**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are superseding Airworthiness Directive (AD) 2010–06– 04, for certain Airbus Model A300 B2– 1C, B2–203, B2K–3C, B4–103, B4–203, B4–2C airplanes; Model A310 series airplanes; Model A300 B4–600 series airplanes; and Model A300 B4–600R series airplanes. AD 2010–06–04 required repetitive inspections to detect cracks of the pylon side panels (upper section) at rib 8; and corrective actions if necessary. This new AD continues to require repetitive inspections for cracking of the pylons 1 and 2 side panels (upper section) at rib 8 with reduced compliance times, and corrective actions if necessary. This AD also requires repetitive post-repair and post-modification inspections and repair if necessary. This AD also removes certain airplanes having a
certain modification from the applicability. This AD was prompted by reports of cracks found on pylon side panels at rib 8 and a fleet survey and updated fatigue and damage tolerance analyses. We are issuing this AD to detect and correct cracking of pylon side panels (upper section) at rib 8, which
could lead to reduced structural integrity of the pylon primary structure,
which could cause detachment of the engine from the fuselage.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2010–06–04,


## 81169 Federal Register / Vol. 80, No. 249 / Tuesday, December 29, 2015 / Rules and Regulations

Amendment 39–16228 ((75 FR 11428, March 11, 2010); corrected May 4, 2010 (75 FR 23572)). AD 2010–06–04 applied to certain Airbus Model A300 B2–1C, B2–203, B2K–3C, B4–103, B4–203, B4– 2C airplanes; Model A310 series airplanes; Model A300 B4–600 series airplanes; and Model A300 B4–600R series airplanes. The NPRM published
in the Federal Register on September 22, 2014 (79 FR 56526).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2013–0136R1, dated July 30, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct
an unsafe condition on certain Airbus Model A300 B2–1C, B2–203, B2K–3C, B4–103, B4–203, B4–2C airplanes; Model A310 series airplanes; Model A300 B4–600 series airplanes; and Model A300 B4–600R series airplanes.
The MCAI states:

Cracks were found on pylon side panels (upper section) at rib 8 on Airbus A300, A310 and A300–600 aeroplanes equipped with General Electric engines. Investigation of these findings indicated that this problem was likely to also affect aeroplanes of this type design with other engine installations.

This condition, if not detected and corrected, could lead to reduced strength of the pylon primary structure, possiblyresulting in pylon structural failure and inflight loss of an engine.

Prompted by these findings, EASA issued AD 2008–0181 [http://www.regulations.gov/ #!documentDetail;D=FAA-2009-0789-0002] [which corresponds to FAA AD 2010–06–04, Amendment 39–16228 ((75 FR 11428, March 11, 2010); corrected May 4, 2010 (75 FR 23572))] to require repetitive detailed visual inspections [of the pylon side panels (upper section) at rib 8] and, depending on aeroplane configuration and/or findings, the accomplishment of applicable corrective action(s).

Since that [EASA] AD was issued, a fleet survey and updated Fatigue and Damage Tolerance analyses have been performed in
order to substantiate the second A300–600 Extended Service Goal (ESG2) exercise. The results of these analyses have shown that the risk for these aeroplanes is higher than initially determined and consequently, the
threshold and interval must be reduced to allow timely detection of these cracks and the accomplishment of applicable correction action(s).

EASA issued AD 2013–0136 [http:// ad.easa.europa.eu/ad/2013-0136R1 ] which retained the requirements of EASA AD 2008– 0181, which was superseded, and required the inspections to be accomplished within
reduced thresholds and intervals.

After publication of EASA AD 2013–0136, it appeared that Airbus Mod 03599 had no influence on the aeroplane configuration affected by this AD. At the same time Airbus Service Bulletin (SB) A30–54–6015 Revision 3 was not integrally taken into account as this revision no longer identifies configuration 3 aeroplanes.

For the reasons described above, EASA [AD] 2013–0136 is revised to exclude Airbus Mod 03599 from the applicability and to delete the reference to the configuration 3 for A300–600 aeroplanes.



### Corrective actions include doing a repair. This AD also provides an optional modification (installing a doubler), which would terminate the repetitive inspections. Required actions also include repetitive post-repair and post-modification inspections and repair if necessary. You may examine
the MCAI in the AD docket on the

Internet at http://www.regulations.gov/ #!documentDetail;D=FAA-2014-0648-

.
Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM (79 FR 56526, September 22, 2014) and the FAA’s

response. Request To Revise Method Used To Determine Compliance Times

United Parcel Service (UPS) requested that we revise the proposed compliance times to be less complex. UPS stated that the proposed compliance times contain a method known as ‘‘Average Flight Time’’ (AFT) which results in a variable flight hour limit and adds unnecessary complexity to the threshold table and subsequent inspection actions. UPS added that use of the AFT method, along with a lack of standard procedures for implementing the AFT method would create uncertainty for operators and inspectors trying to determine the correct compliance time. UPS stated that in review of prior FAA ADs, including AD 98–18–02, Amendment 39–10718 (63 FR 45689, August 27, 1998), that the FAA does not concur with the AFT compliance time methodology as ‘‘. . . such adjustments may not address the unsafe condition in a timely manner’’ and ‘‘. . . they (AFT compliance times) do not fit into the AD tracking process for operators or for Principle Maintenance Inspectors (PMIs) attempting to ascertain compliance with ADs.’’

UPS compiled a table of fixed compliance times that it suggested would be simpler to use instead of the proposed AFT-based compliance times.

We disagree with the commenter’s request to revise the compliance times in this AD. The compliance times, as proposed, use fixed flight-cycle and flight-hour compliance times. For only Model A310 series airplanes, the compliance times depend on whether airplanes are short range or long range airplanes. We acknowledge that this causes additional complexity in tracking and forecasting airplane utilization; however, the inspection schedule was created by Airbus to offer operators the greatest flexibility. Operators may elect to inspect within the range that complies with both the long range and short range utilization in order to reduce the complexity. We have not changed this AD in this regard.

Regarding AD 98–18–02, Amendment 39–10718 (63 FR 45689, August 27, 1998), at the time the FAA issued AD 98–18–02, the required actions in
Airbus Industrie Service Bulletin A300– 57–6027, Revision 2, dated September 13, 1994, contained inspection
thresholds and intervals based on airplane flight cycles, and provided instructions for adjusting the flight cycle threshold and interval using each individual airplane’s AFT utilization. The FAA did not agree with the AFT
method because it could result in a different inspection threshold and interval for each individual airplane, and the FAA did not agree with adjusting a flight cycle based threshold and interval using the average flight time utilization without also having a related flight hour based threshold and
interval.

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (79 FR 56526, September 22, 2014) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 56526, September 22, 2014).

### 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 determined that this AD will not have federalism implications under
Executive Order 13132. This AD will 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 this AD:

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; 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.

### Airworthiness Directives; Airbus **Airplanes**

**AGENCY**

### : Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for all Airbus Model A330–200, A330–200 Freighter, and A330–300 series airplanes; and Airbus Model A340–200, A340–300, A340–500, and A340–600 series airplanes. This AD was prompted by a report that, during a production flight test, the ram air turbine (RAT) did not pressurize the green hydraulic system. For certain airplanes, this AD requires identification of the part number, serial number, and standard of the RAT pump, RAT module, RAT actuator, and RAT lower gearbox assembly; replacement of the balance weight screw, modification of the actuator coil spring, modification of the actuator, an inspection of the anti-stall
valve for correct installation in the RAT pump housing; and corrective actions if necessary. For certain other airplanes, this AD requires re-identification or replacement of the RAT module. We are issuing this AD to prevent loss of the impeller function and RAT pump pressurization capability, which, if preceded by a total engine flame-out,
could result in the loss of control of the airplane.

**DATES** 

### : This AD becomes effective February 2, 2016.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 2, 2016.
