Eurowings flight #EW1100 from Dusseldorf to New York on 27 July 2018, operated by Brussels Airlines, stopped climbing at 20,000 feet just after crossing the Dutch border. The Airbus A340-300 registered OO-SCX descended to 14,000 feet and dumped fuel over the North Sea. The aircraft then returned to Dusseldorf where it landed about two hours after its take-off. The reason for the diversion is technical.

According to The Aviation Herald, the same aircraft returned to Düsseldorf the next day for the same reason: a bleed air leak problem with one of the right-hand engines (CFM56).

As I understand and found out: The aircraft encountered engine problems for the first time on JULY 26, the aircraft was overhead the English Channel at FL320, dumped fuel and returned to DUS.
A replacement aircraft (OO-SCW) departed DUS at 1523L and landed at JFK at 1711L.
The next day, JULY 27, the aircraft developed engine problems again, overhead the Dutch border at FL200, dumped fuel at FL140 and returned to DUS.
The flight was cancelled.
A local testflight departed DUS on JULY 29 0820L, reached FL390 and landed back at DUS 0909L.
The aircraft resumed service (EWG1100 DUS-JFK) few hours later.
