Was on VFR pleasure flight from 16G to ptk via arb. The planned route skirts the outer limits of detroit class B airspace. Was flying VFR on top of broken layer. In the vicinity of yip, started descent through large hole in clouds. In the process of avoiding descent into clouds, I inadvertently turned east into the class B airspace by less than 2 mi. When I realized I had flown into the outer ring, I made an immediate 180 degree turn and quickly left the airspace. I was monitoring detroit approach frequency and heard of no traffic in the vicinity. I was descending through 4000 ft MSL at the time, which is the lower limit of the airspace. I saw no other aircraft nor did I hear any mention of my incursion on the frequency. When I landed, detroit TRACON requested a phone call. I spoke to the supervisor and explained what had happened, as well as the fact that I am familiar with the class B airspace and had never had this happen in the past 25 yrs of flying. In the future, I will either allow a wider margin or inform approach of my intentions and/or position.

Title: MO2J PLT, WHEN DSNDING THROUGH A BREAK IN THE CLOUDS, DETERMINES THAT HE HAS PENETRATED DTW CLASS B AIRSPACE. PLT TAKES IMMEDIATE ACTION TO VACATE PENETRATED AIRSPACE AND PROCEEDS TO DEST. PLT FAA TELEPHONE CONFERENCE APPARENTLY RESOLVES THE ISSUE.
Narrative: WAS ON VFR PLEASURE FLT FROM 16G TO PTK VIA ARB. THE PLANNED RTE SKIRTS THE OUTER LIMITS OF DETROIT CLASS B AIRSPACE. WAS FLYING VFR ON TOP OF BROKEN LAYER. IN THE VICINITY OF YIP, STARTED DSCNT THROUGH LARGE HOLE IN CLOUDS. IN THE PROCESS OF AVOIDING DSCNT INTO CLOUDS, I INADVERTENTLY TURNED E INTO THE CLASS B AIRSPACE BY LESS THAN 2 MI. WHEN I REALIZED I HAD FLOWN INTO THE OUTER RING, I MADE AN IMMEDIATE 180 DEG TURN AND QUICKLY LEFT THE AIRSPACE. I WAS MONITORING DETROIT APCH FREQ AND HEARD OF NO TFC IN THE VICINITY. I WAS DSNDING THROUGH 4000 FT MSL AT THE TIME, WHICH IS THE LOWER LIMIT OF THE AIRSPACE. I SAW NO OTHER ACFT NOR DID I HEAR ANY MENTION OF MY INCURSION ON THE FREQ. WHEN I LANDED, DETROIT TRACON REQUESTED A PHONE CALL. I SPOKE TO THE SUPVR AND EXPLAINED WHAT HAD HAPPENED, AS WELL AS THE FACT THAT I AM FAMILIAR WITH THE CLASS B AIRSPACE AND HAD NEVER HAD THIS HAPPEN IN THE PAST 25 YRS OF FLYING. IN THE FUTURE, I WILL EITHER ALLOW A WIDER MARGIN OR INFORM APCH OF MY INTENTIONS AND/OR POS.
