I have a question about the FAA issued 250kts below 10000ft restriction. In the FAR 91 it says only the administrator can change this, then, can I accept a clearence to maintain 280kts at 5000ft given by ATC?¿

No you cannot, not under any circumstances. If you could it would state "unless otherwise authorized by ATC."
Th only exceptions are listed in the regulation, such as heavy takeoff requiring greater than 250 once cleaned up. Some operators take that interpretation; some don't.

Isn't that only valid as long as one is over land or within the 12 miles zone along the coasts of the US? I thought over international waters ATC can issue speeds greater than 250kts below 10.000ft.

The regulations suggest that is correct
Quote:
§ 91.101 Applicability. This subpart prescribes flight rules governing the operation of aircraft within the United States and within 12 nautical miles from the coast of the United States.
in same part of regs
Quote:
§ 91.117 Aircraft speed.
(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).

And, the regulation basically allows the pilot to go fast beyond 12 miles unless ATC slows him down.
But, this is at the edges of the regulation, so to speak.
Which was a common practice coming off the 'reef' runway at HNL and headed out low to run navaid checks on USN ships. Especially if there was a 'VFR' ceiling and you had to stay below it to find the boats visually.
We used the FI aircraft for training, but FI requested our instructor support in the right seat from time to time, so the non-typed guys could get a chance fly a 72. Approached a P-3 head-on, eyeball to eyeball at about 500' above the water one afternoon.....
Old duffer (King Air guy) in the left seat said to me, "Here please take it and miss him!"
At one time at least, departures out of KIAH were procedurally authorized higher speeds below 10,000'. We'd depart on 15R and accelerate to 300K for the climb-out.
"...no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots..."
...but not to worry, it would be OK with the FAA to do 280 knots at 5000 feet AGL at places like mile-high Denver; 8,300' Bogota; 9,200' Quito; 13,300' La Paz...

Yes, I remember that. Quite a bit of fun taking off south, in the 727, and by the time we would turn around and pass the north side of IAH we'd be doing close to 300 kts. After the controllers got use to us, we'd be given around a 180 turn to the north, which allowed me/us to complete the turn within the airport boundary, on southern takeoffs.
As this was usually the last stop of the day, this meant we could get to happy hour quicker.
But last I heard, that special procedure was canceled years ago.
Yeah, it was fun coming out of IAH. ALPA raised a fuss saying there was no data on bird strike damage at speeds above 250. As if bird don't fly above 10,000 feet. I figured they were worried about less block time cutting into their pay.
