Docked with Salyut 7. Transported a crew comprising ship's commander V A Dzhanibekov, flight engineer S E Savitskaya and cosmonaut-research I P Volk to the Salyut-7 orbital station to conduct scientific and technical studies and experiments. Recovered July 29, 1984 12:55 GMT.
Planned but cancelled manned flight to Salyut 7. Breakdown of Salyut 7 led to cancellation of this flight and its replacement by the Soyuz T-13 repair mission. Savinykh served on the repair mission while Vasyutin and Volkov flew on Soyuz T-14.
Docked with Salyut 7. Delivered to the Salyut-7 orbital station a crew consisting of flight commander V A Dzhanibekov and flight engineer V P Savinykh to carry out emergency repairs to inert Salyut 7 station and to conduct scientific and technical research and experiments.

Installed solar array.
Manned three crew. Transported to the Mir orbital space station a Soviet-Syrian crew comprising cosmonauts A S Viktorenko, A P Aleksandrov and M A Faris to conduct joint research and experiments with cosmonauts Y Romanenko and A Laveykin. Maneuvered from initial 231 X 217 km orbit to Mir's 311 X 359 km orbit. Docked with rear Mir port at 3:30 GMT 24 July. Undocked with rear port 30 July and docked to forward port. Undocked 05:55 GMT 29 December. Returned Aleksandrov, Yuri Romanenko (Soyuz TM-2), Anatoly Levchenko (Soyuz TM-4) to Earth. Recovered December 29, 1987 09:16 GMT. Landed near Arkalyk.
Transported to the Mir orbital station a Soviet/Bulgarian crew comprising cosmonauts A Y Solovyev, V P Savinykh and A P Aleksandrov (Bulgaria) to conduct joint research and experiments with cosmonauts V G Titov and M K Manarov. Interim orbit 343 x 282 km. Maneuvered to Mir's 355 x 349 km orbit. Docked 15:57 GMT 9 June to Mir's aft port. Moved to forward port 18 June. Undocked 22:55 GMT 5 September. Jettisoned Orbital Module 23:35 GMT 5 September. Planned landing 02:15 September 6 1988 failed due to confusion of infrared horizon sensors. Repeat retrofire attempt one orbit later resulted in a partial burn only. The crew had to spend a tense 24 hours in the cramped Descent Module (the Orbital Module having already been jettisoned before the retrofire burn) before making last chance deorbit. Finally Lyakhov and Afghani cosmonaut Mohmand (Soyuz TM-6) returned safely to Earth and landed September 7, 1988 00:50 GMT, 160 km SE Dzhezkazgan.
