Narrative:
Clearance to cross rlg at 14;000; inadvertently put 13;000 ft in CDU; immediately recognized error; corrected input to 14;000. Crossed rlg at 14;000 'on approach'; vti centered; 210 KTS. Two miles prior to voaxa; approach informed us; altitude at voaxa should be 13;800 (we were level 13;200); I verified altimeter; terrain display and vti. No glaring discrepancies stood out. Remainder of approach was uneventful. At gate reloaded approach into CDU and then noticed that when I placed 13;000 for rlg; altitude restriction of 13;800 ft at voaxa dropped out. I performed a thorough review of procedures for ege prior to signing in for trip; conducted a thorough briefing prior to descent. Once on approach was focused on terrain display; flight instruments; tracking and vti. This is an extremely insidious problem as nothing appeared amiss on any instruments; raw data or progress page 2. Suggest in addition to the recommended max speed of 220 KTS over rlg that a hard altitude of 14;000 ft be added to the approach if this crossing altitude is the norm. Contributing factors: several months since last flight into ege and fatigue. It is this individuals' opinion that far 117 has severely degraded safety as it relates to crew rest; particularly in light of monthly schedule projections approaching far maximums. Recently switching to daylight savings and losing an hour may have been another fatigue factor.
Original NASA ASRS Text
Title: B757 flight crew reports descending below the MEA between RLG and VOAXA on the LDA 25 approach to EGE. A crossing restriction of 13;800 at VOAXA was in the FMC but 13;000 was inadvertently set in the MCP for RLG and quickly corrected but this eliminated the VOAXA restriction; which was not detected.
