Airworthiness Directive · Amendment 39-14459 · Raytheon Aircraft Company Model 390 Airplanes
Raytheon Aircraft Company Model 390 Airplanes
Superseded. A later AD replaced this one: AD 2006-26-08. Comply with the one in force.
This AD affects the following Model 390 airplanes that are certificated in any category:
(1) Serial numbers RB-1 through RB-49 that are equipped with Kit 390-9100 that incorporates part number (P/N) 390-580035-0001 (or FAA-approved equivalent part number);
(2) Serial numbers RB-50 through RB-141; and
(3) Serial numbers RB-143 through RB-148.
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company Model 390 airplanes. This AD contains the same information as emergency AD 2006-02-51 and publishes the action in the Federal Register. This AD requires you to visually inspect the hydraulic tube assembly (P/N 390-580035-0001 or P/N 390- 580035-0005) and the clamp (P/N MS21919WCJ6 or P/N MS21919WCJ7) (or FAA-approved equivalent part numbers), as specified in the service information; replace the clamp at each inspection; replace the hydraulic tube assembly immediately if any of the problems identified in the service bulletin are found; and report the results of each inspection or replacement to the FAA. This AD results from failure of the hydraulic tube assembly, which caused in-flight loss of hydraulic fluid. We are issuing this AD to prevent failure of the hydraulic tube assembly and consequent leaking of hydraulic fluid. This failure could result in loss of hydraulic system functions and risk of fire because of flammable fluid leakage in the engine nacelle and lead to loss of control of the airplane.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Perform a one-time visual inspection of the hydraulic tube assembly and clamp using Raytheon Safety Communique No. 267, dated January 2006. Perform repetitive detailed inspections thereafter per Raytheon Mandatory Service Bulletin No. SB 29-3771, dated January, 2006 (i) The tube assembly part number is P/N 390-580035-0001 or P/N 390-580035-0005) (ii) The clamp part number is P/N MS21919WCJ6 or P/N MS21919WCJ7 | Visually inspect before further flight after February 2, 2006 (the effective date of this AD), except for those who received emergency AD 2006-02-51, issued January 19, 2006, unless already done. Perform the detailed inspection within 10 hours time-in-service (TIS) after February 2, 2006 (the effective date of this AD), except for those who received emergency AD 2006-02-51, issued January 19, 2006, unless already done. Inspect thereafter at intervals not to exceed 50 hours TIS. You may perform the detailed inspection before further flight instead of the visual inspection. Emergency AD 2006-02-51 contained the requirements of this amendment and became effective immediately upon receipt | For the visual inspection, use Raytheon Safety Communique No. 267, dated January, 2006. For the detailed inspections, use the procedures in Raytheon Mandatory Service Bulletin No. SB 29-3771, dated January, 2006. |
| (2) Replace the hydraulic tube assembly (P/N 390-580035-0001 or P/N 390-580035-0005) and the clamp (P/N MS21919WCJ6 or P/N MS21919WCJ7) (or FAA-approved equivalent part numbers) with new P/N 390-580035-0001 or P/N 390-580035-0005 and P/N MS21919WCJ7 (or FAA-approved equivalent part numbers) or used parts | Replace the clamp at each inspection. Replace the tube assembly prior to further flight after any inspection where evidence of chafing, excessive vibration, wear, deterioration, or hydraulic fluid leakage is found. Refer to SB 29-3771, dated January, 2006 for acceptance/rejection information for the tube assembly | Follow the procedures in Raytheon Mandatory Service Bulletin No. SB 29-3771, dated January, 2006. |
| (3) Report the results to FAA of each inspection or replacement required in paragraphs (e)(1) and (e)(2) of this AD. The Office of Management and Budget (OMB) approved the information collection requirements contained in this regulation under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 and those following sections) and assigned OMB Control Number 2120-0056 | Within 10 days after the inspection or replacement or within 10 days after February 2, 2006 (the effective date of this AD), except for those who received emergency AD 2006-02-51, issued January 19, 2006, whichever occurs later | Include in your report the airplane serial number, the TIS of the airplane, and the TIS of the hydraulic tube assembly (P/N 390-580035-0001 or P/N 390-580035-0005) (or FAA-approved equivalent part number). E-mail/send your report to James P. Galstad, Propulsion Aerospace Engineer, ACE 116W, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Wichita, Kansas 67209; e-mail: james.galstad@faa.gov; telephone: 316-946-4135; facsimile: 316-946-4107. |
(4) Repositioning and Special Flight Permits: You may operate the airplane to return/position the airplane to a home base, hangar, maintenance facility, etc., for the purpose of doing only the visual inspection required by this AD.
(i) Operation of up to 10 hours time-in-service (TIS) is allowed for visual inspection repositioning flight(s) provided the flight(s) occur(s) no later than 30 days after January 19, 2006. This is a one-time provision.
(ii) Special flight permits are also allowed for the visual inspection required for this AD. Use the procedures in 14 CFR part 39.
(iii) Special flight permits are prohibited for the detailed inspections and possible replacements required by this AD.
(iv) For any repositioning flight or special flight permit for the visual inspection, you must operate with only the PILOT AND ANY ADDITIONAL FLIGHT CREW MEMBER REQUIRED FOR SAFE OPERATION.
(5) Disposal of Parts: Return replaced hydraulic tube assembly (P/N 390-580035-0001 or P/N 390-580035-0005) to Raytheon Aircraft Company per SB 29-3771 and dispose of the P/N MS21919WCJ6 or P/N MS21919WCJ6 clamp (or FAA-approved equivalent part numbers) following 14 CFR 43.10. Ship any replaced hydraulic tube and dispose of the clamp prior to returning the aircraft to service.
(6) Parts Manufacturer Approval (PMA): 14 CFR 21.303 allows for replacement parts through PMA. The phrase “or FAA-approved equivalent part number(s)” in this AD is intended to signify those parts that are PMA approved through identicality to the design of the part under the type certificate and replacement parts to correct the unsafe condition under PMA (other than identicality). If parts are installed that are identical to the unsafe parts, then the corrective actions of the AD affect these parts also. In addition, equivalent replacement parts to correct the unsafe condition under PMA (other than identicality) may also be installed provided they meet current airworthiness standards, which include those actions cited in 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.
