Five years?  Am I getting old...I thought I heard 2 weeks earlier in the post (or was that just a WAG)?

FAILURE REVIEW OVERSIGHT BOARD (FROB) CONCLUDES INVESTIGATION ON RUSSIAN FEDERAL TELKOM-3/EXPRESS MD-2 FAILURE;

PROTON RETURN TO FLIGHT SCHEDULE ESTABLISHED

 

Wednesday, September 12, 2012-The Failure Review Oversight Board (FROB) concluded the review of the Russian State Commission report on September 11 concerning the root cause of the Russian Federal Telkom-3/Express MD-2 mission failure which occurred on August 7.  The FROB agreed with the Russian State Commission that the root cause of the failure was due to a component of the pressurization system that was not manufactured to specifications.  This caused a shutdown of the Breeze M Main engine by the Breeze M flight control system 7 seconds into the planned 18 minute and 5 second 3rd burn.

 

The corrective action plan for all Breeze M upper stages that was established by the Russian State Commission and Khrunichev State Research and Space Production Center (KhSC) was also approved by the FROB. This includes stringent quality oversight of all rework procedures, testing, support equipment, and personnel, both at the KhSC production facilities and in Baikonur. In addition, ILS and KhSC will develop specific initiatives to enhance the unified Quality Management System (QMS) that is installed and operating at all KhSC production facilities.

 

“This is an opportunity to learn, enhance and improve the overall reliability and processes of our systems,” said acting ILS Vice President and Chief Technical Officer, John Palmé. “I would like to thank the nine representatives of ILS customers, two insurance underwriting representatives and independent outside subject experts who participated in the ILS FROB process for their professionalism and diligence. We appreciate the patience and support of our customers as we plan for the return to flight of the Proton vehicle.”

 

The return to flight corrective actions and will be completed prior to the ILS Proton return to flight mission with the IS-23 satellite for Intelsat S.A. of Luxembourg in mid-October. A Russian Federal mission will follow.

"The Breeze-M upper stage failed to deliver sufficient thrust on the third of its planned ignitions because of a small metallic orifice inside a fuel line that was not manufactured according to specifications, McKenna said.

The component was built by Polyot of Omsk, Russia, in a manufacturing plant owned by Khrunichev Space Center of Moscow, which is Proton’s prime contractor and for the last several years has assembled most Proton subcontractors under its management.

McKenna said the defective pressurization-line component was built by Khrunichev until 2011, when it was moved to Polyot in 2011 as part of a general reorganization of Proton assembly.

The Polyot-built component has flown on several flights without failing, a fact that McKenna said helps explain why the defect, which he said was due to a misunderstanding at Polyot of how the part should be built, escaped Polyot and Krunichev review tests.

Given that the defect only occurred at certain pressure thresholds, McKenna said, it was not picked up as the component was tested with Khrunichev oversight.

The component will be removed from two Breeze-M upper stages awaiting integration at the Russian-run Baikonur Cosmodrome spaceport in Kazakhstan. The components will also be replaced at those Breeze-M stages at Khrunichev. It is not yet entirely clear, he said, how quickly replacement components can be qualified and installed into new Breeze-Ms, which is why the company will refrain from announcing a manifest for a few weeks"

Two Briz-M ? The one for Luch-5B arrived there on 20th July, but what is the other one ? The one for Intelsat-23 ?

Yes, for Intelsat-23 and Luch-5B/Yamal-300K. But if I have understood correctly these upper stages will be returned to Moscow. Other upper stages will be used for these launches.

Intelsat-23 was to have used the Briz-M delivered for Sirius-FM6?

Bob Christy has reported that there are rumors that the dormant Briz-M has exploded in orbit on October 16.  :P Note that Spacetrack's last TLE for the stage (2012-044C/38746) was issued on that day, although no debris has yet been identified.

USSTRATCOM confirms that Briz-M broke up in orbit on October 16 and the debris field created is under investigation for potential impact risks.

Not included here in the NASA statistics is the break-up of a Briz-K upper stage on 26 December 1994. Remarkably, this break-up occurred just hours after the Rokot delivered the Radio Rosto satellite to orbit. Briz-K was the original version of the upper stage, apparently developed as a propulsion system for the Naryad ASAT system.

The ODQN article addressed Briz-M events exclusively.  The 14th edition of the NASA History of On-orbit Satellite Fragmentations (available here:  http://orbitaldebris.jsc.nasa.gov/library/references.html) includes the Briz-K event as the RS-15 R/B fragmentation.
