Narrative:

Pilot was cleared direct to the rober intersection (17 NM southwest of CCC) and issued a crossing restriction 15 NM northeast of rober at 12;000 and 250 KTS. The pilot read back was complete and correct. The PARCH1 STAR shows an expected altitude of rober at 9;000. The pilot descended thru 12;000. At 11;500 was re-cleared to maintain 12;000. The pilot stated the he 'needed to be rober at 9;000 feet.'retrain flight crews or change STAR expected altitudes to clear show that they are not assigned; but expected; altitudes. This is a by-product of descend via clearances. Maybe all stars should be named in a way that separates those with a descend via and those without; i.e. Stars that include a descend via should be changed from stars to pdtars (profile descent terminal arrival routes).

Title: B767-300 Flight Crew reports being cleared to pass abeam CCC at 12000 feet and 250 knots and cross ROBER at 9000 feet. The ZBW Controller involved believes the clearance was to expect ROBER at 9000 feet and sends the crew back up to 12000 feet.

The pilot read back was complete and correct. The PARCH1 STAR shows an expected altitude of ROBER at 9;000. The pilot descended thru 12;000. At 11;500 was re-cleared to maintain 12;000. The pilot stated the he 'needed to be ROBER at 9;000 feet.'Retrain flight crews or change STAR expected altitudes to clear show that they are not assigned; but expected; altitudes. This is a by-product of DESCEND VIA clearances. Maybe all STARs should be named in a way that separates those with a DESCEND VIA and those without; i.e. STARs that include a DESCEND VIA should be changed from STARs to PDTARs (Profile Descent Terminal Arrival Routes).
