PROPOSED RULES
Airworthiness Directives; Hamilton Sundstrand Corporation Propellers [FR
DOC# 2013-17479] SUMMARY: The FAA is withdrawing a notice of proposed
rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) that
had applied to certain Hamilton Sundstrand Corporation 14SF-7, 14SF-15, and
14SF-23 series propellers. The NPRM had applied to those propellers using
certain Hamilton Sundstrand Corporation auxiliary pumps and motors
(auxiliary feathering pumps). The proposed action would have required
removal of certain serial numbers (S/Ns) of auxiliary feathering pumps from
service. Since we issued the NPRM, we attended a meeting sponsored by
Hamilton Sundstrand Corporation, which provided additional information
regarding the unsafe condition. The information included results from bond
strength tests that predicts a significantly lower fleet risk than the prior
qualitative analysis. Accordingly, we withdraw the proposed rule.
Airworthiness Directives; the Boeing Company [FR DOC# 2013-17412] SUMMARY:
We propose to supersede an existing airworthiness directive (AD) that
applies to certain The Boeing Company Model 747 series airplanes. The
existing AD currently requires repetitive detailed inspections to detect
cracking in certain fuselage upper deck tension ties, repair or modification
of any cracked tension ties, and repetitive inspections of repaired and
modified tension ties and repair or modification if necessary. The existing
AD also provides for optional terminating action for the repetitive detailed
inspections of tension ties that have not been repaired or modified. This
proposed AD was prompted by an evaluation by the design approval holder
indicating that the upper deck tension ties of the fuselage are subject to
widespread fatigue damage. This proposed AD would retain the repetitive
inspections, mandate the previously optional terminating modification, and
add, for tension ties that have not been repaired or modified, repetitive
inspections that must be done concurrently with the existing repetitive
inspections. We are proposing this AD to prevent widespread fatigue damage
of certain fuselage upper deck tension ties, which could result in reduced
structural integrity of the airplane.
RULES
Airworthiness Directives; Bombardier, Inc. Airplanes [FR DOC# 2013-17210]
SUMMARY: We are superseding airworthiness directive (AD) 2011-13-08 for
certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2011-13- 08
required a free-play check for excessive free-play of the shaft swaged
bearing installed in the tailstock end of each elevator power control unit
(PCU), and replacing any PCU on which the bearing exceeds allowable limits
with a serviceable PCU. This new AD adds airplanes to the applicability from
that of AD 2011-13-08. This AD was prompted by a determination that
additional airplanes are affected by the identified unsafe condition. We are
issuing this AD to detect and correct excessive free-play of the swaged
bearings, which could lead to excessive airframe vibrations and difficulties
in pitch control, and consequent loss of controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-17137]
SUMMARY: We are adopting a new airworthiness directive (AD) for certain The
Boeing Company Model 747-400 and 747-400F series airplanes. This AD was
prompted by reports of cracking in the outboard flange of the longeron
extension fittings, which attach to the wing-to-body fairing support frame.
This AD requires repetitive inspections of the longeron extension fittings
for cracking, and corrective actions if necessary. We are issuing this AD to
detect and correct cracks in the longeron extension fittings, which can
become large and adversely affect the structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-16927]
SUMMARY: We are adopting a new airworthiness directive (AD) for all The
Boeing Company Model 727 airplanes. This AD was prompted by reports of
spanwise cracks and corrosion in the wing center box upper skin and rear
spar upper chord between left buttock line (LBL) 70.50 and right buttock
line (RBL) 70.50 at body station (STA) 870. This AD requires repetitive
inspections of the wing center box for cracking around certain fastener rows
on the rear spar upper chord horizontal flange; for certain airplanes,
repetitive inspections for cracking of the rear spar upper chord radius; for
certain other airplanes, repetitive inspections for damage, cracking, and
corrosion of the pressure seal; and repair if necessary. We are issuing this
AD to detect and correct cracking and corrosion of the upper skin and rear
spar upper chord of the wing center box, which could result in loss of the
airplane wing and consequent loss of control of the airplane.
Airworthiness Directives; Learjet Inc. Airplanes [FR DOC# 2013-16929]
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Learjet Inc. Model 45 airplanes. This AD was prompted by a report that the
fire barrier seal on the external baggage door does not seal the surrounding
door structure due to incorrect positioning of the barrier. This AD requires
modifying the fire seal on the baggage door, including doing inspections of
the fire seal for correct contact and corrective action if necessary. We are
issuing this AD to prevent improper sealing of the baggage door, which could
increase the risk of an uncontained fire in the baggage compartment.
Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-16930]
SUMMARY: We are adopting a new airworthiness directive (AD) for all The
Boeing Company Model 727 airplanes. This AD was prompted by reports of
cracks on the elevator rear spar stiffener assembly. This AD requires
repetitive detailed inspections for cracking of the elevator rear spar
stiffener assembly, and corrective actions if necessary. We are issuing this
AD to detect and correct cracking of the elevator rear spar stiffener
assembly, which could adversely affect elevator structural stiffness, which
could lead to elevator vibration and possible interference with the tab
control rod. These conditions could result in flutter and consequent loss of
control of the airplane.
Modification of Class B Airspace; Las Vegas, NV [FR DOC# 2013-17477]
SUMMARY: This action modifies the Las Vegas, NV, Class B airspace area to
ensure the containment of large turbine-powered aircraft within Class B
airspace, reduce air traffic controller workload, and reduce the potential
for midair collision in the Las Vegas, NV, terminal area.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle
Departure Procedures; Miscellaneous Amendments [FR DOC# 2013-17411] SUMMARY:
This rule establishes, amends, suspends, or revokes Standard Instrument
Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle
Departure Procedures for operations at certain airports. These regulatory
actions are needed because of the adoption of new or revised criteria, or
because of changes occurring in the National Airspace System, such as the
commissioning of new navigational facilities, adding new obstacles, or
changing air traffic requirements. These changes are designed to provide
safe and efficient use of the navigable airspace and to promote safe flight
operations under instrument flight rules at the affected airports.
