14CFR 91.126d as referenced in 14CFR 91.129a?


Note that FAR 91.126(d) also begins with, "Unless otherwise authorized or
required by ATC,..."


§ 91.126 Operating on or in the vicinity of an airport in Class G
airspace.

(d) Communications with control towers. Unless otherwise authorized or
required by ATC, no person may operate an aircraft to, from, through, or on
an airport having an operational control tower unless two-way radio
communications are maintained between that aircraft and the control tower.
Communications must be established prior to 4 nautical miles from the
airport, up to and including 2,500 feet AGL. However, if the aircraft radio
fails in flight, the pilot in command may operate that aircraft and land if
weather conditions are at or above basic VFR weather minimums, visual
contact with the tower is maintained, and a clearance to land is received.
If the aircraft radio fails while in flight under IFR, the pilot must comply
with § 91.185.



According to whom? I see several references to the "ATC facility having
jurisdiction over the Class D airspace area." Can there be more than one
facility with that authority?


VFR towers actually have little authority over Class D airspace, about all
they can do is require VFR aircraft to remain clear of it. Authority and
responsibility for IFR and SVFR operations rests with the overlying Center
or approach control facility, although some of that is often delegated to
the tower.
