Airworthiness Directives; Airbus A318, A319, A320, and A321. Final rule; correction. SUMMARY: The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on March 24, 2009 (74 FR 12247). The error resulted in publication of an incorrect AD number. This AD applies to certain Airbus Model A318, A319, A320, and A321 airplanes. This AD requires the installation of improved cockpit door latch/striker assemblies. Effective April 28, 2009.

Airworthiness Directives; Airbus A318-100 and A319-100; A320-111; A320-200; and A321-100 and A321-200. Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A318-100 and A319-100 series airplanes; A320-111 airplanes; A320-200 series airplanes; and A321-100 and A321- 200 series airplanes. That AD currently requires a one-time inspection of the horizontal hinge pin of the 103VU electrical panel in the avionics compartment to determine if the hinge pin can move out of the hinge, and related investigative and corrective actions if necessary. This new AD instead requires installing a hinge pin stopper on the internal door of the 103VU electrical panel. This AD results from a report indicating that electrical wire damage was found in the 103VU electrical panel due to contact between the hinge pin and the adjacent electrical wire harness. We are issuing this AD to prevent contact between the horizontal hinge pin and the adjacent electrical wire harness, which could result in damage to electrical wires, and consequent arcing and/or failure of associated systems. This AD becomes effective June 4, 2009.

Airworthiness Directives; Cessna Aircraft Company (Type Certificate Previously Held by Columbia Aircraft Manufacturing (Previously The Lancair Company)) Models LC40-550FG. Final rule; request for comments. SUMMARY: This AD requires you to repetitively inspect the rudder hinges and the rudder hinge brackets for damage, i.e., cracking, deformation, and discoloration. If damage is found during any inspection, this AD also requires you to replace the damaged rudder hinge and/or rudder hinge bracket. This AD results from reports that cracked lower rudder hinge brackets were found on two of the affected airplanes. We are issuing this AD to detect and correct damage in the rudder hinges and the rudder hinge brackets, which could result in failure of the rudder. This failure could lead to loss of control.This AD becomes effective on May 11, 2009.

Emergency AD (NZ): Bell 407. Airworthiness Directive DCA/BELL407/47 SUMMARY: This emergency AD is prompted by the manufacturer and Transport Canada reporting that during a recent preflight inspection it was found that the swashplate link assembly bearing P/N 406-310-403-101 had moved in the lever race and come into contact with the swashplate support. This AD requires an inspection of the anti-drive link assembly to ensure the bearing is correctly staked. To prevent failure of the anti-drive link assembly P/N 406-010- 432-101 due to possible movement of bearing P/N 406-310-403-101 which could result in loss of aircraft control, accomplish the following: Inspect the anti-drive link assembly P/N 406-010-432-101 to ensure the bearing P/N 406-310-403-101 is correctly staked in the link assembly per Bell Helicopter ASB 407-09-87 dated 27 March 2009 or later Transport Canada approved revisions.

Correct any defects found per ASB 407-09-87 before further flight. (Transport Canada AD CF-2009-14 refers) COMPLIANCE: Within the next 10 hours TIS or by 6 June 2009 whichever is the sooner, unless previously accomplished.

Airworthiness Directives; Pratt & Whitney (PW) JT9D-7R4 Series Turbofan Engines. Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for PW JT9D-7R4 series turbofan engines. That AD currently requires removing certain reduced cooling flow 2nd stage high-pressure turbine (HPT) vane assemblies installed in certain 2nd stage HPT vane cluster assemblies. It also requires a visual and a fluorescent penetrant inspection (FPI) of the 2nd stage HPT air seal assembly, part number (P/N) 815097. This AD requires a visual and FPI of all P/N 2nd stage HPT air seal assemblies that were used with reduced cooling flow 2nd stage HPT vane assemblies. This AD results from PW identifying additional P/N air seal assemblies that are affected by the unsafe condition. We are issuing this AD to prevent uncontained failure of the 2nd stage HPT air seal assembly, leading to engine in-flight shutdown and damage to the airplane. This AD becomes effective June 9, 2009.

NATA President James Coyne recently appeared before the National Fire Protection Association's (NFPA) Technical Committee on Airport Facilities to discuss the impact that changes to NFPA 409, Standard on Aircraft Hangars, could have on the general aviation industry. The committee is considering changes to NFPA 409 that would require the installation of automatic sprinkler systems in all new hangars of less than 12,000 square feet. Coyne said there would be detrimental effect on the development and construction of new hangars. In a recent NATA survey, over 77% of responding members stated that the costs associated with implementation of these changes would prevent the construction of new hangars. Coyne also expressed concern over the current requirement for foam fire suppression systems in all hangars over 12,000 square feet

AD/AWB (CASA): Robinson R-22 Applicability: This Bulletin refers to Robinson R22 helicopters of all models. The purpose of this Bulletin is to recommend that registered operators and maintainers of R22s consider the need to continue performing a maintenance operation previously mandated by Australian AD. Background: AD/R22/27 was issued in 1986 following an accident caused by the vertical fin separating from the tail-boom in flight. A second report of cracking of the fin attachment bracket was also received. AD/R22/27 was not based on Robinson service documents. In 2009 a review was conducted of all Airworthiness Directives applicable to R22 helicopters. AD/R22/27 was cancelled because it was not based on a foreign Airworthiness Directive or Robinson service document, and because there have been very few defects reported. Maintenance: The following inspection should be considered on helicopters with vertical fin to horizontal stabilizer attachment brackets that have exceeded 500 hours time in service. At each scheduled inspection for issue of a new maintenance release, remove the lower vertical fin and: (a) visually inspect for fretting on the faying surfaces in the vicinity of the fin attachment bolts; (b) inspect the fin attachment brackets in the horizontal stabilizer for cracking in the vicinity of the fin attachment bolts using a dye penetrant technique. Recommendation: It is recommended that owners and maintainers of R22 helicopters remain aware of this maintenance task and consider it carefully when planning maintenance of these helicopters.

Communication and Area Navigation Equipment (RNAV) Operations in Remote Locations and Mountainous Terrain. Final rule; request for comments. SUMMARY: This final rule amends the regulations to allow the use of the published Obstacle Departure Procedures (ODP) or an alternative procedure or route assigned by Air Traffic Control (ATC). Also, this final rule amends the requirements to facilitate compliance and accurately reflect operating conditions in areas in which the terrain impedes communications. In August 2007, the FAA issued regulations relating to ODPs and Area Navigation equipment (RNAV). Among the amendments, the FAA prohibited Instrument Flight Rules (IFR) takeoffs from airports with published ODPs for the takeoff runway to be used unless the pilot uses the ODP for that runway. Following publication of the rule, the FAA determined that this requirement is unnecessarily restrictive because it prohibits pilots from using Standard Instrument Departure (SID) procedures and air traffic control (ATC) radar vectoring. The final rule also amended the communication and navigation equipment requirements for aircraft operations under Visual Flight Rules (VFR). The FAA determined that compliance with the new communications requirements may not be possible in remote locations and areas of mountainous terrain. This final rule is adopted without prior notice and public comment, but the public may comment prior to the effective date of the rule. DATES: Effective Date--This amendment becomes effective June 30, 2009. Comments Due--Comments must be received by June 1, 2009.
