2007-12-21 Hawker Beechcraft Corporation (Type Certificate No. A00010WI previously held by Raytheon Aircraft Company): Amendment 39-15099; Docket No. FAA-2007-28251; Directorate Identifier 2007-CE- 049-AD.
Effective Date
(a) This AD becomes effective on June 20, 2007.
Affected ADs
(b) This AD supersedes AD 2006-26-08; Amendment 39-14866.
Applicability
(c) This AD affects the following Model 390 airplanes that are certificated in any category:
(1) Serial numbers RB-1 through RB-49 that have Field Service Kit 390-9100 installed; and
(2) Serial numbers RB-50 through RB-209.
Unsafe Condition
(d) This AD is the result of continuing failures of the hydraulic pump outlet tubes and the need to incorporate improved design. We are issuing this AD to prevent failure of the hydraulic pump outlet tube and consequent leaking of hydraulic fluid. Such leakage could result in a fire. There is also a risk of loss of hydraulic system functions including normal gear extensions, speed brakes, roll spoilers, lift dump, and normal brakes.
Compliance
(e) To address this problem, you must do the following, unless already done:
Actions
Compliance
Procedures
(1) Visually inspect the hydraulic pump outlet tube for evidence of chafing, excessive vibration, wear, deterioration, or hydraulic fluid leakage, as follows:
(i) For the left-hand (LH) engine: Remove the clamp, perform the inspection, and replace the clamp with a new one as specified in Raytheon Mandatory Service Bulletin No. SB 29-3771 after each inspection.
(ii) For the right-hand (RH) engine: Perform the inspection. Removal and replacement of the clamps are not necessary.
Initially at whichever of the following occurs first and thereafter at intervals not to exceed 25 hours time-in-service (TIS) until the kits required in paragraph (e)(4) of this AD are incorporated:
(A) Within the next 25 hours TIS after December 28, 2006 (the effective date of AD 2006-26-08); or(B) At the next inspection required by AD 2006-02-51.
Inspect following Raytheon Safety Communique No. 267, dated January 2006. Raytheon Safety Communique No. 267, dated January 2006, addresses the LH engine. Use the same inspection procedures for the RH engine hydraulic pump outlet tube (P/N 390-580037). Remove and replace the clamp (LH only) following Raytheon Mandatory Service Bulletin No. SB 29-3771, dated January, 2006.
(2) Replace the hydraulic pump outlet tube, part number (P/N) 390-580035 (or FAA-approved equivalent) for the LH engine or P/N 390-580037 (or FAA-approved equivalent) for the RH engine.
Each and every time any of the following occurs until the kits required in paragraph (e)(4) of this AD are incorporated.
(i) Prior to further flight after any inspection required in paragraph (e)(1) of this AD where evidence of chafing, excessive vibration, wear, deterioration, or hydraulic fluid leakage is found; and
(ii) Within 1 hour TIS following identification of an intended or unintended engine operation with the hydraulic shutoff valve closed.
