**Airworthiness Directives; Rolls-Royce plc Turbojet Engines** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede airworthiness directive (AD) 2013–11– 13 that applies to all Rolls-Royce plc (RR) Viper Mk. 601–22 turbojet engines. Since we issued AD 2013–11–13, RR determined that additional parts for the RR Viper Mk. 601–22 as well as additional engine models are affected. This proposed AD would add two new engine models and additional engine parts to the applicability. We are proposing this AD to prevent failure of life-limited parts, which could lead to an uncontained part release, damage to the engine, and damage to the airplane.

**DATES :**  We must receive comments on this proposed AD by December 8, 2015.

**ADDRESSES :**  You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

Discussion

On May 28, 2013, we issued AD 2013–11–13, Amendment 39–17473 (78 FR 34550, June 10, 2013) (‘‘AD 2013– 11–13’’), for all RR Viper Mk. 601–22 turbojet engines. AD 2013–11–13 requires reducing the life of certain critical parts. AD 2013–11–13 resulted from a review by RR of the lives of these parts. We issued AD 2013–11–13 to prevent failure of life-limited parts, which could lead to an uncontained part release, damage to the engine, and damage to the airplane.

Actions Since AD 2013–11–13 Was Issued

Since we issued AD 2013–11–13, RR determined that additional parts on the Viper Mk. 601–22 engine model and the Viper Mk. 521 and Mk. 522 engine models experienced the same unsafe condition. Also since we issued AD 2013–11–13, the European Aviation Safety Agency has issued AD 2015– 0127R1, dated August 14, 2015, which requires reducing the cyclic life limits of the affected parts.

Related Service Information Under 1 CFR Part 51

We reviewed RR Alert Service Bulletin (ASB) Mk. 521 Number 72– A408, Circulation A, dated January 2015; ASB Mk. 521 Number 72–A408, Circulation B, dated January 2015; ASB Mk. 522 Number 72–A413, Circulation A, dated January 2015; ASB Mk. 522 Number 72–A412, Circulation B, dated January 2015; and ASB Mk. 601–22 Number 72–A207, dated January 2015. The service information describes procedures for determining applicable part numbers and revised cyclic life limits. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the

**ADDRESSES** section of this NPRM.

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 NPRM would require accomplishing the actions specified in the service information described previously. This NPRM would add two engine models and additional affected parts to the applicability of AD 2013–
11–13. Costs of Compliance

We estimate that this proposed AD will affect about 46 engines installed on airplanes of U.S. registry. We also estimate a prorated parts cost of $66,000 per engine. We also estimate that it would take about 4 hours per engine to comply with this proposed AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $3,051,640. 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. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**RIN 2120–AA64**

**Airworthiness Directives; The Boeing Company Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede Airworthiness Directive (AD) 2008–13– 12 R1, which applies to certain The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. AD 2008–13–12 R1 currently requires various repetitive inspections for cracking of the upper frame to side frame splice of the fuselage, and other specified and corrective actions if necessary; and also provides for an optional preventive modification, which terminates the repetitive inspections. Since we issued AD 2008–13–12 R1, we have received reports of additional fatigue cracking of the upper frame to side frame splice of the fuselage, and two reports of severed frames. This proposed AD would add, for certain airplanes, an inspection to determine if the existing frame repair meets all specified requirements; for certain other airplanes, a new modification of the upper frame to side frame splice, which would terminate the repetitive inspections; and reduce certain inspection thresholds and repetitive intervals. We are proposing this AD to detect and correct fatigue cracking of the upper frame to side frame splice of the fuselage, which could result in reduced structural integrity of the frame and adjacent lap joint, causing increased loading in the fuselage skin, which will accelerate skin crack growth and result in decompression of the airplane.

**DATES :**  We must receive comments on this proposed AD by November 23,
2015.

**ADDRESSES :**  You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:
