Agency Information Collection Activities: Request for Comments: Revision of a Currently Approved Collection; State Right-of-Way Operations Manuals, OMB Control Number 2125-0586.
The FHWA invites public comments about our intention to request the Office of Management and Budget's (OMB) approval for a revision of a currently approved collection, which is summarized below under SUPPLEMENTARY INFORMATION. We are required to publish this notice in the Federal Register by the Paperwork Reduction Act of 1995.
Parts and Accessories Necessary for Safe Operation; Application for an Exemption From Atwood Forest Products, Inc.
FMCSA requests public comment on an application for exemption from Atwood Forest Products, Inc. (Atwood) to allow the use of a camera system installed at the sides and rear of up to 15 of its commercial motor vehicles (CMV) in lieu of rear-vision mirrors as specified in the Federal Motor Carrier Safety Regulations (FMCSR). Section 393.80 of the FMCSRs currently requires every bus, truck, and truck tractor to be equipped with two rear-vision mirrors, one at each side, firmly attached to the outside of the motor vehicle, and so located as to reflect to the driver a view of the highway to the rear along both sides of the vehicle. All such mirrors must, at a minimum, meet the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 111 in effect at the time the vehicle was manufactured. The exemption would enable Atwood to install the camera system on its vehicles for use in an evaluation study, in a location that will offer the best opportunity to optimize data to evaluate the safety and economic benefits of eliminating outside mirrors.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD requires repetitive on-ground power cycles (resets) of the Transponder, Terrain and Traffic Collision Avoidance System (T3CAS). This AD was prompted by reports of spurious terrain ahead warning system (TAWS) alerts during approach and takeoff. We are issuing this AD to prevent spurious TAWS alerts, which could increase flightcrew workload during critical landing or takeoff phases, and result in reduced control of the airplane.
Airworthiness Directives; Technify Motors GmbH Reciprocating Engines
We are adopting a new airworthiness directive (AD) for certain Technify Motors GmbH (type certificate previously held by Thielert Aircraft Engines GmbH) TAE 125-02-99 and TAE 125-02-114 reciprocating engines. This AD requires removal of each high-pressure (HP) fuel pump before 300 flight hours (FHs) in service or within 55 FHs after the effective date of the AD, whichever occurs later. This AD was prompted by in-flight shutdowns on airplanes with TAE 125-02 engines. We are issuing this AD to prevent failure of the HP fuel pump, which could result in damage to the engine and damage to the airplane.
Airworthiness Directives; Dassault Aviation Airplanes
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by reports that the pintle pins installed on a certain number of airplanes may be incorrectly protected against corrosion. This AD requires replacing certain pintle pins on the left- and right-hand main landing gear (MLG) with a serviceable part. We are issuing this AD to detect and correct pintle pins that have been incorrectly corrosion-protected, which could cause the pintle pins to shear under normal load and lead to the collapse of the MLG during take-off or landing.
Airworthiness Directives; BAE Systems (Operations) Limited Airplanes
We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This AD was prompted by reports of cracking of the main fitting of the nose landing gear (NLG). This AD requires revising the maintenance program by incorporating a new safe- life limitation for the NLG main fitting. We are issuing this AD to prevent collapse of the NLG, which could lead to degradation of direction control on the ground or an un-commanded turn to the left, and a consequent loss of control of the airplane on the ground, possibly resulting in damage to the airplane and injury to occupants.
Airworthiness Directives; Embraer S.A. Airplanes
We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by reports of ``BLEED 1(2) LEAK'' messages displayed on the engine indication and crew alert system (EICAS), and indirect damage to components of the electrical wiring interconnection system (EWIS) in the engine pylon area. This AD requires inspecting the EWIS components for damage, and repair if necessary. This AD also requires installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. We are issuing this AD to prevent indirect damage to EWIS components near the engine bleed air pre-coolers, which could result in a dual engine roll back to idle and consequent dual engine power loss and reduced controllability of the airplane.
