Agency responsibilities.
(a) To assist in the assessment of the
management of human capital in the
Federal Government, and to help meet
the statutory requirements to prepare
that portion of the performance budget
for which agency Chief Human Capital
Officers are accountable as well as
relevant portions of performance and
accountability reports, heads of agencies
or their designees must maintain a
current human capital plan and provide
OPM an annual human capital
accountability report, as outlined below,
based on an approved human capital
accountability system. The HCAAF and
the HCAAF–SSM provide more specific
information on coverage and content for
the plan and report.
(1) Human Capital Plan. Using a
format established by agreement
between the agency and OPM, at a
minimum the plan must include:
(i) Human Capital Goals and
Objectives. These are a comprehensive,
integrated set of human capital goals
and objectives, with detailed policy and
program priorities and initiatives as
appropriate, consistent with agency
strategic plans and annual performance
goals. These human capital goals and
objectives must address each of the
human capital management systems
included in the HCAAF.
(ii) Workforce Analysis. This analysis
of the agency’s workforce describes its
current state, projects the human
resources needed to achieve the
agency’s program performance goals and
objectives during the term of the
agency’s strategic plan, and identifies
potential shortfalls or gaps. An ongoing
analysis must, for relevant agency

mission requirements, describe the
occupation(s) most critical to agency
performance (including associated
managerial and executive positions) and
describe mission-critical competencies
and key demographics (e.g., talent
analyses, turnover, and retirement
eligibility); and for each such
occupation, describe its current and
projected staffing levels, attrition and
hiring estimates, and proposed training
and development investments.
(iii) Performance Measures and
Milestones. One or more human capital
metrics, as well as appropriate program
milestones, for each human capital goal
or objective, provide a basis for
assessing progress and results, including
compliance measures with respect to
relevant laws, rules and regulations.
These metrics must include, but are not
limited to, those described in the
HCAAF–SSM issued under § 250.202(b).
These metrics and milestones must be
specifically linked to broader agency
program performance measures, to
evaluate the impact of the agency’s
human capital management on its
overall mission performance.
(2) Human Capital Accountability
System and Report. This system
provides for an annual assessment of
agency human capital management
progress and results including
compliance with relevant laws, rules,
and regulations. That assessment is
conveyed in an annual human capital
accountability report to OPM. The
human capital accountability system
must be formal and documented; be
approved by OPM; be supported and
resourced by agency leadership;
measure and assess human capital
management systems for mission
alignment, effectiveness, efficiency, and
compliance with merit system
principles, laws, and regulations;
include an independent audit process
with periodic review of human
resources transactions to insure legal
and regulatory compliance; ensure that
action is taken to improve human
capital management programs and
processes and to correct deficiencies;
and ensure results are analyzed and
reported to agency management and
OPM. At a minimum, the agency’s
annual human capital accountability
report must:
(i) Provide an evaluation of and report
on the agency’s existing human capital
management policies, programs, and
operations, as they relate to the agency’s
overall mission/program performance.
The report must address the
performance measures and milestones
contained in the agency human capital
plan including compliance measures
with respect to relevant laws, rules and
PO 00000
Frm 00003
Fmt 4702

29595
regulations. The report must also
document actions taken to correct any
violations or deficiencies that are
identified.
(ii) Inform the development of human
capital goals and objectives during the
agency’s strategic planning and annual
performance budget formulation
process, as well as the treatment of
human capital results during the annual
performance and accountability
reporting process.
(b) The Director of OPM may, at his
or her discretion, grant a variation from
any requirement of this section under 5
CFR 5.1. A request for a variation must
be submitted by the head of the
requesting agency, and must be based
on conditions specific to the requesting
agency. The Director’s decision granting
or denying the variation request has no
precedential effect under 5 CFR 5.1(a).

(NPRM).
AGENCY:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for certain
Raytheon Aircraft Company Model 390
airplanes. This proposed AD would
require you to inspect the spigot
bearing, part number (P/N) MS14104–
16, for the proper position in the spigot
fitting assembly and to install the wing
spigot bearing retainer kit, P/N 390–
4304–0001. This proposed AD results
from two reports of the spigot bearing
not being positioned flush with the
fitting assembly, but protruding outside
of the fitting assembly. We are
proposing this AD to detect spigot
bearings that are not positioned flush
with the fitting assembly. This
condition could result in the spigot
bearing becoming disengaged from the
fitting assembly, which could cause
motion between the wing and the
fuselage and degrade the structural
integrity of the wing attachment to the
fuselage. This could lead to wing

Comments Invited
We invite you to send any written
relevant data, views, or arguments
regarding this proposed AD. Send your
comments to an address listed under the
ADDRESSES section. Include the docket
number, ‘‘FAA–2006–24640; Directorate
Identifier 2006–CE–26–AD’’ at the
beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
the proposed AD. We will consider all

concerning this proposed AD.
Discussion
We have received two reports of the
spigot bearing not being positioned
flush with the fitting assembly, but
protruding outside of the fitting
assembly on Raytheon Aircraft
Company Model 390 airplanes. The
spigot bearing transfers forward, aft, and
side loads between the wing and the
fuselage. If the spigot bearing becomes
disengaged from the fitting assembly,
inflight loads could cause motion
between the wing and the fuselage and
degrade the structural integrity of the
wing attachment to the fuselage.
This condition, if not corrected, could
result in wing separation and loss of
control of the airplane.
Relevant Service Information
We have reviewed Raytheon Aircraft
Company Mandatory Service Bulletin
SB 53–3765, issued: November, 2005.
The service information describes
procedures for:
• Inspecting the spigot bearing for
proper position in the spigot fitting
assembly; and
• Installing the wing spigot bearing
retainer kit P/N 390–4304–0001.
FAA’s Determination and Requirements
of the Proposed AD
We are proposing this AD because we
evaluated all information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This proposed AD would
require you to inspect the spigot
bearing, P/N MS14104–16, for proper
position in the spigot fitting assembly
and to install the wing spigot bearing
retainer kit, P/N 390–4304–0001.
Costs of Compliance
We estimate that this proposed AD
would affect 78 airplanes in the U.S.
registry.
We estimate the following costs to do
the proposed inspection:

Total cost per
airplane
Total cost on
