FAA Finalized Fatigue Damage Rule

George’s Point of View

Design approval holders must now set a time- or cycle-based limit after which structural damage inspections must take place. The rule specifically addresses widespread fatigue damage (WFD) with the intent of “providing for the establishment of safe operational limits and the maintenance actions necessary to preclude WFD prior to reaching those limits.

The FAA Statement is below:

Press Release – FAA Adopts “Comprehensive Solution” to Widespread Fatigue on Aging Aircraft

WASHINGTON, D.C. – In a continuing effort to address aging aircraft issues, the Federal Aviation Administration (FAA) has finalized a rule designed to protect most of today’s commercial planes and those designed in the future from structural damage as they age.

The new rule seeks to prevent “widespread fatigue damage” (WFD) by requiring aircraft manufacturers and certification applicants to establish a number of flight cycles or hours a plane can operate and be free from WFD without additional inspections for fatigue. Manufacturers have between 18 and 60 months to comply depending on the particular aircraft type.

Once manufacturers establish these limits, operators of affected aircraft must incorporate them into their maintenance programs within 30 to 72 months, depending on the model of aircraft. After the limit is in the maintenance program, operators cannot fly the aircraft beyond that point unless the FAA approves an extension of the limit.

“Safety is our highest priority. This rule provides a comprehensive approach to the problem of widespread fatigue in aging aircraft,” said U.S. Transportation Secretary Ray LaHood. “Requiring carriers to regularly inspect their aircraft for possible fatigue is essential to ensuring the highest levels of safety.”

“We’ve addressed the problem of aging aircraft with numerous targeted regulations and 100 airworthiness directives over the years,” said FAA Administrator Randy Babbitt. “This rule is a comprehensive solution to ensure the structural safety of today’s airliners and the airplanes of tomorrow.”

An airplane’s metallic structures are stressed and can develop cracks when they experience repeated loads such as the pressurization and depressurization that happens on every flight. While airlines regularly inspect aircraft for cracks exceeding a certain size, WFD involves aircraft developing numerous tiny cracks, none of which would have raised concerns individually but which together run the risk of joining up and impairing the structural integrity of the plane.

The new regulation applies to airliners with a takeoff weight of 75,000 lbs. and heavier. It also applies to all transport designs certificated in the future.

The affected models, totaling 4,198 U.S.-registered airplanes, are listed in the rule.
The FAA is working closely with the European Aviation Safety Agency (EASA) and other national authorities to harmonize this rule with their regulations as much as possible. EASA is now developing rulemaking to address WFD, and the FAA participates in that process.

    Boeing PR: NewGen Tanker Win Would Bring 230 Jobs, $10 Million to Oklahoma

    OKLAHOMA CITY, Nov. 12, 2010 — The Boeing Company [NYSE: BA] today announced that Oklahoma will benefit from an estimated 230 total jobs and generate an estimated $10 million in annual economic impact if the NewGen Tanker is selected as the U.S. Air Force’s next aerial refueling aircraft.

    Boeing submitted its proposal July 9 to replace 179 of the Air Force’s 400 Eisenhower-era KC-135 aircraft. The Air Force is expected to award a contract in the next few months.

    "We welcome the high-paying, skilled jobs that the Boeing tanker project will support," said Oklahoma Gov. Brad Henry. "Oklahomans will be very proud to contribute to the mission of our country’s brave military men and women, who need just the kind of state-of-the-art, American-made tanker that Boeing has proposed."

    "Oklahoma’s aerospace workers will play an integral role on Boeing’s tanker team," said Mark DeVoss, Supplier Management director, Boeing Tanker Programs. "Along with the rest of the United States Tanker Team, our suppliers in Oklahoma will be focused on building a NewGen Tanker that best meets America’s military needs at the greatest value to American taxpayers."

    Oklahoma manufacturers ready to produce critical components on the NewGen Tanker include:

    • Boeing, Oklahoma City
    • Cinch Connectors, Vinita
    • Limco Manufacturing, Tulsa
    • Precise Machining & Manufacturing, Tulsa.

    Currently, Boeing has 964 employees in Oklahoma and works with nearly 247 suppliers/vendors, delivering a total $531 million in annual economic impact.

    The NewGen Tanker is a widebody, multi-mission aircraft based on the proven Boeing 767 commercial airplane and updated with the latest and most advanced technology. Capable of fulfilling the Air Force’s needs for transport of fuel, cargo, passengers and patients, the combat-ready NewGen Tanker will meet or exceed the 372 mandatory requirements described in the service’s final KC-X Request for Proposal released Feb. 24.

    The NewGen Tanker will be made with a low-risk approach to manufacturing that relies on existing Boeing facilities in Washington state and Kansas as well as U.S. suppliers throughout the nation, with decades of experience delivering dependable military tanker and derivative aircraft. Nationwide, the NewGen Tanker program will support approximately 50,000 total U.S. jobs with Boeing and more than 800 suppliers in more than 40 states.

    The Boeing NewGen Tanker also will be more cost-effective to own and operate than a larger, heavier tanker. It will save American taxpayers more than $10 billion in fuel costs over its 40-year service life because it burns 24 percent less fuel than the competitor’s airplane.

    Boeing has been designing, building, modifying and supporting tankers for decades. These include the KC-135 that will be replaced in the KC-X competition, and the KC-10 fleet. The company also has delivered four KC-767Js to the Japan Air Self-Defense Force and is on contract to deliver four KC-767As to the Italian Air Force.

    New FAA System Improves Air Safety at Juneau

    New FAA System Improves Air Safety at Juneau

    ANCHORAGE – A new surveillance technology called the Wide-Area Multilateration System (WAM) is now allowing air traffic controllers to track aircraft along the difficult approach to Juneau – a mountainous area where radar coverage isn’t possible.

    “This technology will allow more aircraft to fly into Juneau and it will give air traffic controllers the tools they need to safely and efficiently handle these flights,” said FAA Administrator Randy Babbitt.

    Air traffic controllers can now see aircraft approaching Juneau, something that wasn’t possible before WAM because of the rugged terrain surrounding the city. The mountains make radar coverage impossible since radar signals cannot pass through solid objects. Without radar coverage, controllers had to separate aircraft approaching Juneau by large distances in order to provide the appropriate safety margins. Air traffic controllers are now able to safely decrease the separation between them to five nautical miles.

    WAM is comprised of a network of small sensors deployed around Juneau. The sensors send out signals that are received and sent back by aircraft transponders. No other aircraft equipment is required. The system triangulates the returning signals to determine the precise location of each aircraft. Controllers are able to see those aircraft on their screens as if they were radar targets.

    WAM is being used in the near term while the agency rolls out Automatic Dependent Surveillance – Broadcast (ADS-B), the satellite-based surveillance system that will be deployed nationwide in 2013. WAM will then serve as a backup to ADS-B in the event of a GPS outage and provide an additional source of traffic broadcast to properly equipped aircraft. A WAM system is also operating in Colorado.

    FAA Proposes $1.45 Million Civil Penalty against Northwest Airlines

    WASHINGTON, D.C. – The Federal Aviation Administration (FAA) has proposed a $1.45 million civil penalty against Northwest Airlines for operating a number of its Boeing 757 aircraft without proper windshield wiring inspections.

    A 1990 FAA airworthiness directive on Boeing 757s required inspections for the presence of undersized wires in the heating system for both the captain’s and first officer’s windows, and replacement if needed. Left uncorrected, the problem could cause overheating, smoking and possibly a fire.

    Northwest wrote maintenance instructions for its mechanics in April 1990 that omitted the required inspection of the wires under the first officer’s window. As a result, 32 of the carrier’s 757s flew more than 90,000 passenger flights between December 1, 2005 and May 27, 2008, while not in compliance with the airworthiness directive.

    “Safety is the number one priority for the Department of Transportation,” said Transportation Secretary Ray LaHood. “The FAA has airworthiness directives for a reason and carriers cannot pick and choose when they want to comply.”

    On May 28, 2008, Northwest discovered it had not performed the proper inspections and revised its maintenance instructions. However, the instructions did not require the work be performed before further flight, but at the next planned overnight layover. As a result, 29 of the 32 aircraft flew 42 passenger-carrying flights while they were still out of compliance with the airworthiness directive.

    “When an air carrier realizes that an airworthiness directive is not being followed the problem must be corrected immediately,” said FAA Administrator Randy Babbitt. “Safety cannot wait for the next scheduled maintenance.”

    The airline has 30 days from the receipt of the FAA’s civil penalty letter to respond to the agency.
