Summary
The FAA proposes to supersede airworthiness directive (AD) 2016-24-08 which applies to all Rolls-Royce plc (RR) RB211-Trent 875- 17, RB211-Trent 877-17, RB211-Trent 884-17, RB211-Trent 884B-17, RB211- Trent 892-17, RB211-Trent 892B-17, and RB211-Trent 895-17 model turbofan engines. AD 2016-24-08 requires repetitive inspections of the engine upper fairing and repair or replacement of any fairing that fails inspection. Since the FAA issued AD 2016-24-08, RR has developed a modification of the engine upper bifurcation nose fairing assembly that terminates the inspection requirements of this AD. This proposed AD would continue the repetitive inspections until the terminating action is performed at the next engine shop visit. The FAA is proposing this AD to address the unsafe condition on these products.
