Department of Transportation March 11, 2013 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus Airplanes
Document Number: 2013-05563
Type: Proposed Rule
Date: 2013-03-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a determination that certain maintenance activities, such as repairs or the accumulation of paint layers, might cause the weight of an elevator to exceed the certified limits. This proposed AD would require checking the weight of certain elevators, and corrective action if necessary; and re-identifying the elevators. We are proposing this AD to detect and correct elevators that exceed the certified weight limits, which could result in reduced control of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2013-05505
Type: Proposed Rule
Date: 2013-03-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to all The Boeing Company Model 737-300, -400, and - 500 series airplanes. The existing AD currently requires repetitive inspections of the downstop assemblies on the main tracks of the No. 2, 3, 4, and No. 5 slats and the inboard track of the No. 1 and 6 slats to verify if any parts are missing, damaged, or in the wrong order; other specified actions; and related investigative and corrective actions if necessary. Since we issued that AD, the manufacturer has developed a modification, which, when installed, would terminate the repetitive inspections. This proposed AD would add an inspection of the slat can interior for foreign object debris (FOD), and removal of any FOD found; modification of the slat track hardware; an inspection for FOD and for damage to the interior surface of the slat cans; and related investigative and corrective actions, if necessary. We are proposing this AD to prevent loose or missing parts in the main slat track downstop assemblies, which could puncture the slat track housing and result in a fuel leak and consequent fire.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2013-05196
Type: Rule
Date: 2013-03-11
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes. This AD was prompted by reports of cracks of the hinge bearing lugs of the center section ribs of the horizontal stabilizer. This AD requires repetitive high frequency eddy current (HFEC) inspections for cracking of the left and right rib hinge bearing lugs of the aft face of the center section of the horizontal stabilizer; measuring crack length and blending out cracks; and replacing the horizontal stabilizer center section rib, if necessary. We are issuing this AD to detect and correct cracking in the hinge bearing lugs of the horizontal stabilizer center section ribs, which could result in failure of the lugs, and consequent inability of the horizontal stabilizer to sustain the required limit loads and loss of control of the airplane.
Airworthiness Directives; Airbus Airplanes
Document Number: 2013-05193
Type: Rule
Date: 2013-03-11
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by a report that erroneous height indication by one radio altimeter with engaged flare and retard mode, in case of go-around, might lead to a temporary loss of airplane longitudinal control. This AD requires revising the airplane flight manual. We are issuing this AD to ensure that the flightcrew applies the appropriate operational procedures in the event of an erroneous indication of the radio altimeter, which could result in temporary loss of airplane longitudinal control.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2013-04224
Type: Rule
Date: 2013-03-11
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the Eurocopter France (Eurocopter) Model AS332C, AS332L, and AS332L1 helicopters. This AD requires modifying the main landing gear control panel (control panel) 33G, connector 100G, and wiring. It also requires tests to ensure that these modifications function correctly. This AD was prompted by reports of electro-valve power supply disruptions while a helicopter is on the ground, causing the landing gear to retract and the helicopter nose to drop. This results in damage to the forward section of the helicopter's bottom structure. The actions of this AD are intended to prevent an uncommanded landing gear retraction that would cause the helicopter nose to drop and hit the ground while the rotor blades are spinning.
Hazardous Materials; Miscellaneous Amendments (RRR)
Document Number: 2013-04198
Type: Rule
Date: 2013-03-11
Agency: Pipeline and Hazardous Materials Safety Administration, Department of Transportation
PHMSA is amending the Hazardous Materials Regulations (HMR) to make miscellaneous amendments to update and clarify certain regulatory requirements. These amendments promote safer transportation practices, eliminate unnecessary regulatory requirements, address a petition for rulemaking, incorporate a special permit into the HMR, facilitate international commerce, and simplify the regulations. These amendments also update various entries in the Hazardous Materials Table (HMT) and corresponding special provisions, clarify the lab pack requirements for temperature-controlled materials, and require hazmat employers to make hazmat employee training records available upon request to an authorized official of the Department of Transportation (DOT) or an entity explicitly granted authority to enforce the HMR.
