Airspace Designations; Incorporation by Reference Amendments
This action incorporates certain airspace designation amendments into FAA Order 7400.11C, dated August 13, 2018, and effective September 15, 2018, for incorporation by reference.
Airworthiness Directives; BRP-Rotax GmbH & Co KG Engines
We propose to adopt a new airworthiness directive (AD) for certain BRP-Rotax GmbH & Co KG (Rotax) 912 and 914 model engines. This proposed AD was prompted by power loss and engine revolutions per minute (RPM) drop on Rotax 912 and 914 model engines due to a quality control deficiency in the manufacturing process of certain valve push- rod assemblies resulting in partial wear on the rocker arm ball socket and possible malfunction of the valve. This proposed AD would require a one-time inspection and, depending on the findings, replacement of the affected parts with parts eligible for installation. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
We propose to supersede Airworthiness Directive (AD) 2017-07- 05, which applies to all Airbus SAS Model A300 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 2017-07-05 requires repetitive detailed visual inspections of the main landing gear (MLG) leg components and replacement of the MLG leg if cracked components are found. Since we issued AD 2017-07-05, further investigation revealed that overhaul of the MLG does not alleviate the need for inspecting the MLG hinge arm/ barrel pin for cracking. This proposed AD would retain the requirements of AD 2017-07-05 and remove the credit for doing a MLG overhaul in lieu of the initial inspection of the MLG leg components. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
We are revising an earlier proposal, which would have applied to certain Airbus SAS Model A350-941 airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding airplanes to the applicability and proposing to require revised maintenance requirements and airworthiness limitations. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these changes would impose an additional burden over the proposed requirements in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
