 module was fitted with a special extension with foot restraints, as well as with containers for 25 special tools. Kizim and Solovyov spent 4 hr, 15 min outside Salyut 7 on April 23. They attached the ladder and prepared the repair site. On April 26 the cosmonauts cut through thermal insulation and the station’s hull to reach the damaged plumbing. They installed a valve in the reserve propellant line before going back inside Salyut 7. The second EVA lasted about 5 hr. On April 29 they again returned to the repair site. They installed a new propellant line to bypass the damaged section in 2 hr, 45 min. During a fourth EVA, on May 4, Kizim and Solovyov installed a second bypass line and covered the opening in Salyut 7’s side with thermal insulation. However, they were unable to complete repairs because they lacked tools to close the bypassed propellant line. The fourth EVA lasted 2 hr, 45 min.
