Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Airplanes
We are rescinding an airworthiness directive (AD) for PIAGGIO AERO INDUSTRIES S.p.A. Model P-180 airplanes. The rescinded AD resulted from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as partial detachment of the inner protective film of the composite nacelles. Since issuance of the rescinded AD, we have determined that the unsafe condition does not exist or is not likely to develop on affected type design airplanes.
Special Conditions: Embraer, S.A., Model EMB-550 Airplane; Side-Facing Seats; Installation of Airbag Systems in Shoulder Belts
These special conditions are issued for the Embraer S.A. Model EMB-550 airplane. This airplane will have a novel or unusual design feature associated with multiple-place and single-place side-facing seats and the installation of airbag systems in the shoulder belts. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; Hamilton Standard Division and Hamilton Sundstrand Corporation Propellers
We are adopting a new airworthiness directive (AD) for Hamilton Standard Division model 6/5500/F and 24PF and Hamilton Sundstrand Corporation model 14RF, 14SF, 247F, and 568F series propellers. This AD was prompted by the amount of corrosion detected during major inspections (MI). This AD requires incorporating inspections, based on a calendar time, into the propeller maintenance schedule. We are issuing this AD to prevent corrosion that could result in propeller failure and loss of airplane control.
