Narrative:

This was to be a VFR pleasure flight from yip to biv. Tower cleared me for takeoff on runway 23L and right turn. Shortly after takeoff, tower reported no transponder reply from my aircraft. I recycled the mode switch to standby and then back to altitude. Still focused on the transponder, I inadvertently let the climb continue past 2500 ft where I intended to level off until outside the detroit metropolitan horizontal class boundary. This was brought to my attention when tower called out gulfstream traffic about 2 1/2 mi, 11 O'clock position, landing at willow run, and suggested I descend to an altitude of 2800 ft. I spotted the gulfstream soon after the tower call and began a descent to pass below the path of the other aircraft. Then, considering the possible effect of its wake turbulence, I decided to match the gulfstream's altitude and turn left to pass behind it, maintaining visual separation until well clear. I was asked to call detroit metropolitan TRACON. The quality assurance manager told me there was a possible class B incursion. At my rate of climb, I had very little time between my intended leveloff altitude and the floor of class B. In the future, when taking off under class B, I will reduce rate of climb upon reaching a safe altitude above obstacles to provide more time to deal with other issues which might arise.

Title: A BE35 PLT RPTED CAUSING A CONFLICT WITH A GULFSTREAM DURING DEP FROM YIP.

Narrative: THIS WAS TO BE A VFR PLEASURE FLT FROM YIP TO BIV. TWR CLRED ME FOR TKOF ON RWY 23L AND R TURN. SHORTLY AFTER TKOF, TWR RPTED NO XPONDER REPLY FROM MY ACFT. I RECYCLED THE MODE SWITCH TO STANDBY AND THEN BACK TO ALT. STILL FOCUSED ON THE XPONDER, I INADVERTENTLY LET THE CLB CONTINUE PAST 2500 FT WHERE I INTENDED TO LEVEL OFF UNTIL OUTSIDE THE DETROIT METRO HORIZ CLASS BOUNDARY. THIS WAS BROUGHT TO MY ATTN WHEN TWR CALLED OUT GULFSTREAM TFC ABOUT 2 1/2 MI, 11 O'CLOCK POS, LNDG AT WILLOW RUN, AND SUGGESTED I DSND TO AN ALT OF 2800 FT. I SPOTTED THE GULFSTREAM SOON AFTER THE TWR CALL AND BEGAN A DSCNT TO PASS BELOW THE PATH OF THE OTHER ACFT. THEN, CONSIDERING THE POSSIBLE EFFECT OF ITS WAKE TURB, I DECIDED TO MATCH THE GULFSTREAM'S ALT AND TURN L TO PASS BEHIND IT, MAINTAINING VISUAL SEPARATION UNTIL WELL CLR. I WAS ASKED TO CALL DETROIT METRO TRACON. THE QUALITY ASSURANCE MGR TOLD ME THERE WAS A POSSIBLE CLASS B INCURSION. AT MY RATE OF CLB, I HAD VERY LITTLE TIME BTWN MY INTENDED LEVELOFF ALT AND THE FLOOR OF CLASS B. IN THE FUTURE, WHEN TAKING OFF UNDER CLASS B, I WILL REDUCE RATE OF CLB UPON REACHING A SAFE ALT ABOVE OBSTACLES TO PROVIDE MORE TIME TO DEAL WITH OTHER ISSUES WHICH MIGHT ARISE.
