essna: 172R; Failed Oil Pressure Sensor

<h3><font color = "blue">Cessna: 172R; Failed Oil Pressure Sensor; ATA 7931</font></h3>
<p>“The aircraft was making an approach,” states a mechanic, “and had oil splash on the windshield. The pilot made a full stop and taxied back to the ramp. Oil pressure and temperature stayed in the ‘green.' Upon investigation it was found the cause of the oil leak was the sensor-oil pressure (Hobbs switch; P/N 83278).... The sensor had failed internally and the oil was coming from around the prongs inside the connector area. Probable cause—bad design.” </p>
<p><em>(A search of the FAA Service Difficulty Reporting System data base revealed five separate reports for this specific part number.) </em></p>

Re: essna: 172R; Failed Oil Pressure Sensor

My Cessna T182-T is in for annual and needs part number 83278 replaced (AD) before they release it.  Does anyone know where I can find one?  They say backordered until end of September at least... help please
