About 2050 on March 13, 1986, Simmons Airlines flight 1746, an Embraer Bandeirante, EMB-110P1, operating as a regularly scheduled flight, departed the Detroit Metropolitan Airport en route to Sault Ste Marie, Michigan, with a stop in Alpena, Michigan. The en route portion of the flight to Alpena was uneventful. However, due to the prevailing instrument meteorological conditions, the crew was unable to complete the instrument landing system (ILS) approach and land and they declared a missed approach at 2142. At 2153, the flight was cleared for a second ILS approach to Alpena. At 2156, the crew acknowledged that radar services were being terminated. This was the last transmission from the airplane. About 2215, a motorist reported that the airplane had
crashed. The airplane was found in a wooded area about 300 feet to the left of the extended centerline, and 1 1/2 miles short of the threshold of runway 01 at Alpena. The airplane was destroyed and two of the seven passengers and one of the two crewmembers onboard were killed.

The two commercial rated pilots were returning from a part 135 flight at night. The fuel tanks were inadvertently not switched from mains to auxiliary. Fuel starvation occurred when aircraft was at low altitude. Insufficient altitude remained to restart the engines. Aircraft impacted ground. A post accident fire erupted destroying the aircraft. Both pilots were seriously injured.

Evidence shows copilot called, 'mayday, uncontrolled spin' after aIRCRAFT radar track showed decelERATION from 180 to 120 kNOts over 2 minUTES period while maintaining constant 4,000 feet cruise altitude. Constant altitude consistent with autopilot/autotrim use, particularly in view of reported turbulence/icing. Elevator trim found at approx 13° nose up. No evidence found of preimpact failure or malfunction in aircraft powerplants, structure or systems. Evidence suggests scenario of crew inattention after power reduction with autopilot altitude setting. On power application, aircraft pitched up from slow speed into uncontrolled flight. Duty day at time of mishap approaching 11 hours. All five occupants were killed.

The crew was engaged in a military exercise consisting of an aerial attack of a US Navy vessel. In unknown circumstances, the aircraft collided with a second Flight International Learjet 35 registered N39DM. Both aircraft crashed in the sea about 27 miles southeast of San Clemente Island and all four crew members were killed.

As the aircraft was climbing thru 19,000 feet at night, the #2 generator (gen) light came on. The flight crew noted there was no output from the #2 gen and it would not reset. They then checked the #1 gen voltage and noted it was 14 to 15 volts. The crew reduced the electrical load; however, about 5 minutes later, the batteries became discharged and there was a total loss of electrical power. Using a flashlight, the crew diverted to the Chester County Airport which had a 4,600 feet runway. The gear was extended with the emergency system. The elevator trim was inoperative, so both pilots applied back pressure on the yoke to overcome the nose down tendency. After landing about 1/4 of the way down the runway, the crew tried to use the thrust reversers, but the reversers were inoperative. Subsequently, the aircraft continued off the side and beyond the end of the runway, hit a wooden beam and a snowbank, then came to rest in a ditch. An investigation revealed a shaft failure of the #2 gen (starter/gen) and worn brushes in the #1 gen. With total electrical failure, the following were also inoperative: wing flaps, anti-skid, capt's airspeed indicator and altimeter, nose wheel steering, cockpit lighting.

The aircraft impacted the ground about 1,000 feet to the left of the runway. The pilot stated that he did not have visual contact with the ground and remembers attempting to make a missed approach. Conditions were IMC. The pilot was seriously injured and the aircraft was destroyed.

The pilot was alerted at 0100 for 0200 flight from Kenosha to Milwaukee, WI to pick up cargo for a flight to Atlanta, GA. At 0310, the aircraft departed Milwaukee in VFR. En route, the pilot obtained weather and an IFR clearance. Some of his radio transmissions were not standard. At 0433, he complied with ATC request for frequency change, but his radio transmissions were not clear. Approximately 5 minutes later, ATC asked the pilot to change frequency again, but 5 calls were made before he replied. His last transmission was at 0445:48; he didn't respond to further ATC calls. The aircraft continued cruising at 11,000 feet until 0621, then it descended without clearance. Radar contact was lost at 0627 cst (0727 est). Shortly thereafter, it impacted trees on a mountain, then crashed to the ground and burned. A witness believed the engines were throttled back before impact. Also, the witness reported low clouds and fog, but said the mountain was visible and was not obscured. The pilot had a 1,58‰ alcohol level in blood, no sleep for 21.5 hours, history of alcohol abuse, 7 prior dwi convictions (and ndr rec). Also, he falsified FAA medical applications. FAA was advised in 1984, but took no action.

During arrival, the crew of USAir flight 499 landed on runway 24, which was covered with snow. Reportedly, while landing, the aircraft touched down approximately 1,800 to 2,000 feet beyond the displaced threshold. Altho armed, the spoilers did not autodeploy, so the captain operated them manually. He lowered the aircraft's nose, actuated reverse thrust and applied brakes. The brakes were not effective. Subsequently, the aircraft continued off the end of the runway, ran over a runway end id light, struck a fence and came to rest straddling a road. The crew had planned on making an ILS approach to runway 06, but the RVR was only 2,800 feet and a minimum RVR of 4 000 feet was requested for that runway. The crew elected to land on runway 24, since 1/2 mile visibility was sufficient for that runway. However, the approach was made with a qtrg tailwind and approximately 10 knots above Vref. Tailwind landings were not authorized on runway 24 in wet/slippery conditions. The runway braking action was reported as fair-to-poor. The pilot's handbook cautioned the crew to monitor the spoilers when landing on slippery runways, since the spoilers auto-deploy only with wheel spin-up or when the nose wheel is on the ground. A passenger was slightly injured while 22 other occupants were uninjured.

On February 17, 1986 the wreckage of N7EA along with the skeletal remains of two persons were found. The aircraft crashed into trees causing the separation of the outboard six feet of left wing and then continued crashing through more trees before colliding with the ground. The aircraft caught fire during the impact sequence and was completely destroyed by post crash fire. Fuel fittings and pumps used in aircraft fuel systems were found in the cabin area of the wreckage. Also the closure mechanisms for several military type duffle bags were found and only two seats were installed in the cockpit. Examination of the engines revealed both to be operable at the time of the accident. The date and time of the accident could not be determined. The origin and destination of the flight could also not be determined. The aircraft was last seen at the Fort Lauderdale-Executive Airport on 2/3/86.
