A Bell 212 helicopter operated by the Brunei air force crashed on 20 July, killing 12 of the 14 aboard.
The bodies of all 12 fatalities have been recovered, while the two survivors are being treated, Brunei's ministry of defence said in a statement.
The crash occurred in Brunei's Ulu Belait region as the aircraft returned to the capital Bandar Seri Begawan from a training operation.
In early March, another Bell 212 operated by Brunei suffered a landing mishap. Of the three occupants, the pilot and co-pilot were unhurt, but a passenger suffered minor injuries.
In November last year, Brunei announced that it will obtain 12 Sikorsky S-70 Black Hawks to replace its Bell 212s and MBB BO105s.
