The Malaysia Airlines 777 involved in today's accident in Ukraine is tail no. 9M-MRD and serial number 28411, a 777-2H6ER that was the 84th 777 off the production line. Powered by Rolls-Royce Trent 892B-17 engines, it first flew on July 17, 1997, exactly 17 years before its accident. It was delivered to Malaysian Airlines on July 30, 1997.
This is the fifth hull loss for the 777 and the second this year. Oddly, three out of the five 777 hull losses have taken place in July. EgyptAir lost a 777-200ER in July 2011 in Cairo due to a cockpit fire and an Asiana Airlines 777-200ER crashed on landing in San Francisco in July 2013. British Airways suffered a 777-200ER loss on landing at Heathrow in January 2008 and Malaysia Airlines lost a 777-200ER somewhere in the southern Indian Ocean in March 2014.
