WASHINGTON, Sept 9 (Reuters) - Airbus CEO Guillaume

Faury said on Tuesday that engines remain the most challenging

part of the aerospace supply chain, as the European planemaker

seeks to grow jet deliveries.

Faury told a gathering of aerospace executives in

Washington, D.C., that he is "worried" about engines, despite

seeing improvements within the aerospace supply chain.

Airbus is aiming for a 7% increase in deliveries to 820 jets

this year, but is wrestling with delays in receiving engines and

cabin equipment.
