Summary
The Special Airworthiness Information Bulletin (SAIB) SW-13-11 issued by the FAA provides information about a fuel tank bladder retrofit program for Robinson Helicopter Company Model R44 and R44 II helicopters. This bulletin highlights the availability of a retrofit to replace aluminum fuel tanks with bladder-type tanks to enhance safety. The retrofit aims to reduce the risk of post-accident fuel leaks and potential fires in these helicopter models.

The SAIB introduces the availability of Service Bulletin SB-78B, Revision B, which specifies retrofitting Robinson R44 helicopters equipped with aluminum fuel tanks with bladder-type fuel tanks and associated fuel system components. This retrofit can be performed through a factory program or a field kit. The change improves the fuel system's resistance to leaks and fire hazards following accidents.
Why It Matters
This retrofit is important for aviation professionals because it enhances the safety of Robinson R44 and R44 II helicopters by reducing the likelihood of fuel leaks and fires after an accident. Operators and maintenance organizations benefit from improved fuel system integrity, which can mitigate damage and increase survivability. Compliance teams should be aware of this safety enhancement to advise operators accordingly.
What To Do
Owners and operators of Robinson R44 and R44 II helicopters are recommended to incorporate Service Bulletin SB-78B, Revision B, dated September 28, 2012, to retrofit their aluminum fuel tanks with bladder-type tanks.
