[Docket No. 93-NM-69-AD; Amendment 39-8886; AD 94-08-14]

 

Airworthiness Directives; Corporate Jets Limited Model BAe 125-
1000A Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all Corporate Jets Model BAe 125-1000A series airplanes, 
that requires replacement of the white `EMERG CONTCTRS' annunciator 
screen on roof panel `CG' of the flight deck with an amber screen. This 
amendment is prompted by a report that the annunciator screen currently 
installed on these airplanes is not a color that would alert the flight 
crew that corrective action may be necessary. The actions specified by 
this AD are intended to ensure that the flight crew is alerted to 
conditions when standby electrical power is not available.

DATES: Effective May 20, 1994.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of May 20, 1994.

ADDRESSES: The service information referenced in this AD may be 
obtained from Corporate Jets, Inc., 22070 Broderick Drive, Sterling, 
Virginia 20166. This information may be examined at the Federal 
Aviation Administration (FAA), Transport Airplane Directorate, Rules 
Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of 
the Federal Register, 800 North Capitol Street NW., suite 700, 
Washington, DC.

FOR FURTHER INFORMATION CONTACT: Stephen Slotte, Aerospace Engineer, 
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (206) 
227-2797; fax (206) 227-1320.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to all Corporate Jets Model BAe 125-
1000A series airplanes was published in the Federal Register on 
November 29, 1993 (58 FR 62557). That action proposed to require 
replacement of the white `EMERG CONTCTRS' annunciator screen on roof 
panel `CG' of the flight deck with an amber screen.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public. 
The FAA has determined that air safety and the public interest require 
the adoption of the rule as proposed.
    The FAA estimates that 13 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 1 work hour per 
airplane to accomplish the required actions, and that the average labor 
rate is $55 per work hour. Required parts will be supplied by the 
manufacturer to operators at no cost. Based on these figures, the total 
cost impact of the AD on U.S. operators is estimated to be $715, or $55 
per airplane.
    The total cost impact figure discussed above is based on 
assumptions that no operator has yet accomplished any of the 
requirements of this AD action, and that no operator would accomplish 
those actions in the future if this AD were not adopted.
    The regulations adopted herein will not have substantial direct 
effects 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. Therefore, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under 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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.
