The maker of the helicopter that crashed and killed former NBA superstar Kobe Bryant on Sunday pledged to investigate the incident.
Defense contractor and aerospace giant Lockheed Martin said it would probe the crash of its Sikorsky S-76B helicopter in Calabasas, California, near Malibu, which killed nine people.
The S-76 series helicopter debuted in the 1970s. Sikorsky has made several major upgrades to it since then, including the most recent S76-D model. The company has sold than 875 worldwide, including 103 units of the S-76B, Sikorsky spokesperson Callie Ferrari said in an email.
The helicopter was "originally built for the rigorous demands of the offshore oil & gas" industries," but "its capabilities fit naturally into other market segments," including executive transportation and emergency services, Lockheed Martin says on its website.
Lockheed Martin acquired Stratford, Connecticut-based Sikorsky Aircraft in 2015. At the time, Sikorsky had nearly 15,000 employees in 11 countries. All five branches of the U.S. military use its helicopters in some capacity.
The National Transportation Safety Board and the Federal Aviation Administration are also launching investigations of the crash, FAA spokesman Allen Kenitzer said in an email to USA TODAY.
