Jet engine maker Safran said the worst of the coronavirus crisis was over but took a cautious view on long-term airline traffic in a continuing stand-off with Airbus over proposed increases in jetliner production. The French aeronautics supplier also placed almost a third of its recently acquired Zodiac Aerospace business under review, while targeting higher revenues and margins over five years. CEO Olivier Andries said Safran remained committed to building enough engines to allow Airbus to meet a firm output target of 65 A320s a month in 2023, up some 50% from crisis-hit levels, but that it was too early to commit to more.
