Narrative:
I was supplying pilot service on a piper malibu PA46-350P from pdx to rno to rdd and return to pdx. While climbing to 15000 ft (the assigned altitude), I had armed the altitude preselect for that altitude and experienced an in-flight emergency. The right fuel boost pump warning light illuminated and, while I was dealing with the checklist items trying to resolve the emergency, ZSE called to confirm my altitude assignment, and when I checked the altimeter, I was approximately 300 ft above the assigned 15000 ft and immediately applied corrective action to return to the assigned altitude and apologized to center, telling them that I had got off just a nickel and was returning to 15000 ft assigned. Shortly after leveling off at 15000 ft, I resolved the boost pump failure, but tried the altitude preselect several more times and it had failed on me and never worked again. I flew the remainder of the flight without further deviations. This was a classic example of getting preoccupied with an emergency in-flight and not monitoring altitude control. I had expected the altitude preselect to work and it did not.
Original NASA ASRS Text
Title: A PA46 MALIBU PLT CLBS 300 FT ABOVE HIS ASSIGNED ALT WHEN HE IS DISTR BY A FUEL PUMP WARNING LIGHT COMING S OF PDX, OR.
Narrative: I WAS SUPPLYING PLT SVC ON A PIPER MALIBU PA46-350P FROM PDX TO RNO TO RDD AND RETURN TO PDX. WHILE CLBING TO 15000 FT (THE ASSIGNED ALT), I HAD ARMED THE ALT PRESELECT FOR THAT ALT AND EXPERIENCED AN INFLT EMER. THE R FUEL BOOST PUMP WARNING LIGHT ILLUMINATED AND, WHILE I WAS DEALING WITH THE CHKLIST ITEMS TRYING TO RESOLVE THE EMER, ZSE CALLED TO CONFIRM MY ALT ASSIGNMENT, AND WHEN I CHKED THE ALTIMETER, I WAS APPROX 300 FT ABOVE THE ASSIGNED 15000 FT AND IMMEDIATELY APPLIED CORRECTIVE ACTION TO RETURN TO THE ASSIGNED ALT AND APOLOGIZED TO CTR, TELLING THEM THAT I HAD GOT OFF JUST A NICKEL AND WAS RETURNING TO 15000 FT ASSIGNED. SHORTLY AFTER LEVELING OFF AT 15000 FT, I RESOLVED THE BOOST PUMP FAILURE, BUT TRIED THE ALT PRESELECT SEVERAL MORE TIMES AND IT HAD FAILED ON ME AND NEVER WORKED AGAIN. I FLEW THE REMAINDER OF THE FLT WITHOUT FURTHER DEVS. THIS WAS A CLASSIC EXAMPLE OF GETTING PREOCCUPIED WITH AN EMER INFLT AND NOT MONITORING ALT CTL. I HAD EXPECTED THE ALT PRESELECT TO WORK AND IT DID NOT.
