BEECH G35 — South Easton, MA

What happened

The instrument rated pilot was a volunteer pilot for a charity organization that connects pilots and aircraft owners with individuals in need of transportation primarily for medical purposes. The pilot was not instrument current. In addition, the charity did not verify instrument currency of volunteer pilots nor were they required to. After takeoff, the flight proceeded towards the destination airport on an instrument flight rules clearance and was vectored onto the downwind and base legs for sequencing. The pilot made two errors related to incorrect heading changes both of which were not immediately detected by the controller, but neither were significant. While on the base leg and approximately 1.5 miles west of the final approach course for runway 4R, the controller instructed the pilot to fly heading 060 degrees to intercept the final approach course. Radar data depicted a large radius turn towards the left, and the airplane flying through the final approach course. When the flight was approximately 1.6 miles east of the final approach course, the controller advised the pilot he had passed through the course and instructed him to turn to a heading of 010 degrees to re-intercept. Radar depicted a tight radius turn past the assigned heading, while the airplane descended below the assigned altitude of 3,000 feet. The airplane then turned to the north, then southeast with altitude deviations descending so low the controller issued several low altitude alerts. The airplane then entered a final descent, immerged from the base of clouds, and impacted into a parking lot. Examination of the engine, airframe, and avionics did not reveal any preimpact failures or malfunctions.
