Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-28-140, PA-28-150, PA-28- 151, PA-28-160, PA-28-161, PA-28-180, PA-28-181, PA-28-235, PA-28R-180, PA-28R-200, PA-28R-201, PA-28R-201T, PA-28RT-201, PA-28RT-201T, PA-32- 260, and PA-32-300 airplanes. This proposed AD was prompted by a report of a fatigue crack found in a visually inaccessible area of the lower main wing spar cap. This proposed AD would require calculating the factored service hours for each main wing spar to determine when an inspection is required, inspecting the lower main wing spar bolt holes for cracks, and replacing any cracked main wing spar. We are proposing this AD to address the unsafe condition on these products.
Primary Category Airworthiness Design Standards; Vertical Aviation Technologies (VAT) Model S-52L Rotorcraft
These airworthiness design standards are issued to Vertical Aviation Technologies (VAT) for certification of the Model S-52L rotorcraft under the regulations for primary category aircraft.
Establishment of Class E Airspace; Maurice, IA
This action establishes Class E airspace extending upward from 700 feet above the surface at Sioux County Regional Airport, Maurice, IA. Controlled airspace is necessary to accommodate new standard instrument approach procedures developed at Sioux County Regional Airport, for the safety and management of instrument flight rules (IFR) operations at this airport.
Use of Automatic Dependent Surveillance-Broadcast (ADS-B) Out in Support of Reduced Vertical Separation Minimum (RVSM) Operations
This action revises the FAA's requirements for application to operate in RVSM airspace. The amendment eliminates the requirement for operators to apply for an RVSM authorization when their aircraft are equipped with qualified ADS-B Out systems and meet specific altitude keeping equipment requirements for operations in RVSM airspace. This action recognizes the enhancements in aircraft monitoring resulting from the use of ADS-B Out systems and responds to requests from operators to eliminate the burden and expense of the current RVSM application process for aircraft equipped with qualified ADS-B Out systems.
