Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires inspecting all barrel nuts to determine if the barrel nuts have a certain marking, inspecting affected bolts to determine if the bolts are pre-loaded correctly, and replacing all hardware if the pre-load is incorrect. For airplanes on which the pre-load is correct, this AD requires doing repetitive visual inspections for cracking of the barrel nuts and cradles and replacing all hardware for all cracked barrel nuts. This AD also requires replacement of all hardware for certain affected barrel nuts that do not have cracking, which would end the repetitive inspections for those airplanes. This AD also provides an optional replacement for all affected barrel nuts. This AD results from reports of cracking in the barrel nuts at the four primary front spar wing-to-fuselage attachment joints. We are issuing this AD to detect and correct cracking of the barrel nuts at the wing front spar wing-to- fuselage joints, which could result in reduced structural integrity of the wing-to-fuselage attachments and consequent detachment of the wing.
Airworthiness Directives; Lockheed Model 382, 382B, 382E, 382F, and 382G Series Airplanes
This document announces a reopening of the comment period for the above-referenced NPRM. The NPRM proposed the adoption of a new airworthiness directive for all Lockheed Model 382, 382B, 382E, 382F, and 382G series airplanes. That NPRM invites comments concerning the proposed requirements for revising the FAA-approved maintenance inspection program to include inspections that will give no less than the required damage tolerance rating for each structural significant item (SSI), doing repetitive inspections to detect cracks of all SSIs, and repairing cracked structure. This reopening of the comment period is necessary to provide additional opportunity for public comment on the proposed requirements of that NPRM.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP Series Airplanes
We propose to adopt a new airworthiness directive (AD) for all Boeing Model 747 airplanes listed above. This proposed AD would require repetitive inspections for broken or missing fasteners in the single- row hinge fasteners of the forward and aft cargo doors, and related investigative/corrective actions. This proposed AD results from reports of broken and missing fasteners in the hinges of the forward and aft cargo doors in both the body hinge segments and the door hinge segments. We are proposing this AD to detect and correct broken or missing fasteners in the hinge segments with a single fastener row, which could lead to opening of the cargo door during flight and result in rapid decompression of the airplane.
Airworthiness Directives; Airbus Model A300, A310, and A300-600 Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Notice of Intent To Rule on Request To Release Airport Property at Monroe Regional Airport, Monroe, LA.
The FAA proposes to rule and invites public comment on the release of land at Monroe Regional Airport under the provisions of title 49, U.S.C. section 47153(c).
