What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) C-fqpk, a PA-30 enroute from waterloo regional airport (ykf) to teterboro (teb) reported icing at 6000 feet over huegonot VOR, and was cleared to descend. During the descent, the left engine began surging, and eventually failed. The engine was restarted and the aircraft continued to teb. The PA-30 airplane flight manual prohibits the use of the tip tanks during descent, however, the pilot/owner of the aircraft stated he had descended while using tip tanks on prior flights with no problems.
