On Wednesday, February 15, 2012, a Cessna 172 carrying three passengers crashed into Mount Si in North Bend, Washington. There were no survivors. The victims were, Rob Marshall Hill, Seth Dawson, and Liz Redling, according to The Seattle Times.
The Federal Aviation Administration (FAA) Preliminary Accident and Incident database, identifies the accident aircraft as N665SP, a C172, and states:
“AIRCRAFT CRASHED UNDER UNKNOWN CIRCUMSTANCES, THE 3 PERSONS ON BOARD WERE FATALLY INJURED, NEAR LITTLE SI MOUNTAIN, NORTH BEND, WA.”
The FAA Notice can be found here (Notice 1).
Prior to the crash, neighbors reportedly heard a “sputter, pop and an explosion,” as reported by The Seattle Times.
Our research indicates that in April of 2004, a Service Difficulty Report (SDR) was submitted to the FAA describing engine difficulty. The report described the following:
“ENGINE HAD VERY ROUGH AND RICH IDLE, COULD NOT ADJUST IDLE MIXTURE IAW AD. FUEL SERVO WAS INSTALLED ON A FRESH O/H ENGINE AND FUEL SERVE WAS ALSO FRESH FROM O/H. ENGINE WAS OPERATED AND LEAK CHECKED. AFTER .2 HOURS OF ENGINE OPERATION. FUEL SERVO BECAME ROUGH AND RICH. IDLER MIXTURE COULD NOT BE ADJUSTED.”

The National Transportation Safety Board (NTSB) has not yet posted a Preliminary Report, but we anticipate a preliminary report in the next 7-10 days. You can watch for both the Preliminary and Probable casuse report to be posted here, on our website, or at the NTSB website, here.
Witnesses described sputtering and popping sounds prior to the crash of the aircraft, according to The Seattle Times. An investigation should be performed to determine whether a defective engine or part may have contributed to the crash.
