UPS has extended the period that they plan on flying DC-8's.
This past year they did dispose of 2 DC-8-71's. One airplane had a nose gear collapse at the gate which resulted in considerable damage to the area under the cockpit. It was bandaided, ferried into storage, and then sold.
The other airplane would have required the upper and lower forward inboard wing spar caps be modified due to an AD
and an impending AD
. It would have resulted in a very expensive modification, so the plane was retired and sold.
They still have 47 DC-8's, 21 DC-8-71's and 26 DC-8-73's.
An easy way to tell the difference between the two is to look at the nose cowls. If there are strakes on the nose cowl; it is a -73, no strakes, it is a -71. -72's aso have strakes, but UPS doesn't have any of these.
The last DC-8 was produced in 1972.
