Bombardier awaits results of investigation into cause of two deadly crashes

Montreal-based Bombardier is awaiting the causes of two deadly crashes over the past couple of days involving its commercial and business planes.

At least 50 people were killed today when a US Bangla Airlines Q-400 passenger plane carrying 71 people from Bangladesh crashed and burst into flames as it landed in Nepal's capital.

The incident came a day after all 11 people on board a private Turkish Challenger 604 business jet crashed and burst into flames on an Iranian mountainside.

That plane was carrying a wealthy businessman's daughter and her friends home from a Dubai bachelorette party.

Bombardier spokesmen say they were saddened by the accidents but insisted the planes are safe and reliable.

Mark Masluch of the business jet division called the back-to-back crashes an ``unfortunate coincidence.''

The causes of both crashes aren't immediately available.

Bombardier is waiting for invitations from Nepalese and Iranian officials before sending investigation teams to the crash sites.

The Q-400 has sustained several landing gear incidents over the years but this is just the second crash of the aircraft resulting in death.
