Federal Aviation Administration February 18, 2009 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. The existing AD currently requires repetitive inspections for corrosion of frames 15, 18, 41, and 43 and applicable related investigative and corrective actions. The existing AD also provides an optional action that would extend the repetitive inspection interval. This proposed AD would add a high frequency eddy current inspection for corrosion of the outer frame flanges and door hinge bosses of frames 15, 18, 41, and 43. This proposed AD results from a report indicating that corrosion has been detected in the outer frame flanges and door hinge bosses during scheduled maintenance. We are proposing this AD to prevent reduced structural integrity of the airplane.

We propose to adopt a new Airworthiness Directive (AD) for the products listed above. This proposed 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:

The Federal Aviation Administration (FAA) and the National Park Service (NPS), in accordance with the National Parks Air Tour Management Act of 2000, announce the next meeting of the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). This notification provides the date, format, and agenda for the meeting and provides additional information to the Federal Register notice published on February 3, 2009 (Vol. 74, No. 21, Page 5969) by providing the call in number for the public to access the telcon. Dates and Location: The NPOAG ARC will hold a meeting on February 25th, 2009. The meeting will be conducted as a telephone conference call. The meeting will be held from 9 a.m. to 12 p.m. Pacific Standard Time on February 25th. This NPOAG meeting will be open to the public. Interested persons may listen in on the conference call (see Public Participation at the Meeting)

We are adopting a new airworthiness directive (AD) for certain Learjet Model 55, 55B, and 55C airplanes. This AD requires inspecting the installation of the forward light assembly in the aft lavatory to determine the location of the terminal connector; inspecting for damage of the light assembly terminals, wires, and oxygen lines; inspecting to determine if the cable nipple is installed over the light assembly terminal; and doing corrective actions if necessary. This AD also requires installing a clamp to the forward side of the frame to maintain a positive distance between the light assembly and oxygen line. This AD results from a report of a cabin fire in the left-hand upper cabin fuselage above the aft cabin window at frame 23. We are issuing this AD to detect and correct improper installation of the lavatory light assembly, which could result in contact between the electrical terminals of the light assembly and an adjacent oxygen supply line, and consequent short circuit or fire hazard.

The FAA is adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 401, 401A, 401B, 402, 402A, and 402B airplanes. This AD requires an inspection of the auxiliary wing spar near the location where the main landing gear trunnion is mounted for cracks; immediate replacement if cracks of 0.5 inch or more are found; repetitive inspections with replacement at a later time as long as cracks of less than 0.5 inch are found; and a report to the FAA and Cessna if any cracks are found. This AD results from several reports of fatigue cracking on the affected airplanes in the auxiliary wing spar. We are issuing this AD to detect and correct such cracks, which, if not corrected, could result in failure of the wing auxiliary spar web and cause landing gear collapse during normal landing. This could lead to loss of control and passenger injury.

This action amends Class E airspace at Tulsa, OK. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at William R. Pogue Municipal Airport, Sand Springs, OK. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at William R. Pogue Municipal Airport.

This action removes Class E airspace at Rockport, TX. This airspace has been incorporated into the Corpus Christi, TX, Class E airspace area under a separate rulemaking action to ensure the safety of aircraft and efficient use of airspace.
