TAIL ROTOR BLADE ASSEMBLY, INSPECTION OF 

Revision "C" to this bulletin re-organises the affected blade list to include the blade 

part numbers. No additional blade serial numbers were added to the affected blade 

list. The affected blade part numbers listed in this ASB reflect the last dash number of 

the blades as they left Rotor Blade, Inc. (RBI). Upgrade/modification of the blades in 

the field since then may have altered the blade last dash number. Verify part number 

on blade and in the blade component history card records. The model 

222/222B/222U/230/430 tail rotor blades are all built in consecutive serial numbers 

regardless of the blade last dash number.

Mr. Jack Denham 

Executive Director of Product Support 

Bell Helicopter Textron 

Rotor Blades, Inc. (RBI) has received reports of three incidents in which weights were slung from tail 

rotor blades during flight significant causing vibration. The failures reported occurred ranging from 

400 flight hours since repair to as short as 12 minutes. We have determined that this may affect most 

Bell models. To ensure safety and to expedite re-inspection required, we advise and ask you 

distribute to fleet on a most urgent basis. 

Investigation indicates that tip weight screws may be missing the adhesive applied during the weight 

and balance process on these blades. The blades in question were all processed by one former RBI 

technician . 

RBI has initiated customer contact and inspection of blades to reduce customer impact. Additionally, 

we are working with our local FAA representative to ensure regulations are met. I ask Bell support 

and assistance to ensure DOT and OEM requirements are met for release. 

RBI is capable of carrying out inspection to existing requirements. Balance weight screws must be 

accessed and verified for correct installation. This must be carried out by a Bell approved Rotor Blade 

Repair Facility. 

BEFORE THE NEXT FLIGHT, ALL OPERATORS SHOULD INSPECT THEIR TAIL ROTOR BLADES USING 

THE ATTACHED LIST TO DETERMINE WHETHER THEIR BLADES ARE AFFECTED. ALL AFFECTED 

BLADES SHOULD BE REMOVED FROM SERVICE IMMEDIATELY AND RETURNED TO AN RBI FACILITY 

FOR EXAMINATION AND REPAIR. 

The list attached includes all blades RBI has determined re-inspection is required on .
