A routine short-haul hop between Spain and the United Kingdom ended back where it began on March 3rd 2026, after an Iberia Airbus A350-900 turned around mid-flight due to reported electrical issues.
The Iberia Airbus A350-900, registered EC-NJM, was operating flight IB-721 from Madrid to Heathrow Airport. The aircraft had climbed to Flight Level 400 and was cruising over the Gulf of Biscay, approximately 240 nautical miles north of Madrid, when the crew elected to discontinue the flight.
According to a passenger on board, the captain announced that the aircraft was experiencing electrical problems and would need to return to Madrid as a precaution. The jet descended to Flight Level 390 for the return leg and landed safely on runway 32L at Adolfo Suárez Madrid–Barajas Airport about 90 minutes after departure.
After landing, the same passenger reported observing that the flaps remained extended during taxi, the aircraft appeared to be operating on the right-hand Rolls-Royce Trent XWB engine only, and the landing gear doors were still open—details that may indicate the crew was managing system abnormalities while returning to the gate.
The scheduled rotation onward to London was cancelled. Approximately 23 hours after landing, the aircraft remained on the ground in Madrid for technical inspections and troubleshooting.
Modern widebody aircraft are equipped with multiple layers of redundancy in their electrical systems, but any irregular indications—particularly on a twin-engine long-range jet—are treated with caution. In this case, the crew’s decision to turn back ensured the issue was addressed on the ground rather than over open water en route to the UK.
