Fatigue

June 3, 2014 - 5:10am

EASA has certified a redesigned vertical bevel gear shaft for the Airbus Helicopters EC225, which was grounded for nine months in 2012 and 2013 after a series of in-flight failures. Manufacture of the redesigned gear shaft is under way for production aircraft and retrofits, with first installations (for both applications) planned for this year’s second half.

The new design provides corrosion resistance, compensates for residual stress and eliminates stress hot spots, eliminating all three factors that, combined, caused two unexpected vertical shaft failures.

The National Transportation Safety Board on May 13 released the findings of its Special Investigation Report on the safety of agricultural aircraft operations, which can involve flying as low as 10 feet above the ground. That kind of flying presents risks from ground-based obstacles with scant room for error.

Argus added an aviation fatigue meter, a “proprietary algorithm and system that translates raw user data into actionable fatigue information” developed by Pulsar Informatics, into its Prism Armor safety management system (SMS) software. Argus said that users will be able to monitor and analyze crew fatigue more accurately and make more informed decisions.

The Greater Washington Business Aviation Association’s (GWBAA) 2014 safety standdown takes place May 1 at the NTSB training center in Ashburn, Va. The keynote speaker will be Greg Feith, a former member of the NTSB and an aviation safety and security expert. Planned topics include the ISBAO program, hangar safety systems and sleep apnea/fatigue.

As the 25th annual NBAA’s Schedulers & Dispatchers Conference kicks off in New Orleans on Tuesday, organizers anticipate setting a new record for exhibitors at approximately 500. This would eclipse the 425 airports, FBOs, fuel suppliers and other companies that displayed their services at last year’s event, which was held in San Antonio.

The Transportation Safety Board of Canada (TSB) says in a December 2013 report that a manufacturing defect by Bell Helicopter caused eight feet of a 206L LongRanger’s main rotor blades to separate in flight on Nov. 2, 2011. The pilot and two passengers were killed when the aircraft, operated by Sunrise Helicopters, subsequently crashed shortly after takeoff from Kapuskasing in Ontario.

The Flight Operations Risk Assessment System (Foras) was created to quantitatively assess aviation risk factors with more than simple accident rates. As highlighted in the Flight Safety Foundation’s November 2013 AeroSafety World publication, the system breaks down risks into ever smaller elements to simplify analysis.

The Jan. 4, 2014 implementation date for new Part 117 regulations on fatigue applies only to scheduled air carriers, but many observers believe elements of the new law will eventually work their way to business aviation.

The European Aviation Safety Agency (EASA) issued an airworthiness directive requiring inspections and possibly modifications to the Airbus A380, stating that cracks discovered during fatigue testing could “reduce the structural integrity of the wing.”

Among the exhibitors making their debuts at NBAA’s annual showcase is Pulsar Informatics (Booth No. C12047), which is demonstrating its new crew fatigue evaluation web application: the Aviation Fatigue Meter. According to the Philadelphia-based company, the app can be used for every kind of business aviation operation, no matter the scale or complexity, and it is described as an “easy way for people to see how any particular schedule is impacted by human fatigue factors.”
