What a cluster F@&k of an accident, immagine pulling reverse thrust the engines spool up but the reversers never deploy. Nightmare. Surprised that a 36% loss in pressure would cause a failure as I have seen tires that have lost 75% of their pressure make it to the gate w/o incident.
But then again my experience is mostly with widebodys. I would suspect a bad pressure guage, if all tires are this low, or ignorant reporting of the accident. If they were all low and the aircraft was heavy who knows.
Tires do not magically lose pressure at a controlled rate. Every tire is different. Another reason why tire pressure monitoring equipment is a nice feature.
Tires blow on big jets all the time and in my limited experience with corperate in the usa I can say with confidence for sure that there is less oversight. Most big jet operators have a program, often TP checks get doccumented every 24 hrs.
