After contacting Millville FSS 4 times for WX info, the ACFT departed Lincoln Park, NY, at 1858 EDT with destination listed on the IFR FLT plan as Easton, MD. En route, the PLT diverted to Salisbury, MD, due to WX. After being cleared for the RWY 32 ILS, the ACFT turned northwest instead of southeast after crossing the VOR and descended to between 700 and 900 ft MSL while heading away from the ARPT. After being reoriented, the PLT was told to report at the COLBE LOM inbound. PLT proceeded to call COLBE when actually over Salisbury VOR. N81752 continued the APCH concluding by stating he was circling to land. The ACFT collided with trees on a northwest heading off the APCH end of RWY 32. The PLT had obtained his instrument rating 3 months prior and at that time had logged 34 instrument hours and 21 night hours. Post crash fire destroyed the majority of the fuselage, however, examination of the ACFT and engine did not reveal anything that would have affected normal operation.
