Airworthiness Directive · Amendment 39-13903 · Raytheon Aircraft Company, Model 390, Premier 1 Airplanes
Raytheon Aircraft Company, Model 390, Premier 1 Airplanes
This AD affects the following airplane model and serial numbers that are certificated in any category: Model 390 Premier I, Serials RB-1, RB-4 through RB-84, RB-87 through RB-90, RB-92 through RB-96, RB-99 through RB-101, and RB-103 through RB-106.
The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company, Model 390, Premier 1 airplanes. This AD requires you to inspect the routing and security of the left and right main landing gear (MLG) squat switch wire harness installations for damage, repair any damage or replace components, and reinstall the squat switch wire harness. We are issuing this AD to prevent damage to the wire harnesses, which could result in loss of pressurization, loss of transponder responses to interrogations, and failure of other systems utilizing air/ground status signals. This failure could lead to loss of control of the airplane.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) For airplanes prior to serial number RB-100 with Kit 390-8103-0001 installed, and for airplanes with production installation of the plunger-style squat switch, serial numbers RB-100, RB-101, and RB-103 through RB-106, perform the following actions: | Inspect within 30 days after the effective date of this AD, January 18, 2005. If damage is found, replace the switch bracket prior to further flight after the inspection | Follow Raytheon Aircraft Company Service Bulletin SB 32-3678, dated June 2004. |
| (i) Visually inspect the squat switch bracket for corrosion or cracking (damage). | ||
| (ii) If damage is found, replace the switch bracket with part number 390-810008-0003/-0004. | ||
| (2) All airplanes affected by this AD perform the following actions: (i) Inspect MLG wiring harness service loop for excessive length in air mode (strut extended). The radius of the wire harness service loop should not exceed that of the brake hose service loop. The radius of the brake hose loop should not exceed the radius of the tire. If the length is excessive in air mode, correct in accordance with Raytheon Aircraft Company Service Bulletin SB 32-3678, dated June 2004. (ii) Remove and relocate tie straps and M85052/1-8 mounting clamp. (iii) Perform the landing gear operational test. | Within 30 days after the effective date of this AD, January 18, 2005 | Follow Raytheon Aircraft Company Service Bulletin SB 32-3678, dated June 2004. |
