Airport; Procedure
We were given vectors prior to the arc for the ILS DME 2 RWY 10. We were at 180 knots; Flaps 15/15; and north of final approach course. After a vector to join the LOC; ATC cleared us for the approach and for a descent. Shortly after beginning the descent in V/S; we received the 'Terrain Ahead' alert followed by the 'PULL UP; TERRAIN!' At this point I firewalled the throttles; disconnected the autopilot; and began an aggressive climb toward the min safe altitude. We coordinated with ATC; leveled off; and received vectors back to final.
While on vectors to intercept the localizer for the MMGL ILS DME 2 RWY 10 MMGL approach control told us to descend to 6500 FT from 7500 FT (?). First Officer is the PF and Captain is PM. We were inside 13 miles of the MMGL airport and considered our position to be clear of the hill (7480 FT) vertically as well as the surrounding terrain at around 11 miles out while on the final vector to the ILS course. Shortly after the start of the descent we received an EGPWS call out of 'Terrain Ahead' while in IMC conditions. Within 3-5 seconds of the initial alert we received a command alert of 'Pull Up Terrain.' First Officer executed the CFIT maneuver immediately and we climbed up toward the highest MSA altitude of 11;700. We notified Approach about the CFIT go around and they repeatedly asked if it was due to traffic! We repeated several times the cause for the go around was a terrain alert in the cockpit due to the ATC assigned altitude. During the climb; passing 10;500 FT we were given vectors for another ILS approach to RWY 10 again and the ensuing approach and landing were uneventful.
Flight crew on a radar vector to the ILS DME 2 RWY 19 at MMGL experienced an EGPWS terrain warning during descent to 6500 feet at ATC direction. The flying First Officer immediately abandoned the approach using maximum power and climbed to the MSA. The second approach was uneventful.
