Narrative:
The pre departure clearance we received with our final paperwork at departure time had an error of the departure SID and altitude (ie, in the route section it showed 'cleared as filed with a pomona departure'). However, at the bottom, it said prd 5 departure and an initial altitude of 7000 ft! When we contacted socal departure, we were flying the pomona departure, as the controller questioned our altitude readback of 7000 ft and cleared us to 14000 ft -- the correct altitude for the departure. Callback conversation with reporter revealed the following information: reporter first officer verified aircraft as B727 and because he didn't have a copy of the pre departure clearance, couldn't verify exactly how it read. He thought that the upper part of the pre departure clearance was bracketed by stars and said cleared as filed with a pomona 6 departure. At the bottom of the pre departure clearance, it read prado 5 departure and maintain 7000 ft. Both the captain and first officer thought the first clearance was correct and didn't question it prior to departure. The departure controller called their attention to the correct clearance. Either there was, in fact, an error in the pre departure clearance or they were confused about the change to it.
Original NASA ASRS Text
Title: B727 ACFT PRIOR TO DEP FLC RECEIVED PDC PRINTOUT AND THOUGHT IT WAS IN ERROR BECAUSE THERE WERE 2 ROUTINGS. ONE THAT SAID 'CLRED AS FILED...POM 6 DEP,' THEN AT THE BOTTOM A REVISION SAID PRADO 5 DEP AND 7000 FT. FLC CHOSE THE FIRST AND APPARENTLY THE WRONG ONE BECAUSE THE DEP CTLR REVISED THEIR ALT AND DEP.
Narrative: THE PDC WE RECEIVED WITH OUR FINAL PAPERWORK AT DEP TIME HAD AN ERROR OF THE DEP SID AND ALT (IE, IN THE RTE SECTION IT SHOWED 'CLRED AS FILED WITH A POMONA DEP'). HOWEVER, AT THE BOTTOM, IT SAID PRD 5 DEP AND AN INITIAL ALT OF 7000 FT! WHEN WE CONTACTED SOCAL DEP, WE WERE FLYING THE POMONA DEP, AS THE CTLR QUESTIONED OUR ALT READBACK OF 7000 FT AND CLRED US TO 14000 FT -- THE CORRECT ALT FOR THE DEP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR FO VERIFIED ACFT AS B727 AND BECAUSE HE DIDN'T HAVE A COPY OF THE PDC, COULDN'T VERIFY EXACTLY HOW IT READ. HE THOUGHT THAT THE UPPER PART OF THE PDC WAS BRACKETED BY STARS AND SAID CLRED AS FILED WITH A POMONA 6 DEP. AT THE BOTTOM OF THE PDC, IT READ PRADO 5 DEP AND MAINTAIN 7000 FT. BOTH THE CAPT AND FO THOUGHT THE FIRST CLRNC WAS CORRECT AND DIDN'T QUESTION IT PRIOR TO DEP. THE DEP CTLR CALLED THEIR ATTN TO THE CORRECT CLRNC. EITHER THERE WAS, IN FACT, AN ERROR IN THE PDC OR THEY WERE CONFUSED ABOUT THE CHANGE TO IT.
