Actually this was a reader comment claiming the ICAO code was moved. However, this information is wrong.
Both FLSK (FL Simon Kapwepwe) and FLND refer to the very same airport, identify the same coordinates and same procedures.
The airport was named Ndola International until 2011 and had ICAO Code FLND.
In 2011 it was renamed to Simon Mwansa Kapwepwe and changed the ICAO Code to FLSK.
According to Zambia Airport Services FLSK is used until today. However, after referring to FLSK since 2011 the CAA used FLND again in a NOTAM summary released in Jan 2020 (15 months ago). Hence that confusion about the ICAO identifier.
But again, as both identifiers show the same coordinates and procedures, no confusion of the airport.
The new Copperbelt Airport has not yet been documented at all and has no ICAO code.
