Narrative:

We were cleared to taxi from taxiway oscar short of tango to runway 28L. Being somewhat unfamiliar with the taxiways at pit we missed the hard left turn back onto taxiway tango. Proceeding on taxiway papa crossing runway 32-14. I feel that the taxi instructions that were given were vague and unmonitored. Creating a system breakdown. This situation could have been avoided by greater vigilance on everyone's part. Once airborne and still preoccupied with this situation we climb through our assigned altitude of 5000 ft. By approximately 400 ft my solution to this problem would be a reevaluation of current far part 135 flight and duty limitations. Our trip this day consisted of 6 cycles, 11 hours duty, 7.1 block time. I might add that this transpired on the last leg of the trip sequence. Supplemental information from acn 201557. Backgnd: when it rains, it pours. Both pilots were tired, having spent the previous night in a noisy motel, and were not rested for the AM55 show time. There was no opportunity to stop and eat during the entire trip, except for a couple of candy bars, from show time until these incidents took place. Further, it was the last leg of the trip and we felt extra pressure to be at the destination airport on time so the new crew would have time to do a proper acceptance and depart on time. Plus, the controller did not follow our progress. All of these are warning flags to slow down and be more methodical even at the expense of schedule. Thinking back on this domino-like cascade of oversights and mistakes, I am grateful that the results were not more serious. I have learned a valuable lesson.

Title: RWY INCURSION. UNAUTH UNCOORD RWY XING ENTRY.

Narrative: WE WERE CLRED TO TAXI FROM TAXIWAY OSCAR SHORT OF TANGO TO RWY 28L. BEING SOMEWHAT UNFAMILIAR WITH THE TAXIWAYS AT PIT WE MISSED THE HARD L TURN BACK ONTO TAXIWAY TANGO. PROCEEDING ON TAXIWAY PAPA XING RWY 32-14. I FEEL THAT THE TAXI INSTRUCTIONS THAT WERE GIVEN WERE VAGUE AND UNMONITORED. CREATING A SYS BREAKDOWN. THIS SITUATION COULD HAVE BEEN AVOIDED BY GREATER VIGILANCE ON EVERYONE'S PART. ONCE AIRBORNE AND STILL PREOCCUPIED WITH THIS SITUATION WE CLB THROUGH OUR ASSIGNED ALT OF 5000 FT. BY APPROX 400 FT MY SOLUTION TO THIS PROBLEM WOULD BE A REEVALUATION OF CURRENT FAR PART 135 FLT AND DUTY LIMITATIONS. OUR TRIP THIS DAY CONSISTED OF 6 CYCLES, 11 HRS DUTY, 7.1 BLOCK TIME. I MIGHT ADD THAT THIS TRANSPIRED ON THE LAST LEG OF THE TRIP SEQUENCE. SUPPLEMENTAL INFO FROM ACN 201557. BACKGND: WHEN IT RAINS, IT POURS. BOTH PLTS WERE TIRED, HAVING SPENT THE PREVIOUS NIGHT IN A NOISY MOTEL, AND WERE NOT RESTED FOR THE AM55 SHOW TIME. THERE WAS NO OPPORTUNITY TO STOP AND EAT DURING THE ENTIRE TRIP, EXCEPT FOR A COUPLE OF CANDY BARS, FROM SHOW TIME UNTIL THESE INCIDENTS TOOK PLACE. FURTHER, IT WAS THE LAST LEG OF THE TRIP AND WE FELT EXTRA PRESSURE TO BE AT THE DEST ARPT ON TIME SO THE NEW CREW WOULD HAVE TIME TO DO A PROPER ACCEPTANCE AND DEPART ON TIME. PLUS, THE CTLR DID NOT FOLLOW OUR PROGRESS. ALL OF THESE ARE WARNING FLAGS TO SLOW DOWN AND BE MORE METHODICAL EVEN AT THE EXPENSE OF SCHEDULE. THINKING BACK ON THIS DOMINO-LIKE CASCADE OF OVERSIGHTS AND MISTAKES, I AM GRATEFUL THAT THE RESULTS WERE NOT MORE SERIOUS. I HAVE LEARNED A VALUABLE LESSON.
