ACTION: Final rule; request for comments. wwhite on PROD1PC61 with RULES AGENCY: SUMMARY: 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.

SUPPLEMENTARY INFORMATION: Discussion What Events Have Caused This AD? The FAA received reports of four failures of the part number (P/N) 390– 580035–0001 hydraulic tube assembly located on the left engine assembly of Raytheon Model 390 airplanes. The failures resulted in in-flight loss of hydraulic fluid. The tube is installed between the hydraulic pump and the hydraulic pulsation damper and carries hydraulic pump output pressure. The latest failure occurred on an airplane with 83 hours time-in-service on the hydraulic tube assembly. On January 19, 2006, the FAA issued emergency AD 2006–02–51 to require PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 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. Why Is It Important To Publish This AD? The FAA found that immediate corrective action was required, that notice and opportunity for prior public comment were impracticable and contrary to the public interest, and that good cause existed to make the AD effective immediately by individual letters issued on January 19, 2006, to all known U.S. operators of the affected Raytheon Aircraft Company Model 390 airplanes. These conditions still exist, and the AD is published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective to all persons.

Authority for This Rulemaking wwhite on PROD1PC61 with RULES What Authority Does FAA Have for Issuing This Rulemaking Action? Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, VerDate Aug<31>2005 15:24 Feb 01, 2006 Jkt 208001 ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this AD. Regulatory Findings Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: ■ PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. Will This AD Impact Various Entities? We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. Will This AD Involve a Significant Rule or Regulatory Action? For the reasons discussed above, I certify that this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared a summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include ‘‘Docket No. FAA–2005–23221; Directorate Identifier 2005–CE–51–AD’’ in your request. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ 2006–02–51 Raytheon Aircraft Company: Amendment 39–14459; Docket No. FAA–2005–23221; Directorate Identifier 2005–CE–51–AD.

Airworthiness Directives; Raytheon Aircraft Company Model 390 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: This AD becomes effective on February 2, 2006. As of February 2, 
2006, the Director of the Office of the Federal Register approved the 
incorporation by reference of certain publications listed in the 
regulation. We must receive any comments on this AD by March 2, 2006.

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The FAA received reports of four failures of the part number (P/N) 
390-580035-0001 hydraulic tube assembly located on the left engine 
assembly of Raytheon Model 390 airplanes. The failures resulted in in-
flight loss of hydraulic fluid. The tube is installed between the 
hydraulic pump and the hydraulic pulsation damper and carries hydraulic 
pump output pressure.
    The latest failure occurred on an airplane with 83 hours time-in-
service on the hydraulic tube assembly.
    On January 19, 2006, the FAA issued emergency AD 2006-02-51 to 
require 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.

Why Is It Important To Publish This AD?

    The FAA found that immediate corrective action was required, that 
notice and opportunity for prior public comment were impracticable and 
contrary to the public interest, and that good cause existed to make 
the AD effective immediately by individual letters issued on January 
19, 2006, to all known U.S. operators of the affected Raytheon Aircraft 
Company Model 390 airplanes. These conditions still exist, and the AD 
is published in the Federal Register as an amendment to section 39.13 
of the Federal Aviation Regulations (14 CFR 39.13) to make it effective 
to all persons.

Authority for This Rulemaking

What Authority Does FAA Have for Issuing This Rulemaking Action?

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106 describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this AD.

Regulatory Findings

Will This AD Impact Various Entities?

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.

Will This AD Involve a Significant Rule or Regulatory Action?

    For the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2005-23221; Directorate Identifier 2005-CE-51-AD'' in your 
request.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the Federal Aviation Administration amends part 39 of the Federal 
Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2006-02-51 Raytheon Aircraft Company: Amendment 39-14459; Docket No. 
FAA-2005-23221; Directorate Identifier 2005-CE-51-AD.

When Does This AD Become Effective?

    (a) This AD becomes effective on February 2, 2006.

Are Any Other ADs Affected by This Action?

    (b) None.

What Airplanes Are Affected by This AD?

    (c) 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.

What Is the Unsafe Condition Presented in This AD?

    (d) This AD is the result of 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 the clamp 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.

What Must I Do To Address This Problem?

    (e) To address this problem, you must do the following:

    (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.
