Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2008–0584; Directorate 

Identifier 2007–NM–315–AD; Amendment 

39–15639; AD 2008–17–01] 

RIN 2120–AA64 

Airworthiness Directives; Dornier 

Model 328–100 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 AvCraft Dornier 

Model 328–100 airplanes. That AD 

currently requires modifying the 

electrical wiring of the fuel pumps; 

installing insulation at the hand flow 

control and shut-off valves, and other 

components of the environmental 

control system; and installing markings 

at fuel wiring harnesses. The existing 

AD also requires revising the 

Airworthiness Limitations section of the 

Instructions for Continued 

Airworthiness to incorporate new 

inspections of the fuel tank system. This 

new AD replaces the flight-hour-based 

threshold for conducting certain initial 

inspections, with an 8-year threshold. 

This AD results from fuel system 

reviews conducted by the manufacturer. 

We are issuing this AD to reduce the 

potential of ignition sources inside fuel 

tanks, which, in combination with 

flammable fuel vapors, could result in 

fuel tank explosions and consequent 

loss of the airplane. 

DATES: This AD becomes effective 

September 17, 2008. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of September 17, 2008. 

On July 29, 2005 (70 FR 36470, June 

24, 2005), the Director of the Federal 

Register approved the incorporation by 

reference of AvCraft Service Bulletin 

SB–328–00–445, including Price 

Information Sheet, dated August 23, 

2004; and Dornier Temporary Revision 

ALD–080, dated October 15, 2003.

SUPPLEMENTARY INFORMATION: 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 2005–13–24, amendment 

39–14161 (70 FR 36470, June 24, 2005). 

The existing AD applies to all AvCraft 

Dornier Model 328–100 airplanes. That 

NPRM was published in the Federal 

Register on May 22, 2008 (73 FR 29720). 

That NPRM proposed to continue to 

require modifying the electrical wiring 

of the fuel pumps; installing insulation 

at the hand flow control and shut-off 

valves, and other components of the 

environmental control system; and 

installing markings at fuel wiring 

harnesses. That NPRM also proposed to 

continue to require revising the 

Airworthiness Limitations section (ALS) 

of the Instructions for Continued 

Airworthiness to incorporate new 

inspections of the fuel tank system. That 

NPRM also proposed to replace the 

flight-hour-based threshold for 

conducting certain initial inspections, 

with an 8-year threshold. 

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. 

Change to ‘‘Later Revisions of the ALD’’ 

Paragraph of the NPRM 

We removed all references to the use 

of ‘‘later revisions’’ of the applicable 

service information from this AD to be 

consistent with FAA policy. This 

change will not increase the economic 

burden on any operator, nor will it 

increase the scope of the AD, since we 

may consider approving the use of later 

revisions of the service bulletin as an 

alternative method of compliance with 

this AD, as provided by paragraph (j) of 

this AD. 

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 16 airplanes of 

U.S. registry. The actions that are 

required by AD 2005–13–24 and 

retained in this AD take about 70 work 

hours per airplane, at an average labor 

rate of $80 per work hour. Required 

parts cost about $14,118 per airplane. 

Based on these figures, the estimated 

cost of the currently required actions is 

$315,488, or $19,718 per airplane. 

The new required action to revise the 

ALS takes about 1 work hour per 

airplane. Based on these figures, the 

estimated cost of the new actions 

specified in this AD for U.S. operators 

is $1,280, or $80 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 


hsrobinson on PROD1PC76 with RULES
47028 Federal Register / Vol. 73, No. 157 / Wednesday, August 13, 2008 / Rules and Regulations 

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.

certain operator maintenance documents to 

include inspections. Compliance with these 

inspections is required by 14 CFR 91.403(c). 

For airplanes that have been previously 

modified, altered, or repaired in the areas 

addressed by these inspections, the operator 

may not be able to accomplish the 

inspections described in the revisions. In this 

situation, to comply with 14 CFR 91.403(c), 

the operator must request approval for an 

alternative method of compliance according 

to paragraph (j) of this AD. The request 

should include a description of changes to 

the required inspections that will ensure the 

continued operational safety of the airplane.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Bombardier Aerospace has completed a 

system safety review of the aircraft fuel 

system against fuel tank safety standards 

* * *. 

[A]ssessment showed that supplemental 

maintenance tasks [inspections of fuel tank 

bonding jumpers, wiring harnesses, and 

drain valve components, among other items 

and actions; and applicable corrective 

actions] are required to prevent potential 

ignition sources within the fuel system, 

which could result in a fuel tank explosion. 

* * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

September 17, 2008. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 17, 2008.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (NPRM) to amend 

14 CFR part 39 to include an AD that 

would apply to the specified products. 

That supplemental NPRM was 

published in the Federal Register on 

May 1, 2008 (73 FR 23995). That 

supplemental NPRM proposed to 

correct an unsafe condition for the 

specified products. The MCAI states: 

Bombardier Aerospace has completed a 

system safety review of the aircraft fuel 

system against fuel tank safety standards 

introduced in Chapter 525 of the 

Airworthiness Manual through Notice of 

Proposed Amendment (NPA) 2002–043. The 

identified non-compliances were then 

assessed using Transport Canada Policy 

Letter No. 525–001, to determine if 

mandatory corrective action is required. 

The assessment showed that supplemental 

maintenance tasks [inspections of fuel tank 

bonding jumpers, wiring harnesses, and 

drain valve components, among other items 

and actions; and applicable corrective 

actions] are required to prevent potential 

ignition sources within the fuel system, 

which could result in a fuel tank explosion.
