Airworthiness Directives; Hamilton Sundstrand Corporation Propellers
The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) that had applied to certain Hamilton Sundstrand Corporation 14SF-7, 14SF-15, and 14SF-23 series propellers. The NPRM had applied to those propellers using certain Hamilton Sundstrand Corporation auxiliary pumps and motors (auxiliary feathering pumps). The proposed action would have required removal of certain serial numbers (S/Ns) of auxiliary feathering pumps from service. Since we issued the NPRM, we attended a meeting sponsored by Hamilton Sundstrand Corporation, which provided additional information regarding the unsafe condition. The information included results from bond strength tests that predicts a significantly lower fleet risk than the prior qualitative analysis. Accordingly, we withdraw the proposed rule.
Modification of Class B Airspace; Las Vegas, NV
This action modifies the Las Vegas, NV, Class B airspace area to ensure the containment of large turbine-powered aircraft within Class B airspace, reduce air traffic controller workload, and reduce the potential for midair collision in the Las Vegas, NV, terminal area.
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.
Airworthiness Directives; the Boeing Company
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 747 series airplanes. The existing AD currently requires repetitive detailed inspections to detect cracking in certain fuselage upper deck tension ties, repair or modification of any cracked tension ties, and repetitive inspections of repaired and modified tension ties and repair or modification if necessary. The existing AD also provides for optional terminating action for the repetitive detailed inspections of tension ties that have not been repaired or modified. This proposed AD was prompted by an evaluation by the design approval holder indicating that the upper deck tension ties of the fuselage are subject to widespread fatigue damage. This proposed AD would retain the repetitive inspections, mandate the previously optional terminating modification, and add, for tension ties that have not been repaired or modified, repetitive inspections that must be done concurrently with the existing repetitive inspections. We are proposing this AD to prevent widespread fatigue damage of certain fuselage upper deck tension ties, which could result in reduced structural integrity of the airplane.

Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding airworthiness directive (AD) 2011-13-08 for certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2011-13- 08 required a free-play check for excessive free-play of the shaft swaged bearing installed in the tailstock end of each elevator power control unit (PCU), and replacing any PCU on which the bearing exceeds allowable limits with a serviceable PCU. This new AD adds airplanes to the applicability from that of AD 2011-13-08. This AD was prompted by a determination that additional airplanes are affected by the identified unsafe condition. We are issuing this AD to detect and correct excessive free-play of the swaged bearings, which could lead to excessive airframe vibrations and difficulties in pitch control, and consequent loss of controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and 747-400F series airplanes. This AD was prompted by reports of cracking in the outboard flange of the longeron extension fittings, which attach to the wing-to-body fairing support frame. This AD requires repetitive inspections of the longeron extension fittings for cracking, and corrective actions if necessary. We are issuing this AD to detect and correct cracks in the longeron extension fittings, which can become large and adversely affect the structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This AD was prompted by reports of cracks on the elevator rear spar stiffener assembly. This AD requires repetitive detailed inspections for cracking of the elevator rear spar stiffener assembly, and corrective actions if necessary. We are issuing this AD to detect and correct cracking of the elevator rear spar stiffener assembly, which could adversely affect elevator structural stiffness, which could lead to elevator vibration and possible interference with the tab control rod. These conditions could result in flutter and consequent loss of control of the airplane.
Airworthiness Directives; Learjet Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Learjet Inc. Model 45 airplanes. This AD was prompted by a report that the fire barrier seal on the external baggage door does not seal the surrounding door structure due to incorrect positioning of the barrier. This AD requires modifying the fire seal on the baggage door, including doing inspections of the fire seal for correct contact and corrective action if necessary. We are issuing this AD to prevent improper sealing of the baggage door, which could increase the risk of an uncontained fire in the baggage compartment.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This AD was prompted by reports of spanwise cracks and corrosion in the wing center box upper skin and rear spar upper chord between left buttock line (LBL) 70.50 and right buttock line (RBL) 70.50 at body station (STA) 870. This AD requires repetitive inspections of the wing center box for cracking around certain fastener rows on the rear spar upper chord horizontal flange; for certain airplanes, repetitive inspections for cracking of the rear spar upper chord radius; for certain other airplanes, repetitive inspections for damage, cracking, and corrosion of the pressure seal; and repair if necessary. We are issuing this AD to detect and correct cracking and corrosion of the upper skin and rear spar upper chord of the wing center box, which could result in loss of the airplane wing and consequent loss of control of the airplane.
