I went over parameters to see if any indications show abnormal to suggest a pole impact between :43-:44 since we know that the aircraft was over poles 1 and 2 prior to :44.

So far this is what i have..

Bleed Duct Pressure - normal/nochange
Engine RPM - normal (no indication of rollback)
AC Bus Volts - normal/no change
Left/Right Fuel pumps - High Pressure (no change)
Fuel Tank Density all tanks - normal trend (doesnt show puncture)
Engine EGT - Normal/Nochange
Engine gen - OK/ON
Engine EPR - High/No Change
Engine Fuel Flow - High/No Change (No leak)
Engine Oil Pressure - Normal
Engine N2, N3 - No change
Engine Oil Press, Temp, Quantity - Normal/No Change
Engine Vibration - Normal/No change (engine shows more vibration during take off)
Engine Out (off) - False (its running)
Fan Inlet Temp - No change
Filter Vibration - No change
Hydraulic Pumps - normal/no change
Hydraulic Pressure - Normal/No Change
Master Warning - On (Corresponds with Overspeed warning)


Thats it. As you can see, there are no indications throughout the above parameters that the airplane hit pole 1 or 2. All indications are normal

Engine indications are for both engines.

This would mean that the airplane that this FDR was in,
did not hit the light poles.

...wonder if it hit anything at all...

imo, lunk

Engine N2, N3 - No change

That suggests a three spool engine which, I think, means Rolls-Royce RB211-535E4 or Rolls-Royce RB211-535E4B as I think the P&W 2000 series are two spool.

Correct me if I am wrong but this diagram of a P&W:

Flight cut way Diagram of a P&W 2000 series

suggests a twin spool.

Could be worth keeping in mind when looking at 'official pictures' of plane debris, you know that stuff brought in special from a bone yard somewhere.

I just graphed the N1, N2, and N3 RPM columns for the NTSB-provided SSFDR data (after 09:15:00 EDT). Here is the chart:

Although it looks difficult to locate specific ones, engine cutaways are available at O892's link:
