Executive Summary:The pilot on the aircraft G-KATA, together with a passenger, was going to fly from Malmö/ Sturup to Västerås. He had submitted a VFR flight plan for the flight.

South of Malmö/ Sturup was the aircraft OY-CNP, with the flight number VKG362, on an IFR approach to runway 17. When VKG362 reported to the air traffic controller that they were descending to 5,000 feet altitude, she gave them clearance to continue the descent to 3,000 feet.

The air traffic controller in the airport tower gave the pilot onboard G-KATA the clearance “cleared to line up runway 17, enroute clearance DOMEN1, 1,500 feet or lower”. Then he received clearance to take off. The pilot took off and had the transponder selected to code 7000 and mode A, which meant that a radar echo was displayed on the air traffic controller’s radar screen, however without information about the aircraft’s altitude. Approximately six minutes later he reported to the air traffic controller that he was over DOMEN at 1,500 feet and was directed to the air traffic controller at Malmö Control. When the pilot contacted the air traffic controller at Malmö Control, he reported that he “had just left Malmö Sturup enroute to Västerås according to the flight plan”. The pilot was requested to set in code 2727 on the transponder. Then the air traffic controller cleared VKG362 to descend to 2,000 feet and cleared them for a visual approach to runway 17 via the outer marker. During the time that the air traffic controller spoke with VKG362, she saw that the aircraft G-KATA’s radar echo displayed an altitude of 2,400 feet. She then informed him that he had not received clearance to fly in controlled airspace.

The investigation showed that the pilot was unaccustomed with the aircraft type and did not notice that the aircraft continued to climb through the cleared altitude (1,500 feet). The aircraft reached 2,500 feet in controlled airspace before the climb was arrested.

The aircraft OY-CNP was equipped with TCAS, but did not receive a warning because the aircraft G-KATA had not selected the mode on his transponder that includes altitude reporting. According to the register from MUST, the minimum distance between the two aircraft was approximately 130 meters horizontally and 420 meters vertically.

The incident was caused by the inadequate monitoring of the flight by the pilot in the aircraft G-KATA. His limited experience on the aircraft type was a contributing factor.
