I have verified numerous approaches from the NW to PVR airport and they all look like this, basically approaching on the left side of the mountain then taking a right towards the airport: enter image description here

But then noticed 1 flight whose path is different: enter image description here Do you think that was the intended flight path or they suddenly realized they need to be further to the left ?

    $\begingroup$ That last one looks much more like a DME arc, often implemented as part of an approach; unfortunately, I don't have any Puerto Vallarta approach plates handy with which to confirm or refute this. $\endgroup$

Puerto Vallarta (MMPR) has a VOR/DME on the field (PVR), which is used in seven different approaches (that I can find) depending on where you're coming from and which runway you're landing on:

  • VOR DME 1 Rwy 04 (Teardrop)
  • VOR DME 2 Rwy 04 (DME arc from NW)
  • VOR DME 3 Rwy 04 (DME arc from SE)
  • VOR DME 1 Rwy 22 (Teardrop)
  • VOR DME 2 Rwy 22 (DME arc from NW)
  • VOR DME 3 Rwy 22 (DME arc from SE)
  • VOR Rwy 04 (Procedure Turn)

Your abnormal flight seems to exactly match the VOR DME 2 Rwy 22 coming from BLASK on airway V1/J141. So yes, that was the intended flight path.

What's interesting is that your normal flights don't match any of the procedures. I suspect that ATC is vectoring those planes to final, which saves the time, fuel and effort of flying a DME arc, teardrop or procedure turn.

If ATC can do that, though, why did that one flight do the DME arc as charted? It's possible ATC was too busy to vector at that time, or their radar was down, or there was a radio problem, or the pilot requested the full procedure to maintain proficiency, or something else. Without a recording of the ATC frequency, it's hard to say.
