The FAA has approved the Sikorsky S-92 for sea state 6 (SS6) conditions, meaning up to 20-foot waves. Thanks to additional sponson floats, the S-92’s emergency flotation system becomes the first one to be FAA certified for SS6, according to Sikorsky.

“This system was designed by the S-92 landing-gear design group, with close coordination with electrical and airframe design and structural analysis,” said Ben Del Monte, chief of propulsion/landing gear/mission systems.

The FAA is adopting an Airworthiness Directive (AD 2012-08-11) for certain Bombardier Dash 8-400 turboprop aircraft, to alleviate potential landing gear issues. The problems were identified during testing, which showed that failure of a retract-port, flexible hose on the main-landing-gear actuator could result in excessive leakage of hydraulic fluid.

Electric taxiing system

Push-back tugs and taxiing aircraft with engines powered up may well, in a few years, be seen as remnants of the past. Two exhibitors here at the Singapore Airshow are studying electric motors that would drive the aircraft’s wheels on the ground.

L-3 Communications, Fraport (owner of Frankfurt Airport and other airports), Lufthansa German Airlines, and Lufthansa Technik, with Airbus support, have teamed to jointly test a technology demonstrator, which might lead to a new way for aircraft to taxi. The group successfully tested a new method of ground operations using electric motors installed on an Airbus A320. It was the first known time electric motors were installed on the main landing gear of a commercial aircraft and used to provide all necessary aircraft ground movement.
