Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to all Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engine models with certain second-stage high-pressure turbine (HPT) air seals installed. The time required to perform the initial eddy current inspection (ECI) in the Compliance section is incorrect. This document corrects that error. In all other respects, the original document remains the same.
Membership in the National Parks Overflights Advisory Group Aviation Rulemaking Committee
The Federal Aviation Administration (FAA) and the National Park Service (NPS) are inviting interested persons to apply to fill two existing openings and one upcoming opening on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). The two existing openings represent environmental concerns and the upcoming opening represents Native American interests. Selected members will each serve 3-year terms.
Twenty Seventh Meeting: RTCA Special Committee 213, Enhanced Flight Vision Systems/Synthetic Vision Systems (EFVS/SVS)
The FAA is issuing this notice to advise the public of the twenty seventh meeting of the RTCA Special Committee 213, Enhanced Flight Vision Systems/Synthetic Vision Systems (EFVS/SVS).
Seventeenth Meeting: RTCA Special Committee 222, AMS(R)S
The FAA is issuing this notice to advise the public of the seventeenth meeting of the RTCA Special Committee 222, Inmarsat AMS(R)S. The purpose of this meeting is threefold. First, we will consider the draft Change 4 to DO-210D. The draft will be submitted to the workspace no later than close of business Eastern time on January 12. Second, we will consider a work plan to progress development of Iridium NEXT material for DO-343, as approved by the PMC on December 16, 2014. Third, we will consider a work plan to progress cooperation with Eurocae WG-82, as approved by the PMC on December 16, 2014.
Establishment of Policy Regarding Aircraft Dispatcher Certification Courses
This notice announces the availability of additional supporting documents and an extension of the comment period for the proposed policy applicable to Aircraft Dispatcher Certification Courses, which was published in this docket on October 22, 2014.
Airworthiness Directives; International Aero Engines AG Turbofan Engines
We propose to supersede airworthiness directive (AD) 2012-09- 09 that applies to all International Aero Engines AG (IAE) V2500-A1, V2525-D5, and V2528-D5 turbofan engines, and certain serial numbers (S/ Ns) of IAE V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530- A5, and V2533-A5 turbofan engines. AD 2012-09-09 currently requires cleaning, eddy current inspection (ECI) or fluorescent penetrant inspection (FPI), and initial and repetitive ultrasonic inspections (USIs) of certain high-pressure compressor (HPC) stage 3 to 8 drums, as well as replacement of the drum attachment nuts. Since we issued AD 2012-09-09, we discovered that additional attachment nuts for certain HPC stage 3 to 8 drums are affected. This proposed AD would expand the affected population for initial and repetitive USIs of the HPC stage 3 to 8 drum, revise the inspection intervals, require removal of the affected attachment nuts and any HPC stage 3 to 8 drum found cracked, and require a mandatory terminating action. We are proposing this AD to prevent failure of the HPC stage 3 to 8 drum, which could result in uncontained drum failure, damage to the engine, and damage to the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-300, 747-400, 747-400D, and 747SR series airplanes. This AD was prompted by a report of a cracked reveal made from a casting found within a group of airplanes that should have machined reveals made only from 6061 aluminum. This AD requires an inspection to determine the material of the number 3 main entry door (MED) corner reveal, repetitive inspections of certain reveals for cracking, and corrective action if necessary. This AD also requires repetitive inspections for cracking of 6061 machined aluminum one-piece corner reveals, and replacement with 6061 machined aluminum two-piece corner reveals if necessary, which terminates certain repetitive inspections. We are issuing this AD to detect and correct fatigue cracking of the lower forward corner reveal of the number 3 MEDs, which could lead to the door escape slide departing the airplane when the door is opened and the slide is deployed, and consequent injuries to passengers and crew using the door escape slide during an emergency evacuation.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 97-11-07 and AD 99-18-23, which apply to all The Boeing Company Model MD-90-30 airplanes. AD 97-11-07 and AD 99-18-23 required revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate certain compliance times for principal structural element (PSE) inspections and replacement times for safe-life limited parts. This new AD also requires revising the maintenance or inspection program to incorporate a new PSE requirement for the rear spar caps of the horizontal stabilizer and its associated inspections, which would terminate certain inspections of the horizontal stabilizer rear spar. This AD was prompted by an analysis of data that identified a need to introduce a new PSE requirement for the rear spar caps of the horizontal stabilizer. We are issuing this AD to detect and correct fatigue cracking of PSEs and certain safe-life limited parts, which could adversely affect the structural integrity of the airplane.
Airworthiness Directives; Alpha Aviation Concept Limited Airplanes
We are adopting a new airworthiness directive (AD) for Alpha Aviation Concept Limited Model R2160 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 paint adherence defects inside the engine air intake box and cohesion defects inside the laminated ducting from the filter to the air intake box. We are issuing this AD to require actions to address the unsafe condition on these products.
