An Avro RJ100 passenger jet and a small ultralight were involved in a serious near miss incident near Nuremberg, Germany, according to a BFU report. The aircraft had a 130 m lateral and 61 m vertical separation.

On March 30, 2014, Swiss International Air Lines flight LX1190, operated by RJ100 HB-IYQ, was approaching Nuremburg Airport following a scheduled service from Zurich, Switzerland. There were 68 passengers and 4 crew members on board.

At 13:39 hours local time, the pilot of an FK9 ultralight requested permission to cross the Nuremburg CTR from Herzogenaurach to reporting point SIERRA. This was approved by the air traffic controller.
At 13:40:41 the crew of the RJ100 reported established on the ILS for a runway 10 approach at Nuremburg Airport. Three seconds later the Tower controller replied: “Grüss Gott, uh for your information, there is an ultralight aircraft at your eleven oclock position, range three miles, left to right at three thousand feet.” The crew responded that they had him on and in sight.

At 13:42:02 the Tower controller reported the position of the RJ100 to pilot of the FK9: “…traffic is a Jumbolino at your two oclock position, range two miles, out of three thousand six hundred descending, has you in sight.” The pilot of the FK9 replied: “Yes, looking out, the Jumbolino is not in sight, (call sign), we reach the extended center line now.”

The distance between the two aircraft was to this time for about 1 NM horizontally and the RJ100 was still about 300 ft above the FK9.
At 13:42:29 the crew of flight LX1190 received a TCAS Resolution Advisory (RA), instructing the crew to “Climb”. Looking outside, the pilot judged that the FK9 was already slightly above their own altitude.Therefore,  he decided against the RA. He disconnected the autopilot and descended to fly below the FK9.
The minimum horizontal distance was, according to records of the RJ100’s TCAS,  approximately 0.07 nautical miles (130 m) at an height of approximately 200 ft (61 m).
