A flight recorded on August 11, 2026, had a callsign that disagreed with its database registration. The aircraft database lists N2184Z as a Nanchang CJ-6, while the transmitted callsign was N2184N. Its reported positions placed the aircraft near Linden, Michigan.

The disagreement leaves the aircraft's identity uncertain: the listed registration or type may not describe the aircraft that flew. A database error, a re-registration or an avionics setting could explain the mismatch, but these records do not establish which explanation applies.
