THE PILOT PURCHASED THE HELICOPTER WITH AN UNDOCUMENTED MODIFICATION DESIGNED TO RESTRAIN THE COLLECTIVE. REPORTEDLY, HERECEIVED NO GUIDANCE REGARDING THE USE OF THE COLLECTIVE HOLD-DOWN DEVICE. ACCORDING TO THE AIRCRAFT MANUFACTURER THERE EXISTED NO ENSTROM APPROVED COLLECTIVE HOLD-DOWN DEVICES OTHER THAN THE INSTALLED FRICTION LOCK. AFTER ENGINE START THE PILOT USED TWO HANDS TO RELEASE THE COLLECTIVE FRICTION. THE ENSTROM F28 'BEFORE TAKEOFF' CHECKLIST WARNS PILOTS TO 'KEEP HAND ON COLLECTIVE AND MAINTAIN DOWN POSITION WHEN (COLLECTIVE) LOCK IS DISENGAGED', AFTER RELEASING THE LOCK THE PILOT SAID THE COLLECTIVE SPRUNG TO THE FULL UP POSITION. THE AIRCRAFT ROLLED TO THE LEFT ABOUT ITS LONGITUDINAL AXIS. THE PILOT STATED THAT HE RELIED ON THE MODIFICATION, A COLLECTIVE HOLD-DOWN CHAIN, TO KEEP THE COLLECTIVE SECURE.
