CASABLANCA, Morocco, Dec 6 (Reuters) - The head of French jet engine maker Safran said global supply chains are still struggling to shake off a series of external shocks and warned against setting unrealistic output targets as aviation tackles a recovery in travel demand.

Speaking to reporters during a visit to Morocco to sign a pact on boosting local supply chains, CEO Olivier Andries reiterated a provisional target of 2,000 LEAP engine deliveries in 2024 and described the number as "already very ambitious".

For 2025, Andries said Safran's CFM engine venture with GE , which supplies both Airbus and Boeing, would raise LEAP output but that there was no urgency to agree precise volumes with aircraft manufacturers until around the middle of 2024. (Reporting by Tim Hepher, Editing by Louise Heavens)
