Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-200B, 747-200C, 747- 200F, 747-300, 747SR, and 747SP series airplanes. This proposed AD would require repetitive high frequency eddy current inspections for cracks of the fuselage skin at stringer 5 left and right between stations 340 and 350, and corrective actions if necessary. This proposed AD results from reports of fatigue cracks in the fuselage skin near stringer 5 between stations 340 and 350. We are proposing this AD to detect and correct fatigue cracking of the fuselage skin near stringer 5. Cracks in this area could join together and result in in- flight depressurization of the airplane.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Airbus Model A318, A319, A320, and A321 airplanes. The original NPRM would have superseded an existing AD that currently requires repetitive detailed inspections of the inboard flap trunnions for any wear marks and of the sliding panels for any cracking at the long edges, and corrective actions if necessary. The original NPRM proposed to add airplanes to the applicability in the existing AD and change the inspection type. The original NPRM resulted from a determination that certain airplanes must be included in the applicability of the AD, and that the inspection type must be revised. This new action revises the original NPRM by including airplanes that were inadvertently excluded from the applicability. We are proposing this supplemental NPRM to detect and correct wear of the inboard flap trunnions, which could lead to loss of flap surface control and consequently result in the flap detaching from the airplane. A detached flap could result in damage to the tail of the airplane.
Removal of an Obsolete Reference in Special Federal Aviation Regulation 50-2-Special Flight Rules in the Vicinity of Grand Canyon National Park, AZ
This amendment removes an obsolete reference in Special Federal Aviation Regulation 50-2, Special Flight Rules in the Vicinity of Grand Canyon National Park, AZ. In section 9 of that SFAR, there is a ``Note'' that refers to an informational map of the Special Flight Rules Area (SFRA). This map is no longer available; however, there is an illustrational map of the SFRA in Part 93, Subpart U. Therefore, this technical amendment deletes the reference in SFAR 50-2, which is no longer needed and is confusing to the public.
Executive Committee of the Aviation Rulemaking Advisory Committee; Meeting
The FAA is issuing this notice to advise the public of a meeting of the Executive Committee of the Aviation Rulemaking Advisory Committee.
Standard Instrument Approach Procedures; Miscellaneous Amendments
This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in 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; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires inspecting the carbon-fiber reinforced plastic main landing gear (MLG) door to determine whether certain part numbers are installed. For airplanes having certain doors, this AD requires inspecting the MLG outboard door for cracks, play, and loose sealant/bolts/nuts, and related investigative and corrective actions if necessary. This AD also requires, for airplanes having certain doors, modifying the rod bracket attachment of the MLG outboard door. This AD results from a report of a rod bracket of the MLG door detaching during flight. We are issuing this AD to detect and correct cracks in the rod bracket attachment bolts, which could result in the rod brackets detaching from the MLG door and blocking the proper functioning of the MLG.
