Narrative

DURING MY ARR IN A XCOUNTRY EVENT WITH OTHER SIMILAR TYPE ACFT (SINGLE ENG LOW WING) A RAPID DSCNT ON MY PART WAS NECESSARY TO ENTER THE ARR PATTERN. I OVERSHOT THE ALT BY QUITE A BIT THEN STARTED A SUBSEQUENT PULL UP TO ENTER THE TFC PATTERN AT WHICH TIME I ENCOUNTERED WHAT I THOUGHT WAS MODERATE WAKE TURB OF A PREVIOUS ACFT AT APPROX THE APEX OF MY CLB PITCH OF ABOUT 25-30 DEGS; AT WHICH TIME I RAPIDLY PULLED THE NOSE UP FURTHER IN AN ATTEMPT TO EXTRICATE MY ACFT FROM THE WAKE OF THE PREVIOUS ACFT WHICH RESULTED IN A VERY HIGH NOSE UP ATTITUDE OF APPROX 55-70 DEGS; AT WHICH TIME I WAS NO LONGER IN THE WAKE BUT AIRSPD WAS DECAYING VERY RAPIDLY. I THEN EXECUTED A NOSE HIGH RECOVERY BY ATTEMPTING TO ROLL TO THE NEAREST HORIZON AND I MAY HAVE ROLLED OVER 180 DEGS IN THIS ATTEMPT. MY ACFT WAS SUBSEQUENTLY ESTABLISHED ON A DSNDING R TURN TO REENTER THE TFC PATTERN WITH THE APPROPRIATE CALLS ON UNICOM 122.80 AND LANDED WITHOUT FURTHER INCIDENT NOR ANY DAMAGE TO ACFT OR PROPERTY. CONTRIBUTING FACTORS MAY HAVE BEEN CALM WINDS AND A TOO EXUBERANT OF A REACTION TO WAKE TURB ON MY PART. RELATIVELY LOW TIME IN THIS TYPE ACFT.
