Airworthiness Directives; Fairchild

Aircraft, Inc. SA26, SA226, and SA227

Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes to

adopt a new airworthiness directive

(AD) that would apply to certain

Fairchild Aircraft, Inc. (Fairchild

Aircraft) SA26, SA226, and SA227

series airplanes. The proposedAD

would require you to modify the

negative torque sensing test system to

allow the igniters to automatically turn

when an engine senses low torque. The

proposed AD is the result of two

instances of a dual engine flameout on

the affected airplanes. The actions

specified by the proposed AD are

intended to prevent a dual engine

flameout on the affected airplanes by

providing a system that automatically

turns on the engine igniters when low

torque is sensed.A dual engine flameout

could result in failure of both engines

with consequent loss of control of the

airplane.

DATES: The Federal Aviation

Administration (FAA) must receive any

comments on this rule on or before July

27, 2001.

ADDRESSES: Submit comments in

triplicate to FAA,Central Region, Office

comments, you must include a selfaddressed, stamped postcard. On the

postcard, write ‘‘Comments to Docket

No. 2000–CE–36–AD.’’ We will date

stamp and mail the postcard back to

you.

Discussion

What events have caused this

proposed AD? Several occurrences of

dual-engine flameout on aircraft have

prompted FAA to examine the service

history of certain type-certificated

airplanes. Among those examined were

the Fairchild Aircraft SA26, SA226, and

SA227 series airplanes.

Our analysis reveals the following:

—Two incidents of dual-engine

flameout on Fairchild Aircraft SA227

series airplanes; and

—The incidents are unique to the

specific airplane configuration and

not the generic engine installation.

What are the consequences if the

condition is not corrected? A dual

engine flameout could result in failure

of both engines with consequent loss of

control of the airplane.

Relevant Service Information

Is there service information that

applies to this subject? Fairchild

Aircraft has issued the following service

bulletins:

Federal Register / Vol. 66, No. 104 / Wednesday, May 30, 2001 / Proposed Rules 29269

—Service Bulletin 26–74–30–048 (FA

Kit Drawing 26K82301), Revised:

April 13, 2000, which applies to

certain Model SA26–AT airplanes;

—Service Bulletin No. 226–74–003 (FA

Kit Drawing 27K82087), Issued:

March 21, 2000, which applies to

allSA226 series airplanes;

—Service Bulletin 227–74–003 (FA Kit

Drawing 27K82087), Issued: March

21, 2000, which applies to certain

Model SA227–TT airplanes; and

—Service Bulletin 227–74–001, Issued:

July 8,1986, which applies to certain

Models SA227–AT and SA227–AC

airplanes.

What are the provisions of this service

bulletin? The service bulletins specify

the incorporation of a kit that would

modify the negative torque sensing test

system to allow the igniters to

automatically turn when an engine

senses low torque.

The FAA’s Determination and an

Explanation of the Provisions of the

Proposed AD

What has FAA decided? After

examining the circumstances and

reviewing all available information

related to the incidents described above,

we have determined that:

—The unsafe condition referenced in

this document exists or could develop

on other Fairchild Aircraft SA26,

SA226, and SA227 series airplanes of

the same type design;

—The condition is unique to the

specific airplane configuration and

not the generic engine installation;

—The actions specified in the

previously-referenced service

information should be accomplished

on the affected airplanes; and

—AD action should be taken in order to

correct this unsafe condition.

What would the proposed AD require?

This proposed AD would require you to

incorporate the applicable kit as

specified in the previously-referenced

service information.

Cost Impact

How many airplanes would the

proposed AD impact? We estimate that

the proposed AD affects 259 airplanes in

the U.S. registry.

What would be the cost impact of the

proposed AD on owners/operators of the

affected airplanes? We estimate the

following costs to accomplish the

proposed modification:

Labor cost Parts cost Total cost per

airplane

Total cost on

U.S. operators

16 workhours × $60 per hour = $960 .......................... Ranges between $1,726 and $6,873 per airplane (we

will use a firgure of $4,000.

$4,960 $1,284,640

Compliance Time of the Proposed AD

What is the compliance time of the

proposed AD? The compliance time of

this proposed AD is within the next 6

calendar months after the effective date

of this proposed AD.

Why is the proposed compliance time

presented in calendar time instead of

hours time-in-service (TIS)? Although a

dual-engine flameout could only occur

on the affected airplanes during airplane

operation, the condition is not directly

related to airplane usage. The condition

exists on the airplanes regardless of

whether the airplane has accumulated

50 hours time-in-service (TIS) or 5,000

hours TIS.

The FAA has determined that the 6-

calendar-month compliance time:

—Gives all owners/operators of the

affected airplanes adequate time to

schedule and accomplish the actions

in this proposed AD; and

—Assures that the unsafe condition

referenced in this proposed AD will

be corrected within a reasonable time

period without inadvertently

grounding any of the affected

airplanes.

Regulatory Impact

Would this proposed AD impact

various entities? 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 proposed rule

would not have federalism implications

under Executive Order 13132.

Would this proposed AD involve a

significant rule or regulatory action? 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) 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 has been placed

in the Rules Docket. A copy of it may

be obtained by contacting the Rules

Docket at the location provided under

the caption ADDRESSES.

ACTION: Proposed rule.

SUMMARY: EPA is proposing to

redesignate the Pittsburgh-Beaver Valley

ozone nonattainment area (the

Pittsburgh Area) to attainment for the 1-

hour ozone National Ambient Air

Quality Standard (NAAQS). The

Pittsburgh area is comprised of

Allegheny, Armstrong, Beaver, Butler,

counties. The EPA is also proposing to

approve the maintenance plan,

submitted by the Pennsylvania

Department of Environmental Protection

(PADEP) on April 9, 2001, as a revision

to the Pennsylvania State

Implementation Plan (SIP). Approval of

the maintenance plan would put into

place a plan for maintaining the 1-hour

ozone standard for the next 10 years in

the Pittsburgh area. PADEP submitted a

1990 base year emissions inventory for

nitrous oxides (NOX) to EPA on March

22, 1996 and supplemented the

inventory on February 18, 1997. EPA is

also proposing to approve the 1990 NOX

base year inventory. Lastly, EPA is also

proposing to convert the limited

approval of Pennsylvania’s New Source

Review (NSR) program to full approval

throughout the Commonwealth, with

the exception of the 5-county

Pennsylvania portion of the

Philadelphia-Wilmington-Trenton

ozone nonattainment area where it will

retain its limited approval status until

that area has an approved attainment

demonstration for the 1-hour ozone

standard.
