The MAYSA3 RNAV SID is unusual in that there is a top altitude of 8;000 feet; but in the initial climb instructions it says to cross GOALY at or below 9;000 feet. In the routing instructions it also says to maintain 8;000 feet all the way through the transition. The clearance given said climb via the SID. I don't think I have seen another SID with a top altitude below the first hold down altitude. It seems possible that aircrew might mistakenly climb to 9;000 feet if cleared to climb via the SID. I'm trying to figure out a situation where the 9;000 feet would come into play if the top altitude is always 8;000 feet; just a bit confusing. I am submitting this ASAP for your consideration to help avoid deviations. No deviation has occurred.
