Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2006-20- 11, which applies to certain The Boeing Company Model 757-200, -200CB, and -200PF series airplanes. AD 2006-20-11 currently requires initial and repetitive detailed or high frequency eddy current (HFEC) inspections for cracks around the rivets at the upper fastener row of the skin lap splice of the fuselage, and repairing any crack found. Since we issued AD 2006-20-11, an evaluation done by the design approval holder (DAH) indicated that the fuselage skin lap splice is subject to widespread fatigue damage (WFD). This proposed AD would no longer allow the detailed inspections and would instead require repetitive external HFEC inspections for cracking of the skin lap splices of the fuselage, and repair if necessary. We are proposing this AD to detect and correct fatigue cracking at certain skin lap splice locations of the fuselage, which could result in reduced structural integrity and rapid decompression of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-19- 04, which applies to certain The Boeing Company Model 737-600, -700, - 700C, -800, and -900 series airplanes. AD 2013-19-04 currently requires repetitive detailed and high frequency eddy current (HFEC) inspections for cracking of the skin around the eight fasteners common to the ends of the station (STA) 540 bulkhead chords between stringers S-22 and S- 23, left and right sides; related investigative actions and corrective actions, if necessary; and provides an optional terminating modification. Since we issued AD 2013-19-04, we have received reports of additional cracks that are larger and initiated sooner than previously predicted. This proposed AD would reduce the inspection threshold and repetitive inspection intervals. We are proposing this AD to detect and correct fatigue cracking in the fuselage skin around the eight fasteners securing the STA 540 bulkhead chords. Such cracking can result in rapid decompression of the cabin.
Aviation Rulemaking Advisory Committee-New Task
The FAA has assigned the Aviation Rulemaking Advisory Committee (ARAC) a new task to provide recommendations regarding the certification of persons engaged in operations involving the loading of special cargo. Assignment of this task is in response to National Transportation Safety Board Recommendation A-15-014 which recommended that the FAA create a certification for personnel responsible for the loading, restraint, and documentation of special cargo loads on transport-category airplanes. This notice informs the public of the new ARAC activity and solicits membership for the new Loadmaster Certification Working Group.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain ATRGIE Avions de Transport R[eacute]gional Model ATR42-500 and Model ATR72-212A airplanes. The NPRM proposed to require measuring the gap between the Type III Emergency Exit doors and certain overhead stowage compartment fittings; removing certain fittings from the overhead stowage compartments and measuring the gap between the Type III Emergency Exit doors and the overhead stowage compartment hooks, if necessary; and re-installing or repairing, as applicable, the Type III Emergency Exit doors. The NPRM was prompted by a report indicating that interference occurred between a Type III Emergency Exit door and the surrounding passenger cabin furnishing during a production check. This action revises the NPRM by adding new proposed requirements for modifying the overhead stowage compartments. We are proposing this supplemental NPRM (SNPRM) to prevent interference between a Type III Emergency Exit door and the overhead stowage compartment fitting installed on the rail; which could result in obstructed opening of a Type III Emergency Exit door during an emergency evacuation. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Regulatory Relief: Aviation Training Devices; Pilot Certification, Training, and Pilot Schools; and Other Provisions
This rulemaking would relieve burdens on pilots seeking to obtain aeronautical experience, training, and certification by increasing the allowed use of aviation training devices. These training devices have proven to be an effective, safe, and affordable means of obtaining pilot experience. This rulemaking also would address changing technologies by accommodating the use of technically advanced airplanes as an alternative to the use of older complex single engine airplanes for the commercial pilot training and testing requirements. Additionally, this rulemaking would broaden the opportunities for military instructors to obtain civilian ratings based on military experience, would expand opportunities for logging pilot time, and would remove a burden from sport pilot instructors by permitting them to serve as safety pilots. Finally, this rulemaking would include changes to some of the provisions established in an August 2009 final rule. These actions are necessary to bring the regulations in line with current needs and activities of the general aviation training community and pilots.
