Airworthiness Directive · Amendment 39-14400 · Raytheon Aircraft Company, Model 390, Premier 1 Airplanes
Raytheon Aircraft Company, Model 390, Premier 1 Airplanes
This AD applies to the following airplane models and serial numbers that are certificated in any category:
(1) Group 1: Raytheon Aircraft Company, Model 390, Premier 1 Airplanes, serial numbers RB-1, RB-4 through RB-101, RB-103 through RB-119, and RB-121, that have not replaced the plastic cover over the compressor motor module with a metallic one (part number (P/N) 390-555015-0001 or FAA-approved equivalent part number).
(2) Group 2: Raytheon Aircraft Company, Model 390, Premier 1 Airplanes, serial numbers RB-1, RB-4 through RB-101, RB-103 through RB-119, and RB-121, that have installed the metallic cover (P/N 390-555015-0001 or FAA-approved equivalent part number).
(3) Group 3: Raytheon Aircraft Company, Model 390, Premier 1 Airplanes, serial numbers RB-120 and RB-122 through RB-129.
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 metallic cover and modify the air conditioning compressor motor module electromagnetic interference-radio frequency interference (EMI-RFI) filter located under the cover and reidentify the module part number. For all airplanes, the AD limits future installations of the cover for the air conditioner and the air conditioning compressor motor module. This AD results from reports that the plastic cover over the air conditioning motor module was found melted or burned and that the overheating of the EMI-RFI filter assembly located under the cover caused this damage. We are issuing this AD to prevent the melting or burning of the plastic cover. The burning of the plastic cover could result in a fire.
What actions must I do to address this problem for Group 1 airplanes? To address this problem for Group 1 airplanes, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Air Conditioning Motor Module Cover Replacement: Replace the plastic cover over the air conditioning motor module with a new or fabricated metallic cover.
