Narrative:

On may/wed/97, at XA30 local time my co-captain received an IFR clearance. The clearance read you are cleared via phl 6 departure maintain 6000 ft, cleared as filed, maintain FL390, 10 mins after departure and a squawk code. We proceeded to the runway for departure and departed runway 27L and departed on a 255 degree heading per the SID. The SID read maintain 5000 ft or lower altitude assigned by ATC. We leveled off at 6000 ft and contacted ATC. During the phase in contacting ATC, there was confusion in the departure frequencys during the departure phase. This delayed us in contacting departure. Once contact was made ATC advised us we were supposed to be at 5000 ft per ATC. Then ATC gave us instructions to turn right to 360 degrees and climb and maintain 15000 ft. We believe the discrepancy arose when copying the clearance. There was approximately 45 mins between the time we received the clearance and the time we departed. Phl 6 was mistaken for intermediate altitude. In short, the situation could probably be better improved if both pilots listen to the clearance and both copy the clearance.

Original NASA ASRS Text

Title: FLC OF AN LTT CPR LR60 OVERSHOT CLB ALT DURING A SID DEP DUE TO CONFUSION AS TO FOLLOWING THE SID OR THE TKOF DEP CLRNC.

Narrative: ON MAY/WED/97, AT XA30 LCL TIME MY CO-CAPT RECEIVED AN IFR CLRNC. THE CLRNC READ YOU ARE CLRED VIA PHL 6 DEP MAINTAIN 6000 FT, CLRED AS FILED, MAINTAIN FL390, 10 MINS AFTER DEP AND A SQUAWK CODE. WE PROCEEDED TO THE RWY FOR DEP AND DEPARTED RWY 27L AND DEPARTED ON A 255 DEG HDG PER THE SID. THE SID READ MAINTAIN 5000 FT OR LOWER ALT ASSIGNED BY ATC. WE LEVELED OFF AT 6000 FT AND CONTACTED ATC. DURING THE PHASE IN CONTACTING ATC, THERE WAS CONFUSION IN THE DEP FREQS DURING THE DEP PHASE. THIS DELAYED US IN CONTACTING DEP. ONCE CONTACT WAS MADE ATC ADVISED US WE WERE SUPPOSED TO BE AT 5000 FT PER ATC. THEN ATC GAVE US INSTRUCTIONS TO TURN R TO 360 DEGS AND CLB AND MAINTAIN 15000 FT. WE BELIEVE THE DISCREPANCY AROSE WHEN COPYING THE CLRNC. THERE WAS APPROX 45 MINS BTWN THE TIME WE RECEIVED THE CLRNC AND THE TIME WE DEPARTED. PHL 6 WAS MISTAKEN FOR INTERMEDIATE ALT. IN SHORT, THE SIT COULD PROBABLY BE BETTER IMPROVED IF BOTH PLTS LISTEN TO THE CLRNC AND BOTH COPY THE CLRNC.
