Breakdown of co-ordination involving a Boeing 767-338ER, VH-OGI and Boeing 747, JA8190, VIPAM (IFR), on 7 December 1997

Port Moresby ATC passed coordination to Brisbane Centre on ANA923 and QFA 114 but the flight levels coordinated were incorrect. ANA 923 was coordinated at flight level 390 and QFA114 at flight level 370. At 1700, the pilot of ANA923 reported at VIPAM at flight level 370. When this was passed to Brisbane sector 11, confirmation of the flight level was requested, and this was confirmed by the pilot. Sector 11 contacted Port Moresby by telephone, and Port Moresby confirmed flight level 390.

At approximately 1710, Port Moresby called back to apologise and advise that the level coordinated should have been flight level 370, and QFA 114 should have been flight level 390.
