Aluminium Shuffler, SOP actually dictates to leave brakes RELEASED UNTIL COOLING TIME IS SATISFIED (Cooling Time can only be calculated from pink laminated card which is a copy of pages from PI section in FCOM).
It is amazing how many pilots do not realise how to use brake cooling charts!

Few years ago, a B737-300 (EI-COK) was damaged in Naples on the RH side elevator : a towed ladder hid from behind, causing a damage
very similar to that in the picture.
An AOG team from Boeing arrived with complete stab+elev; after 5 days and 700k something, a/c flew again.
Hopefully in this case the only Italian burocracy involved was related to issuing of the airport security pass for the team, but it was anyway faster than obtaining similar pass in JFK

From company source: the chocks were not in place, nothing said about parking brake, the a/c was unattended and rolled across the ramp.
Maybe the pressure on the parking brake was not enough to stop the a/c from moving.

It doesn't matter much if the park brake is set or not if there's no pressure in the accumulator. I have seen some aircraft (no experience of the 737) where the accumulator pressure would disappear inside an hour.

Same In 737, HYD pressure stores in accumulator for parking brake. It does dissipate over time and slowly releases the brakes. So aircraft should always be chocked otherwise it will go building hunting as per this one in CIA.

More than likely just a replacement of the THS and elevator, assuming a detailed visual and NDT inspection confirms no damage to the stab mounts etc. The impact couldn't have been that hard or the building would have ripped the end of the stab off!
Very unlikely that this will be a write off.

No,i was refering to post #13 from DC9-32.
Now i am refering to your statement:
I quoted 8 hours which is given by boeing for a fully charge accumulator.
As a captain,the accumulator must be checked before shutting down the engines,it is airmanship and in my current Airline,SOP.

If that's correct, Skyjob, and it should be, someone needs to let all the line trainers know. I kept on getting in trouble for it during line training when I first joined the company, being criticised for importing others' SOPs...
The point I am trying to make is that we are told in an earlier post that there was a strike at Ciampino that day. It could therefore have easily been on the ground for 36 hours or so before it went walkabout and that is well outside the guaranteed 8 hours quoted by Boeing. All you need then is some kind soul to borrow the chocks for some other purpose and the rest is history.

Me too, when chocks were installed on a ramp made slushy by de-icing fluid and with a bit of a slope. The key is to not just gently put the chock in place on top of the slush but to remove as much slush as possible and jam the chock against the gear and perhaps give it a good downward but angled kick between the wheel and the pavement.

The tables in the back of the QRH used for calculating cooling schedules for the brakes after landing/RTO.
Temperature gauges would be nice and a good safety tool, but hey, they cost a little more (next to nothing on the cost of the aircraft), so let's do without that... I wish Boeing would make them mandatory like Airbus did. Maybe they were decided against by so many companies because they might delay the next departure?

They're probably more accurate than the QRH tables, which are going to incorrectly assume even braking across all four wheels and steady retardation. Frankly, how often are they even looked at?
