On May 15, 2009 at approximately 1740Z I was communicating with PHL TRACON frequency 128.4. The transmissions I received on 128.4 were clear and were of adequate volume. The volume and clarity of 128.4 was as good at the transmissions I received from ZNY, ZOB, and PIT TRACON frequencies. When I was approximately 15 miles from my destination, the controller on 128.4 gave me a VFR descent from 7500MSL at pilot’s discretion. I acknowledged the instructions and began my descent to remain clear of the Class Bravo of PHL and to also remain clear of the clouds that were in the vicinity. KLOM (my destination) was reporting clear below 12,000, but the scattered to semi-broken clouds in the area had bases at approximately 4000MSL and tops of approximately 6000-6500MSL. The clouds seemed to run in lines approximately perpendicular to my heading which was 105°-110°, and I planned the descent to cross over one line of clouds and descend below the next line. As I was in my descent to KLOM I was handed off from 128.4 to 128.65, and made my call to the new controller.
Approach frequency 128.65 was very faint, and the clarity was very much lacking in comparison to all the previous frequencies I had been communicating on. While still clear of the Class Bravo I was descending through an opening in the cloud layer and maintaining adequate VFR cloud separation. The line of clouds ahead of me had a U-shape or saddle-shaped opening which would allow me to descend at my current rate and groundspeed without violating the Class Bravo airspace and maintaining VFR minima for cloud clearance. When I descended to 5,500MSL the controller on 128.65 made a very faint transmission to me which I believe stated, “Maintain VFR at or above 4,500.” I do not recall him giving clearance for me to enter the Bravo, which is 4000-7000 in that area, only the maintain VFR instructions. I responded with, “unable,” and stated that the scattered/broken cloud layer was from 3500AGL to 6000MSL.
There was a quick series of transmissions asking if I could accept an IFR clearance into KLOM, which I at first stated I could accept, but did not ask for. I did not have any low-enroute charts or approach plates with me as I was VFR, so I was hesitant to accept any IFR clearance. During this time I was remaining above 4500MSL, but was now unable to maintain VFR cloud clearances for the airspace outside the Bravo. I was in the saddle shaped cutout of the clouds, and any forward progress at this altitude would have penetrated the clouds in front of me, and at 150kts airspeed, any turn to the left or right would not have kept me 2000’ clear of the clouds. I estimate the distance between the clouds was 0.75 miles on either side of me. I then made a transmission to the PHL controller on 126.85 stating I was cancelling radar service, and switching to KLOM frequency. I then noticed that the message light was flashing on my GPS informing me that I was inside PHL’s Bravo airspace. I immediately descended to exit the Bravo and maintain VFR separation minima (the latter of which was accomplished because I was now inside the Bravo).
As I was descending, and not yet switched over to KLOM’s 123.0 frequency, I heard another aircraft state that they had me in sight and that I “looked like a dive-bomber” coming out of the clouds. I assume that the reason for the altitude restriction was to keep me clear of the IFR traffic that was in the clouds, or at least blocked from my view because of the clouds. I descended out of the Bravo, and was now maintaining Class E cloud separation. I completed my flight without further incident and landed at KLOM. All further transmissions on subsequent flights were normal, and acceptable.
How the problem arose: Controller issuing instructions I could not comply with.
Contributing factors: AWOS reporting clear within 10 miles of my position. The controller was unaware of actual sky and cloud conditions in the area. My selection of descent rate and point only provided one option to remain clear of clouds and airspace, and inadequate clarity and volume of transmissions from the controller.
How it was discovered: Notification of airspace penetration by GPS.
Corrective actions: Immediate descent to exit airspace, notification to controller, deviation from previous instructions.
