870 Frame Problems
In the mid-1980s, several Grumman 870 buses operated by the New York City Transit Authority (NYCTA) developed cracks in their underframes. This prompted NYCTA President David Gunn to remove the entire fleet from service. Soon, several other companies reported cracked 870 frames. However, the frame issues primarily affected NYCTA 870s and not the 870s owned by the franchisees of the New York City Department of Transportation. NYCTA attempted to get the remainder of its pending order for new buses transferred to GM, but was barred from doing so unless they could prove that the 870s were flawed and unsafe. The buses were eventually returned to Flxible and resold to Queen City Metro and New Jersey Transit. Grumman blamed the problems with the NYCTA 870s on NYCTA's maintenance practices, despite the fact that transit operations in Chicago, Washington, D.C., Houston, and Los Angeles had also reported problems with their 870s. Ironically, NYCTA ordered fifty Metros in 1995, but Flxible closed its doors while the order was being produced, and NYCTA obtained the remaining new buses from Orion.

Famous quotes containing the words frame and/or problems:
“A set of ideas, a point of view, a frame of reference is in space only an intersection, the state of affairs at some given moment in the consciousness of one man or many men, but in time it has evolving form, virtually organic extension. In time ideas can be thought of as sprouting, growing, maturing, bringing forth seed and dying like plants.”
—John Dos Passos (1896–1970)
““What we know, is a point to what we do not know.” Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted.”
—Ralph Waldo Emerson (1803–1882)
