Airworthiness Directives; Honeywell International Inc. Turboprop Engines
We propose to supersede Airworthiness Directive (AD) 88-12-10, which applies to certain Honeywell International Inc. (Honeywell) TPE331 turboprop engines. AD 88-12-10 requires reducing the life limit for certain second stage turbine rotors. Since we issued AD 88-12-10, we received a report that a TPE331-11U engine experienced an uncontained rotor separation. In addition, cracks were discovered through eddy current inspection (ECI) in the bore of the second stage turbine rotor assembly after publication of AD 88-12-10. This proposed AD would require removing certain second stage turbine rotors from service at a reduced life limit. We are proposing this AD to address the unsafe condition on these products.
Petition for Exemption; Summary of Petition Received; Cruiser Aircraft, Inc.
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.
Updates to Rulemaking and Waiver Procedures and Expansion of the Equivalent Level of Safety Option
This action streamlines and improves commercial space transportation regulations' general rulemaking and petition procedures to better reflect current practice; reorganizes the regulations for clarity and flow; and allows petitioners to file their petitions to the FAA's Office of Commercial Space Transportation electronically. Further, it expands the option to satisfy commercial space transportation requirements by demonstrating an equivalent level of safety to the regulatory requirements. These changes are necessary to ensure that the regulations regarding petitions are clear and current, and that the commercial space launch industry is more easily able to request approvals of safe alternative means of regulatory compliance.
Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of multiple in-flight departures of the aft belly fairing access panels. This proposed AD would require modification of the aft belly fairing access panels. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report indicating that certain lanyards for the passenger oxygen masks located in the airplane's entry area are too long. This AD requires replacement of certain oxygen mask lanyards with shorter lanyards. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318 series; Model A319 series; Model A320 series; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This proposed AD was prompted by reports of multiple angle of attack (AoA) probe blockages. This proposed AD would require all elevator aileron computer (ELAC) units to be upgraded with new software, or replaced with upgraded units. We are proposing this AD to address the unsafe condition on these products.
