TO: All Owners/Operators of Bell 222U Helicopters SUBJECT: REVISION "C" TO ALERT SERVICE BULLETIN 222U-07-77:
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.

The model 222/222B/222U/230/430 tail rotor blades are all built in consecutive serial numbers regardless of the blade last dash number.
AN APPROPRIATE ENTRY SHOULD BE MADE IN THE AIRCRAFT LOGBOOK UPON ACCOMPLISHMENT

September 11, 2007 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.
Troy Penny Director of Operations Rotor Blades Inc.
