Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) (type certificate previously held by Turbomeca, S.A.) Model Makila 1A, Makila 1A1, and Makila 1A2 engines. This proposed AD was prompted by a determination that the accumulated service life of certain critical parts was underestimated. This proposed AD would require determining the recalculated service life of certain critical parts, would require replacing the parts if necessary, and would also specify conditions for installing the parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Safety Fitness Determinations; Virtual Public Listening Sessions
FMCSA announces that it will host two virtual public listening sessions pertaining to development of an updated methodology to determine when a motor carrier is not fit to operate commercial motor vehicles in or affecting interstate commerce. Specifically, the Agency would like to hear from members of the public on issues of concern relating to the current Safety Fitness Determination (SFD), including, for example, the three-tiered rating system (Satisfactory, Unsatisfactory, Conditional) versus changing to a proposed single rating only when a carrier is found to be Unfit; utilizing inspection data and FMCSA's Safety Measurement System (SMS); incorporating driver behavior into SFD ratings; and revising the list of safety violations used to calculate the rating, and adjusting the weights allocated to particular violations including increasing the weight for unsafe driving violations. In a separate notice, FMCSA announced and provided registration information for a related in-person listening session on the same topics to be held in June 2024.

Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, and -300F series airplanes. This proposed AD was prompted by a report of a main landing gear (MLG) collapse event following maintenance where a grinder was operating outside of its input parameters, resulting in possible heat damage to the outer cylinder of the MLG. This proposed AD would require replacing any affected outer cylinders. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company (Boeing) Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747- 400F, 747SP, and 747SR series airplanes. This proposed AD was prompted by a report of improper inner diameter grinding of landing gear outer cylinders, resulting in possible heat damage to the outer cylinder of the nose landing gear (NLG), body landing gear (BLG), and wing landing gear (WLG). This proposed AD would require replacing any affected outer cylinders. 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 certain Embraer S.A. (Embraer) Model EMB-505 airplanes. This proposed AD was prompted by analysis of the left-hand (LH) refreshment center and LH forward cabinet that identified the need for installing structural reinforcements. This proposed AD would require installing structural reinforcements as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
