The pilot was not current for operations in instrument meteorological conditions.

Factual Information

HISTORY OF FLIGHT On October 24, 2000, at 2010 eastern daylight time (edt), a Piper PA-28R-200, N15900, owned and piloted by a private pilot, was destroyed during an in-flight collision with trees and subsequent collision with terrain while executing the Instrument Landing System (ILS) runway 9 approach to the Otsego County Airport (GLR), Gaylord, Michigan. Instrument meteorological conditions prevailed at the time of the accident. The business flight was operating under the provisions of 14 CFR Part 91 on an instrument flight plan. The pilot and his single passenger were fatally injured. The flight departed the Gerald R. Ford International Airport, Grand Rapids, Michigan, at 1856. According to a Federal Aviation Administration (FAA) Air Traffic Control (ATC) accident report, the accident airplane was issued vectors to intercept the final approach course for the ILS runway 9 approach to GLR. The accident airplane was cleared for the ILS runway 9 approach and the pilot was instructed to cancel his flight plan through another airplane, a Piper Navajo (N59815), which was holding at the Gaylord VHF omni-directional range/distance measuring equipment (GLR VOR/DME). The GLR VOR/DME is located within the airport's perimeter and provides navigation assistance for visual and instrument flight operations. Aircraft radar track data for the period before and after the reported accident time was obtained from the FAA. The aircraft radar track data was plotted using commercial software. The plot is appended to this factual report along with a copy of the source data. According to the supplied radar track data, the accident airplane's first radar return was a reinforced discrete beacon code 12.235 nautical miles (nm) southwest of GLR at 2001:29 (hhmm:ss). The radar track data indicated the airplane continued heading north until 2005:05 when a right turn was initiated. The last radar return was recorded 7.631 nm west of GLR. The wreckage was located approximately 3 nm west-northwest of GLR. PERSONNEL INFORMATION The pilot held a private pilot certificate with ratings for airplane single engine land and instrument airplane operations. The pilot's last medical examination was conducted on June 16, 1999, and he was issued a third-class medical certificate with the limitation, "Must wear corrective lenses."

COMMUNICATIONS The voice transmissions between the accident aircraft (N15900), Minneapolis Air Route Traffic Control Center (ZMP-ARTCC), and the holding airplane (N59815) were transcribed in part as follows: 1951:22 (hhmm:ss) ZMP-ARTCC: november one five niner zero zero descend maintain three thousand five hundred 1951:25 N15900: out of six three point five nine zero zero 1951 1952 1953 1954 1955 1956 1957 1957:01 ZMP-ARTCC: november one five niner zero zero turn further ten degree left 1957:06 N15900: ten degrees left nine zero zero 1957:40 ZMP-ARTCC: november one five niner zero zero maintain three thousand two hundred please 1957:46 N15900: three point two nine zero zero 1957:49 ZMP-ARTCC: and what is your new heading going to be once your turn further left 1957:52 N15900: fifteen degrees nine zero zero 1957:52 ZMP-ARTCC: okay make the heading of zero zero five please for nine zero zero 1957:51 N15900: zero zero five nine zero zero 1958 1959 2000 2001 2002 2003 2004 2004:38 ZMP-ARTCC: november one five niner niner zero zero you're three from bangu right heading zero six zero maintain three thousand two hundred until established on localizer cleared i l s nine approach to gaylord airport 2004:48 N15900: okay zero three zero ah cleared on the i l s zero niner Gaylord three thousand until established nine zero zero 2004:54 ZMP-ARTCC: november nine zero zero fly heading zero six zero and ah cleared for approach 2004:59 N15900: zero six zero niner zero zero 2005 2005:37 ZMP-ARTCC: november one five niner zero zero change to advisory frequency is approved and try and cancel through a five niner eight one five he's right on top of you ah outbound in the holding 2005:53 ZMP-ARTCC: november niner zero zero change to advisory frequency approved relay your down time through a ah five niner eight one five if I don't hear ya he's above waiting to get in 2006:00 N15900: yeah we got him in sight we'll stay with you for a bit nine zero zero 2007 2008 2009 2010 2011 2012 2012:06 ZMP-ARTCC: november eight one five did you hear from nine zero zero yet he should be ah should be touching down any second 2012:11 N59815: negative i haven't heard anything from him 2013 2014 2014:41 ZMP-ARTCC: november eight one five wanta go over to unicom real quick and see if one five niner zero zero is on the ground he should be down by now 2014:46 N59815: alright stand by one 2015 2016 2016:33 ZMP-ARTCC: november eight one five did you hear from him at all 2016:44 N59815: eight one five negative ah unicom hadn't from him either 2016:47 ZMP-ARTCC: okay he should have been down a couple of minutes ago expect further clearance at zero zero two five [2025 edt] now for november five niner eight one five 2016:54 N59815: zero zero two five eight one five 2017 2018 2018:18 ZMP-ARTCC: november eight one five unicom hadn't heard from him at all if you would go back over to frequency ah over to Unicom there and see if they can ah scare him up otherwise we'll have our guys um call and see if we can find him here and expect further clearance at ah zero zero four zero [2040 edt] now 2018:34 N59815: okay further clearance zero zero four zero and we'll call unicom again 2018:37 ZMP-ARTCC: okay thanks 2019 2019:41 N59815: minneapolis center navajo five niner eight one five 2019:43 ZMP-ARTCC: november eight one five go ahead 2019:45 N59815: yeah unicom still hadn't heard anything from this guy ah they said they said they had one guy that ah thought they ah might of heard him call but ah they can't confirm whether he's on the ground nobody's seen him 2019:56 ZMP-ARTCC: okay ah very good we have our people calling up there right now as well but ah he should a he he understood that he was supposed to relay through you so ah i'm starting to get a little concerned about where he is so well keep calling in if you hear anything in the interim let me know 2020:09 N59815: ya we'll do we may not be able to get in here anyway so we'll let you know what the plan is The entire ATC transcript is appended to this factual report. A review of the certified rerecording of the voice transmissions shows that ZMP-ARTCC did not issue the current weather conditions to the pilot or verify that the pilot had the current weather conditions prior to issuing the clearance for the ILS runway 9 approach. WRECKAGE AND IMPACT INFORMATION The wreckage was located in a heavily wooded planned forest of pine-trees near the city of Gaylord, Michigan. A global positioning system (GPS) receiver recorded the position of the main wreckage as 45-degrees 01-minutes 31.02-seconds north latitude, 84-degrees 46-minutes 17.58-seconds west longitude. The initial impact was at 45-degrees 01-minutes 29.52-seconds north latitude, 84-degrees 46-minutes 20.82-seconds west longitude. The wreckage was located 0.66 nautical miles (nm) left of the ILS runway 9 course centerline and 2.44 nm from the runway threshold. All major airframe components were located along a debris field that was approximately 280 feet in length and orientated on a 070 degree magnetic heading. Along the debris field there were multiple portions of severed tree material. The fuselage was resting against a tree and was canted approximately 35 degrees to the left. The main cabin and instrument panel was destroyed. The nose landing gear was in an extended position. Both main landing gear were separated from their respective wings and were located along the wreckage debris field. Both wings were separated from the fuselage and found along the wreckage debris field. The upper skins of both wings had semicircular crush marks that were oriented along the wing's chordline. The semicircular crush marks were the same average diameter as trees near the location of the accident. Aileron control continuity could not be established due to damage. All aileron control cable breaks were consistent with tension overload. The vertical stabilizer remained attached to the fuselage and the rudder remained partially attached to the vertical stabilizer. The right side of the horizontal stabilator remained attached to the fuselage. The left side of the horizontal stabilator was separated from the fuselage at the root. The leading edge of the entire horizontal stabilator had semicircular crush marks that were perpendicular to the leading edge. Horizontal stabilator and rudder control cable continuity was established from the control surfaces to the main cabin. The engine remained partially attached to the airframe and was bent approximately 45 degrees to the left. Engine crankshaft and valve train continuity was established by rotating the crankshaft through the accessory gear section. There was thumb compression on all cylinders. There was fuel in the fuel flow divider and the fuel line leading to the fuel flow divider. The left magneto produced spark on all leads when the engine crankshaft was rotated. The right magneto produced spark on all leads when rotated by hand. The vacuum pump was removed and disassembled. The vacuum pump drive and vanes were intact. The propeller was separated from the engine. The propeller blades had chordwise scratching, leading edge damage, and S-shape bending. No anomalies were found with the airframe, flight controls, propeller, and engine that could be associated with a pre-impact condition. MEDICAL AND PATHOLOGICAL INFORMATION An autopsy was performed on the pilot at the Nelson Funeral Home, Gaylord, Michigan, on October 25, 2000. A Forensic Toxicology Fatal Accident Report was prepared by the FAA Civil Aeromedical Institute, Oklahoma City, Oklahoma. The toxicology results for the pilot were: * No Ethanol detected in Urine * No Drugs detected in Urine TESTS AND RESEARCH The avionics from the accident airplane were removed and bench tested. The VOR/Localizer/Glideslope Indicator was operational. The localizer function was within calibration specifications. The glide slope function indicated one-dot high with a centered signal input. The VOR/Localizer Indicator was operational. The localizer function was within calibration specifications. The VOR function had a 6 degree error. Both Nav/Com receivers were operational. The marker beacon receiver was operational and was within specifications. The automatic direction finder was operational. The DME system was operational. ADDITIONAL INFORMATION According to 14 CFR Part 61.56, "Flight Review": (c) Except as provided in paragraphs (d), (e), and (g) of this section, no person may act as pilot in command of an aircraft unless, since the beginning of the 24th calendar month before the month in which that pilot acts as pilot in command, that person has - (1) Accomplished a flight review given in an aircraft for which that pilot is rated by an authorized instructor; and (2) A logbook endorsed from an authorized instructor who gave the review certifying that the person has satisfactorily completed the review. According to 14 CFR Part 61.57, "Recent Flight Experience - Pilot-In-Command": (c) Instrument Experience: Except as provided in paragraph (e) of this section, no person may act as pilot in command under IFR or in weather conditions less than the minimums prescribed for VFR, unless within the pr

Probable Cause and Findings

The pilot not maintaining proper glideslope and localizer alignment during the precision instrument approach, the pilot continuing flight below the decision height, the pilot not performing a missed approach, and the pilot not maintaining altitude/clearance from the trees and terrain. Contributing factors to the accident were the air traffic controller not issuing the current weather conditions to the pilot prior to the approach clearance, the weather conditions being below the instrument approach landing minimums, the pilot's lack of recent experience in instrument flight rules (IFR) operations and the pilot disregarding federal regulations regarding instrument currency.
