ROBINSON HELICOPTER COMPANY MODEL R44 DAILY OR PREFLIGHT CHECKS Visit www.robinsonheli.com to verify this checklist is current. GENERAL PROCEDURES • Remove ground handling wheels and all covers and tie-downs. • Remove even small accumulations of frost, ice, or snow, especially from rotor blades. • Check maintenance records to verify aircraft is airworthy. An 8-foot step ladder is recommended for preflight inspection of the main rotor; however, main rotor hub may be reached by first opening right rear seat and stepping on seat support and then stepping on deck below the aux fuel tank. • Check general condition of aircraft and verify no visible damage, fluid leakage, or abnormal wear. • Verify no fretting at rivets and seams where parts are joined together. Fretting of aluminum parts produces a fine black powder while fretting of steel parts produces a reddish-brown or black residue. • Verify Telatemps show no temperature increase that cannot be attributed to a change in operating conditions (mechanics draw a reference line to the right of the highest temperature square which has darkened in operation). • Verify torque stripes on critical fasteners are not broken or missing.
