Perth- A Singapore Airlines (SQ) flight traveling from Brisbane (BNE) to Singapore (SIN) was forced to make an emergency landing in Perth (PER) on July 7, 2025, due to an in-flight engine problem. The Airbus A350 experienced a low-pressure alert on engine 1, which led to a controlled shutdown of the engine.
The flight crew followed established protocols by opting to divert to Perth instead of continuing to Darwin (DRW) or other nearby airports like Broome (BME) or Denpasar (DPS), with a focus on securing engineering assistance and operational logistics.
A Singapore Airlines flight, identified as SQ256 and operated by a 5.5-year-old Airbus A350-900 bearing the registration 9V-SHM, was on its way to Singapore when flight attendants received a warning about low pressure concerning engine 1.
While the exact cause of the alert remains unspecified—whether it pertained to fuel, hydraulic, or oil pressure—the engine was shut down following standard procedures.
Despite approaching Broome (BME) and other potential diversion points like Darwin (DRW) and Denpasar (DPS), the pilots chose to continue to Perth (PER), a distance of about 1,040 miles from the aircraft’s position during the incident.
This decision favored Perth due to its enhanced maintenance capabilities and logistical readiness for managing a widebody aircraft such as the A350.
The diversion to Perth guaranteed that passengers would have a smoother transfer process and that the aircraft could access prompt engineering support.
Although Denpasar (DPS) is a standard destination for the A350 with multiple airlines, the flight’s path over the less populated regions of northern Australia may have constrained emergency diversion options.
Following the landing, Singapore Airlines promptly sent a replacement Airbus A350 (registered 9V-SHP) under flight SQ9225 to Perth (PER).
The replacement aircraft took off as SQ9224 at 4:40 p.m. local time on July 8 and was expected to reach Singapore at approximately 9:40 p.m. that same day.
During their time in Perth, passengers received food and beverages. A representative from Singapore Airlines remarked, “We are providing all necessary support to affected passengers, including rebooking connections and arranging for hotel accommodations in Singapore if required.”
The airline also expressed its regrets, stating: “Singapore Airlines sincerely apologizes for any inconvenience caused.”

Similar Incident
Another incident involved a Singapore Airlines (SQ) Airbus A380 flight that had to return to Sydney (SYD) shortly after takeoff on April 7, 2024, due to a technical fault.
Flight SQ232, bound for Singapore Changi Airport (SIN), returned safely to Sydney a little over an hour after its scheduled 11:00 a.m. departure.
Singapore Airlines confirmed that its Airbus A380-841, registered 9V-SKM, faced a mid-flight technical issue, prompting the crew to head back to Sydney (SYD). The aircraft landed safely at 12:42 p.m. local time, approximately 100 minutes post-departure.
The airline reassured that the safety of passengers and crew was the foremost priority during the event. On the ground in Sydney, technicians inspected the aircraft and resolved the issue, allowing the flight to resume at 4:19 p.m., arriving in Singapore Changi Airport at 10:24 p.m. that same day.
The aircraft involved, an Airbus A380-841, features Rolls-Royce Trent 900 engines and has been in service for nearly 14 years, showcasing the age of some A380s still active.
Flight SQ232 typically serves as a long-haul connection between Sydney (SYD) and Singapore (SIN), taking about 8 hours.
