SEATTLE: Hopes of an imminent breakthrough in deliveries of Boeing Co’s 787 jetliner were fading after a top supplier reported a lull in activity and two industry sources said the jetmaker continued to wade through lingering factory problems.

       Boeing shares fell 1.4% on the eve of quarterly earnings due yesterday, reaching their lowest level since Sept 21 as uncertainty continues to plague its main commercial programmes.

       More than 100 long-haul 787s are parked, locking up an estimated US$9bil (RM37.3bil) in cash, after a series of manufacturing issues over the past two years compounded weak demand.

       “There is a substantial risk that Boeing will recognise a charge related to the programme at third-quarter results,” Bernstein analyst Doug Harned wrote last week.

       The 787 problems have stifled a crucial source of cash as Boeing’s main cash cow, the 737 MAX, recovers gradually from a two-year safety crisis triggered by fatal crashes.

       “We are progressing through our comprehensive inspections and reviews, and will continue to take the time necessary to meet the highest standards, while coordinating closely with our suppliers and customers,” a Boeing spokesperson said when asked about the 787 issues.

       While the MAX received Western approvals late last year, Boeing faces renewed uncertainty over the timing of its re-entry to service in China, which drives a quarter of its sales.

       China had been expected to approve the MAX in November but chances are growing this will slip to next year, sources said. —Reuters
