[We were] flying into Quito on the RNAV RNP Runway 35 approach. VMC conditions; I was pilot not flying. Airplane was in VNAV and LNAV and the autopilot was engaged. We were told to report DEVAS inbound. I had my head down at DEVAS while tuning the radio frequency to make the report to Tower. I heard the warning 'Terrain... pull up.' As I was looking up the Captain pulled back on the yoke and the warning went away. I looked outside and at the instruments and did not see any indication that we were too low. We were above glide path and the runway and ground lights were visible. The Captain resumed the approach and we landed without incident.
I was the pilot flying conducting the approach beginning with at PATCO into Quito. We were kept a little high over PATCO but were re-established on the VNAV path and on speed shortly after the fix. Inbound from ANBUR or speed ranged from 170-175 KTS with flaps 10. About 3 mile from DEVAS we selected Gear Down and selected flaps 30 about 1 mile from DEVAS. Just inside of DEVAS we received a Terrain Warning followed by a Pull Up command. We were on VNAV Path; on speed; and above the VASI with the runway in sight in clear conditions. As I pulled up the aircraft went into CWS pitch as the warnings ceased. Only green terrain indications were noted at the aircraft symbol. With the warnings gone and prior to me initiating the CFIT recovery maneuver we were still in a position to safely land so with the concurrence of the First Officer we did so without event.
An Air Carrier crew reported conducting the escape maneuver in response to an EGPWS TERRAIN PULL UP alert at 10;400 FT on the SEQU RNP RNAV Runway 35 just inside DEVAS even though the aircraft was in VNAV PATH above the VASI.
