Narrative:

Between approximately XA30 and XB30 local time on the date indicated I was conducting takeoffs and lndgs on runway 7 at N40 as well as local airwork consisting of commercial pilot maneuvers (stalls, steep turns, chandells, etc). On 2 occasions during the final approach phase of the flight, I executed low-altitude gars due to ground and airborne conflicts. The first go around was executed due to a number of deer that encroached upon the runway. The second involved a near miss with an ultralight aircraft. Following the roundout to landing and just prior to touchdown, an ultralight aircraft appeared turning final from a r-hand traffic pattern from an extremely low altitude (approximately 200 ft AGL) on the opposing runway (runway 25). I executed the go around successfully, sidestepping the runway to the north, avoiding the ultralight traffic and overflying a neighboring housing development at a lower than normal altitude, while climbing safely to pattern altitude. In executing the evasive action I had to bank sharply left and fly a ground track and an altitude that deviated from normal operating practice at N40, bringing potential concern by the residents due to the louder than normal aircraft noise, and seemingly abnormal flight attitude. Normally I would not do this, but the circumstances necessitated doing so. The ultralight was not using a radio and was not flying the standard l-hand pattern that is used at N40. A contributing factor in me not seeing the ultralight sooner, was likely due to my attention being partially focused on another potential incursion by animals on the runway.

Title: AN RV8 PLT HAS TO EXECUTE A GAR TO AVOID AN ULTRALIGHT ACFT THAT ENTERED A NON STANDARD PATTERN AND NO USE OF A RADIO.

Narrative: BTWN APPROX XA30 AND XB30 LCL TIME ON THE DATE INDICATED I WAS CONDUCTING TKOFS AND LNDGS ON RWY 7 AT N40 AS WELL AS LCL AIRWORK CONSISTING OF COMMERCIAL PLT MANEUVERS (STALLS, STEEP TURNS, CHANDELLS, ETC). ON 2 OCCASIONS DURING THE FINAL APCH PHASE OF THE FLT, I EXECUTED LOW-ALT GARS DUE TO GND AND AIRBORNE CONFLICTS. THE FIRST GAR WAS EXECUTED DUE TO A NUMBER OF DEER THAT ENCROACHED UPON THE RWY. THE SECOND INVOLVED A NEAR MISS WITH AN ULTRALIGHT ACFT. FOLLOWING THE ROUNDOUT TO LNDG AND JUST PRIOR TO TOUCHDOWN, AN ULTRALIGHT ACFT APPEARED TURNING FINAL FROM A R-HAND TFC PATTERN FROM AN EXTREMELY LOW ALT (APPROX 200 FT AGL) ON THE OPPOSING RWY (RWY 25). I EXECUTED THE GAR SUCCESSFULLY, SIDESTEPPING THE RWY TO THE N, AVOIDING THE ULTRALIGHT TFC AND OVERFLYING A NEIGHBORING HOUSING DEVELOPMENT AT A LOWER THAN NORMAL ALT, WHILE CLBING SAFELY TO PATTERN ALT. IN EXECUTING THE EVASIVE ACTION I HAD TO BANK SHARPLY L AND FLY A GND TRACK AND AN ALT THAT DEVIATED FROM NORMAL OPERATING PRACTICE AT N40, BRINGING POTENTIAL CONCERN BY THE RESIDENTS DUE TO THE LOUDER THAN NORMAL ACFT NOISE, AND SEEMINGLY ABNORMAL FLT ATTITUDE. NORMALLY I WOULD NOT DO THIS, BUT THE CIRCUMSTANCES NECESSITATED DOING SO. THE ULTRALIGHT WAS NOT USING A RADIO AND WAS NOT FLYING THE STANDARD L-HAND PATTERN THAT IS USED AT N40. A CONTRIBUTING FACTOR IN ME NOT SEEING THE ULTRALIGHT SOONER, WAS LIKELY DUE TO MY ATTN BEING PARTIALLY FOCUSED ON ANOTHER POTENTIAL INCURSION BY ANIMALS ON THE RWY.
