In December of 1980, a total of 2,656 Grumman 870 Advanced Design Buses in 27 cities, including New York, Chicago, Houston and Los Angeles, were taken out of service by their manufacturer, the Grumman-Flxible Corp., to reinforce the undercarriages on the buses. • • Because of a design flaw, numerous Grumman 870s built between 1978 and 1980 began to develop cracks in their supporting A-frames, forcing the company to remove the entire fleet from service for underframe repairs. These A-frame repairs would cost Grumman-Flxible $7 million to correct. • • The Grumman 870 A-frame problem was the focus of an evening news story broadcast on ABC World News Tonight in late-1980/early-1981. In this video clip, ABC News reporter June Massell briefly recaps the history of the Grumman-Flxible 870, its problems, and how commuters in Chicago had to cope while Chicago's fleet of 205 RTA (Regional Transportation Authority) Grumman 870s were grounded. • • In 1984, the suburban Detroit SEMTA bus system (now SMART) purchased sixteen (16) Flxible Metro coaches (#8401-8416)—a similar-appearing revised version of the Grumman 870—to service the suburbs of Detroit. Although the Flxible Metro was based on the 870, the A-frame problem had been rectified by the time the SEMTA order was placed. • • (video posted as an educational reference only) • • For more Detroit transit videos visit: • http://www.detroittransithistory.info...
