Narrative:
On the rdu, nc, STAR - argal 4 arrival (argal.ARGAL4) commercial (10-2) at argal intersection it states: 'cross at 10000 ft at 250 KTS in a southwest operation.' if a pilot followed these instructions (altitude) without a specific ATC clearance to 10000 ft, after being cleared to fly the STAR, he would be in violation of the FARS, with possible catastrophic results. Some pilots may miss the statement 'turbojet vertical navigation planning information' under the route identify, as it does not appear on all stars. The crossing restr should include the word 'expect' as found at hopewell and franklin vors, in order to standardize the chart. Callback conversation with reporter revealed the following information: talked to a representative of the commercial chart manufacturer. He said the error occurred because the FAA form 7700 they received was in error. The chart is already being corrected and will be received by 'weekly' subscribers on the 10/15 revision. However, the 'biweekly' subscribers will get it on the 10/22 revision.

Narrative: ON THE RDU, NC, STAR - ARGAL 4 ARR (ARGAL.ARGAL4) COMMERCIAL (10-2) AT ARGAL INTXN IT STATES: 'CROSS AT 10000 FT AT 250 KTS IN A SW OP.' IF A PLT FOLLOWED THESE INSTRUCTIONS (ALT) WITHOUT A SPECIFIC ATC CLRNC TO 10000 FT, AFTER BEING CLRED TO FLY THE STAR, HE WOULD BE IN VIOLATION OF THE FARS, WITH POSSIBLE CATASTROPHIC RESULTS. SOME PLTS MAY MISS THE STATEMENT 'TURBOJET VERT NAV PLANNING INFO' UNDER THE RTE IDENT, AS IT DOES NOT APPEAR ON ALL STARS. THE XING RESTR SHOULD INCLUDE THE WORD 'EXPECT' AS FOUND AT HOPEWELL AND FRANKLIN VORS, IN ORDER TO STANDARDIZE THE CHART. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: TALKED TO A REPRESENTATIVE OF THE COMMERCIAL CHART MANUFACTURER. HE SAID THE ERROR OCCURRED BECAUSE THE FAA FORM 7700 THEY RECEIVED WAS IN ERROR. THE CHART IS ALREADY BEING CORRECTED AND WILL BE RECEIVED BY 'WEEKLY' SUBSCRIBERS ON THE 10/15 REVISION. HOWEVER, THE 'BIWEEKLY' SUBSCRIBERS WILL GET IT ON THE 10/22 REVISION.
