The International Helicopter Safety Team (IHST) recently reorganized a number of resource documents to help helicopter pilots maintain currency. One guide, which is focused on autorotations, evolved after the FAA discovered a need to raise awareness of the risks inherent in conducting these maneuvers in the training environment, particularly the 180-degree autorotation. The guide was also designed to recommend procedures to help reduce those risks.
Airbus Brazilian subsidiary Helibras recently held its second “Operational Safety Days,” filling São Paulo’s Anhembi Morumbi University auditorium to its 300-seat capacity. “We’ll need a bigger place next year,” Helibras safety manager Antonio Modesto told AIN, describing the helicopter safety event as “the realization of a personal dream” with full company support.
The National Transportation Safety Board (NTSB) believes methane gas expelled from an offshore oil rig in the Gulf of Mexico caused the partial power failure on a Bell 206-L3 helicopter departing the MP61A platform on March 24, 2011. The pilot experienced the power failure at about 4:55 p.m., shortly after liftoff. The NTSB attributed the power loss to an engine compressor stall after it ingested methane gas during takeoff.
Preliminary Report: Hard Landing Damages AStar
Airbus Helicopters will lead the design of a compound rotorcraft demonstrator dubbed “LifeRCraft” (Low Impact Fast & Efficient RotorCraft) as part of Europe’s Clean Sky 2 Joint Technology Initiative, which was formally launched last week in Brussels. Preliminary studies, architecture and specification activity will start this year, with development and testing of components and subsystems envisioned in the 2016-2018 timeframe. Flight evaluations could start in early 2019.
The AgustaWestland AW609 civil tiltrotor passed another milestone on the road to certification by completing autorotation testing at AgustaWestland’s Arlington, Texas facility over the course of 10 flight hours in March and early April. Test aircraft Number 1 made more than 70 power-off conversions from airplane to helicopter mode.
The AgustaWestland AW609 civil tiltrotor achieved another milestone on the road to certification, recently completing autorotation testing at the company’s facility in Arlington, Texas. Over the course of 10 flight hours in March and early this month, an AW609 test aircraft made more than 70 power-off conversions from airplane to helicopter mode.
The EASA is considering increasing the time in which a pilot is expected to respond to engine failure in a single-engine helicopter, to align certification standards with real-world human performance. The new standard, if adopted, would require helicopters to be designed so that the pilot has more time to respond before a decay in rotor rpm takes the machine into hazardous dynamic territory. A study by Dutch aerospace research center NLR shows that this would add weight and cost.
The pilot of a Eurocopter EC130 helicopter said she was on day-visual approach to Nevada’s Boulder City Municipal Airport when the engine flamed out on a post-maintenance flight. In the January 1 incident, the aircraft was still 200 feet in the air when a “low fuel pressure” indicator light illuminated followed by the engine shutting down. The pilot attempted an autorotation but didn’t have enough forward speed to complete the maneuver. The tailboom hit the ground first followed by the main skids, which quickly separated from the airframe, resulting in substantial damage.
The new Sikorsky S-76D medium twin recently performed high-altitude takeoff and landing tests at Colorado’s Lake County Airport, the helicopter manufacturer announced last week. The trials, which took place at almost 10,000 feet msl, were part of a so-called envelope-expansion program.
