Airworthiness Directive 2013-16-23
one-timeAirworthiness Directives; Rolls-Royce plc Turbofan Engines
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-524B-02; -524B2-19; -524B3-02; -524B4-02; - 524C2-19; -524D4-19; -524D4-B-19; -524D4-39; -535C-37; -535E4-37; - 535E4-B-37, and -535E4-B-75 turbofan engines, and all RB211-524G2-19; - 524G3-19; -524H2-19; and -524H-36 turbofan engines. This AD requires a one-time inspection of the front combustion liner (FCL) metering panel to determine if it is made from N75 material and, if so, replacing it with an FCL made from C263 material. This AD was prompted by the discovery of a cracked and distorted FCL metering panel, which was made from N75 material. We are issuing this AD to prevent hot gases from burning through the engine casing, which could result in an under-cowl fire and damage to the airplane.
Which aircraft AD 2013-16-23 applies to
Applies to: (1) all RB211-524G2-19, -524G3-19, -524H2-19, and -524H-36 engines; (2) RB211-524B-02, -524B2-19, -524B3-02, -524B4-02, -524C2-19, -524D4-19, -524D4-B-19, and -524D4-39 engines only if RR Service Bulletin (SB) No. RB.211-72-7221, dated December 7, 1984, has been incorporated; (3) RB211-535C-37, -535E4-37, -535E4-B-37, and -535E4-B-75 engines, except those that have incorporated RR SB No. RB.211-72-C230, Revision 1 (dated November 22, 2012), or Initial Issue (dated November 16, 1999). Does not apply to any of the foregoing engines if a front combustion liner (FCL) metering panel delivered from RR after April 23, 2007, is installed.
Whether AD 2013-16-23 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
