SINGAPORE (Reuters) – The head of the world’s second-largest aircraft leasing company said on Tuesday that Airbus may temper its hopes of raising jet production because of snags in the supply chain.

Avolon CEO Domhnal Slattery told a forum at the Singapore Airshow that the plans “may not be as ambitious as (Airbus) had articulated to the market six or nine months ago.”

The head of engine maker CFM International told the same forum that the supply chain is “under constraint right now”.

Both companies have expressed concerns about the pace of jetliner production increases. Airbus was not immediately available for comment.
