In video, Clifford claims 110-page lawsuit is publicly available. No luck in locating. Clifford makes following points regarding liability:

American Airlines
- Knowingly operated and expanded operations into an airport (DCA) with \x93massive congestion\x94
- Operated in airspace subject to numerous near-miss reports

AA/PSA Pilots
- Failed to respond to traffic alert 19 sec before collision
- Accepted visual approach to runway 33

I think the point here is that, had the 5342 pilots followed PSA procedures (i.e., not accepting an approach that wasn\x92t previously briefed), they would have refused the circle 33 offer by ATC, thereby avoiding the accident.

Reviewing the 5342 CVR, runway 33 was not included in the CA/PF\x92s approach briefing about 35 minutes prior to the expected landing time. The CA/PF did do an abbreviated briefing for 33 after the circle 33 option was accepted.

Recall that the accident Blackhawk flight crew likely had a Stratus 2S onboard that could have provided ADS-B traffic info via the flight crew\x92s Army-issued EFBs loaded with ForeFlight. There is no evidence from the Blackhawk CVR (or the aircraft\x92s flight path) that this feature was used.

As I recall from the interviews, there was no Army aviation policy about how this technology was to be used during DC area flights. Some crews used it, but most did not.

The interview transcripts indicated that the 12th AB Blackhawk pilots used barometric altitude as the reference for flying the DC routes.

Agree. Disappointed with this PC. It would be like a DCA arrival landing on 1 has an intersection collision with an aircraft landing on 33 and the cause is the existence of one or the other intersecting runways. There\x92s a nearly infinite number of points in the NAS where two aircraft can occupy the same point if not procedurally separated.
