A new Special Airworthiness Information Bulletin (SAIB) alerts owners and operators of the availability of a fuel tank bladder retrofit program for enhanced safety on Robinson Helicopter Company (Robinson) Model R44 and R44 II helicopters.

Robinson Helicopter Company has issued Service Bulletin SB-78B, Revision B, dated September 28, 2012, which specifies that R44 helicopters with aluminum fuel tanks be retrofitted to add bladder-type tanks and associated fuel system components. In addition to a factory retrofit program, a field kit is also available. The new bladder tank and fuel system components will improve the R44 fuel system’s resistance to a post-accident fuel leak and possible fire.

The FAA recommends that owners/operators of Robinson helicopters incorporate SB-78B, Revision B, dated September 28, 2012.
