Airworthiness Directives; Short 

Brothers Model SD3 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to all Short Brothers 

Model SD3–30 and SD3–60 airplanes 

equipped with certain fire 

extinguishers. That AD currently 

requires replacement of the covers for 

fire extinguisher adapter assemblies that 

are installed on certain bulkheads with 

new covers that swivel to lock the 

extinguishers in place; and replacement 

of nozzles and triggers on these fire 

extinguishers with better fitting nozzles 

and stronger triggers. The existing AD 

also currently requires the installation 

of new fire extinguisher point placards 

and a revision of the airplane flight 

manual (AFM) to instruct the flightcrew 

in the use of the new covers for these 

adapter assemblies. This new AD also 

requires modification of the fire 

extinguishing point adapter assembly of 

the forward and aft baggage bays as 

applicable. This new AD also adds 

airplanes to the applicability. For these 

new airplanes, this new AD requires a 

revision to the AFM for instructions on 

using the new fire extinguisher adapter. 

This AD results from reports of 

individuals experiencing fire 

extinguishant blowback when the 

extinguishant discharges through the 

fire extinguishing point adapters. We 

are issuing this AD to prevent fire 

extinguishant blowback, which could 

result in injury to a person using the fire 

extinguisher in the event of a fire. 

DATES: Effective October 26, 2005. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of October 26, 2005. 

The Director of the Federal Register 

previously approved the incorporation 

by reference of certain other 

publications, as listed in the regulations, 

as of June 8, 1998 (63 FR 24387, May 

4, 1998).

SUPPLEMENTARY INFORMATION: 

Examining the Docket 

You may examine the AD docket on 

the Internet at http://dms.dot.gov or in 

person at the Docket Management 

Facility office between 9 a.m. and 5 

p.m., Monday through Friday, except 

Federal holidays. The Docket 

Management Facility office (telephone

level of the Nassif Building at the street 

address stated in the ADDRESSES section. 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 98–09–28, amendment 

39–10509 (63 FR 24387, May 4, 1998). 

The existing AD applies to all Short 

Brothers Model SD3–30 and SD3–60 

airplanes equipped with certain fire 

extinguishers. That NPRM was 

published in the Federal Register on 

June 3, 2005 (70 FR 32537). That NPRM 

proposed to continue to require the 

actions of AD 98–09–28. That NPRM 

also proposed to require modification of 

the fire extinguishing point adapter 

assembly of the forward and aft baggage 

bays as applicable. That NPRM also 

proposed to add airplanes to the 

applicability. For those new airplanes, 

that NPRM proposed to require a 

revision to the airplane flight manual 

(AFM) for instructions on using the new 

fire extinguisher adapter. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. No comments 

have been received on the NPRM or on 

the determination of the cost to the 

public. 

Explanation of Change to Applicability 

We have revised the applicability of 

this AD to identify model designations 

as published in the most recent type 

certificate data sheet for the affected 

models. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD with the change 

described previously. We have 

determined that this change will neither 

increase the economic burden on any 

operator nor increase the scope of the 

AD. 

Costs of Compliance 

This AD affects about 75 airplanes of 

U.S. registry. 

The actions that are required by AD 

98–09–28 and retained in this AD take 

about between 9 and 14 work hours per 

airplane, depending on airplane 

configuration, at an average labor rate of 

$65 per work hour. Required parts cost 

between $735 and $776 per airplane, 

depending on airplane configuration. 

Based on these figures, the estimated 

cost of the currently required actions is 

between $1,320 and $1,686 per airplane. 

The new actions take about 1 work 

hour per airplane, at an average labor 

rate of $65 per work hour. Based on 

these figures, the estimated cost of the 

new actions specified in this AD for 

U.S. operators is $4,875, or $65 per 

airplane. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

Section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701, 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We have determined that this AD will 

not have federalism implications under 

Executive Order 13132. This AD will 

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. 

For the reasons discussed above, I 

certify that this AD: 

(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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

Airworthiness Directives; The New 

Piper Aircraft, Inc., Models PA–28–160, 

PA–28–161, PA–28–180, and PA–28–

181 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA adopts a new 

airworthiness directive (AD) for certain 

The New Piper Aircraft, Inc. (Piper) 

Models PA–28–160, PA–28–161, PA–

28–180, and PA–28–181 airplanes that 

incorporate Petersen Aviation, Inc. 

Supplemental Type Certificate (STC) 

SA2660CE installed between April 20, 

1998, and April 1, 2005, and incorporate 

Petersen Aviation, Inc. Service Bulletin 

SB98–1. This AD requires you to replace 

the AN894–6–4 bushing screw thread 

expanders on the gascolator and 

bushing attached to the inlet of the top 

fuel pump with NAS1564–6–4J reducers 

and AN818–6 nuts. This AD results 

from reports of fuel leaks during the 

post STC installation tests. We are 

issuing this AD to prevent fuel fittings 

used in STC SA2660CE from leaking 

fuel in the engine compartment, which 

could result in an engine fire. This 

condition could lead to loss of control 

of the airplane.
