Incident Summary
A One Air Boeing 747-400 Freighter (G-ONEE) performing positioning flight HC-932P from Cardiff (UK) to Zaragoza (Spain) experienced an engine failure while climbing out of Cardiff’s runway 12. The crew stopped the climb at FL240 and opted to divert to East Midlands Airport, where the aircraft landed safely on runway 09 approximately 50 minutes after departure.
The aircraft remained on the ground in East Midlands for at least 29 hours after landing, pending further inspection and maintenance.
Sequence of Events
1. Takeoff & Initial Climb
• The aircraft departed from Cardiff’s runway 12 on a positioning flight to Zaragoza, Spain.
• During climb through FL240, the crew detected an issue with one of the four Pratt & Whitney PW4056 engines.
2. Engine Failure & Diversion Decision
• The affected engine failed, prompting the crew to declare an emergency and halt the climb at FL240.
• A decision was made to divert to East Midlands Airport, which offers superior maintenance facilities for large freighters.
3. Approach & Safe Landing
• The aircraft landed safely on East Midlands’ runway 09 without further incident.
• Emergency services were on standby but no further intervention was required.
Aircraft Status & Investigation
• The Boeing 747-400 remains grounded at East Midlands Airport, undergoing inspections and maintenance checks.
• The cause of the PW4056 engine failure is under investigation, with likely factors including:
• Mechanical failure
• Compressor stall or surge
• Bird ingestion or foreign object damage (FOD)
• Fuel system irregularities
Analysis & Recommendations
• Engine shutdowns in-flight are rare but Boeing 747-400 aircraft are designed to operate safely on three engines.
• Operators should conduct thorough engine inspections following any uncommanded shutdown to identify contributing factors.
• Future flights should ensure post-maintenance engine performance validation before returning the aircraft to active service.
