## 66657 Federal Register / Vol. 75, No. 209 / Friday, October 29, 2010 / Rules and Regulations

**§ 39.13 [Amended]**

■ 

### 2. The FAA amends § 39.13 by adding the following new AD:

2010–22–09 Pilatus Aircraft Ltd.: Amendment 39–16488; Docket No. FAA–2010–0849; Directorate Identifier 2010–CE–043–AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective December 3, 2010.

Affected ADs

(b) None.
Applicability

(c) This AD applies to PILATUS Aircraft Ltd. Model PC–7 airplanes, manufacturer serial numbers (MSN) 101 through 618, certificated in any category.
Subject

(d) Air Transport Association of America (ATA) Code 57: Wings.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

This Airworthiness Directive (AD) is prompted due to an occurrence when an aircraft had a partial in-flight separation of the aileron outboard bearing support.

The aileron outboard bearing supports are attached with two forward attachment bolts and two aft attachment bolts. The forward attachment bolts are approximately 3.2 mm (0.125 inch) longer than the aft attachment bolts. If the aileron outboard bearing supports have been removed, it is possible that during the reinstallation of the aileron outboard bearing supports, the attachment bolts can be installed in wrong positions. Bolts that are installed in wrong positions can damage the threads in the rear attachment anchor nuts.

Such a condition, if left uncorrected, could lead to in-flight separation of the aileron outboard bearing support, and as a consequence, the loss or limited controllability of the aircraft.

In order to correct and control the situation, this AD requires a one time inspection to verify that the bolts are installed in the correct positions and the threads of the anchor nuts are in good condition. The replacement of the attachment hardware is required if any damage on the anchor nut threads or a bolt at the wrong location is found.
Actions and Compliance

(f) Unless already done, do the following actions:

(1) Within 1 month after December 3, 2010 (the effective date of this AD), check the airplane maintenance records to determine if the left and/or right aileron outboard bearing supports have been removed at any time during the life of the airplane. Do this check following paragraph 3.A. of Pilatus Aircraft Ltd. PC–7 Service Bulletin No. 57–015, Rev. No. 1, dated July 23, 2010.

(2) If an entry is found during the airplane maintenance records check required in paragraph (f)(1) of this AD or it is unclear whether or not the left and/or right aileron outboard bearing supports have been removed at any time during the life of the airplane, before further flight, do the actions specified in paragraphs 3.A.(2) through paragraph 3.E of Pilatus Aircraft Ltd. PC–7 Service Bulletin No. 57–015, Rev. No. 1, dated July 23, 2010.

### :

Discussion

A proposal to amend 14 CFR Part 39 by superseding AD 2006–26–51, Amendment 39 14961 (72 FR 13679, March 23, 2007) for the specified ECD model helicopters was published in the Federal Register on August 11, 2010 (75 FR 48617). AD 2006–26–51 requires actions intended to address an unsafe condition on the Model MBB–BK 117 C–2 helicopters. Since we issued AD 2006–26–51, the manufacturer has modified the control lever and dynamic weights, which when installed on the helicopter will constitute terminating action for the requirements in AD 2006–
26–51.

EASA, which is the technical agent for the Member States of the European Community, has issued EASA AD No. 2007–0237, dated August 31, 2007, to correct an unsafe condition for the Model MBB–BK 117 C–2 helicopters. The MCAI AD states: ‘‘ EASA wasinformed by the manufacturer of an inflight incident in which a dynamic weight broke off the control lever subsequently leading to considerable vibrations. A visual inspection revealed that the threaded bolt of the control lever had broken off. ’’

You may obtain further information by examining the MCAI AD and service information in the AD docket.

Related Service Information

ECD has issued ECD Alert Service Bulletin MBB BK117 C–2–64A–002, Revision 2, dated August 6, 2007. The actions described in the MCAI AD are intended to correct the same unsafe condition as that identified in the service information.

FAA’s Evaluation and Unsafe Condition Determination

This helicopter has been approved by the aviation authority of the Federal Republic of Germany and is approved for operation in the United States. Pursuant to our bilateral agreement with the Federal Republic of Germany, EASA, their Technical Agent, has notified us of the unsafe condition described in the MCAI AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of this same type design.

Differences Between the AD and the MCAI AD

We refer to flight hours as hours timein-service. We do not refer to a date of October 31, 2007, for replacing the levers because the date has passed.

Comments

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were received on the proposal or the FAA’s determination of the cost to the public. We have determined that air safety and the public interest require the adoption of the rule as proposed. Cost of Compliance

We estimate that this AD will affect 41 helicopters of U.S. registry. We alsoestimate that it will take about 20 workhours per helicopter to inspect and replace the tail rotor control lever. The average labor rate is $85 per work-hour, and required parts will cost about $10,316 per helicopter. Based on these figures, we estimate the total cost of this AD to U.S. operators to be $492,656, or $12,016 per helicopter, assuming the control lever is replaced on the entire fleet. Regulatory Findings

We have 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 the 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); and

3. 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.

We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket. 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.

**AGENCY** 

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

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Analysis performed in the frame of the Extended Service Goal has led Airbus to modify the inspection programme [modification of thresholds, intervals and associated configurations] which is currently required by DGAC (Direction Ge  ́ ne

 ́ rale de l’Aviation Civile) France AD F–2005–001.

This modified inspection programme is necessary to detect and prevent damage associated with a structural fatigue phenomenon of the rear spar internal angle and the tee fitting located in the centre wing box. This condition, if not corrected, could affect the structural integrity of the centre wing box.


### * * * * *

The unsafe condition is reduced structural integrity of the wings. We are issuing this AD to require actions to correct the unsafe condition on these products.
