DEPARTMENT OF TRANSPORTATION Alternative Methods of Compliance (AMOCs) 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 https://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 (800) 647–5227) is located on the plaza 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 VerDate Aug<31>2005 14:27 Sep 20, 2005 Jkt 205001 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 PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 55243 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; 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).

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.
