6 hours of fuel on board for the 3 hour 45 minute flight. The briefer asked if he wanted a weather briefing, adverse weather information, or notice to airmen information and the instructor replied "no" and that he had been looking at those all morning. The airplane departed APA at 1443 mst en route to IRK.
Radar data indicated the airplane flew a direct route from APA to IRK. The airplane was in contact with the Kansas City Air Route Traffic Control Center when they were cleared for the area navigation (RNAV) global positioning system (GPS) RWY 18 approach. The controller then cleared the airplane to switch to the common traffic advisory frequency at IRK. A FBO employee at IRK stated the pilot of N408DM checked in on the common frequency stating they were 7 miles from the airport and landing on runway 18. A second radio call was received from the airplane stating they were 5 miles away. The FBO employee radioed the wind and altimeter information to the airplane. The pilot did not reply, but had keyed the radio several times to turn on the pilot controlled airport lighting. When the airplane did not land, the FBO employee attempted to contact the airplane to no avail. Airport personnel then received a call from the Kansas City air traffic control center inquiring about the airplane. Local authorities searched for the airplane which was subsequently located about two hours later in a wooded area four miles north-northeast of the airport. The last radar contact was about .4 miles west of the initial tree impact at an altitude of 1,900 feet.
One witness who lived a half mile south of the accident site reported hearing an airplane near his house around 1900 and a short time later he heard a loud noise. This witness stated the engine sounded normal.
PERSONNEL INFORMATION
The CFI held a commercial pilot certificate with airplane single-engine land, multi-engine land, and instrument airplane ratings. His CFI certificate, which was renewed on May 18, 2012, contained airplane single-engine land, multi-engine land, and instrument airplane ratings. In addition, he held a ground instructor certificate with an advanced rating. The CFI held a Federal Aviation Administration (FAA) second-class medical certificate issued on July 16, 2013. The medical certificate contained the limitations "Must have available glasses for near vision. Not valid for any class after 1/31/2014."
The CFI's most current logbook was marked as "Book 6" and it contained entries from July 5, 2013, through October 22, 2013. The instructor's total flight time was 10,367.5 hours. The logbook contained 10 flights in the accident airplane totaling 19.1 hours of flight time. The instructor's actual instrument flight time was listed as 359.3 hours and his simulated instrument time was 134.9 hours. The instructor's last flight review was on October 24, 2013.
The private pilot was issued his private pilot certificate with an airplane single-engine land rating on September 23, 2011. He was issued a FAA third-class medical certificate on September 30, 2013. The medical certificate contained the restriction that the pilot must have glasses available for near vision.
The private pilot's logbook was not located during the investigation. On the application for his last medical certificate, the pilot reported having 365 hours of total flight time with 55 hours of that time having been flown in the last 6 months. The CFI's last logbook contained information for a flight on October 7, 2013, in the accident airplane. The remarks for this entry contained the private pilot's name along with the annotation "BFR" indicating the private pilot had a flight review on that date. There were no other remarks containing the private pilot's name in the CFI's logbook dated July 5, 2013, through October 22, 2013.
According to Wisconsin Aviation, the private pilot had been receiving instrument flight instruction from the accident CFI; however, it is unknown how much instruction he had received.

WRECKAGE AND IMPACT INFORMATION
The wreckage was located about 3.5 miles north of IRK. The terrain elevation at the initial tree impact was about 925 feet. The airplane initially contacted a 70 foot tall tree on the upslope side of a rolling hill. The airplane continued up the hill, over the crest of the hill, and down the other side of the heavily wooded hill, prior to coming to rest. The total wreckage path was about 790 feet long. The outboard sections of both wings were located near the initial tree impact followed by the right aileron and an inboard section of the right wing. Sections of the wings, empennage, and fuselage were scattered along the wreckage path. The first visible impact with the ground was located outside of the wooded area between two wooden power poles. The main portion of the fuselage came to rest inverted at the edge of a bean field. The airplane traveled about 650 f...
