AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

supersedure of an existing airworthiness

directive (AD), applicable to all

Raytheon Model DH.125–1A, –3A, and

–400A series airplanes, that currently

requires a one-time inspection to detect

scoring of the upper fuselage skin

around the periphery of the cockpit

canopy blister interface, and repair, if

necessary. This action would expand

the applicability of the existing AD to

include additional airplanes, and would

require that the actions be accomplished

in accordance with revised service

information for the newly added

airplanes. This AD is prompted by

additional reports indicating that

scoring has been detected on the upper

fuselage skin around the periphery of

the cockpit canopy blister interface. The

actions specified by the proposed AD

are intended to detect and correct

scoring of the upper fuselage skin

around the periphery of the cockpit

canopy blister interface, which could

result in reduced structural integrity of

the fuselage, and consequent cabin

depressurization.

Discussion

On April 24, 1997, the FAA issued

AD 97–09–12, amendment 39–10008 (62

FR 24013, May 2, 1997), applicable to

all Raytheon Model DH.125–1A, –3A,

and –400A series airplanes, to require a

one-time inspection to detect scoring of

the upper fuselage skin around the

periphery of the cockpit canopy blister

interface, and repair, if necessary. That

action was prompted by reports

indicating that scoring of the upper

fuselage skin had been detected in the

area. The requirements of that AD are

intended to detect and correct scoring of

the upper fuselage skin around the

periphery of the cockpit canopy blister

interface, which could result in reduced

structural integrity of the fuselage, and

consequent cabin depressurization.

Actions Since Issuance of Previous Rule

Since the issuance of that AD, the

FAA has received numerous reports

indicating that scoring has been

detected on the upper fuselage skin

around the periphery of the cockpit

canopy blister interface. Investigation

revealed that the scoring was caused by

the use of an improper tool (Exacto

knife), which was used to remove excess

sealant along the interface of the

fuselage skin and the cockpit canopy. In

light of these additional reports, the

FAA has determined that certain

Raytheon Model BH.125, DH.125, and

HS.125 series airplanes may be subject

to the identified unsafe condition.

Issuance of Revised Service

Information

The FAA has reviewed and approved

Raytheon Aircraft Service Bulletin SB

53–93, Revision 2, dated April 2000.

The inspection and repair procedures

described in this revision are identical

to those described in the original issue

of the service bulletin (which is

referenced in AD 97–09–12). However,

this revision expands the effectivity

listing to include additional airplanes

that are subject to the addressed unsafe

condition.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other products of this same

type design, the proposed AD would

supersede AD 97–09–12 to continue to

require a one-time inspection to detect

scoring of the upper fuselage skin

around the periphery of the cockpit

canopy blister interface, and repair, if

necessary. This action would expand

the applicability of the existing AD to

include additional airplanes that may

also be subjected to the identified

unsafe condition. The actions would be

required to be accomplished in

accordance with the service bulletin

described previously.

Cost Impact

There are approximately 290

airplanes of the affected design in the

worldwide fleet. The FAA estimates that

200 airplanes of U.S. registry would be

affected by this proposed AD.

The actions that are currently

required by AD 97–09–12 and retained

in this proposed AD would take

approximately 4 work hours per

airplane to accomplish, at an average

labor rate of $60 per work hour. Based

on these figures, the cost impact of the

currently required actions on U.S.

operators is estimated to be $48,000, or

$240 per airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the current or proposed requirements of

this AD action, and that no operator

would accomplish those actions in the

future if this AD were not adopted.

Regulatory Impact

The regulations proposed herein

would 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. Therefore,

it is determined that this proposal

would not have federalism implications

under Executive Order 13132.

For the reasons discussed above, I

certify that this proposed regulation (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) if

promulgated, 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 copy of the draft

regulatory evaluation prepared for this

action is contained in the Rules Docket.

A copy of it may be obtained by

contacting the Rules Docket at the
