Three manoeuvres by the Briz-M fourth stage were planned to put AMC 14 into its separation orbit (MET is mission elapsed time):
Burn 1: MET = 11m 19s to 18m 54s Parking orbit injection 51.5 deg, 173 - 173 km
Burn 2: MET = 58m 41s to 1h 33m 07s Transfer orbit 49.1 deg, 890 - 35,745 km
MET = 1h 34m 28s Separation of Briz-M auxiliary propellant tank
Burn 3: MET = 6h 36m 30s to 6h 42m 40s Target orbit 19.7 deg, 6,257 – 35,786 km
MET = 6h 55m 50s Satellite separation from Briz-M
Briz-M shut down prematurely, 2m 13s before the planned termination of the second of the above manoeuvres and 2008-011B represents the fully-fuelled Briz-M with the still-attached auxiliary propellant tank (APT) and the remaining APT propellant. This configuration is similar to that following the ARABSAT 4A launch failure (2006-006), which resulted in the disintegration of the Briz-M assembly in February 2007 – presumably as a result of the unburned propellant mixing.
