Federal Aviation Administration August 31, 2018 – Federal Register Recent Federal Regulation Documents

These special conditions are issued for Ultramagic S.A. Models M-56, M-56C, M-65, M-65C, M-77, M-77C, M-90, M-105, M-120, M-130, M- 145, M-160, N-180, N-210, N-250, N-300, N-355, N-425, S-70, S-90, S- 105, S-130, S-160, T-150, T-180, T-210, V-56, V-65, V-77, V-90, and V- 105 balloons. These balloons will have novel or unusual design features associated with a standard construction basket with a singular distribution that includes four occupant seats and a lower sidewall. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The revision of this collection involves the logging of training time in aviation training devices under the provisions of regulations specified in the background of this document, and the logging of flight time as a second in command (SIC) under the provisions of regulations specified in the background of this document.

We propose to supersede Airworthiness Directive (AD) 2016-07- 23, which applies to all Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2016-07-23 requires, for certain airplanes, repetitive replacements of the fixed fairing upper and lower attachment studs of both the left-hand (LH) and right-hand (RH) main landing gear (MLG); and repetitive inspections for corrosion, wear, fatigue cracking, and loose studs of each forward stud assembly of the fixed fairing door upper and lower forward attachments of both the LH and RH MLG; and replacement if necessary. AD 2016-07-23 also provides an optional terminating modification for the repetitive replacements of the fixed fairing upper and lower attachment studs. Since we issued AD 2016-07-23, we have determined that for some airplane configurations, associated fixed fairing assembly part numbers susceptible to fatigue cracking were not listed in certain service information required by AD 2016-07-23. In addition, we have determined that additional work is necessary to re-identify the fixed fairing assembly part number on certain airplanes. This proposed AD would retain the requirements of AD 2016-07-23 and, for certain airplanes, require re-identification of the LH and RH fixed fairing assemblies' part numbers. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-200 Freighter series airplanes, Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. This proposed AD was prompted by defects found during production tests of ram air turbine (RAT) units; investigation revealed that the defects were due to certain RAT hydraulic pumps having an alternative manufacturing process of the pump pistons. This proposed AD would require replacing any defective RAT hydraulic pump with a serviceable part and re-identifying the RAT module part number. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. This AD was prompted by a determination that more restrictive maintenance instructions and airworthiness limitations are necessary. This AD requires updating the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
