Airworthiness Directives; AlliedSignal

Inc. Model TPE331 Series Turboprop

Engines

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to

AlliedSignal Inc. Model TPE331 series

turboprop engines. This proposal would

require removal of suspect fuel manifold

assemblies and replacement with

serviceable assemblies. This proposal is

prompted by an FAA investigation into

Hoses Unlimited’s repairs of TPE331

fuel manifolds, which were not

approved by the FAA. The actions

specified by the proposed AD are

intended to prevent fuel leakage at the

fuel manifold fittings, resulting in fuel

spraying on hot turbine components,

which could result in an engine fire.

DATES: Comments must be received by

March 23, 1998.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), New England

Region, Office of the Assistant Chief

Counsel, Attention: Rules Docket No.

to the Rules Docket by using the

following Internet address: ‘‘9-adengineprop@faa.dot.gov’’. All comments

must contain the Docket No. in the

subject line of the comment. Comments

Discussion

This proposed airworthiness directive

(AD) is applicable to AlliedSignal Inc.

Model TPE331–8, –10, –11 and –12

series turboprop engines with fuel

manifold, Part Number (P/N) 3102469–

1 or –2, repaired by Hoses Unlimited,

Inc. prior to November 11, 1995.

Following an FAA investigation into

Hoses Unlimited’s repairs of TPE331

fuel manifolds, which was not approved

by the agency, the FAA determined that

the repair processes were not consistent

and some manifolds were repaired using

procedures not approved and

substantiated by the FAA. The FAA

discovered that Hoses Unlimited

crimped fittings of unfamiliar

configuration with unsubstantiated

force causing excessive deformation of

the fitting and Teflon tube. Excessive

crimping of the tetraflourethelene hose

onto the fitting’s nipple causes reduced

fatigue resistance of the internal Teflon

tube. Reduced fatigue resistance may

lead to premature and unexpected

failure of the fuel hose. Although there

have been no reported incidents of fuel

leakage from fuel manifolds repaired by

Hoses Unlimited, this condition, if not

corrected, could result in fuel leakage of

the fuel manifold, resulting in fuel

spraying on hot turbine components,

which could result in an engine fire.

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

require removal of suspect fuel manifold

assemblies and replacement with

serviceable assemblies.

There are approximately 70 engines of

the affected design in the worldwide

fleet. The FAA estimates that 50 engines

installed on aircraft of U.S. registry

would be affected by this proposed AD,

that it would take approximately 5 work

hours per engine to accomplish the

proposed actions, and that the average

labor rate is $60 per work hour.

Required parts would cost

approximately $1,800 per engine. Based

on these figures, the total cost impact of

the proposed AD on U.S. operators is

estimated to be $105,000.

The regulations proposed herein

would 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

proposal would not have sufficient

federalism implications to warrant the

preparation of a Federalism Assessment.

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
Federal Register / Vol. 63, No. 13 / Wednesday, January 21, 1998 / Proposed Rules 3057

Flexibility Act. A copy of the draft

regulatory evaluation prepared for this

action is contained in the Rules Docket.

The Proposed Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration proposes to amend part

39 of the Federal Aviation Regulations

(14 CFR part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

AlliedSignal Inc.: Docket No. 97–ANE–47–

AD.

Applicability: AlliedSignal Inc. (formerly

Allied-Signal Aerospace Company, Garrett

Engine Division and Garrett Turbine Engine

Co.) Model TPE331–8, –10, –11 and –12

series turboprop engines with fuel manifold,

Part Number (P/N) 3102469–1 or –2, repaired

by Hoses Unlimited, Inc. prior to November

20, 1995. These engines are installed on but

not limited to Ayres S2R–G10; Cessna Model

441; Construcciones Aeronauticas, S.A.

(CASA) C–212 series; Dornier 228 series;

Fairchild SA226 and SA227 series; Jetstream

3101 and 3201 series; Mitsubishi MU–2B

series (MU–2 series); and Twin Commander

Aircraft Corp. Models 695 and 695A aircraft.

Note 1: This airworthiness directive (AD)

applies to each aircraft identified in the

preceding applicability provision, regardless

of whether it has been modified, altered, or

repaired in the area subject to the

requirements of this AD. For engines that

have been modified, altered, or repaired so

that the performance of the requirements of

this AD is affected, the owner/operator must

request approval for an alternative method of

compliance in accordance with paragraph (d)

of this AD. The request should include an

assessment of the effect of the modification,

alteration, or repair on the unsafe condition

addressed by this AD; and, if the unsafe

condition has not been eliminated, the

request should include specific proposed

actions to address it.

Compliance: Required as indicated, unless

accomplished previously.

To prevent fuel leakage of the fuel

manifold, resulting in fuel spraying on hot

turbine components, which could result in

an engine fire, accomplish the following:

(a) Check all fuel manifold identification

bands for P/Ns 3102469–1 or –2 and the

Hoses Unlimited, Inc. name, or review engine

and aircraft maintenance records and

purchase receipts to establish the origin and

repairs on all fuel manifolds. If records

indicate that fuel manifolds, P/Ns 3102469–

1 or –2, are not installed in an engine or that

Hoses Unlimited, Inc. has not been used as

a repair facility, no further AD action is

required.

(b) Remove from service all fuel manifolds

with the Hoses Unlimited, Inc. name and P/

Ns 3102469–1 or –2 and replace with a

serviceable fuel manifold in accordance with

the applicable AlliedSignal engine

maintenance manual, at first access to the

fuel manifold assembly, at the next engine

hot section inspection, or 3 years after the

effective date of this AD, whichever occurs

first.

(c) For the purposes of this AD, first access

to the fuel manifold is defined as any repair,

modification, removal, or testing of the fuel

manifold assembly or components of the fuel

manifold assembly.

(d) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager, Los

Angeles Aircraft Certification Office.

Operators shall submit their requests through

an appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, Los Angeles Aircraft

Certification Office.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this airworthiness directive,

if any, may be obtained from the Los Angeles

Aircraft Certification Office.

(e) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the aircraft to

a location where the requirements of this AD

can be accomplished.
