What was the name of the 1989 U.S. stock-market drop linked to leveraged buyout fears?

The 1989 U.S. stock-market drop linked to leveraged-buyout fears was called the Friday the 13th mini-crash.

On Friday, October 13, 1989, the Dow Jones Industrial Average fell 190.58 points, or about 6.9%. The immediate trigger was the collapse of a proposed leveraged buyout of United Airlines. Investors worried that the failure signaled broader problems in the market for highly leveraged corporate takeovers.

The decline was severe but short-lived compared with the 1987 crash. It occurred after a period of strong gains and heightened interest in leveraged buyouts, in which borrowed money finances the purchase of a company. This event is sometimes confused with Black Monday, which occurred in October 1987 and involved a much larger one-day percentage fall. It is also distinct from the 2010 Flash Crash, when U.S. markets plunged and recovered within minutes because of rapid automated trading.
