You can deflect all you want, you WROTE ETOPS has nothing to do with Twins, but it does. Now you are attempting to change what you wrote.
Give it up, just stop, from 2008 which supersedes your 2007 claim...
Your post just confirms what I was saying, you need to actually open up the document and read what it says, not just the first result google gives you.
Now I stated clearly that ETOPS has been renamed from Extended Range Operation with Two-Engine Airplanes (ETOPS) to Extended Operations (ETOPS), it has nothing to do with twins, that is why the FAA renamed it.
The documents you quoted confirms this.
AC 120-42B - Extended Operations (ETOPS and Polar Operations)
AC 120-42A Extended Range Operation with Two-Engine Airplanes (ETOPS)
Both AC 120-42B and FAR Section 121.16 clearly states that ETOPS applies to all engine configurations, prior to this ETOPS only applied to twins, after 2007 ETOPS applies to all engine configurations, the references to it being related to twins were removed.
From AC 120-42B
“The Federal Aviation Administration (FAA) may authorize ETOPS with two-engine airplanes over a route that contains a point farther than 60 minutes flying time from an adequate airport at an approved one-engine inoperative cruise speed under standard conditions in still air (adequate airport is defined in part 121, § 121.7 and Appendix 1 of this AC). The FAA may also authorize ETOPS with passenger-carrying airplanes with more than two engines over a route that contains a point farther than 180 minutes flying time from an adequate airport at an approved one-engine inoperative cruise speed under standard conditions in still air.”
§ 121.161 Airplane limitations: Type of route.
(a) Except as provided in paragraph (e) of this section, unless approved by the Administrator in accordance with Appendix P of this part and authorized in the certificate holder's operations specifications, no certificate holder may operate a turbine-engine-powered airplane over a route that contains a point -
(1) Farther than a flying time from an Adequate Airport (at a one-engine-inoperative cruise speed under standard conditions in still air) of 60 minutes for a two-engine airplane or 180 minutes for a passenger-carrying airplane with more than two engines;
