Airworthiness Directives; Boeing Model 777 Airplanes
Document Number: E8-12717
Type: Rule
Date: 2008-06-11
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Boeing Model 777 airplanes. This AD requires an inspection to determine the manufacturer and manufacture date of the oxygen masks in the center and outboard passenger service units, crew rests, and lavatory and flight attendant oxygen boxes, as applicable. This AD also requires related investigative/corrective actions if necessary. This AD results from a report that several passenger masks with broken in-line flow indicators were found following a mask deployment. We are issuing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.

Airworthiness Directives; Cessna Aircraft Company Model 525 Airplanes
Document Number: E8-12305
Type: Rule
Date: 2008-06-11
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Model 525 airplanes. This AD requires you to inspect for missing firewall sealant between the aft firewall assembly and seal assembly; and, if you find that firewall sealant is missing, seal with firewall sealant between the aft firewall assembly and seal assembly. This AD results from a report that firewall sealant may not have been applied between the aft firewall assembly and seal assembly during manufacture of certain Model 525 airplanes. We are issuing this AD to detect and correct missing firewall sealant between the aft firewall assembly and seal assembly, which could result in failure of the fire extinguishing system to prevent the spread of fire through the firewall gap. This failure could lead to an uncontrolled fire.

Airworthiness Directives; Sikorsky Aircraft Corporation Model S-76A, S-76B, and S-76C Helicopters
Document Number: E8-12414
Type: Proposed Rule
Date: 2008-06-04
Agency: Federal Aviation Administration, Department of Transportation
This document proposes adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-76A, S-76B, and S-76C helicopters. The AD would require an initial and recurring inspections of the tail rotor vertical stabilizer aft spar assembly (aft spar assembly) for a crack, loose or working fasteners, and corrosion, and, if any are found, further inspections of the vertical stabilizer forward spar assembly (forward spar assembly). Repairing or replacing any unairworthy part before further flight would also be required. The action would also require a recurring track-and-balance of the tail rotor. Finally, the proposed AD would require installing a vertical stabilizer modification kit, which would be terminating action for the requirements of the AD. This proposal is prompted by 26 reports of fatigue cracks in the aft spar assembly web and outer caps. The actions specified by the proposed AD are intended to detect and correct an unbalanced or out-of-track tail rotor, which could lead to increased vibrations, a fatigue crack, loss of a portion of the vertical stabilizer and subsequent loss of control of the helicopter.

Airworthiness Directives; Air Tractor, Inc. AT-200, AT-300, AT-400, AT-500, AT-600, and AT-800 Series Airplanes
Document Number: E8-11944
Type: Rule
Date: 2008-06-02
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) to supersede AD 2002-25-09, which applies to certain Air Tractor, Inc. (Air Tractor) AT-250, AT-300, AT-400, and AT-500 series airplanes. AD 2002-25-09 currently requires you to install an overturn skid plate in the cockpit area. Since we issued AD 2002-25-09, we received a report of the bolts attaching the forward end of the original design overturn skid plate to the airframe breaking in an overturn accident. This allowed the skid plate to rotate around the rear attach point and the forward end of the plate to enter the cockpit area. Consequently, this AD would require the installation of a modified skid plate kit or modification to skid plate kits that are already installed, including those already installed on AT-402B, AT-502B, AT-602, and AT-802A series airplanes during production. We are issuing this AD to prevent the front and rear connections of the overturn skid plate to the airplane from breaking, which could allow foreign debris to enter the cockpit during an airplane overturn. This condition, if not corrected, could lead to pilot injury.
