Between his 1969 victory in the race and 1981, Andretti dropped out of the races due to part failures or crashes. His luck seemed to turn around in 1981. Andretti finished second in the 1981 Indianapolis 500 by eight seconds behind Bobby Unser. The following day Unser was penalized one lap for passing cars under a caution flag, and Andretti was declared the winner. Unser and his car owner Roger Penske appealed the race stewards' decision. USAC overturned the one lap penalty four months later, and penalized Unser with a $40,000 fine.
