Airworthiness Directives; The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 737-100, -200, -200C, -300, - 400, and -500 series airplanes. The existing AD currently requires repetitive inspections to find cracks, fractures, or corrosion of each carriage spindle of the left and right outboard mid-flaps, and corrective action if necessary. The existing AD also currently requires repetitive gap checks of the inboard and outboard carriage of the outboard mid-flaps to detect fractured carriage spindles, and corrective actions if necessary. This proposed AD would require any new or serviceable carriage spindle installed per the requirements of the existing AD to meet minimum allowable diameter measurements taken at three locations. This proposed AD also would require new repetitive inspections, measurements, and overhaul of the carriage spindles, and applicable corrective actions. In addition, this proposed AD would require replacing any carriage spindle when it has reached its maximum life limit. This proposed AD results from reports of fractures that resulted from stress corrosion and pitting along the length of the spindle and spindle diameter, and additional reports of corrosion on the outboard flap carriage spindles. We are proposing this AD to detect and correct cracked, corroded, or fractured carriage spindles, and to prevent severe flap asymmetry, which could result in reduced control or loss of controllability of the airplane.
Production and Airworthiness Approval, Part Marking, and Miscellaneous Amendments; Correction
The FAA is making certain corrections to the Certification Procedures and Identification Requirements for Aeronautical Products and Articles final rule published on October 16, 2009 (74 FR 53368). The purpose of that final rule was to update and standardize those requirements for production approval holders (PAHs), revise export airworthiness approval requirements to facilitate global manufacturing, move all part marking requirements from part 21 to part 45, and amend the identification requirements for products and articles. In the amendatory language and the preamble, we inadvertently referred to incorrect paragraphs and text. This document corrects those errors.
Airworthiness Directives; International Aero Engines AG (IAE) V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 Turbofan Engines; Correction
The FAA is correcting an NPRM, which published in the Federal Register. That NPRM applies to IAE V2500-A1, V2522-A5, V2524-A5, V2525- D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 turbofan engines. The docket number is incorrect in three locations. This document corrects the docket number in those three locations. In all other respects, the original document remains the same.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
