## Narrative

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

NTSB PRELIMINARY TRACK DATA INDICATED THE AIRPLANE AT AN ALTITUDE OF 7,000 FT MSL AND AN ESTIMATED GROUND SPEED OF 77 KNOTS. FROM THAT POINT, THE TRACK MADE A SHARP 90 RIGHT-TURN AND CONTINUED ON A 305 HEADING FOR ABOUT 3,020 FT OVER A DURATION OF ABOUT 20 SECONDS. THE TRACK THEN MADE ANOTHER SHARP 90 RIGHT-TURN AND AFTER ABOUT 880 FT AND THE LAST RECORDED TRACK DATA INDICATED AN ESTIMATED GROUND SPEED OF 117 KNOTS. THE ACCIDENT SITE WAS LOCATED ABOUT 740 FT SOUTHWEST OF THE LAST RECORDED TRACK DATA.

BASED ON THE INFORMATION AVAILABLE AT THIS TIME, A DETERMINATION OF WHICH OF THE FAA'S 9 RESPONSIBILITIES MAY BE FACTORS IS INCONCLUSIVE.  THIS FAA INVESTIGATION WILL CONTINUE AND THIS REPORT WILL BE AMENDED WHEN MORE INFORMATION BECOMES AVAILABLE.
