Narrative:

While hand flying the tecky one departure out of sjc on a 'climb via the SID' clearance; we received a level off and maintain 6000 feet MSL radio call from norcal departure. Upon doing so we reviewed our FMS and saw that rather than continuing a climb to 13;000 feet MSL; we were to level off at an intermediate altitude of 5000 feet MSL at the sptns RNAV waypoint. We deviated above the sptns altitude constraint. The issue arose from not setting 5000 feet MSL as our initial climb altitude and instead set 13000 feet MSL. We did not use vertical guidance on the SID thereby removing FMS vertical guidance and level off prompts from the flight director. Contributing to the issue was hand flying the aircraft and not selecting vertical guidance (VNAV) as the vertical flight cue. Corrective actions included compliance with ATC instruction; engaging the autopilot and reselecting an intermediate altitude on the altitude preselect system. The erroneous perception was to set 13;000 feet MSL as a top of SID altitude and not anticipate an intermediate altitude level off. The decision to hand fly; without VNAV guidance on a new SID affected human performance in terms of degraded situational awareness. A more thorough SID brief of the tecky one departure would have shown that 5000 feet MSL (like the sjc 9) is the first vertical constraint encountered and not the top of SID altitude of 13;000 feet MSL.

Original NASA ASRS Text

Title: G550 flight crew reports being cleared via TECKY1 RNAV departure from SJC to maintain 13000 feet. The crew does not notice nor do they enable the aircraft automation to notice an altitude restriction of 5000 feet at SPTNS. ATC assigns a level off at 6000 feet; once 5000 feet is exceeded.
