repetitive inspections or possible

replacements. The FAA has no way of

determining how many main gear side

brace studs may need replacement or

how many repetitive inspections each

owner/operator may incur.

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 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

Discussion

The Federal Aviation Administration

(FAA) has received reports of failures of

Superior Air Parts, Inc. pistons, Part

Number (P/N) SA626992, installed on

Teledyne Continental Motors O–470

series engines. Investigation revealed

that an undetermined number of these

pistons had sharp edged casting lines in

the area of the piston pin boss that

could cause a stress riser. In 1981,

Superior Air Parts, Inc. introduced an

improved design piston, P/N SA640518,

recommended to replace piston, P/N

SA626992, at major overhaul. However,

the older model pistons, which are

subjected to high stresses due to heat,

firing pressures, and uneven forces

applied to the piston skirt as the

clearance between the piston and

cylinder barrel increases during service,

are being reused over more than one

overhaul cycle. This condition, if not

corrected, could result in engine power

loss, engine failure and loss of the

aircraft.

The FAA has reviewed and approved

the technical contents of Superior Air

Parts, Inc. Service Bulletin (SB) No. 93–

007, dated November 18, 1993, that

describes identification procedures for

determining the piston P/N, and

recommends replacement of all affected

pistons at major overhaul.

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 from service of Superior

Air Parts, Inc. pistons, P/N SA626992, at

the next access to the piston, top

overhaul, or major overhaul. The

affected pistons can be identified by

either a stamped-in P/N on the piston

dome (SA626992 or SA626992P15) or,

by a raised number (SA632932) along

one of the piston pin bosses on the

underside of the piston. The actions

would be required to be accomplished

in accordance with the SB described

previously.

The manufacturer has informed the

FAA that 5,585 pistons were shipped

between December 1976 and June 1981

and would be affected by this proposed

AD. The FAA estimates that it would

take approximately 2 work hours per

piston to accomplish the proposed

actions, and that the average labor rate

is $60 per work hour. Required parts

would cost approximately $156 per

piston. Based on these figures, the total

cost impact of the proposed AD on U.S.

operators is estimated to be $1,541,460.

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

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

To prevent piston failure, which can result

in engine power loss, engine failure and loss

of the aircraft, accomplish the following:

(a) At the next access to the piston, top

overhaul, or major overhaul after the effective

date of this airworthiness directive,

whichever occurs first, remove from service

pistons, P/N SA626992, and replace with a

serviceable part.

Note: The affected pistons can be identified

by either a stamped-in P/N on the piston

dome (SA626992 or SA626992P15) or, by a

raised number (SA632932) along one of the

piston pin bosses on the underside of the

piston.

(b) 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, Fort Worth

Special Certification Office. The request

should be forwarded through an appropriate

FAA Principal Maintenance Inspector, who

may add comments and then send it to the
