ACTION: Final rule. dwashington3 on PROD1PC60 with RULES AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for certain Boeing Model 727 airplanes. This AD requires among other actions, installing new ground fault interrupter (GFI) relays for the main fuel tanks and the auxiliary fuel tank pumps. This AD also VerDate Nov<24>2008 14:27 Feb 26, 2009 Jkt 217001 requires revising the FAA-approved maintenance program to incorporate new Airworthiness Limitations for the GFI of the boost pumps and for the uncommanded on system for the auxiliary fuel tank pumps. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an electrical fault in the fuel pump system, which might cause a connector or end cap to burn through and a subsequent fire or explosion inside the fuel pump or wing spar area. We are also issuing this AD to prevent uncommanded operation of the auxiliary fuel tank pumps, which can cause them to run dry. This condition will increase pump temperature and could supply an ignition source to fumes in the fuel tank, which can result in a consequent fire or explosion. DATES: This AD is effective April 3, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 3, 2009.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 8851 directive (AD) that would apply to certain Boeing Model 727 airplanes. That NPRM was published in the Federal Register on October 7, 2008 (73 FR 58509). That NPRM proposed to require, among other actions, installing new ground fault interrupter (GFI) relays for the main fuel tanks and the auxiliary fuel tank pumps. This AD also requires revising the FAA-approved maintenance program to incorporate new Airworthiness Limitations for the GFI of the boost pumps and for the uncommanded on system for the auxiliary fuel tank pumps. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Support for the NPRM Boeing concurs with the contents of the NPRM. General Comment Disagreeing With NPRM Another commenter, Ralph Pascale, asserts that the current configuration of the boost pump circuits is adequate and does not need to be changed. The commenter feels that by installing the GFIs on the boost pumps according to the NPRM, there could be a condition where during a loss of all generators due to thunderstorms, electrical power is lost to the boost pumps and the possibility of the GFI tripping due to high voltage (getting hit by lightning) will prevent the boost pumps from supplying boosted pressure when electrical power is re-established, causing a triple flameout. We infer that the commenter is requesting that we withdraw the NPRM. We do not concur. Loss of all generators resulting in loss of all boost pumps is a rare event, even without GFI installed for the boost pumps. The GFI has been tested for lightning threat to a level that is higher than the worst-case lightning threat that a Model 727 airplane would typically experience. Therefore, the risk to the boost pumps has not increased. We have not changed this final rule in light of the comment. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD will affect 199 airplanes of U.S. registry. The following table provides the estimated E:\FR\FM\27FER1.SGM 27FER1 8852 Federal Register / Vol. 74, No. 38 / Friday, February 27, 2009 / Rules and Regulations costs for U.S. operators to comply with this AD.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Boeing Model 727 airplanes. This AD requires among other actions,
installing new ground fault interrupter (GFI) relays for the main fuel
tanks and the auxiliary fuel tank pumps. This AD also requires revising
the FAA-approved maintenance program to incorporate new Airworthiness
Limitations for the GFI of the boost pumps and for the uncommanded on
system for the auxiliary fuel tank pumps. This AD results from fuel
system reviews conducted by the manufacturer. We are issuing this AD to
prevent an electrical fault in the fuel pump system, which might cause
a connector or end cap to burn through and a subsequent fire or
explosion inside the fuel pump or wing spar area. We are also issuing
this AD to prevent uncommanded operation of the auxiliary fuel tank
pumps, which can cause them to run dry. This condition will increase
pump temperature and could supply an ignition source to fumes in the
fuel tank, which can result in a consequent fire or explosion.

DATES: This AD is effective April 3, 2009.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of April 3,
2009.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
certain Boeing Model 727 airplanes. That NPRM was published in the
Federal Register on October 7, 2008 (73 FR 58509). That NPRM proposed
to require, among other actions, installing new ground fault
interrupter (GFI) relays for the main fuel tanks and the auxiliary fuel
tank pumps. This AD also requires revising the FAA-approved maintenance
program to incorporate new Airworthiness Limitations for the GFI of the
boost pumps and for the uncommanded on system for the auxiliary fuel
tank pumps.

Comments

We gave the public the opportunity to participate in developing
this AD. We considered the comments received.

Support for the NPRM

Boeing concurs with the contents of the NPRM.

General Comment Disagreeing With NPRM

Another commenter, Ralph Pascale, asserts that the current
configuration of the boost pump circuits is adequate and does not need
to be changed. The commenter feels that by installing the GFIs on the
boost pumps according to the NPRM, there could be a condition where
during a loss of all generators due to thunderstorms, electrical power
is lost to the boost pumps and the possibility of the GFI tripping due
to high voltage (getting hit by lightning) will prevent the boost pumps
from supplying boosted pressure when electrical power is re-
established, causing a triple flameout.
We infer that the commenter is requesting that we withdraw the
NPRM. We do not concur. Loss of all generators resulting in loss of all
boost pumps is a rare event, even without GFI installed for the boost
pumps. The GFI has been tested for lightning threat to a level that is
higher than the worst-case lightning threat that a Model 727 airplane
would typically experience. Therefore, the risk to the boost pumps has
not increased. We have not changed this final rule in light of the
comment.

Conclusion

We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD as proposed.

Costs of Compliance

We estimate that this AD will affect 199 airplanes of U.S.
registry. The following table provides the estimated

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

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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.

Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

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

Sec. 39.13 [Amended]

0
2. The FAA amends Sec. 39.13 by adding the following new AD:

2009-05-03 Boeing: Amendment 39-15827. Docket No. FAA-2008-1065;
Directorate Identifier 2008-NM-126-AD.

Effective Date

(a) This airworthiness directive (AD) is effective April 3,
2009.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Boeing Model 727, 727C, 727-100, 727-
100C, 727-200, and 727-200F series airplanes, certificated in any
category; as identified in Boeing Alert Service Bulletin 727-
28A0128, dated April 4, 2008.

Note 1: This AD requires revisions to certain operator
maintenance documents to include new 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 (AMOC)
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.

Unsafe Condition

(d) This AD results from fuel system reviews conducted by the
manufacturer. We are issuing this AD to prevent an electrical fault
in the fuel pump system, which might cause a connector or end cap to
burn through and a subsequent fire or explosion inside the fuel pump
or wing spar area. We are also issuing this AD to prevent
