Description

On 29 December 2011, an ATR72-200 being operated by Golden Air on a scheduled passenger flight from Oulu to Helsinki for airline Blue1 was about to land on runway 22R at destination in accordance with a valid landing clearance when a Saab 340 being operated by Latvian carrier RAF-AVIA Airlines on a cargo flight from Helsinki to Mariehamn for Nordflyg and taxiing for departure from runway 22R was observed to enter the runway. A go around had already been initiated when ATC called to instruct a go around for the same reason.

Investigation

An Investigation was carried out by the Finnish SIB. ATC radar and R/T recordings and Flight Data Recorder (FDR) data from the ATR 72 were available but the Cockpit Voice Recorder (CVR) from the Saab 340 had been overwritten and it was noted that this fact had “significantly hampered the investigation of multi-crew co-operation” on the Saab flight deck.

It was established that runways 22R and 22L had both been in use as usual during the busy afternoon period, each controlled by a dedicated TWR controller, TWR-W and TWR-E respectively. Although it had been raining at the time, there was no low cloud and normal daylight visibility had prevailed at the airport so that neither in flight nor surface visibility - the latter observed as 6km - were a factor in the investigated event.
