  • Page 194 MODEL R44 SAFETY TIPS SAFETY NOTICES The following Safety Notices have been issued by Robinson Helicopter Company as a result of various accidents and incidents. Studying the mistakes made by other pilots will help you avoid making the same errors. Safety Notices are available on the RHC website: www.robinsonheli.com.
  • Page 212 Safety Notice SN-32 Issued: March 1998 Revised: May 2013 HIGH WINDS OR TURBULENCE A pilot’s improper application of control inputs in response to high winds or turbulence can increase the likelihood of a mast bumping accident. The following procedures are recommended: 1.
  • Page 213 Issued: March 1998 Revised: July 2013 DRIVE BELT SLACK R22 and R44 drive belts must have the proper slack prior to engine start. Belts which are too loose may jump out of their sheave grooves during engine start while clutch is engaging.
  • Page 214 INTENTIONALLY BLANK...
  • Page 220 Some pilots mistakenly attribute this yaw to loss of tail rotor effectiveness (LTE), implying that the tail rotor stalled or was unable to provide adequate thrust. Tail rotors on Robinson helicopters are designed to have more authority than many other helicopters and are unlikely to experience LTE.
  • Page 221 Safety Notice SN-43 Issued: January 2015 USE EXTRA CAUTION DURING POST-MAINTENANCE FLIGHTS A number of fatal accidents have occurred during flights immediately following maintenance. In several cases, the cause was incorrect or incomplete reassembly of the helicopter, and the error would have been detectable during a careful preflight inspection.
