EASA SIB SW-12-12
Sikorsky (formerly Schweizer, Hughes) 269C and 269C-1 Helicopters - Engine Failure Simulation
Summary
The Special Airworthiness Information Bulletin (SAIB) SW-12-12 provides guidance for owners and operators of Sikorsky (formerly Schweizer, Hughes) 269C and 269C-1 helicopters regarding engine failure simulation. It addresses updated instructions in the approved Pilot Flight Manual to prevent engine stoppage caused by rapid throttle reductions during practice autorotations in helicopters with air-aspirated reciprocating engines.
What Changed
The SAIB introduces updated Pilot Flight Manual revision #18, approved on June 28, 2011, which clarifies instructions and warnings against rapid throttle reductions to full idle during practice autorotations. It also adds a 'Post Flight Requirements' section detailing pilot responsibilities after flight, including passenger briefing, proper shutdown procedures, aircraft servicing, maintenance notification, and securing the aircraft.
Why It Matters
This information is important for aviation professionals because it helps reduce the risk of engine shutdown accidents during training maneuvers, enhancing flight safety for operators of Schweizer 269C and 269C-1 helicopters. Compliance with the updated manual supports adherence to FAA practical test standards and promotes proper aircraft handling and maintenance communication.
What To Do
Pilots and operators should follow the updated Pilot Flight Manual revision #18 for Schweizer 269C and 269C-1 helicopters, avoiding rapid throttle chops to full idle during autorotation practice. They must also complete the new post-flight procedures as outlined in the manual. There is no mandatory compliance deadline, but adherence to these recommendations is strongly advised.
