DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. 2002-NE-42-AD; Amendment 39-13250; AD 2003-15-07]
RIN 2120-AA64
Airworthiness Directives; Honeywell International Inc. (Formerly
AlliedSignal) Model RE220 (RJ) Auxiliary Power Units
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
is applicable to Honeywell International Inc. (formerly AlliedSignal)
model RE220 (RJ) auxiliary power units (APUs) part number (P/N)
WE3800770-2. This amendment requires replacing the existing fuel
nozzles with new design fuel nozzles, making reidentification updates
to the APU identification plate, and operating the APU to perform a
visual inspection for fuel leaks. This amendment is prompted by reports
received by the FAA of cracks occurring in the existing APU fuel
nozzles leading to fuel leaks. The actions specified by the AD are
intended to prevent APU compartment fires and fuel vapor explosion.
DATES: Effective September 3, 2003.
ADDRESSES: Information regarding this action may be examined, by
appointment, at the Federal Aviation Administration (FAA), New England
Region, Office of the Regional Counsel, 12 New England Executive Park,
Burlington, MA.
FOR FURTHER INFORMATION CONTACT: Roger Pesuit, Aerospace Engineer, Los
Angeles Aircraft Certification Office, FAA, Transport Airplane
Directorate, 3960 Paramount Blvd., Lakewood, CA 90712-4137; telephone
(562) 627-5251, fax (562) 627-5210.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an AD that is
applicable to Honeywell International Inc. (formerly AlliedSignal)
Model RE220 (RJ) auxiliary power units was published in the Federal
Register on January 30, 2003. That action proposed to require replacing
the existing fuel nozzles, P/N WE3830486-2, with new design fuel
nozzles, P/N WE3830513-1, making reidentification updates to the APU
identification plate, and operating the APU to perform a visual
inspection for fuel leaks. The FAA also published a related AD, AD
2002-26-07, in the Federal Register on January 2, 2003, for Bombardier
model CL-600-2C10 airplanes. That AD limits P/N WE3800770-2 APUs that
have the old design fuel nozzles to ground operation only, until the
new fuel nozzles are installed.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. One commenter approves of the proposal
as-written. No comments were received on the the FAA's determination of
the cost to the public. The FAA has determined that air safety and the
public interest require the adoption of the rule as proposed.
Regulatory Analysis
This final rule does not have federalism implications, as defined
in Executive Order 13132, because it would 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. Accordingly,
the FAA has not consulted with state authorities prior to publication
of this final rule.
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 the 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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
by contacting the Rules Docket at the location provided under the
caption ADDRESSES.

Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends 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.
Sec. 39.13 [Amended]
0
2. Section 39.13 is amended by adding a new airworthiness directive to
read as follows:
2003-15-07 Honeywell International Inc. (formerly AlliedSignal):
Amendment 39-13250. Docket No. 2002-NE-42-AD.
Applicability
This airworthiness directive (AD) is applicable to Honeywell
International Inc. (formerly AlliedSignal) model RE220 (RJ)
auxiliary power units (APUs) part number (P/N) WE3800770-2. These
APUs are installed on, but not limited to Bombardier model CL-600-
2C10 airplanes.
Note 1: This AD applies to each APU 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 APUs 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 (e) 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
Compliance with this AD is required as indicated, unless already
done.
To prevent APU compartment fires and fuel vapor explosion, do
the following:
[[Page 44610]]
(a) Within six months after the effective date of this AD,
replace APU fuel nozzles, P/N WE3830486-2, with new design fuel
nozzles, P/N WE3830513-1. Information on fuel nozzle replacement can
be found in Honeywell International Inc. alert service bulletin
(ASB) RE220-49-A7714, dated November 4, 2002.
(b) Reidentify the APU as follows:
(1) Change the P/N from WE3800770-2 to WE3800770-3 on the
identification plate, by removing the -2 and vibropeening or hand
stamping a -3 in its place.
(2) Vibropeen or hand stamp the letter ``C'' after the serial
number to show conversion.
(3) Vibropeen or hand stamp ``Change Number 3'' on the
identification plate adjacent to the MOD RECORD.
(c) Start the APU and perform a visual fuel leak check after one
minute of operation.
(d) After the effective date of this AD, do not install fuel
nozzles P/N WE3830486-2 into any APU P/N WE3800770-3.
Alternative Methods of Compliance
(e) 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 (LAACO). Operators must submit their requests through an
appropriate FAA Principal Maintenance Inspector, who may add
comments and then send it to the Manager, LAACO.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this airworthiness directive,
if any, may be obtained from the LAACO.
Special Flight Permits
(f) Special flight permits may be issued in accordance with
Sec. Sec. 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be done.
Effective Date
(g) This amendment becomes effective on September 3, 2003.
Issued in Burlington, Massachusetts, on July 24, 2003.
