What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Reported engine out, vectored for surveillance approach to runway, radar contact was lost. (.4)the pilot was flying at night, over lake Michigan, in IFR conditions when he informed Milwaukee approach that the engine had quit. He was 20 miles northeast of Milwaukee. He was able to glide about 12 miles before impacting the water. The body of the pilot and airplane were recovered about two months after the accident. Examination of the engine driven fuel pump revealed that a 3/4 inch rubber washer was restricting the fuel flow through the outflow valve of the pump. Airworthiness directive (AD) 93-11-11 states that the remanufactured fuel pump was to be replaced before the next flight in order 'to prevent disruption of fuel flow to the engine, which can result in a loss of engine power.' The AD had not been complied with. (-23) unknown at this time, aircraft or pilot have not been recovered from lake Michigan.
