Maybe this could give some clues for this tragic accident. Just add all these factors:
Airline pressure
A pilot in training
Marginal weather
Non-precision approach
High landing weight
A reported brake action poor runway
One deactivated reverser
AND
Airbus A319 A320 A321
Temporary Revision N 924-4 Jun06
Subject: DEGRADED BRAKING EFFICIENCE DURING LANDING
SUMMARY OF PREVIOUS ISSUES Issues 1 to 3
A few cases of degraded braking efficiency occurred during landing, while the aircraft was at low speed (approx. 60 Kt), and in AUTOBRAKE mode.
.
REASON FOR ISSUE 4
Pending decertification of above-mentioned tires, this TR is reissued to specify that:
- Some of reported cases reveled that, when a landing is initiated whit the AUTOBRAKE, degraded braking efficiency may continue even after the flight crew changes to manual braking by using the pedals.
- In the event of a lack in braking efficiency, the LOSS OF BRAKING procedure (FCOM 3.02.32) applies.
