The landowners are demanding the National Government to pay K15 million in outstanding land compensation or they will shut the airport permanently.
Spokesperson Barthimias Kaipa said for so long, their land compensation requests have been falling on deaf ears since 2006, when they lodged their claim.
He said their claims had been processed by government agencies and were paid to illegitimate landowners.
They have presented their petition to Girua Airport manager Eki Wally on behalf of Minister for Civil Aviation Alfred Manasseh last Friday.
This had resulted in the temporary shutdown of the airport, disrupting Air Niugini and PNG Air flights.
The landowners also condemned the remarks made by the Ijivitari Member Richard Masere during the recent airport opening.
Masere stated during his speech that the airport landowners should not be entertained by NAC and the national government.
The landowners have stated in response, in their petition to the Minister for Civil Aviation, that Masere is not a landowner and neither have they mandated him to speak on their behalf.
They further stated that Masere will not be allowed to be involved in any way in this matter.
