NASA · Aviation Safety Reporting System
Air carrier pilot reported fatigue, gusts, flap overspeed and GPWS warning resulted in a CFTT event. Pilot reported during GPWS alert all terrain in sight and aircraft on glidepath.
What is ASRS?
The Aviation Safety Reporting System is NASA's voluntary, confidential, non- punitive incident-reporting system, established 1976. Pilots, controllers, dispatchers, and maintenance technicians file reports describing safety- relevant events. NASA de-identifies every report before adding it to the public database. Reports are not investigated by NASA, the FAA, or the NTSB — they represent the reporter's perspective.

Inside the final approach point on the RNAV (RNP) Z Runway 08 at ABQ airport at approximately 900 feet AGL, the autopilot was disengaged. The crew then experienced a gust of wind that increased indicated airspeed approximately 13 knots from the target speed of 166 knots. This exceeded the 30 flap placard airspeed of 175 knots, engaging the flap load relief function. Immediately after, the GPWS warning “Too Low, Terrain― sounded but the crew was able to visually verify terrain clearance from cultural lighting, then confirmed the aircraft was on the GPS glide path as well as having a good VASI (red over white) indication. These indications remained for the duration of the approach to touchdown. Power was reduced, the speed was brought back and the crew was able to recapture and verify stabilized approach criteria by 500 feet. The landing and ground operations were uneventful. A maintenance entry was made for the flap over-speed. Before descent, the approach had been thoroughly briefed and Runway 8 was specifically requested since the winds were directly down the runway (winds 070/20, gust 30). Decision points about wind shear and both ROW and ELP divert plans were briefed. The flaps 30 setting was deliberately chosen because gusty winds were a consideration. Cause: Fatigue. ABQ, final for Runway 8 inside 1,000 feet.
