Bigger Engine Change Same Commitment

China Aircraft Services Limited (CSAL) have successfully completed an AOG engine change for one of our key customers on an Airbus A330. This engine change is the first Wide Body engine change completed in the midst of the COVID Pandemic restrictions and came with additional Logistical as well as the usual technical challenges.

While narrow body engine changes are a regular occurrence in the CASL facility, Wide Body engine changes are not as regular. They typically require around 20% more resources than a similar task on a narrow body aircraft. To support this a team was formed with cooperation between both the Line and Base maintenance departments of CASL. The task was completed safely within 48 hours of commencement which was a fantastic achievement demonstrating excellent coordination between the teams. 

CASL operational departments along with Quality and safety conducted a comprehensive risk assessment. This considered aspects of health risks posed by conducting such a task at the height of the 5th wave of the pandemic in Hong Kong as well as technical risks associated with current experience of the task. Mitigations were developed for each identified risk including pre-start Rapid Antigen tests for staff and additional quality and supervision resources to ensure any potential errors were captured as a part of the process.  

The aircraft arrived was inducted into CASL hangar (one of only two wide body capable hangar facilities in Hong Kong) on 16 March. The aircraft was returned to operational service on 19 March without any issues. Customer feedback on the timing and quality of the work has been very positive.

Adrian Beirne CASL CEO stated “The dedication and excellent teamwork between the various departments is a testament to the pride that all CASL employees that in delivering an outstanding service to our customers. I would like to thank all involved for a job well done and demonstration the CASL SPIRIT!”.
