**AGENCY** 

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

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for Schempp-Hirth Flugzeugbau GmbH Model Discus 2cT gliders. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 small cracks which have been found on engine pylons in the area of the lower engine support that have not been detected during the standard daily inspection. This condition, if not detected and corrected, could lead to an engine pylon failure resulting in loss of control of the glider. We are issuing this AD to require actions to address the unsafe condition on these products. **DATES** 

### : This AD is effective February 15,
2012.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of February 15, 2012.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on October 21, 2011 (76 FR 65421). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

It has been reported that small cracks on engine pylons, in the area of the lower engine support, were not detected through the ‘‘standard’’ inspection required by the daily inspection instructions. The cracks were discovered only after having significantly
grown.

This condition, if not detected and corrected, could lead to an engine pylon failure and consequent damage to the aeroplane or injury to people on the ground.

For the reasons described above, this AD requires to replace the daily inspections pages of the Aircraft Flight Manual (AFM) that are describing the engine pylon inspection instructions, to inspect the affected engine pylon area in accordance with those instructions, and the replacement with a newly designed engine pylon in case of findings.


## 1625 Federal Register / Vol. 77, No. 7 / Wednesday, January 11, 2012 / Rules and Regulations

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (76 FR 65421, October 21, 2011) or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance

We estimate that this AD will affect 3 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $255, or $85 per product.

In addition, we estimate that any necessary follow-on actions would take about 8 work-hours and require parts costing $1,697, for a cost of $2,377 per product. We have no way of determining the number of products that may need these actions. 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 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. Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.
gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

The street address for the Docket Office (telephone (800) 647– 5527) is in the **ADDRESSES** 

### section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

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

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 

### 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 

### 2. The FAA amends § 39.13 by adding the following new AD:
2012–01–02 Schempp-Hirth Flugzeugbau: Amendment 39–16913; Docket No. FAA–2011–1155; Directorate Identifier 2011–CE–032–AD.
(a) Effective Date

This airworthiness directive (AD) becomes effective February 15, 2012.

(b) Affected ADs

None. (c) Applicability

This AD applies to Schempp-Hirth Flugzeugbau Discus 2cT gliders, serial numbers 1 through 35, certificated in any category, except those on which a engine pylon, part number (P/N) M03RT841, is installed. (d) Subject Air Transport Association of America (ATA) Code 54: Nacelles/Pylons.
(e) Reason

This AD was prompted by small cracks which have been found on engine pylons in the area of the lower engine support that have not been detected during the standard daily inspection. This condition, if not detected and corrected, could lead to an engine pylon failure resulting in loss of control of the glider. We are issuing this AD to require actions to address the unsafe condition on these products.
(f) Actions and Compliance

Unless already done, do the following actions:

(1) Within 30 days after the effective date of this AD, replace the daily inspection pages of the airplane flight manual following Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863–20 Revision 1, dated July 27, 2011. The actions required by this paragraph may be performed by the owner/ operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9 (a)(1)–(4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439. All other actions in this AD must be done by a properly certificated aircraft mechanic.

(2) Before further flight after doing the action in paragraph (f)(1) of this AD and repetitively thereafter at intervals not to exceed every 12 months, inspect the engine pylon for damage or cracks, following the daily inspection instructions as amended by Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863–20 Revision 1, dated July 27, 2011.

(3) If during the daily inspections in the instructions amended by Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863– 20 Revision 1, dated July 27, 2011, in paragraph (f)(1) of this AD or the inspections required in paragraph (f)(2) of this AD, any damage or crack is found on the engine pylon, before further flight, replace the engine pylon with an engine pylon part number M03RT841 following Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863– 14, dated July 18, 2006.
(g) FAA AD Differences

Note: This AD differs from the MCAI and/ or service information as follows: In addition to the daily pilot inspections of the engine pylon required by the foreign authority, the FAA also requires an initial and annual repetitive inspection by a properly certificated aircraft mechanic.

(h) Other FAA AD Provisions

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Jim Rutherford, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust,

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2011– 0224–E, dated November 24, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

During a production process review, a deviation (double side straightening) in the manufacturing process of certain Part Number (P/N) 888164 crankshafts has been detected, which may have resulted in cracks on the surface of the crankshaft. Only a few
