### 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.
