Airworthiness Directive · Amendment 39-14272 · Raytheon Aircraft Company Model 390 Airplanes
Raytheon Aircraft Company Model 390 Airplanes
This AD affects the following serial-numbered Model 390 airplanes that are certificated in any category:
The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) Model 390 airplanes. This AD requires you to replace the rudder pedal arm assemblies used in the rudder control system with parts of improved design. This AD results from reports of cracks found on the rudder pedal arm assemblies. We are issuing this AD to prevent failure of the rudder pedal arm assemblies caused by fatigue cracks. This failure could lead to loss of rudder control, loss of nose gear steering, and loss of toe brakes on the side on which the failure occurs.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Replace rudder pedal arm assemblies, part numbers (P/Ns) 390-524350-0001, 390-524350-0002, 390-524351-0001, and 390-524351-0002 with improved design parts, P/Ns 390-524400-0001, 390-524400-0002, 390-524401-0003, and 390-524401-0004 | Upon accumulating 300 hours time-in-service (TIS) or within 100 hours TIS after October 31, 2005 (the effective date of this AD), whichever occurs later, unless already done | Follow Raytheon Aircraft Company Mandatory Service Bulletin, SB 27-3691, Rev. 1, Revised: February, 2005, and the applicable maintenance manual. |
| (2) Do not install rudder pedal arm assemblies, P/Ns 390-524350-0001, 390-524350-0002, 390-524351-0001, and 390-524351-0002 | As of October 31, 2005 (the effective date of this AD) | Not applicable. |
Note: Replacing the rudder pedal arm assemblies following Raytheon Aircraft Company Mandatory Service Bulletin, SB 27-3691, Issued: October 2004, does not comply with this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
