An Aer Lingus Airbus A330-300, registration EI-EIK performing flight EG-44 from New York JFK,NY (USA) to Manchester,EN (UK) with 315 people on board, was enroute at FL380 about 590nm eastnortheast of Goose Bay,NL (Canada) when the crew decided to return to New York due to electrical problems rendering the aircraft unable to ETOPS operation. The aircraft landed safely back on JFK's runway 31R about 6.5 hours after departure.
On Mar 6th 2026 the Canadian TSB reported that during cruise the first officer noticed the temperature for IDG (integrated Drive Generator) #1 was higher than for the IDG #2, a short time later the crew received an advisory for IDG1. Following the checklists the crew shed load, shut the generator #1 down to affect the IDG1 cooling. When the generator was reconnected, the advisory reappeared quickly. Due to the APU being inoperative the crew decided the aircraft was unsuitable for ETOPS and turned back towards New York. On approach to New York the crew also received indications for Left engine (CF6) bleed air fault and abnormal bleed configuration. The crew worked the related checklists and continued for a safe landing. The TSB wrote: "The deferred APU was rectified (low pressure fuel shut-off valve actuator) and the number 1 IDG was subsequently replaced, as was the number 1 engine bleed pressure regulating valve."
