Airworthiness Directives; Eurocopter France Model SA341G, SA342J, and SA-360C Helicopters
This amendment proposes superseding an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters that currently requires replacing each affected main rotor head torsion tie bar (tie bar) with an airworthy tie bar and revising the limitations section of the maintenance manual by adding life limits for certain tie bars. This action would retain the current requirements and reduce life limits of another part-numbered tie bar. This proposal is prompted by the FAA determination, after reviewing the manufacturer's data, that another part-numbered tie bar should be included in the applicability of the AD. The actions specified by the proposed AD are intended to prevent failure of a tie bar, loss of a main rotor blade, and subsequent loss of control of the helicopter.
Airworthiness Directives; MD Helicopters, Inc. Model MD900 Helicopters
This document proposes superseding an existing airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model MD900 helicopters. That AD currently requires reducing the life limit of certain Notar fan system tension-torsion (TT) straps. That AD also requires, at a specified time interval, removing each affected TT strap from the helicopter, doing a visual and X-ray inspection, and replacing any unairworthy part before further flight. This AD would require the same actions as the existing AD, but would also require revising the life limit on the component history card or equivalent record, doing repetitive visual and X-ray inspections, and would remove reporting requirements. This proposal is prompted by two in-flight TT strap failures. The actions specified by the proposed AD are intended to prevent failure of a TT strap, loss of directional control, and subsequent loss of control of the helicopter.
Notice of Approval of Finding of No Significant Impact (FONSI) on a Final Environmental Assessment (Final EA); Lake in the Hills Airport, Lake in the Hills, IL
The Federal Aviation Administration (FAA) is issuing this notice to advise the public of the approval of a Finding of No Significant impact (FONSI) on an Environmental Assessment for proposed Federal actions at Lake in the Hills Airport, Lake in the Hills, Illinois. The FONSI specifies that the proposed Federal actions and local development projects are consistent with existing environmental policies and objectives as set forth in the National Environmental Policy Act of 1969 and will not significantly affect the quality of the environment. A description of the proposed Federal actions is: (a) To issue an environmental finding to allow approval of the Airport Layout Plan (ALP) for the development items listed below; (b) approval of the Airport Layout Plan (ALP) for the development items listed below; and (c) establish eligibility of the Lake in the Hills Airport Authority to compete for Federal funding for the development projects depicted on the Airport Layout Plan. The specific items in the local airport development project include: Acquire approximately 102 acres of land in fee simple title and approximately 57 acres of easements; these actions include relocation assistance, as required; install perimeter fencing to control deer and preserve security; Improve Runway 26 Safety Area, Stage 1acquisition of land needed; Remove Airport design deviations and FAR Part 77 obstructions, Stage 1acquisition of land needed; Replace Airport rotating beacon; Improve Runway 26 safety area, Stage 2relocation of Pyott Road; Remove Airport design deviations and 14 CFR part 77 obstructions, Stage 2acquisition of land needed; Install AWOS-III P/T to support 14 CFR part 135 Operators; Remove Airport design deviations and 14 CFR part 77 Obstructions, Stage 3removal of buildings and objects; construct storm water management/detention system (dry bottom)multi-phased construction; construct replacement electrical vault; construct parallel taxiway (for temporary runway use) to meet design standards; install MITL taxiway edge lighting and guidance signs; Remove Airport design deviations and 14 CFR part 77 obstructions, Stage 4construction of replacement aircraft apron, Phase 1; Remove Airport design deviations and 14 CFR part 77 obstructions, Stage 5relocation of existing access road to serve new replacement terminal area; construct auto parking in the new replacement terminal areamulti-phased construction; Widen Runway 8-26 to 100 feet; shift runway ends to East to meet design standards (runway safety area, object free area, and pavement width); install MIRL runway edge lights, and PAPI-4 approach lights, REIL lights and supplemental wind cones at each runway end; Remove Airport design deviations and 14 CFR part 77 obstructions, Stage 6construction of replacement aircraft apron, Phase 2; construct new and replacement aircraft hangar pavements in the new replacement terminal areamulti-phased construction; construct new and replacement aircraft storage hangars in the new replacement terminal areamulti-phased construction; construct new and replacement Fixed Based Operator/Aircraft Maintenance hangars in the new replacement terminal areamulti-phased construction; construct replacement public terminal building in the new replacement terminal area; construct replacement aircraft fuel storage/dispensing facility in the new replacement terminal area; construct new Airport maintenance complex; Extend municipal water and sanitary sewer utilities to existing-to-remain and new building facilities requiring domestic water service and sanitary sewer collection and/or fire protection.
