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.

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–
