BELL 47G-2A
THE PLT WAS TAKING 2 PASSENGERS ON A HELICOPTER RIDE AT A FAIR. IMMEDIATELY AFTER LIFT-OFF, HE ENCOUNTERED A SITUATION WHERE HE WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL, SO HE REDUCED POWER & LANDED. BEFORE COMING TO REST, THE TAIL OF THE HELICOPTER STRUCK A VAN. AN INVESTIGATION REVEALED THAT THE INNER BEARING (PN 47-620-605-001) OF THE TAIL ROTOR DRIVE HAD FAILED, THEN THE DRIVE SHAFT FAILED. AD 81-04-03, AMENDMENT 39-4029 BECAME EFFECTIVE ON 2/2/81 TO REPLACE THE BEARING IN THE NEXT 600 HRS OF SERVICE. HOWEVER, THE HELICOPTER HAD ACCUMULATED LESS THAN 600 HRS SINCE THAT DATE.
