New York City Transit ordered 851 Grumman Flxible 870 buses in 1980. However, these buses were removed from service following several incidents in which cracks in the metal "A frames" of the buses were discovered. After repairs were made, the buses were returned to service until 1984, at which point they were permanently withdrawn from service in New York City following a fire on board a bus. Ultimately, the buses were sold to other transit agencies (New Jersey Transit, Queen City Metro in Cincinnati, Pioneer Valley Transportation Authority in Massachusetts, and an agency in Puerto Rico). NYCT did not order from Flxible again until the mid-1990s, at which time it ordered Flxible Metro-Es. However, Flxible would enter bankruptcy and shut down before any of the buses were built. A single Grumman Flxible 870, number 236, was preserved; it had been one of 16 buses retained while lawsuits between NYCT and Grumman were litigated.
