Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2013–15– 

10 that applies to certain Rolls-Royce 

(RR) RB211 turbofan engines. AD 2013– 

15–10 requires inspecting the 

intermediate-pressure compressor (IPC) 

rotor shaft rear balance land for cracks. 

This AD eliminates a terminating action, 

expands one inspection and eliminates 

others. This proposed AD would require 

inspecting the IPC rotor shaft rear 

balance land for cracks and eliminate 

certain other inspections. We are 

proposing this AD to detect cracking on 

the IPC rotor shaft rear balance land, 

which could lead to uncontained engine 

failure and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by November 10, 

2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

On July 22, 2013, we issued AD 2013– 

15–10, Amendment 39–17526 (78 FR 

54149, September 3, 2013), for all RR 

RB211–Trent 553–61, 553A2–61, 556– 

61, 556A2–61, 556B–61, 556B2–61, 

560–61, 560A2–61, 768–60, 772–60, 

772B–60, 875–17, 877–17, 884–17, 

884B–17, 892–17, 892B–17, 895–17, 

970–84, 970B–84, 972–84, 972B–84, 

977–84, 977B–84, and 980–84 turbofan 

engines. AD 2013–15–10 requires 

inspecting the IPC rotor shaft rear 

balance land for cracks and requires onwing and in-shop inspections for the 

Trent 500, 700, 800, and 900 engines. 

AD 2013–15–10 resulted from detection 

of cracks in Trent 500, Trent 700 and 

Trent 800 IPC rotor shaft rear balance 

lands and analysis that determined 

similar cracks may exist in Trent 900 

engines. We issued AD 2013–15–10 to 

detect cracking on the IPC rotor shaft 

rear balance land, which could lead to 

uncontained engine failure and damage 

to the airplane. 

Actions Since AD 2013–15–10 Was 

Issued 

Since we issued AD 2013–15–10, 

Amendment 39–17526 (78 FR 54149, 

September 3, 2013), we determined that 

repetitive in-shop eddy current 

inspections (ECIs) are still required for 

certain RR RB211–Trent 700 and 800 

engines even after the terminating 

action in AD 2013–15–10 was 

accomplished. We also determined that 

on-wing inspections are not required for 

certain modified RR RB211–Trent 500 

and 900 engines, and that certain inshop visual inspections are not required 

for certain RR RB211–Trent 500, 700, 

800, and 900 engines. 

Relevant Service Information 

We reviewed RR Alert NonModification Service Bulletin (NMSB) 

No. RB.211–72–AG264, Revision 5, 

dated March 21, 2011; RR Alert NMSB 

No. RB.211–72–AG270, Revision 4, 

dated March 21, 2011; RR Alert NMSB 

No. RB.211–72–AG085, Revision 2, 

dated July 7, 2011; RR NMSB No. 

RB.211–72–G448, Revision 3, dated July 

7, 2011; RR Alert NMSB No. RB.211– 

72–AH059, dated December 11, 2012; 

and RR Alert NMSB No. RB.211–72– 

AH058, dated December 13, 2012. These 

service bulletins describe procedures for 

inspecting the IPC shaft rear balance 

land on RB211–Trent 500, 700, 800, and 

900 engines. 

European Aviation Safety Agency AD 

2014–0152, dated June 20, 2014, 

corrected June 25, 2014, includes 

repetitive in-shop ECI, elimination of 

repetitive on-wing inspections, and 

elimination of in-shop visual 

inspections for certain engines. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would retain the 

requirements of AD 2013–15–10 for 

inspecting the IPC rotor shaft rear 

balance land for cracks. This proposed 

AD would also require that the 

repetitive in-shop ECIs in AD 2013–15– 

10 be performed even after modifying 

certain engines. This proposed AD 

would also eliminate repetitive on-wing 

inspections for certain other engines, 

and eliminate certain in-shop visual 

inspections for all engines. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 136 engines installed 

on airplanes of U.S. registry. We also 

estimate that it would take about 14 

hours per engine to perform the 

inspections required by this AD. The 

average labor rate is $85 per hour. 

Replacement parts are estimated to cost 

about $2,271 per engine. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$470,696. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

Section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701, 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We have determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that the proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska to the extent that it justifies 

making a regulatory distinction, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.
