Milwaukee

On June 4, 2007, about 1600 central daylight time, a Cessna Citation 550, N550BP, impacted Lake Michigan shortly after departure from General Mitchell International Airport, Milwaukee, Wisconsin (MKE). The two pilots and four passengers were killed, and the airplane was destroyed. The airplane was being operated by Marlin Air under the provisions of 14 Code of Federal Regulations Part 135 and departed MKE about 1557 with an intended destination of Willow Run Airport, near Ypsilanti, Michigan. At the time of the accident flight, marginal visual meteorological conditions prevailed at the surface, and instrument meteorological conditions prevailed aloft; the flight operated on an instrument flight rules flight plan.

During flight, the pilot reported shutting down the left engine due to a loss of oil pressure. He declared an emergency and diverted toward an alternate airport. However, while diverting, radar and radio contact were lost, and the airplane crashed. The wreckage path covered a distance of approximately 60 feet; the descent angle during impact was estimated to be about 45°. Oil was found behind the left engine, on the left flap, on the bottom of the left horizontal stabilizer, and on the bottom of the fuselage. Also, fuel stains were seen in the grass around the airplane. No preimpact fire indications were found. The pilot had reported low oil pressure in the left engine before the accident flight, and purchased seven quarts of oil before departing. No indications of power at impact were seen on either engine or propeller. Numerous abnormalities existed with the left engine. No discrepancies were noted with the right engine. The farmer who found the wreckage reported that sleet was falling at the time of the accident. The pilot of another aircraft reported structural icing conditions.

N81589 was following a Boeing 727 on ILS approach in IFR conditions. Approximately 2.5 miles from runway, N81589 suddenly deviated left nearly 90°. 39 seconds later, pilot reported he encountered severe turbulences, then said he was trying to climb. N81589 subsequently flew thru tree tops on rising terrain for approximately 2 city blocks, then hit power lines and a pole and crashed against a tree. No evidence of turbulences due to weather at/near approach altitude. Investigation showed 4.7 miles separation between aircraft when the 727 passed the point of deviation (pod). At pod, the 727 was on the ILS glide slope at 850 feet; N81589's altitude was not determined. Wind was from 120° at 3 to 6 knots, shifting more southerly withalt. Prevailing visibility was 1/2 mile; RVR for runway 12L was 6,000 feet; light rime icing was reported. Witnesses heard power interruption of one engine at pod; but there was no indication of power loss where aircraft hit trees. Radar data showed aircraft slowed to 80 knots at pod, accelerated to 100 knots during deviation, slowed to 70 knots before impact; vmca was 74 knots. Safety board believes the pilot most likely lost control due to slow speed and light airframe icing; possibly encountered wake turbulences. No reason found for loss of engine power. All seven occupants were killed.

Midwest Express Airlines Flight 206, DC-9 N100ME arrived at Milwaukee (MKE) at 13:15 on September 6, 1985. It departed Milwaukee at 13:36 and arrived in Madison at 13:55 after an uneventful flight. At Madison, N100ME was designated as flight 105 to Atlanta (ATL), with an intermediate stop in Milwaukee. Flight 105 departed Madison at 14:25 and arrived at Milwaukee, on time and without incident, at 14:41. About 14:49, the first officer of flight 105 contacted Milwaukee Tower to request an instrument flight rule (IFR) clearance to Atlanta. The clearance was received. The Atlanta forecast included a 1,000-foot ceiling, visibility 2 miles, thunderstorms and rain showers. At 15:12, the Before Engine Start Checklist was read and accomplished in accordance with Midwest Express operating procedures. Engine start was commenced at 15:14 and the After Start Checklist was accomplished. The first officer requested clearance to taxi to runway 19R for departure. About 15:17:50, the Taxi Checklist was completed, and the engine pressure ratio (EPR) and airspeed reference bugs were set to 1.91 and 133 knots, respectively. Both indications were correct for the departure conditions applicable to flight 105. At the conclusion of the Taxi Checklist, the captain advised the first officer "Standard briefing ..." At 15:19:15, the first officer reported to the tower local controller, "Milwaukee, Midex 105, ready on 19R." Flight 105 was cleared to "position and hold" on runway 19R. The captain called for the Before Takeoff Checklist, which was completed in accordance with the COM. Flight 105 was cleared for takeoff at 15:20:28; the first officer acknowledged the clearance. The captain operated the flight controls, and the first officer handled radio communications and other copilot responsibilities during the takeoff. The Midwest Express DC-9 Flight Operations Manual required the use of standard noise abatement takeoff procedures during all line operations, unless precluded by safety considerations or special noise abatement procedures. At the time flight 105 departed, noise abatement procedures were in effect. Midwest Express also utilized "reduced thrust" takeoff procedures (at the captain's discretion) to extend engine life. The flightcrew was complying with the reduced thrust and standard noise abatement takeoff procedures. The takeoff roll and liftoff were normal, with liftoff occurring near the intersection of the midfield taxiway and runway 19R, about 4,200 feet from the start of the takeoff roll. Rotation to the takeoff attitude occurred at 140 knots. The DC-9 accelerated to 168 knots with a rate of climb of about 3,000 feet/minute, indicating a normal two-engine initial takeoff flightpath. At 15:21:26 N100ME was about 7,600 feet down the runway, reaching a height of 450 feet above the ground. At that moment there was a loud noise and a noticeable decrease in engine sound. The captain then remarked "What the # was that?" The first officer did not respond. At 15:21:29, the local controller transmitted, "Midex 105, turn left heading 175." At the time of his transmission he observed smoke and flame emanating from the right airplane engine. The captain asked the first officer, "What do we got here, Bill?" The first officer did not respond to the captain but advised the local controller, "Midex 105, roger, we've got an emergency here." Two seconds later, the captain said, "Here"; again there was no response. Neither pilot made the call outs for "Max Power" or "Ignition Override-Check Fuel System," which were part of the Midwest Express "Engine Failure after V1" emergency procedure. Meanwhile the airplane began to deviate substantially to the right and the heading changed from 194 degrees to 260 degrees in eight seconds. The vertical acceleration dropped sharply to about 0.3 G and increased to a value of 1.8 G. At that point the airplane stalled. This accelerated stall occurred at a KIAS of about 156 kts.

En route, the crew encountered engine problems and was cleared to divert to Ashland Airport. While descending in marginal weather conditions (low ceiling, fog and icing conditions), the crew lost control of the airplane that crashed in a field located in Greenup, west of the airport. The aircraft was destroyed and all three occupants were killed. At the time of the accident, weather conditions were below minimums.

While parked at Wausau Airport, the engine was started when the airplane departed its parking place, rolled for few yards and eventually collided with a tree. The pilot who was not on board was uninjured while the aircraft was damaged beyond repair.

While flying over Lake Michigan on a flight from Detroit to Milwaukee, the twin engine airplane went out of control and crashed into Lake Michigan, few miles off Milwaukee. The plane wreckage and the pilot's body were never found.

On approach to Milwaukee Airport, the pilot encountered poor weather conditions with limited visibility due to fog. He continued the descent and passed below the MDA when the airplane struck trees and crashed in a wooded area located 5,7 miles short of runway. A passenger was killed while three other occupants were injured. The aircraft was destroyed.

While descending into the traffic pattern to Waukesha Airport, at an altitude of 800 feet, the Cessna 402 collided with a Cessna 150 registered N6175G with two people on board. Following the collision, both aircraft dove into the ground and crashed in flames in a field. All three occupants were killed.

The twin engine aircraft departed Kenora, Ontario, on a flight to Milwaukee with an intermediate stop at International Falls Airport, carrying eight passengers and a pilot. En route, both engines failed and the pilot was vectored to Watertown Airport for an emergency landing. On approach, he realized we would not make it so he raised the landing gear and completed a belly landing in a field. The airplane slid for dozen yards and came to rest. All nine occupants were seriously injured and the aircraft was damaged beyond repair.
