Narrative:
While overflying the pit TCA at 9500 ft, I experienced a loss of engine power that caused me to descend to 7500 ft. The entire time while descending, my primary concern was to determine the cause of the power loss and did not have time to communicate to obtain clearance to enter the TCA. Apparently one of the things I changed caused the engine to recover and I immediately climbed out of the TCA. My best estimate was that I was in the TCA for approximately 6 mins. As I was climbing, I made an attempt to contact pit approach but was not successful. The engine continued to operate normally and I proceeded to my destination/landed.

Narrative: WHILE OVERFLYING THE PIT TCA AT 9500 FT, I EXPERIENCED A LOSS OF ENG PWR THAT CAUSED ME TO DSND TO 7500 FT. THE ENTIRE TIME WHILE DSNDING, MY PRIMARY CONCERN WAS TO DETERMINE THE CAUSE OF THE PWR LOSS AND DID NOT HAVE TIME TO COMMUNICATE TO OBTAIN CLRNC TO ENTER THE TCA. APPARENTLY ONE OF THE THINGS I CHANGED CAUSED THE ENG TO RECOVER AND I IMMEDIATELY CLBED OUT OF THE TCA. MY BEST ESTIMATE WAS THAT I WAS IN THE TCA FOR APPROX 6 MINS. AS I WAS CLBING, I MADE AN ATTEMPT TO CONTACT PIT APCH BUT WAS NOT SUCCESSFUL. THE ENG CONTINUED TO OPERATE NORMALLY AND I PROCEEDED TO MY DEST/LANDED.
