The Kalitta Air jet took off from O'Hare International Airport in
Chicago late Wednesday. It later reported mechanical problems in one
of Its engines, a Federal Aviation Administration spokeswoman in
Chicago said. The Boeing 747 was able to fly, but was diverted as a
safety precaution to Detroit, where it landed without incident, FAA
officials said. No one was injured.
After the landing, airline personnel discovered the engine was
completely gone, FAA officials said.
Michigan authorities searched Thursday for the engine, which may have
fallen into Lake Michigan, the FAA said. The FAA will Investigate the
incident, but the results of an investigation could take weeks.

On October 20, 2004, about 2029 central daylight time, a Boeing 747-132,
N709CK, operated by Kalitta Air, LLC, as flight 825, received substantial
damage following a separation and loss of the number one engine while
climbing through about 16,000 feet mean sea level over Lake Michigan. The
14 CFR Part 121 non-scheduled international cargo flight was operating on
an instrument rules flight plan. Night visual meteorological conditions
were reported at the time of the accident. The two pilots, one flight
engineer, and two flight mechanics were uninjured. The flight departed from
Chicago O'Hare International Airport, Chicago, Illinois, at 2010, and was
en route to John F. Kennedy International Airport, New York, New York, when
it diverted to Detroit Metropolitan Wayne County Airport (DTW), Detroit,
Michigan, where it landed without further incident.

The flight crew did not report any abnormal conditions prior to the engine
separation. Following the engine separation, the flight crew diverted to
DTW where a landing was accomplished with normal operation of the leading
edge devices and trailing edge flaps.

On-scene inspection of the airplane revealed engine separation at the
forward engine mount bulkhead and at the aft engine mount. The aft engine
mount was intact with a section of the engine turbine exhaust case still
attached. The pylon remained attached to the wing, and the pylon alignment
marks were in alignment. The area around the forward engine mount bulkhead
was deformed in the outboard and upward direction.

Radar data estimates indicate that the engine is in an area of Lake
Michigan that is approximately 240 feet deep.
