Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
We are superseding airworthiness directive (AD) 2006-18-14 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 650-15 and Tay 651-54 turbofan engines. AD 2006-18-14 required calculating and re- establishing the cyclic life of stage 1 high-pressure turbine (HPT) disks, part number (P/N) JR32013 and P/N JR33838, and stage 1 low- pressure turbine (LPT) disk, P/N JR32318A. In addition, this AD requires re-calculating the cyclic life, and would impose a reduced cyclic life of stage 1 HPT disk, P/N JR32013. This AD was prompted by RRD review of the cyclic life limit of parts affected by AD 2006-18-14 and the RRD conclusion that the stage 1 HPT disk, P/N JR32013, requires further cyclic life limit reduction. We are issuing this AD to prevent failure of stage 1 HPT disks, P/N JR32013 and P/N JR33838, and stage 1 LPT disk, P/N JR32318A, uncontained disk release and damage to the airplane.
Airworthiness Directives; All Hot Air Balloons
We are adopting a new airworthiness directive (AD) for all hot air balloons to determine if BAL[Oacute]NY KUB[Iacute][Ccaron]EK spol. s r.o. Model Kub[iacute][ccaron]ek burners equipped with fuel hoses made of ``EGEFLEX'' material are installed. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as propane leaks found on burners equipped with fuel hoses made of EGEFLEX material. We are issuing this AD to require actions to address the unsafe condition on these products.
