Accident Number: CEN20LA028
Date & Time: 12/03/2019, 0833 EST

Flight Conducted Under: Part 135: Air Taxi & Commuter - Non-scheduled 

On December 3, 2019, about 0833 eastern standard time, a BAE 125 800A airplane, N469RJ, impacted terrain during an instrument landing system (ILS) approach to runway 33 at the Coleman A. Young Municipal Airport (DET), near Detroit, Michigan. The airline transport pilot and copilot were uninjured, and the airplane's right wing sustained substantial damage. The airplane was registered to and operated by Business Jet Managers Inc. as a Title 14 Code of Federal Regulations Part 91 repositioning flight for a subsequent Part 135 flight. Day visual meteorological conditions prevailed in the area about the time of the accident, and the flight was operated on an instrument flight rules flight plan. The flight originated from the Willow Run Airport (YIP), near Detroit, Michigan, about 0819, and was destined for DET.

According to initial information from the pilot in command who was flying the accident airplane, the crew was conducting an ILS approach to runway 33. The airplane broke out of the clouds about 1,500 ft above ground level (AGL), and the airplane had picked up rime icing during the flight. The air traffic controller at YIP advised them of the icing conditions present. The airplane had a TKS [Tecalemit-Kilfrost-Sheepbridge Stokes] type weeping wing for deicing. Spots where the weeping wing panels joined had an ice build up. The airplane did not have any airspeed oscillations during the approach, and the crew maintained 140 knots on approach. The flight's calculated Vref speed was 128 knots. The pilot reported that the right wing "dropped" and a stall occurred. He said that there was no shaker activation during the flight.

According to initial information, about 0807, a BAE 125 800A airplane landed at DET. The pilot of that airplane stated that he was in his own airplane on the ramp waiting for passengers and witnessed another 800A exiting runway 33 traveling through the grass and across the taxiway coming to rest in the grass past the taxiway. His airplane's flight to DET lasted approximately 18 minutes. Before entering the clouds, the witness reported the TKS ice protection system, engine heat, and engine ignitions were turned on. The witness, in part, stated, "Soon afterwards our ice detected light came on. We were vectored at 3000 ft for the ILS 33. We reported light ice and outside air temperature was -9 C. ... Approximately 1000 ft AGL we broke out and landed visually. All operations were normal. Our landing weight was 22,500 lbs. We bugged the airspeed indicator for Ref 129 and approach 139. On final our airspeed varied from 134 to 140 knots. Our touchdown speed was approximately ref minus 8. After landing we had some minor ice on the wing leading edge. The small temperature probe had an umbrella shaped ice formation. The outboard ends of the horizontal stabilizer had the typical "T" ice formation on about the outer 9 inches of both horizontals."

DET, located approximately five miles northeast of downtown Detroit, Michigan, was a publicly owned, towered airport that was owned by the City of Detroit. It was continuously attended by air traffic control. DET's surveyed field elevation was 626 ft above mean sea level. DET was serviced by two runways, 7/25 and 15/33. Runway 7/25 was a 3,714 ft by 100 ft asphalt runway and runway 15/33 was a 5,090 ft by 100 ft, asphalt runway. Runway 15/33 was marked as a precision approach runway and was serviced by a four-light precision approach path indicator on the runway's left side. The airport had 4 published approaches, which included the ILS OR LOC RWY 33 approach.

The airplane was equipped with a magnetic tape cockpit voice recorder (CVR), Fairchild model A100A, serial number 58758, which was removed from the accident airplane and retained for readout and evaluation.

The airplane was equipped with a L3 Communications Avionics Systems, Inc. Landmark TAWS 8000 unit and two digital electronic engine control units. These units were removed from the accident airplane and retained for readout and evaluation.

DETROIT - A landing gear "mishap" caused a small plane to go off the runway at Detroit City Airport on Tuesday.

The Detroit Fire Department said a small plane experienced a 'mishap' with its landing gear while taxiing. The plane's nose landing gear collapsed, causing the plane to skid 50-60 feet off the runway.

The pilot and co-pilot were the only people aboard the plane at the time of the incident and did not need medical attention. The plane is a twin-jet aircraft.  

The engine was running, and sources say the controls and cable to turn the engine off were damaged. Meanwhile, 7,000 pounds of fuel were in the engine. Because of the potential danger, the Mobile gas station nearby had to shut off its gas line and was unable to sell any gas.

Flight officials say the used water on the plane and after a few hours, the engine finally stopped.

According to Flight Aware, the plane took off from Willow Run at 8:19 a.m. and was scheduled to land at KDEP at 8:34 a.m. The incident was reported around 8:40 a.m.. 

The city put out a statement:

"We received a quick response from Detroit Fire and EMS, which have the scene under control. At this time it does not appear runway conditions played any role in the incident. The National Transportation Safety Board and the FAA will conduct a joint investigation into the accident."

  1. This was a simple nose gear collapse. What could possibly have been damaged there riding the belly of the nose that could have damaged any engine controls that caused the crew to be incapable of shutting down that left engine? I am assuming the right engine was shut down inside the cockpit as the photo shows the firehose pointing the stream into the left engine.

    This is not the first time a running engine has happened after a crash. There was a Falcon 50 crash that went off the end of the runway and down an embankment. It broke in two and the middle engine kept running in full power as engine control wiring was severed. Then there was a Citation CJ2/M2 at Bader Field, Atlantic City, NJ (now closed). It landed long and hot with a 10 knot tail wind and went into the water. The engines initially shut down, but right after boaters rescued the crew and passengers, the left engine fired back up while it was in the water which appeared to be about 4 feet deep. It spun around in a slow half circle for a couple of minutes until finally shutting down on its own. The pilots failed to shut off the fuel valves in the cockpit, and the water caused a short circuit refiring the right engine. Video of that starts around 3:00 in this low quality video:

    I just don't see why this accident would cause an engine to fail to shut down based on the two examples above.

  2. Maybe need smart phone app to control engines

  3. ^^Hah on the smart phone/tablet app comment. That's actually not a bad idea for placing a wifi accessible final solution kill switch to jet engines.

    To CFI, no, it is not ruined. An expensive overhaul however, is another matter.
