# NTSB CHI00LA291: Beech A36TC, N3683D, Moorehead, MN, September 9, 2000 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: September 9, 2000, 14:00 local (19:00 UTC) - Place: Moorehead, MN - Coordinates: 46.859455, -96.74932 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=46.8595&lon=-96.7493&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report October 17, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 51074 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI00LA291 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/51074/pdf - Page: https://openairdocs.org/ntsb/CHI00LA291 ## Probable cause The pilots failure to abort the takeoff and the airplane not attaining a proper climb rate for undetermined reasons. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, takeoff - roll/run - aborted takeoff - not performed, pilot in command (cause) - proper climb rate - not attained (cause) - reason for occurrence undetermined (cause) ## Analysis The airplane impacted a road after takeoff. Witnesses reported that the aircraft became airborne just before reaching the end of the 4,000 foot long runway and only achieved an altitude of a few feet. The airplane settled back to the ground and then impacted a road before coming to rest in a farm field. No anomalies were found with respect to the airframe. A teardown inspection of the engine and its accessories failed to reveal any anomalies that would have prevented normal engine operation. The pilot said that he recalled the start of the takeoff but had, "... no further memory of the event due to injury." The takeoff was made on runway 12 and the reported weather was: Wind 190 degrees magnetic at 15 knots gusting to 21 knots; Visibility 10 statute miles; Sky condition clear; Temperature 29 degrees Celsius; Dewpoint 16 degrees Celsius; Altimeter setting 29.32 inches of Mercury. According to the aircraft performance charts, the reported weather, and a maximum gross weight of 3,650 pounds, the takeoff ground roll should have been about 1,500 feet. ## Factual narrative On September 9, 2000, at 1400 central daylight time, a Beech A36TC, N3683D, piloted by a private pilot, sustained substantial damage during a collision with terrain on takeoff from runway 12 (4,000 feet by 75 feet, dry asphalt) at the Moorhead Municipal Airport, Moorhead, Minnesota. The 14 CFR Part 91 personal flight was not on a flight plan. Visual meteorological conditions prevailed at the time of the accident. The pilot, who was the sole occupant, was seriously injured. The flight was originating at the time of the accident and was en route to Saint Paul, Minnesota. A Federal Aviation Administration inspector found tire marks in the grass that began about 50 feet from the departure end of runway 12 and continued to the accident site. In a written statement, the pilot said that he recalled the start of the takeoff but had, "... no further memory of the event due to injury." A witness stated, "... when I saw the bonanza it was on approximately the last 1000' of runway 12 with the main wheels on the runway and the nosewheel off the runway. Just before reaching the end of runway 12 the aircraft became airborn[e] and flew with the main wheels 1-2 feet off the grass overrun area. The main wheels touched the ground for a couple hundred [feet] before the aircraft became airborn[e] again. The aircraft flew for a few seconds, pitched up radically before pitching down to a near nose level attitude before the three wheels touched the ground. The aircraft rolled a short distance before impacting [the road]..." In a telephone interview, the witness stated that he noticed that the flaps were extended. A second witness stated, "I observed the plane approx[imately] 1000' from [the] end of [runway] 12 in a tail low attitude. [The airplane] seemed to be flying slow and mushing. The plane touched down approx[imately] 200/300' past the end of the runway in the grass. Bounced up into the air for another 300 to 400 feet and then settled back into a bean field..." Another witness said that the aircraft went by the departure end of the runway at about 1-1/2 feet off of the ground. He said that the wheels then hit the ground and the aircraft subsequently impacted the road and came to rest in a ditch on the other side of the road. A postaccident examination of the accident aircraft was conducted. With respect to the airframe, no anomalies were detected that could be associated with a preexisting condition. The flap actuator extension was measured as 5.88 inches, which corresponds to approximately 25 degrees of flap extension. The A36TC flap system has three settings, 0, 15, and 30 degrees with no intermediate settings. The Pilot's Operating Handbook for the aircraft lists 0 or 15 degrees of flap extension as allowable settings for takeoff. The aircraft engine was removed and transported to the Teledyne Continental Motors facility in Mobile, Alabama where a teardown inspection was performed under the direct supervision of an NTSB investigator. The teardown inspection of the engine and its accessories failed to reveal any anomalies that would have prevented normal engine operation. Aircraft takeoff performance charts indicating takeoff ground roll distance as a function of temperature, pressure altitude, aircraft weight, and wind component are appended to this report. The weather reporting station located at the accident airport recorded the weather at 1355 local time as: Wind 190 degrees magnetic at 15 knots gusting to 21 knots; Visibility 10 statute miles; Sky condition clear; Temperature 29 degrees Celsius; Dewpoint 16 degrees Celsius; Altimeter setting 29.32 inches of Mercury. Based on the recorded weather and the airport field elevation of 917 feet MSL, the density altitude was determined to be 3,534 feet. ## Aircraft - Registration: [N3683D](https://openairdocs.org/deregistered/N3683D-2003-05-15), registration cancelled 2003-05-15, S/N EA-112, built 1980 (OpenAirDocs) - Reported make and model: Beech A36TC - Registry model: [Beech A36TC](https://openairdocs.org/model/beech-a36tc) (registry code 1151603) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: EA-112 - Airframe hours: 3369 - Engines: Continental TSIO-520-UB 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Landmark Aviation LLC. - Airworthiness certificate: Standard, Utility - Last inspection: Annual, January 26, 2000, 146 hours before - Departed: JKJ - Destination: SAINT PAUL, MN - Airport: JKJ, Moorhead Municipal Arpt, runway 12, 4,000 × 75 ft, asphalt ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
