On Monday night, the city's councillors will vote on whether to request a final report from its directors regarding the sale of the hangar to Regional Express in 2017.

The notice of motion - to be moved by Councillor Paul Funnell - asks for the report to outline all of the processes, negotiations, costs and documentation leading up to, and post, the sale of the hangar to Rex.

Cr Funnell said it is a necessary step as the council enters negotiations to take control of the Wagga Airport, which is owned by the Department of Defence. The department leases a section of the airport to the council for $300,000 each year.

"The council need to show good governance and why we should be entrusted with the role," Cr Funnell said.

The sale of the hanger was tainted by the council's earlier dealings with Douglas Aerospace, which nearly left the city with a $2.1 million debt after loaning money to the aircraft refurbishment company that fell into voluntary administration.

A letter outlining then-mayor Rod Kendall's concerns, which was later leaked, exposed the internal council frictions over the loan fiasco.

Then-general manage Phil Pinyon resigned three days after receiving the letter.

Amid the chaos the council was left with a "white elephant" in the form of a large aircraft hangar. But the council struck a deal with Rex in January 2016 with the purchase finalised about a year later once contractual obligations were met.

"It was one thing to get through the hurdle of the loan debacle - and it cost people their positions in this organisation. It is hard for a commercial organisation to enter an agreement with the cloud over that sale," Cr Funnell said.

After a "long negotiated" and "very costly process" to sell the hangar to Rex, Cr Funnell said the council needs to lay the "nuts and bolts" on the table for the sake of transparency and accountability.

"I am hoping the report shows that everything is above board because that is what I have been told. If there is an issue then we need to know about it," he said.

Acting deputy mayor Rod Kendall said it could be "handy to have a comprehensive report" that officially puts the matter to rest.

"I think most of the information has been made available to councillors during the process, but major infrastructure spending will always benefit from disseminating a final report," he said.

"I suspect the work will be pulling together information that's readily available in an all-encompassing report. I don't see any reason why it shouldn't be supported."

Councillors will vote on the motion at the council meeting on Monday.
