Cpr light transport off phl climbing to 5000 ft. Thinking cleared 10000 ft and helping first officer to program long range navigation system, missed altitude alert at 4000 ft and caught the error at 5250 ft. Got to 5700 ft when the controller queried altitude and the cleared flight to 10000 ft.

Narrative:
On departure from phl we were cleared to 5000 ft. During the switch to departure control, probably in expectation of getting higher (we aren't normally held down on departure from the primary airport in the area), I got in my mind that we were cleared to 10000 ft. About that time, the other pilot was having difficulty programming the long range navigation and since I was under the impression that I had time to help out, I did so. Neither of us heard the audible altitude alert at 4000 ft, indicating 1000 ft to go. I heard the altitude alarm go off at 5250 ft, and by the time I got the climb arrested, we were at 5700 ft, at which time the controller asked us to verify our altitude, after which he immediately cleared us up to 10000 ft.

Title: CPR LTT OFF PHL CLBING TO 5000 FT. THINKING CLRED 10000 FT AND HELPING FO TO PROGRAM LONG RANGE NAV SYS, MISSED ALT ALERT AT 4000 FT AND CAUGHT THE ERROR AT 5250 FT. GOT TO 5700 FT WHEN THE CTLR QUERIED ALT AND THE CLRED FLT TO 10000 FT.
Narrative: ON DEP FROM PHL WE WERE CLRED TO 5000 FT. DURING THE SWITCH TO DEP CTL, PROBABLY IN EXPECTATION OF GETTING HIGHER (WE AREN'T NORMALLY HELD DOWN ON DEP FROM THE PRIMARY ARPT IN THE AREA), I GOT IN MY MIND THAT WE WERE CLRED TO 10000 FT. ABOUT THAT TIME, THE OTHER PLT WAS HAVING DIFFICULTY PROGRAMMING THE LONG RANGE NAV AND SINCE I WAS UNDER THE IMPRESSION THAT I HAD TIME TO HELP OUT, I DID SO. NEITHER OF US HEARD THE AUDIBLE ALT ALERT AT 4000 FT, INDICATING 1000 FT TO GO. I HEARD THE ALT ALARM GO OFF AT 5250 FT, AND BY THE TIME I GOT THE CLB ARRESTED, WE WERE AT 5700 FT, AT WHICH TIME THE CTLR ASKED US TO VERIFY OUR ALT, AFTER WHICH HE IMMEDIATELY CLRED US UP TO 10000 FT.
