IFR to KGRE; requested the VOR/DME A approach to KGRE. Center advised a NOTAM applied; but I assumed the approach still authorized. I understood clear to maintain 2;400 until established and cleared for approach; but on reflection uncertain that clearance was for VOR/DME A. Approach was normal with landing at KGRE.Received field NOTAMs at KGRE on preflight briefing; but did not discover FDC 5/6341 until checking NOTAMs online later.
Pilot reported of not discovering a NOTAM that applied to his flight into airport. Pilot was unclear to what type of approach he was cleared for.
