First off, in my last post I overlooked the decimal point, the child found was reported to be 8.0 km (4.3 NM
) from the primary crash site, and not 80 km.
Regarding the Egyptian crash investigation news conference this morning, IMO the following critical questions arise:
- Why didn’t the exact Z time of the CVR “noise” incident get disclosed relative to the exact Flight departure time and exact time of the cessation of the DFDR data which were noted in the news conference? The time synchronization of unusual CVR events and DFDR cessation and monitored data anomalies is critical. Did DFDR data continue after the CVR “noise” incident?
- Why not say that cockpit conversations were normal and typical up to the point of the noted “noise” incident and note the sudden noise incident as unusual relative to normal/typical cockpit conversations. There really needed to be some kind of descriptor (e.g. “serious”, “unusual”, “non-normal”, “high amplitude/db”) instead of just noting a “noise” incident.
- Was there a pressure hammer/spike recorded on the DFDR monitoring of the cabin differential pressure (psid- inside of cabin to outside of the aircraft) and cabin altitude (ft.)? What was the Z time of this spike relative to the Z time of the CVR noted “noise” incident?
- If after a week of not finding some crash debris (which is the most critical debris relative to parts of the aft section of the aircraft and THS and any aircraft debris at/near the child found 8 KM
away from the primary crash site, there was amazingly no mention of the urgent measures employed to find this critical debris. That is worrisome.
- Why was there no mention in the news conference that simultaneous investigations are occurring relative to airport terminal surveillance video logs (including those within the cargo handling area and aircraft area proper), interviews of all airport employees and contracted aircraft service employees, security swipe card logs timed with surveillance videos, etc.?
