Specifically, the investigation team concluded the failure was likely due to the accumulation of liquid and solid oxygen between the COPV liner and overwrap in a void or a buckle in the liner, leading to ignition and the subsequent failure of the COPV. The cause of the accident was attributed to the failure of one of three composite overwrapped pressure vessels (COPVs) mounted inside the second stage liquid oxygen tank. The launch vehicle and payload (AMOS 6 satellite) were destroyed. The launch vehicle blew up on the launch pad during launch vehicle propellant loading in preparation for a hot fire test scheduled two days before launch.

In 2011, SpaceX published an animation that unveiled an ambitious plan for full Falcon 9 reusability. The suspect struts were replaced with stronger struts from a different manufacturer on all subsequent flights, and enhancements were made to the hardware quality audit process. In this article, we aim to shine some light on Musk’s past statements about Falcon’s second stage reusability and explain why it is such a difficult task. The strut failure caused a breach in the high pressure helium system, which over pressurized the LOX tank within a second, leading to structural failure of the LOX tank. The overpressure event was attributed to the failure of a strut which provides structural support to the high pressure helium system located inside the LOX tank. The second stage liquid oxygen (LOX) tank experienced an overpressure event at approximately 139 seconds into flight, followed quickly by structural failure and breakup of the second stage launch vehicle, resulting in the loss of the vehicle and payload (Dragon CRS-7 spacecraft).

Improvements were made to existing engine inspection techniques, and this process vulnerability was reportedly addressed on the upgraded Merlin 1D engine. The material flaw, introduced during manufacturing, resulted in a breach in the main combustion chamber, loss of pressure, and subsequent shutdown. The engine failure was attributed to an undetected material flaw in the engine chamber jacket. The inflight main engine anomaly resulted in debris being ejected from the engine compartment, but the remaining eight engines performed nominally and the primary payload (Dragon cargo resupply spacecraft) was successfully placed into orbit. INFLIGHT MAIN ENGINE FAILURE AND SHUTDOWNĪpproximately 1 minute 19 seconds into flight, one of the nine Merlin 1C engines (engine # 1) experienced a rapid loss of pressure and was commanded to shut down by the onboard flight computer.
