The Proposed Special Conditions
Federal Aviation Administration
Accordingly, the Federal Aviation Administration FAA proposes the following special conditions as part of the type certification basis for the Bombardier Model CL6002B16
airplane with the LAIRCM system, as modified by Pro Star Aviation.
1. The system must have means that prevent the inadvertent activation of the system on the ground, including during airplane maintenance and ground handling. Such means must address all foreseeable failure modes and operating and maintenance errors.
2. The system must be designed so that its operation in-flight does not result in damage to the airplane or other aircraft, or injury to any person.
Operation of the system must not be capable of compromising continued safe flight and landing of other aircraft and the airplane on which it is installed, either by direct damage, laser-reflective damage, or through distraction or incapacitation of crew.
3. Laser-safety information for maintaining or servicing the airplane must be prominently placarded on the airplane or LAIRCM system at the location of the laser installation.
4. Instructions for continued airworthiness for installation, removal, and maintenance of the LAIRCM system must contain warnings appropriate to the laser classification concerning the hazards associated with exposure to laser radiation. This includes instructions regarding potential hazards to personnel who are using optical magnification devices such as magnifying glasses or binoculars.
5. The airplane flight manual supplement AFMS must describe the intended functions of the installed laser systems, to include identifying the intended operations and phases of flight. The AFMS must state, CAUTION: The operation of the installed laser system could pose significant risk of injury to others while in proximity to other aircraft, airports, and populated areas.

Airworthiness Directives; Leonardo S.p.a. Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Notice of proposed rulemaking NPRM.
AGENCY:

The FAA proposes to adopt a new airworthiness directive AD for certain Leonardo S.p.a. Model AB139
and Model AW139 helicopters. This proposed AD was prompted by a report that, during a post-flight inspection of an in-service helicopter, a tail rotor slider assembly was found fractured, and the bushing and the actuator rod in the tail rotor servo were partially damaged. This proposed AD would require an inspection of the tail rotor slider assembly for corrosion and signs of circumferential refinishing and, depending on the findings, replacement of the tail rotor slider assembly with a serviceable part or repetitive inspections of the of the tail rotor slider assembly for corrosion and signs of circumferential refinishing, as specified in a European Aviation Safety Agency now European Union Aviation Safety Agency EASA AD, which is proposed for incorporation by reference IBR. The FAA is proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by August 9, 2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
