The sanctions also bar sales of European jets with a certain amount of U.S. parts, limiting Iran’s ability to buy from Europe.
As a result, Iran has focused on Russian-built planes – like the
Tupolev and Ilyushins, the Soviet-era workhorses for Russian civil air
fleets. After the Soviet collapse, government funding sharply declined
for manufacturers of aircraft and spare parts, and other countries
using the planes have had a harder time getting parts.
