No details in the system (that I can see). Just a simple airborne return for maintenance. Because it was just a standard return I'd suspect that it was something that couldn't be MEL'd due to the ETOPS crossing.

In part answer to my own question:
Flightstats show 1st departure at 4.15 then "re directed" at 5.15 followed by "diverted" with arrival back in YVR at 5.56 and 2nd departure to OGG at 8.15.

It appears that the return to YVR was due to an engine snag of some sort.

Are these old 767s just unreliable? There seem to be a number of instances of mechanicals on these Hawaii flights. Not sure I'd book on these as they seem to rarely operate to schedule.

I was on a US 767 flying out of SJU in January and the same thing happened but the cpt came on and said it was due to the NAV system. They never fixed it after we landed so we took an extensive route over land (I think it was DR, Bahamas and the coast of Florida), so what should have been a 3:05 flight to PHL turned into 4:20 in the air once we took off the second time...

For example, I pulled the stats on YVR-HNL, and of the 82 operations year-to-date, only 5 had a delay of greater than 30 minutes. Sounds pretty good to me.

A further review of flightstats shows:
AC 49 67% of total flights delayed for average delay 73 minutes
AC 57 43% of total flights delayed for average delay 49 minutes
AC 47 51% of total flights delayed for average delay 45 minutes.
I know averages are not always a true representation and I certainly want safety as "job 1" (partucularly since I take AC 47 & 49 3 or 4 times a year.
However, these three Hawaiian flights do seem to have a good share of delays and several this year alone have experienced delays of many hours. I often wonder if the maintenance folk put the aircraft on these trips at the bottom of their "to do" list (the arguement being they are only vacaction flights etc). From my view point AC must be making very good money on Hawaii given virtually all flights are full and (with some exceptions) the tickets are very expensive.

ac-yul & AC854...
Is one of you checking departure stats and the other arrival stats?
Seasonal headwinds and deicing can change an on time departure to a late arrival.
It's easy for the crew to release the brakes at the gate to show an ontime departure. (I mean to get the payroll clock ticking.)
Harder to do at the arrival end.

Now I don't know what flightstats' criteria are for measuring delays; I glanced at AC047 YVR-HNL for 2011 so far and I see less than 10 delays that are delayed for 30 mins or more out of 84 operations so far - certainly not the 51% that's showing above. There are some 15-20 minutes delays but that're not uncommon for a flight of this duration with winter headwinds as I also see some flights that have landed as much as 50 mins early. If they're using 'average' delays, then one also needs to remember if there's a flight with a significant delay (as we did on Jan 4 - 10+ hours) then that would drag the average up overall. All I am trying to say is let's put things in perspective and not assume the whole route is bad or aircraft are unreliable based on a a few delays out of the hundreds of flights that we operate daily.
