## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON NOVEMBER 15, 2021, ABOUT 1245 EASTERN STANDARD TIME, A BEECH E-90, N290KA, WAS

DESTROYED WHEN IT WAS INVOLVED IN AN ACCIDENT NEAR BOYNE CITY, MICHIGAN. THE AIRLINE TRANSPORT

PILOT AND PASSENGER SUSTAINED FATAL INJURIES. THE AIRPLANE WAS OPERATED AS A TITLE 14 CODE OF

FEDERAL REGULATIONS PART 91 BUSINESS FLIGHT.

A REVIEW OF PRELIMINARY AIR TRAFFIC CONTROL (ATC) INFORMATION REVEALED THAT THE AIRPLANE

DEPARTED OAKLAND COUNTY INTERNATIONAL AIRPORT (PTK), PONTIAC, MICHIGAN, AT 1150 ON AN

INSTRUMENT FLIGHT RULES (IFR) FLIGHT PLAN AND CLIMBED TO 16,000 FT MEAN SEA LEVEL (MSL). THE

AIRPLANE WAS ENROUTE TO BOYNE CITY MUNICIPAL AIRPORT (N98), BOYNE CITY, MICHIGAN. THE

AIRPLANE DESCENDED TOWARD N98 AND THE PILOT WAS CLEARED FOR THE RNAV GPS RUNWAY 27

APPROACH.

WHILE ON THE FINAL APPROACH COURSE, THE AIRPLANE?S GROUNDSPEED GRADUALLY SLOWED FROM 129 TO

88 KNOTS OVER A PERIOD OF ONE MINUTE AND THE LAST RECORDED LOCATION SHOWED THE AIRPLANE WAS

3.3 NAUTICAL MILES EAST OF THE RUNWAY 27 THRESHOLD, ABOUT 1,500 FT MSL (800 FT ABOVE GROUND

LEVEL), AND SLIGHTLY LEFT OF THE APPROACH COURSE. THE AIRPLANE SUBSEQUENTLY IMPACTED THE GROUND

ABOUT 600 FT WEST OF THE LAST RECORDED LOCATION. BROKEN TREE LIMBS INDICATED THE AIRPLANE WAS IN

A STEEP DESCENT OF ABOUT 70° WHILE ON A WEST HEADING.

TWO WITNESSES LOCATED ABOUT ¼ MILE SOUTHEAST OF THE ACCIDENT SITE HEARD THE AIRPLANE FLY

OVERHEAD, FOLLOWED BY A LOUD THUD. THE WITNESSES OBSERVED VERY HEAVY SLEET WITH LOW VISIBILITY

CONDITIONS FOR ABOUT 10 MINUTES, BEFORE AND AFTER THE ACCIDENT TIME. THE SLEET HAD A HIGH LIQUID

CONTENT AND WOULD MELT QUICKLY AFTER GROUND IMPACT. AN AIRMAN?S METEOROLOGICAL INFORMATION

(AIRMET) FOR ICING WAS VALID FOR THE ACCIDENT LOCATION.

INITIAL EXAMINATION REVEALED THE ENTIRE AIRPLANE WAS PRESENT AT THE ACCIDENT SITE AND NO

ANOMALIES WERE NOTED WITH THE AIRPLANE?S FLIGHT CONTROLS THAT WOULD HAVE PRECLUDED NORMAL

OPERATION. THE AIRPLANE WAS RETAINED FOR FURTHER EXAMINATION.

## The NTSB's investigation of this event (1)

From the NTSB's public API. 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. Compare the reported make and model.
