Thanks a lot Anik !

I just founded that the event is also scheduled on NASA TV

(unfortunately, they only use Central East Time and not UTC, it's not really easy to convert for other countries)

The landing times indicated in the Tsup page dedicated to the Soyouz-TMA14 are contradictory: a 1h lag between the time indicated in the table and the diagram...

Where is the right landing time?

They use Moscow Standard Time (UTC+3) in the diagram and Moscow Summer Time (UTC+4) in the table.

Certain sources at TSUP-M indicate that "not everything is good with an engine at TMA-14". What's this?

Just sensor issue, no concern for undocking/descent: http://forum.nasaspaceflight.com/index.php?topic=15737.msg488471#msg488471

What the Soyuz TMA-14 crew will experience during their reentry/descent tonight:

* For the reentry, Padalka, Barratt, and Laliberté will wear the Russian Kentavr anti-G suit. [The Kentavr garment is a protective anti-g suit ensemble to facilitate the return of a long-duration crewmember into the Earth gravity. Consisting of shorts, gaiters, underpants, jersey and socks, it acts as countermeasure for circulatory disturbance, prevents crewmember from overloading during descent and increases orthostatic tolerance during post-flight adaptation. Russian crewmembers are also advised to ingest fluid-electrolyte additives, viz., three sodium chloride tablets during breakfast and after the midday meal, each time with 300 ml of fluid, and two pills during the meal aboard Soyuz before deorbit.]
* Before descent:
Special attention will be paid to the need for careful donning of the medical belt with sensors and securing tight contact between sensors and body.
During preparation for descent, before atmosphere reentry, crewmembers settle down comfortably in the Kazbek couches, fasten the belts, securing tight contact between body and the seat liner in the couch.
* During de-orbit:
Dust particles starting to sink in the Descent Module (SA) cabin is the first indication of atmosphere reentry and beginning of G-load effect. From that time on, special attention is required as the loads increase rapidly.
Under G-load effect during atmosphere reentry the crew expects the following experience:
Sensation of G-load pressure on the body, burden in the body, labored breathing and speech. These are normal sensations, and the advice is to "take them coolly". In case of the feeling of a lump in the throat, this is no cause to "be nervous". This is frequent and should not be fought. Best is to "try not to swallow and talk at this moment". Crew should check vision and, if any disturbances occur, create additional tension of abdominal pressure and leg muscles (strain abdomen by pulling in), in addition to the Kentavr anti-G suit.
During deployment of pilot parachute (0.62 & 4.5 square meters), drogue chute (16 sq.m.) and main (518 sq.m.) chutes the impact accelerations will be perceived as a "strong snatch". No reason to become concerned about this but one should be prepared that during the parachutes deployment and change ("rehook") of prime parachute to symmetrical suspension, swinging and spinning motion of the SA occurs, which involves vestibular (middle ear) irritations.
* It is important to tighten restrain system to fasten pelvis and pectoral arch.
Vestibular irritation can occur in the form of different referred sensations such as vertigo, hyperhidrosis, postural illusions, general discomfort and nausea. To prevent vestibular irritation the crew should "limit head movement and eyes movement", as well as fix their sight on motionless objects.
* Just before the landing (softened by six small rocket engines behind the heat shield):
Crew will be prepared for the vehicle impact with the ground, with their bodies fixed along the surface of the seat liner in advance. "Special attention should be paid to arm fixation to avoid the elbow and hand squat" (instruction). Landing speed: ~9.9 m/sec.
* After landing:
Crew should not get up quickly from their seats to leave the SA. They were advised to stay in the couch for several minutes and only then stand up. In doing that, they should limit head and eyes movement and avoid excessive motions, proceeding slowly. They and their body should not take up earth gravity in the upright position too quickly.
