  This is a question of how you define "special relativity":

  - When accelerated motion is being described, do you deem
    this to be SR?

  - When the observer himself is being accelerated, is this 
    still SR?

  In his early 1905 paper, Einstein focused on inertial frames.

  But in 1973, the book "Gravitation" (Misner et al.) said,

|Accelerated motion and accelerated observers can be analyzed
|using special relativity.
(page 163).

  So, it seems, today, both kinds of acceleration are deemed to
  still be part of SR.

  Only when spacetime is /curved/ it's deemed to be GR. (See 
  chapters 6 and 7 of that book.)

  (The metric for an accelerated observer in SR [using Rindler
  coordinates] looks like a homogeneous gravitational field,
  but even this is still SR!)
