The Israel Air Force on Wednesday night grounded its fleet of Yas'ur helicopters, after a problem developed in a helicopter that was on a mission. The crew, which had just taken off from the Tel Nof air force base, noticed that there was a problem in the helicopter's rotor, and quickly returned to base. No one injured, but the helicopter was damaged in the landing.
After an examination of the problem by a grounds crew, the Air Force decided to ground the fleet until each helicopter could be examined, to ensure that they did not have a similar problem, IDF officials said. The examination should be completed sometime Thursday, they said.
The Yas'ur helicopters, made by Sikorsky Aircraft, are the largest in the IDF's fleet. Many of them are decades old, having gone through numerous repairs and upgrades, including reinforcement of their bodies and improved avionics. According to IDF budget plans, the current helicopters in the fleet are expected to continue in service until 2025.
