During takeoff and departure, left engine cylinder head temperature showed high readings and excess movement. While en route, an altimeter setting caused me to disengage the altitude hold mode to descend 150 ft to return to 11000 ft. A sudden fluctuation in the gauge distraction me, and the controller called 1 min later and alerted me to my descent to 10600 ft. Immediate correction was initiated. A few mins later, another call from center alerted me to an easterly deviation from the airway (4 dots on the HSI/CDI), caused by failing to observe the airway changeover point for VOR frequencys. I was rather distraction by the cylinder head temperature fluctuations, and had not done enough recent flying to be up to PAR. Greater attention to all details of flight, and avoidance of excessive focus on one reading or instrument is needed, plus more time for currency proficiency.
Original NASA ASRS Text
Title: INST RATED PVT PLT OF AN SMT TWIN DSNDED FROM ASSIGNED ALT AND WANDERED OFF THE AIRWAY TRACK RESULTING IN ARTCC RADAR CTLR INTERVENTION TO REMIND RPTR OF HIS ERROR.
Narrative: DURING TKOF AND DEP, L ENG CYLINDER HEAD TEMP SHOWED HIGH READINGS AND EXCESS MOVEMENT. WHILE ENRTE, AN ALTIMETER SETTING CAUSED ME TO DISENGAGE THE ALT HOLD MODE TO DSND 150 FT TO RETURN TO 11000 FT. A SUDDEN FLUCTUATION IN THE GAUGE DISTR ME, AND THE CTLR CALLED 1 MIN LATER AND ALERTED ME TO MY DSCNT TO 10600 FT. IMMEDIATE CORRECTION WAS INITIATED. A FEW MINS LATER, ANOTHER CALL FROM CTR ALERTED ME TO AN EASTERLY DEV FROM THE AIRWAY (4 DOTS ON THE HSI/CDI), CAUSED BY FAILING TO OBSERVE THE AIRWAY CHANGEOVER POINT FOR VOR FREQS. I WAS RATHER DISTR BY THE CYLINDER HEAD TEMP FLUCTUATIONS, AND HAD NOT DONE ENOUGH RECENT FLYING TO BE UP TO PAR. GREATER ATTN TO ALL DETAILS OF FLT, AND AVOIDANCE OF EXCESSIVE FOCUS ON ONE READING OR INST IS NEEDED, PLUS MORE TIME FOR CURRENCY PROFICIENCY.
