Airworthiness Directives; Eurocopter France Model AS355E, F, F1, F2, and N Helicopters
This document proposes to revise an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters. That AD currently requires certain checks of the magnetic chip detector plug (chip detector) and the main gearbox (MGB) oil-sight glass, certain inspections of the lubrication pump (pump), and replacing the MGB and the pump with an airworthy MGB and pump, if necessary. Also, the AD requires that before an MGB or pump with any time-in-service (TIS) can be installed, it must meet the AD requirements. This action would retain those requirements but would limit the applicability to one part number with certain serial-numbered pumps or modified after a certain date. This proposal was prompted by an investigation by the manufacturer that revealed a malfunction occurred after modifying the pump case on certain pumps after major overhaul and repairs. The actions specified by this AD are intended to limit the applicability to certain pumps, to detect sludge on the chip detector, to prevent failure of the MGB pump, seizure of the MGB, loss of drive to an engine and main rotor, and subsequent loss of control of the helicopter.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA proposes to supersede two existing airworthiness directives (ADs), one AD applicable to all Boeing Model 747 airplanes and the other AD applicable to certain Boeing Model 747 airplanes. The first AD currently requires repetitive inspections for cracking of the upper skin of the horizontal stabilizer center section and the rear spar upper chord, and repair if necessary. The other AD currently requires repetitive inspections for cracking of the upper skin of the outboard and center sections of the horizontal stabilizer and the rear spar structure, hinge fittings, terminal fittings, and splice plates; and repair if necessary. This proposed AD would add, for certain airplanes, repetitive inspections for cracking of the outboard and center sections of the horizontal stabilizer and repair if necessary. For certain other airplanes, this proposed AD would add a detailed inspection to determine the type of fasteners, related investigative actions, and repair if necessary. This proposed AD also would revise the compliance times for certain inspections and add alternate inspections for cracking of the upper skin of the center section and rear spar upper chord. This proposed AD is prompted by reports of cracking in the outboard and center section of the aft upper skin of the horizontal stabilizer, the rear spar chord, rear spar web, terminal fittings, and splice plates; and a report of fractured and cracked steel fasteners. We are proposing this AD to detect and correct this cracking, which could lead to reduced structural capability of the outboard and center sections of the horizontal stabilizer and could result in loss of control of the airplane.
Airworthiness Directives; Gulfstream Aerospace LP Model Gulfstream 100 Airplanes; and Model Astra SPX, and 1125 Westwind Astra Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream 100 airplanes; and Model Astra SPX, and 1125 Westwind Astra airplanes. This proposed AD would require a one-time inspection for discrepancies of the nose wheel steering assembly of the landing gear, installing a warning placard on each nose landing gear door, and corrective action if necessary. This proposed AD is prompted by reports of failure of the steering brackets of the nose wheel steering assembly, and in one incident, loss of steering control. We are proposing this AD to find and fix these discrepancies, which could result in loss of steering control and consequent reduced controllability of the airplane.
Notice Publishing Substantive Criteria for Evaluation of Applications under the Railroad Rehabilitation and Improvement Financing Program (RRIF)
FRA is publishing this notice in response to Congressional direction contained in section 9003(j) of the recently enacted Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) requesting the agency to identify the substantive criteria and standards used by the DOT/FRA to determine whether to approve or disapprove applications submitted under the RRIF Program. This information is being provided by publication in the Federal Register and posting on the DOT/FRA website, as required by the statute.
