In the last few hours, a United Airlines Airbus A321neo operating a flight from San Francisco to Chicago declared an emergency.
Information has emerged surrounding the incident at hand.
Below is what we know on this so far…
United Airlines Flight UA1568 – San Francisco to Chicago…
United Airlines flight UA1568, which declared the emergency, is a routine scheduled flight between San Francisco and Chicago O’Hare.
Furthermore, the aircraft involved in the incident was N34562.
As per data from Planespotters.net, N34562 is a 0.5 year old Airbus A321neo that was only delivered to the airline back in December 2025.
Of the A321neo variant, UA has 69 of them in their fleet, of which all of them are in active service, with an average fleet age of 1.2 years.
As well as the A321neo, the airline has the following other aircraft in their mainline fleet:
- 75 Airbus A319s.
- 67 Airbus A320s.
- 605 Boeing 737s.
- 61 Boeing 757s.
- 53 Boeing 767s.
- 96 Boeing 777s.
- 87 Boeing 787 Dreamliners.
In total, United Airlines has 1,113 aircraft in their fleet, of which 1,056 are in active service, and 57 are parked, offering an average fleet age of 15.2 years.
United Airlines flight UA1568, which declared the emergency, departed from San Francisco at 0830 local time this morning, originally bound for Chicago.
However, over the Tahoe National Forest, the aircraft made a u-turn and subsequent beeline back to SFO, whilst squawking the 7700 squawk code to indicate a problem onboard.
Around 40 minutes after the declaration, the aircraft landed safely without further incident.
Reason for the Emergency?
It is understood that the reason for the emergency onboard United Airlines flight UA1568 San Francisco-Chicago is due to a hydraulic failure, as per @FlightEmergency on X.
This is something of concern for this particular airframe, considering it was only delivered back in December 2025.
It is unclear what the nature of the hydraulic failure was, and whether there was any difficulty vacating the runway after landing.
Data from Flightradar24 indicates the aircraft is expected to operate the UA1233 service to Denver tomorrow (June 9), so it looks like a fix is already in the works to get the aircraft airworthy again soon.
As soon as we have more information on this, we will update you accordingly.
