NEW YORK — Boeing's outgoing Chief Executive Officer (CEO) Dave Calhoun will testify before a US Senate panel later this month to answer questions about safety and production issues at the aircraft manufacturer, the company said on Wednesday.

The June 18 appearance in front of the Senate Permanent Subcommittee on Investigations follows an April hearing, in which four whistleblowers alleged there were safety problems in the production of three of the four commercial planes currently produced by Boeing — the 737 MAX, the 787 Dreamliner and the 777.
