Airworthiness Directives; BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This proposed AD would require modifying the wiring of the starter-generator terminal block. This proposed AD results from a report of total electrical failure just as the airplane landed. We are proposing this AD to prevent total electrical failure and consequent reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-200B, 747-200C, 747-200F, 747-400F, 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, 747-400F, 747SR, and 747SP series airplanes, without a stretched upper deck or stretched upper deck modification. This proposed AD would require detailed and high-frequency eddy current inspections for cracks at the outboard ends of each affected tension tie and of the surrounding structure, and related investigative and corrective actions if necessary. This proposed AD results from a report of a crack in the tension tie at the body station 820 frame connection, and cracks found on the Boeing 747SR fatigue-test airplane in both the tension ties and frames at the tension tie to frame connections at body stations 800, 820, and 840. We are proposing this AD to find and fix cracks in the tension ties, which could lead to cracks in the skin and body frame and result in rapid in-flight depressurization of the airplane.
Airworthiness Directives; Boeing Model 747-400 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-400 series airplanes. This proposed AD would require doing a conductivity test of the upper deck floor beam at station 400 to identify the floor beam material. If the floor beam is manufactured from 7050 aluminum alloy, this proposed AD would also require inspecting the upper deck floor beam and certain fastener holes at the floor beam upper chord for cracking; repairing any cracking if necessary; and doing a preventative modification. This proposed AD results from several reports indicating that fatigue cracking was found in upper deck floor beams made from 7050 aluminum alloy. We are proposing this AD to find and fix cracking in the upper deck floor beam, which could extend and sever the floor beam. A severed floor beam could result in loss of controllability and rapid decompression of the airplane.
Notice of Intent to Request Renewal From the Office of Management and Budget (OMB) of Five Current Public Collections of Information
In compliance with the Paperwork Reduction Act (44 U.S.C. 3501 et seq.) the FAA invites public comment on five currently approved public information collections which will be submitted to OMB for renewal.
Establishment of Class D Airspace; Eau Claire, WI
This document establishes Class D airspace at Eau Clair, WI. A control tower is currently under construction at Chippewa Valley Regional Airport. Controlled airspace extending upward from the surface is required when the control tower is operational. This action establishes a radius of controlled airspace for Eau Clair, WI.
Modification of Class E Airspace; Washington, MO
This document confirms the effective date of the direct final rule which revises Class E airspace at Washington, MO.
Modification of Class E Airspace; Abilene Municipal Airport, KS
This document confirms the effective date of the direct final rule which revises Class E airspace at Abilene Municipal Airport, KS.
Modification of Class E Airspace; Meade Municipal Airport, KS
This document confirms the effective date of the direct final rule which revises Class E airspace at Meade Municipal Airport, KS
Airworthiness Directives; Boeing Model 737-100, -200, -200C, and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, and -300 series airplanes. This AD requires repetitive detailed inspections to detect discrepancies of the retaining pin lugs on the support fitting of the main landing gear (MLG) beam, and rework of the support fitting, or replacement of the fitting if necessary. This AD is prompted by reports of discrepancies of the lugs. We are issuing this AD to prevent separation of the support beam of the MLG from the rear spar, which could cause cracking of the MLG support fitting and a consequent leak in the wing fuel tank or collapse of the MLG.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100& 440) airplanes, that requires performing an inspection of the electrical harnesses of the spoiler and the brake pressure sensor unit on both sides of the wing root to detect any chafing or wire damage, and repairing or replacing any damaged or chafed harness or wire with a new harness, as applicable. This action also provides/requires a terminating modification for the one-time inspection. The actions specified by this AD are intended to detect and correct chafing of the electrical cables of the spoiler and brake pressure sensor unit on both sides of the wing root, which could result in loss of the flight control system and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
