Airworthiness Directive · Amendment 39-13200 · Rolls-Royce RB211 Series Turbofan Engines
Rolls-Royce RB211 Series Turbofan Engines
Superseded. A later AD replaced this one: AD 2005-02-05. Comply with the one in force.
This airworthiness directive (AD) is applicable to Rolls-Royce (RR) plc RB211-535E4-37, RB211-535E4-B-37, and RB211- 535E4-B-75 series turbofan engines with low pressure compressor (LPC) fan blades with the part numbers (P/Ns) listed in Table 1 of this AD. These engines are installed on, but not limited to Boeing 757 and Tupolev Tu204 series airplanes. Table 1 follows: Table 1.--Applicable LPC Fan Blade P/Ns UL16135 UL16171 UL16182 UL19643 UL20044 UL20132 UL20616 UL21345 UL22286 UL23122 UL24525 UL24528 UL24530 UL24532 UL24534 UL27992 UL28601 UL28602 UL29511 UL29556 UL30817 UL30819 UL30933 UL30935 UL33707 UL33709 UL36992 UL37090 UL37272 UL37274 UL37276 UL37278 UL38029 UL38032
This amendment adopts a new airworthiness directive (AD), that is applicable to Rolls-Royce (RR) plc RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-B-75 series turbofan engines. This amendment requires introducing an alternative technique to ultrasonically inspect installed fan blades on-wing using a surface wave ultrasonic probe. This action also adds the application of Metco 58 blade root coating as an optional terminating action. This amendment is prompted by the discovery of cracks on LPC fan blade roots during an engine overhaul. The actions specified by this AD are intended to detect cracks in LPC fan blade roots, which if not detected, could lead to uncontained multiple fan blade failure, and damage to the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
