PROPOSED RULES

Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-15694]
SUMMARY: We propose to supersede three existing airworthiness directives
(ADs) that apply to The Boeing Company Model 757-200, – 200PF, and -200CB
series airplanes. The existing ADs currently require repetitive inspections
and audible tap tests of the upper and lower skins of the trailing edge
wedges on certain slats, and related investigative and corrective actions if
necessary. Since we issued these ADs, we have received reports of slats
disbonding on airplanes on which the terminating actions of the existing ADs
were completed and also reports of slats disbonding on airplanes outside of
the applicability of the existing ADs. This proposed AD would require a
determination of the type of trailing edge wedges of the leading edge slats,
repetitive inspections on certain trailing edge wedges for areas of skin-
to-core disbonding, and corrective actions if necessary. This proposed AD
would also provide an optional terminating action for the repetitive
inspections. This AD would revise the applicability of the existing ADs to
include additional airplanes. We are proposing this AD to prevent
delamination of the trailing edge wedge of the leading edge slats, possible
loss of pieces of the trailing edge wedge assembly during flight, reduction
of the reduced maneuver and stall margins, and consequent reduced
controllability of the airplane.

 

RULES

Adoption of Statutory Prohibition on the Operation of Jets Weighing 75,000
Pounds or Less That Are Not Stage 3 Noise Compliant [FR DOC# 2013-15843]
SUMMARY: This rulemaking amends the airplane operating regulations to
include certain provisions of the FAA Modernization and Reform Act of 2012
that affect jet airplanes with a maximum weight of 75,000 pounds or less
operating in the United States. The law provides that after December 31,
2015, such airplanes will not be allowed to operate in the contiguous United
States unless they meet Stage 3 noise levels. This final rule incorporates
that prohibition and describes the circumstances under which an otherwise
prohibited airplane may be operated.

Airworthiness Directives; Embraer S.A. Airplanes [FR DOC# 2013-15637]
SUMMARY: We are superseding airworthiness directive (AD) 2010-14-14 that
applies to certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. AD
2010-14-14 currently requires, for certain airplanes, repetitively replacing
the low-stage check valve and associated seals of the right hand (RH)
engine’s engine bleed system with a new check valve and new seals, replacing
the low pressure check valves (LPCVs), and revising the maintenance program.
For certain other airplanes, AD 2010-14-14 requires replacing a certain
low-stage check valve with an improved low-stage check valve. For certain
airplanes, this new AD adds replacing certain LPCVs of the left hand (LH)
and RH engines, which would be an option for other airplanes. This AD was
prompted by reports of uncommanded engine shutdowns on both Model ERJ 170
and ERJ 190 airplanes due to excessive wear and failure of LPCVs having
certain part numbers. We are issuing this AD to prevent the possibility of a
dual engine in-flight shutdown due to LPCV failure.

Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-15692]
SUMMARY: We are adopting a new airworthiness directive (AD) for certain The
Boeing Company Model 747-400, -400D, and -400F series airplanes. This AD was
prompted by reports of two in-service occurrences on Model 737-400 airplanes
of total loss of boost pump pressure of the fuel feed system, followed by
loss of fuel system suction feed capability on one engine, and in-flight
shutdown of the engine. This AD requires repetitive operational tests of the
engine fuel suction feed of the fuel system, and other related testing and
corrective actions if necessary. We are issuing this AD to detect and
correct loss of the engine fuel suction feed capability of the fuel system,
which, in the event of total loss of the fuel boost pumps, could result in
multi- engine flameout, inability to restart the engines, and consequent
forced landing of the airplane.

Airworthiness Directives; Learjet Inc. Airplanes [FR DOC# 2013-15402]
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Learjet Inc. Model 60 airplanes. This AD was prompted by a report of a
high-speed rejected takeoff caused by all four main landing gear (MLG) tires
blowing out during the takeoff roll. This AD requires installing new rigid
hydraulic tube assemblies to the MLG struts; installing a new MLG squat
switch bracket, modifying the MLG squat switch wire harness; modifying the
MLG anti-skid wheel transducer electrical wire harnesses; routing and
securing the anti-skid wheel and squat switch electrical wire harnesses to
the MLG strut assembly; installing outboard bracket assemblies, anti-skid
shield, forward electrical cover on the forward stiffener, upper and lower
inboard bracket assemblies, and clamps that support the electrical wire
harness; modifying the aft stiffener for the new electrical wire harness
support; installing the aft electrical cover and strap on the aft stiffener;
installing a new flat landing light lamp if necessary; and, for certain
airplanes, installing a new wheel speed detect box assembly, nutplates, and
brackets and a new thrust reverser interface box, and modifying the wiring
for the new thrust reverser interface box. We are issuing this AD to prevent
failure of the braking system or adverse operation of the spoiler and thrust
reverser system due to external damage, particularly from tire failure,
which could result in loss of control of the airplane.
