The following episode occurred on December 20th in 2002, but was not made public until recently.

At around 8PM, while a Norwegian 737-300 was flying from Oslo to Bergen, a SAS 737 was making it's way from Bergen to Oslo. As the two aircraft were about to meet over Sigdal, the ATC decided that the Norwegian aircraft should level out at 28 000 feet. The SAS plane was cruising at 29 000 feet in the opposite direction.

However, the ATC forgot to give the instruction to the Norwegian crew, who were originally cleared to 30 000 feet.

It was not until the SAS crew reported that the oncoming traffic was still climbing towards them, that ATC realized what was about to happen. At this point he ordered the Norwegian flight to "descend immediately to 28 000 feet."

The anti-collision system in the SAS aircraft was activated, and commanded the crew to descend and turn left. The SAS crew followed these instructions.

However, the anti-collision system in the Norwegian aircraft also became active, instructing the crew to climb. The pilots however, decided to follow ATC orders to descend to 28 000 feet.

The result of this was that both aircraft began descending from 29 000 feet simultaneously. At 28 100 feet, the aircrafts passed each other separated by only 2 NM.

The commission which looked into this episode and later released the report, have mentioned the mid air collision on the border of Germany and Switzerland in July 2002.

Indeed it has eerlie connections to the DHL/Bashkirian Air mid air collision in 2002. I believe they both were descending towards the same altitude and ended up colliding. Thank god it all went uneventful this time though.

ehhh, two miles? Hardly "near collision". Stay safe Vikings!

2 NM is still too close by any internatonal operational standard. A 737 flying at crusing speed can cover that in 15 seconds, a time that could be too short to see and properly react too. Also consider the dirty air behind both aircraft that can affect the air to any aircraft within 2 miles of each of them.
Why has this only came out now? Due to investigations of other close calls or mid-air collisions?

The incident date and time are in error in the above: the correct data are Dec. 22, 2002, 1919 hours.

"Flyselskap:
Scandinavian Airlines System/Norwegian Air Shuttle
Hendelsesdato:
22.12.2002
Reg. merke:

Judging from their list of reports it is not uncommon for the Norwegian authorities to have spent several years in the investigation.

I guess my source (a norwegian newspaper) weren't too specific with the facts. Hmpf.

As for why it took them this long, I'm not sure. It seems like it can easilly take 6 to 12 months before the report is finished. This was still a bit extreme I think.

Anyway, here are the two aircrafts in question. (I think the reg should be LN-KKF, and not LN-KFF btw)

At least the text of the Commission Rapport references to LN-KFF. Perhaps someone local should let them know of the embarrassing error for the public good?

Hardly an embarrassing error...and I suspect the public doesn't give a stuff. It's only spotters who think that the registration details are more important than the content  Wink

I beg to differ. You'd not be satisfied if the bank had repossessed your car on the account of an error in the registration number by an official authority! Things like registrations just MUST be correct in the official papers and reports, there's no excuse.
