39–9195; AD 95–08–06]

Airworthiness Directives; Raytheon

Corporate Jets Models DH/BH/HS/BAe

125–1A to –700A Series Airplanes; BAe

125–800A Airplanes; and Hawker 800

Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Raytheon

Corporate Jets Models DH/BH/HS/BAe

125–1A to –700A series, BAe 125–800A,

and Hawker 800 series airplanes, that

requires replacement of the existing

standby static inverter with an inverter

that incorporates a circuit board

assembly sealed with a conformal

coating. This amendment is prompted

by reports of failure of the standby static

inverter caused by electrical shorting

from moisture condensing on the

printed circuit boards (PCB), due to

aberrations in the PCB conformal

coating. The actions specified by this

AD are intended to prevent malfunction

of the standby static inverter due to

exposure to moisture caused by

inadequate insulation coating of the

circuit board assembly. Malfunction or

failure of the standby static inverter,

when its use is necessary, could result

in the loss of electric power for certain

equipment critical to safety of flight.

DATES: Effective May 18, 1995.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of May 18,

1995.

ADDRESSES: The service information

referenced in this AD may be obtained

from Raytheon Corporate Jets, Inc., 3

Bishops Square, St. Albans Road West,

Hatfield, Hertfordshire AL109NE,

United Kingdom. This information may

be examined at the Federal Aviation

Administration (FAA), Transport

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 certain Raytheon

Corporate Jets Models DH/BH/HS/BAe

125–1A to –700A series airplanes, BAe

125–800A airplanes, and Hawker 800

airplanes was published in the Federal

Register on January 18, 1995 (60 FR

3592). That action proposed to require

replacement of the existing standby

static inverters with a printed circuit

board assembly that is properly sealed

with a conformal coating.

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.

For clarification purposes, the FAA

has revised the references to the DH/

BH/HS/BAe 125 models throughout this

rule to add the model designator ‘‘A’’ to

the series numbers. Models DH/BH/HS/

BAe 125–1A through –700A are the

models that are type certificated for

operation in the United States and,

accordingly, affected by this AD action.

• After careful review of the available

data, the FAA has determined that air

safety and the public interest require the

adoption of the rule with the clarifying

change previously described. The FAA

has determined that this change will

neither increase the economic burden

on any operator nor increase the scope

of the AD.

The FAA estimates that 450 airplanes

of U.S. registry will be affected by this

AD, that it will take approximately 4

work hours per airplane to accomplish

the required actions, and that the

average labor rate is $60 per work hour.

Required parts will cost approximately

$410 per airplane. Based on these

figures, the total cost impact of the AD

on U.S. operators is estimated to be

$292,500, or $650 per airplane.

The total cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of
Federal Register / Vol. 60, No. 74 / Tuesday, April 18, 1995 / Rules and Regulations 19351

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.
