Federal Aviation Administration February 23, 2018 – Federal Register Recent Federal Regulation Documents

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for a new information collection. The collection involves an internet based tool, the Safety Assurance System (SAS) External Portal. The SAS External Portal is used by the FAA's Office of Flight Standards to conduct initial certification, routine surveillance, and certificate management for applicants and certificate holders. The information to be collected will be used to better facilitate efficient certification, surveillance and certificate management activities.

We propose to adopt a new airworthiness directive (AD) for The Boeing Company Model 787 series airplanes powered by Rolls Royce Trent 1000 engines. This proposed AD was prompted by a report of failures of the inner fixed structure (IFS) forward upper fire seal and damage to thermal insulation blankets in the forward upper area of the thrust reverser (TR). This proposed AD would require an inspection to determine the part number of the IFS forward upper fire seal, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This AD was prompted by a report that a jammed control cable prevented the full extension of the nose landing gear (LG). This AD requires a general visual inspection of the LG handle teleflex cable conduit connector for the presence of a grease nipple, a maintenance records check of affected airplanes, a detailed inspection for corrosion and damage of the LG handle teleflex cable, and corrective actions if necessary. This AD also requires revising the maintenance or inspection program, as applicable. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747- 200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This AD was prompted by a report of incidents involving fatigue cracking in transport category airplanes that are approaching or have exceeded their design service objective and a structural reevaluation by the manufacturer that identified additional structural elements that qualify as structural significant items (SSIs). This AD requires revising the maintenance or inspection program, as applicable, to include inspections that will give no less than the required damage tolerance rating (DTR) for certain SSI, performing repetitive inspections to detect cracks of all SSIs, and repairing cracked structures if necessary. Additionally, this AD requires all cracks involving an SSI or related structure in close vicinity to the SSI to be reported to Boeing. We are issuing this AD to address the unsafe condition on these products.
