The aircraft, affectionately known as 'Megapode', had been undergoing its heavy C-Check maintenance program under contract with Hawker Pacific based in Cairns, Queensland.
Solomon Airlines General Manager - Operations & Commercial, Gus Kraus said that after close on three months out of operation it was with a great sense of pride that the carrier welcomed the Dash 8 back into service.
"'Megapode' has been sorely missed," Mr Kraus said.
"Solomon Airlines would like to thank our valued travellers and the general public for their patience and understanding during the Dash 8's absence.
"We look forward to the aircraft once again providing a safe and comfortable return to a service that provides a vital air link for the people of the Solomon Islands.
"Naturally much more can be done with this level of commuter aircraft in the Solomon Islands and with government assistance we see much potential in opening up further ports in the Solomon Islands to a Dash 8 service."
These areas Mr Kraus said included Taro, Seghe and Lata.
The airline was also looking at the possibility of providing Dash 8 services to Manaoba and Lomlom subject to those ports being commissioned and operationally approved.
