Federal Aviation Administration March 20, 2020 – Federal Register Recent Federal Regulation Documents

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

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 information collection is required to receive the benefit of obtaining an FAA Air Agency Certificate, known as a certificated repair station. The collection involves the applicant entering information onto and submitting the FAA Form 8310-3. Application for Repair Station Certificate/and or Rating to the appropriate FAA field office. Persons requesting to obtain an initial Air Agency Certificate to operate as an FAA certificated repair station or request changes to an existing repair station (air agency) certificate do so by submitting the request through the submission of the FAA Form 8310-3. This form is available to the applicant/respondent via www.faa.gov, email, in person, or by mail. The FAA Form 8310-3, Application for Repair Station Certificate and/or Ratings captures information such as, but not limited to; official name of repair station, location where business is conducted, official mailing address, any doing business as name, changes in ratings, or if initial certification, ratings sought, changes in location or housing and facilities, change in name or ownership, or any other purpose for which the applicant requests, including a request for approval to contract maintenance functions to outside entities. The FAA has identified an inaccuracy in how burden calculations are determined associated with initial repair station certifications and subsequent changes to an existing repair station certificate. The FAA has identified that the information collected through the FAA Form 8310-3 does not capture the entire repair station certification activities or changes to an existing certificate. OMB Control Number 2120-0682 is not only authorizing the Agency to receive information collected on the FAA Form 8310-3, but should also encapsulate the entire calculation burden associated with repair station certification and subsequent changes to an existing certificate. Once burden calculations associated with repair station certification activities are properly assessed, the FAA will publish a new notice to the Federal Register capturing the entire burden calculation for repair station certification and subsequent changes to an existing certificate.

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD requires inspecting the attachment screws of each main gearbox (MGB) suspension bar rear attachment fitting, and depending on the outcome, applying a sealing compound, performing further inspections, and replacing affected parts. This AD was prompted by reports of an elongated attachment screw and loss of tightening torque of the nut. The actions of this AD are intended to address an unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A319-131, -132, and -133 airplanes, Model A320-231, - 232, and -233 airplanes, and Model A321-131, -231, and -232 airplanes. This AD was prompted by a report of rupture of a hydraulic reservoir air pressurization hose on an in-service airplane, leading to air leakage that was undetectable during normal operation, and found during subsequent zonal inspection. This AD requires modifying the airplane by replacing the affected bleed air hoses with a modification of hydraulic pressurization lines, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A319-112, -115, and -132 airplanes; and Model A320-214, -216, -232, and -233 airplanes. This AD was prompted by a report that a possible interference was identified between 1M and 2M wiring harnesses and the tapping units, and that the interference could adversely affect the lavatory smoke detection system and/or the passenger oxygen system. This AD requires modifying the 1M and 2M harness routing, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all International Aero Engines, LLC (IAE) PW1122G-JM, PW1124G1-JM, PW1124G- JM, PW1127GA-JM, PW1127G1-JM, PW1127G-JM, PW1133G-JM, PW1133GA-JM, PW1130G-JM, and PW1129G-JM model turbofan engines with a certain low- pressure turbine (LPT) 3rd-stage blade installed. This AD requires initial and repetitive borescope inspections (BSI) of the turbine stator intermediate outer rear air seal (turbine piston seal) and, depending on the results of the inspection, replacement with a part eligible for installation. This AD was prompted by reports of failure of turbine piston seals leading to fracture of the LPT 3rd-stage blades. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. (Type Certificate Previously Held by Embraer S.A.) Model ERJ 170 airplanes. This AD was prompted by a report of erroneous indications of certain engine parameters and reports of ``pitch up'' and ``pitch down'' uncommanded attitudes with autopilot engaged in cruise flight. This AD requires installing updated PRIMUS EPIC LOAD software, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) Brazilian AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, and AS332L2 helicopters. This AD requires removing the drain plugs from the fuel tank compartments located under the bottom structure. This AD was prompted by the discovery that a modification to the fuel tank could lead to fuel accumulating in an area containing electrical equipment and subsequent ignition of fuel vapors. The actions of this AD are intended to address an unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This proposed AD was prompted by reports of fatigue cracks on continuity fittings at the lower framing of the front windshield on airplanes on which a certain production modification has been embodied. Additional analysis showed that certain certification requirements for damage tolerance and fatigue are not met on airplanes in a certain post-production modification configuration. This proposed AD would require repetitive high frequency eddy current (HFEC) inspections of the central node windshield area for cracking, and applicable corrective actions if cracking is found, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all Austro Engine GmbH model E4 and E4P diesel piston engines. This proposed AD was prompted by reports of considerable wear of the timing chain and failure of fuel injectors on these engines. This proposed AD would require replacement of the timing chain and fuel injectors on the affected Austro Engine GmbH model E4 and E4P diesel piston engines. The FAA is proposing this AD to address the unsafe condition on these products.
