SIA Engineering's investments in capacity and geographical expansion could bear fruit as more airline customers turn to the maintenance, repair and overhaul sector amid delays in new aircraft deliveries, says OCBC Group Research's Ada Lim. Supply and manpower constraints stemming from the pandemic, alongside competition for materials and talent from the defense sector are impacting new aircraft deliveries, the analyst says. More airline operators are thus likely to require MRO services to extend the lifespans of their current fleets. In particular, SIA Engineering could secure more opportunities from customers in India, given its association with Singapore Airlines, which has a stake in Air India, she says. SIA Engineering is OCBC's top aviation-linked pick. (megan.cheah@wsj.com)
