SUBJECT: Airworthiness Directive 2005-25-07
SUMMARY: The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company(Raytheon), Model 390, Premier 1 airplanes. For certain airplanes, this AD requires you (unless already done) to replace the plastic cover over the air conditioning motor module with a metalliccover and modify the air conditioning compressor motor module electromagnetic interferenceradiofrequency interference (EMI-RFI) filter located under the cover and reidentify the modulepart number. For all airplanes, the AD limits future installations of the cover for the air conditionerand the air conditioning compressor motor module. This AD results from reports that the plasticcover over the air conditioning motor module was found melted or burned and that theoverheating of the EMI-RFI filter assembly located under the cover caused this damage. We areissuing this AD to prevent the melting or burning of the plastic cover. The burning of the plasticcover could result in a fire.
