Airplanes; Equipped With Certain
Cockpit Door Installations
AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Bombardier Model DHC–8–102, –103,
–106, –201, –202, –301, –311, –314, and
–315 airplanes. This AD requires certain
Bombardier Model DHC–8–102, –103,
–106, –201, –202, –301, –311, –314, and
–315 airplanes. This AD results from a
report that, during structural testing of
the cockpit door, the lower hinge block
rotated and caused the mating hinge pin
to disengage, and caused excessive door
deflection. We are issuing this AD to
prevent failure of a door attachment,
which could result in uncontrolled
release of the cockpit door under certain
fuselage decompression conditions, and
possible damage to the airplane
structure.
DATES: This AD becomes effective July
18, 2006.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of July 18, 2006.

Examining the Docket
You may examine the airworthiness
directive (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 would
apply to certain Bombardier Model
DHC–8–102, –103, –106, –201, –202,
–301, –311, –314, and –315 airplanes.
That NPRM was published in the
Federal Register on April 11, 2006 (71
FR 18244). That NPRM proposed to
require modifying the hinge attachment
for the cockpit door from a single-point
attachment to a two-point attachment.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the one comment received.
The commenter, the Air Line Pilots
Association, supports the NPRM.
Conclusion
We have carefully reviewed the
available data, including the comment
received, and determined that air safety
and the public interest require adopting
the AD as proposed.
Costs of Compliance
This AD will affect about 16 airplanes
of U.S. registry. The required actions
will take between 3 and 6 work hours
per airplane, depending on the airplane
configuration. The average labor rate is
$80 per work hour. Required parts will
cost about $2,000 per airplane. Based on
these figures, the estimated cost of this
AD for U.S. operators is between
$35,840 and $39,680, or between $2,240
and $2,480 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
E:\FR\FM\13JNR1.SGM
13JNR1
Federal Register / Vol. 71, No. 113 / Tuesday, June 13, 2006 / Rules and Regulations
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.

Administration Regulations. The
procedures of part 756 apply to actions
other than the issuance, amendment,
revocation or appeal of a regulation, and
most enforcement actions taken under
part 764 or 766 of the EAR. Part 756
authorizes the Under Secretary for
Industry and Security to designate an
‘‘appeals coordinator to assist in the
review and processing of an appeal

part 756 authorized the Under Secretary
for Industry and Security to designate
‘‘any BIS official’’ as appeals
coordinator. This rule authorizes the
Under Secretary for Industry and
Security to designate any employee of
the Department of Commerce to be the
appeals coordinator. The Under
Secretary for Industry and Security must
have the concurrence of the head of the
operating unit in which the employee is
employed to make such a designation of
a Department of Commerce employee
who is not an employee of BIS.
The agency is making this change,
which is administrative in nature, in
order to provide the Under Secretary
and the Department of Commerce with
additional flexibility in allocating
limited legal and official staff resources
to the review and processing of appeals
under part 756. The authority to decide
appeals will remain with the Under
Secretary, in accordance with section
756.2(c)(1) of the EAR, subject to the
Under Secretary’s authority to delegate
that function to the Deputy Under
Secretary or another BIS official in
accordance with section 756.2(a).
Moreover, this change will not affect the
Under Secretary’s authority to consider
recommendations or other relevant
information (from either the appeals
coordinator or any other source) in
deciding appeals, in accordance with
section 756.2(c)(1). Nor will this change
affect the substance of the agency’s
ongoing decision-making activities.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311,
-314, and -315 airplanes. This AD requires certain Bombardier Model
DHC-8-102, -103, -106, -201, -202, -301, -311, -314, and -315
airplanes. This AD results from a report that, during structural
testing of the cockpit door, the lower hinge block rotated and caused
the mating hinge pin to disengage, and caused excessive door
deflection. We are issuing this AD to prevent failure of a door
attachment, which could result in uncontrolled release of the cockpit
door under certain fuselage decompression conditions, and possible
damage to the airplane structure.
DATES: This AD becomes effective July 18, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 18, 2006.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Bombardier
Model DHC-8-102, -103, -106, -201, -202, -301, -311, -314, and -315
airplanes. That NPRM was published in the Federal Register on April 11,
2006 (71 FR 18244). That NPRM proposed to require modifying the hinge
attachment for the cockpit door from a single-point attachment to a
two-point attachment.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the one comment received.
The commenter, the Air Line Pilots Association, supports the NPRM.
Conclusion
We have carefully reviewed the available data, including the
comment received, and determined that air safety and the public
interest require adopting the AD as proposed.
Costs of Compliance
This AD will affect about 16 airplanes of U.S. registry. The
required actions will take between 3 and 6 work hours per airplane,
depending on the airplane configuration. The average labor rate is $80
per work hour. Required parts will cost about $2,000 per airplane.
Based on these figures, the estimated cost of this AD for U.S.
operators is between $35,840 and $39,680, or between $2,240 and $2,480
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
[[Page 34007]]
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.

Unsafe Condition
(d) This AD results from a report that, during structural
testing of the cockpit door, the lower hinge block rotated and
caused the mating hinge pin to disengage, and caused excessive door
deflection. We are issuing this AD to prevent failure of a door
attachment, which could result in uncontrolled release of the
cockpit door under certain fuselage decompression conditions, and
possible damage to the aircraft structure.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Modification
(f) Within 24 months after the effective date of this AD, modify
the cockpit door from a single-point attachment to a two-point
attachment in accordance with the Accomplishment Instructions of the
applicable service bulletin in Table 2 of this AD.
