The MD-87 is a smaller aircraft than other models in the series, with only one wing and shorter length. Available seating accommodates 33 people less then there are seats for on an MD-81 model of this same line (even after optional extra fuel). The maximum payload that can be carried by these planes has been reduced from 629kgs to 569 kgs – but it gives 1204km more range before refueling! It also holds 25% less volume when compared to the original design; 45% if you opt for additional fuel tanks. Seventy six were made over its production span – starting November 1st 1987 to March 8th 1991
