Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD)
for all Model 382, 382B, 382E, 382F, and 382G airplanes. That AD
currently requires revising the FAA-approved maintenance program by
incorporating new airworthiness limitations for fuel tank systems to
satisfy Special Federal Aviation Regulation No. 88 requirements. That
AD also requires the accomplishment of certain fuel system
modifications, the initial inspections of certain repetitive fuel
system limitations to phase in those inspections, and repair if
necessary. This new AD corrects certain part number references, adds an
additional inspection area, and for certain airplanes, requires certain
actions to be re-accomplished according to revised service information.
This AD was prompted by a report of incorrect accomplishment
information in the service information cited by the existing AD. We are
issuing this AD to prevent the potential for ignition sources inside
fuel tanks caused by latent failures, alterations, repairs, or
maintenance actions, which, in combination with flammable fuel vapors,
could result in a fuel tank explosion and consequent loss of the
airplane.
DATES: This AD is effective August 19, 2011.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of August 19,
2011.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of
November 3, 2008 (73 FR 56464, dated September 29, 2008).

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede airworthiness directive (AD) 2008-20-01, amendment
39-15680 (73 FR 56464, September 29, 2008). That AD applies to the
specified products. The NPRM published in the Federal Register on
January 5, 2011 (76 FR 485). That NPRM proposed to continue to require
revising the maintenance program by incorporating new airworthiness
limitations for fuel tank systems to satisfy Special Federal Aviation
Regulation No. 88 requirements. That NPRM also proposed to continue to
require the accomplishment of certain fuel system modifications, the
initial inspections of certain repetitive fuel system limitations to
phase in those inspections, and repair if necessary. That NPRM also
proposed to correct certain part number references, add an additional
inspection area, and for certain airplanes, require certain actions to
be re-accomplished according to revised service information.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the proposal
and the FAA's response to the comment.
Request To Revise Cost Estimate
Lynden Air Cargo requested that the cost for revising the
Instructions for Continued Airworthiness be included in the Costs of
Compliance estimate. Lynden Air Cargo stated that there is a
significant amount of work-hours associated with revising ``company
manuals, job cards, maintenance programs, computerized tracking
programs and record keeping documents'' so that the operator can comply
with the requirements of a new AD. Lynden Air Cargo estimated that
these actions will take at least 80 work-hours for its office staff,
and estimated that this cost would affect other operators. Lynden Air
Cargo also pointed out that this work load for the office staff will
have a greater impact on smaller fleet operators with smaller staff.
We agree that a requirement of the new AD will require an update of
the maintenance program to incorporate references to revised service
information. This action is estimated to take approximately 1 work-hour
per airplane. However, we disagree with increasing the estimated work-
hours for the time that it takes for writing job cards, tracking
programs, or record-keeping, since those actions are not directly
required by this AD. The costs specified by Lynden Air Cargo will not
be the same for all operators. The Costs of Compliance estimate has
been revised accordingly.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD as proposed.
Costs of Compliance
There are about 62 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this AD. The average labor rate per hour
is $85. The costs of the new requirements of this AD are as follows:

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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.

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 according
to paragraph (o) 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.
