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 inadequate guidance for 

spin training operations. We are issuing 

this AD to require actions to address the 

unsafe condition on these products. 

DATES: This AD is effective May 8, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 8, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to all Alexander Schleicher, 

Segelflugzeugbau Model ASK 21 gliders. 

That NPRM was published in the 

Federal Register on January 15, 2014 

(79 FR 2595). That NPRM proposed to 

correct an unsafe condition for the 

specified products and was based on 

mandatory continuing airworthiness 

information (MCAI) originated by an 

aviation authority of another country. 

The MCAI states: 

ASK 21 sailplane spin characteristics can 

be controlled using tail ballast weights, 

ensuring that pilots of all weights can 

achieve the same spin results. Although the 

tail ballast weights were designed to control 

the centre of gravity of the sailplane, these 

weights significantly affect the inertia terms 

that govern the sailplane response to spin 

manoeuvres. Schleicher issued a Technical 

Note (TN) Nr. 4 in 1980 (mainly used in 

Switzerland) to provide instructions for the 

Aircraft Flight Manual (AFM) for spin 

training. These instructions did not provide 

proper protection against accomplishment of 

single seated flight with forgotten spin ballast 

installed. 

Schleicher issued a TN Nr. 4a in 2004 to 

provide instructions to the Aircraft Flight 

Manual (AFM) amendments to address spin 

ballast installation and facilitate two seated 

spin training. However, these instructions 

did not provide proper guidance for the spin 

entry techniques. The safety margin in 

respect to inertia limits was marginal for 

pilot weights less than 70 kg on the front 

seat. 

Furthermore, in one case, it was observed 

that a control surface gap was not sealed in 

accordance with design data approved for 

that aircraft. 

Single seated flight with forgotten spin 

ballast installed, if not corrected, could lead 

to sailplane operation beyond its centre of 

gravity limits. Flights with low inertia 

momentum around Y axis (as a result of the 

low weight crew) could result in reduced 

safety margin in respect to inertia limits. 

Improperly sealed control surface gap 

during spin recovery could lead to significant 

delay of recovery and reduced control of the 

sailplane. 

To address these potential unsafe 

conditions, Schleicher issued TN Nr. 4b for 

ASK 21 model sailplanes and TN Nr. 7 for 

ASK 21 Mi model sailplanes to amend the 

associated AFM and Aircraft Maintenance 

Manual (AMM) procedures and installation 

of a cockpit placard, as applicable to 

sailplane model. 

For the reasons described above, this AD 

requires amendment of the AFM, AMM and 

installation of a cockpit placard. 

The MCAI can be found in the AD 

docket on the Internet at: http://

www.regulations.gov/

#!docketDetail;D=FAA-2014-0019-0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 2595, January 15, 2014) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the 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 2595, 

January 15, 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 2595, 

January 15, 2014). 

Costs of Compliance 

We estimate that this AD will affect 

59 products of U.S. registry. We also 

estimate that it will take about 2.5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $250 per 

product. 

Based on these figures, we estimate 

the cost of the AD on U.S. operators to 

be $27,287.50, or $462.50 per product. 

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: 


pmangrum on DSK3VPTVN1PROD with RULES
18616 Federal Register / Vol. 79, No. 64 / Thursday, April 3, 2014 / Rules and Regulations 

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.

ACTION: Final rule. 

SUMMARY: We are superseding 

airworthiness directive (AD) 2007–03– 

02 for all Rolls-Royce Deutschland 

(RRD) Tay 620–15, Tay 650–15, and Tay 

651–54 turbofan engines. AD 2007–03– 

02 required an ultrasonic inspection 

(UI) of low-pressure (LP) compressor fan 

blades for cracks on certain serial 

number (S/N) Tay 650–15 engines. AD 

2007–03–02 also required, for all Tay 

611–8, 620–15, Tay 650–15, and Tay 

651–54 engines, initial and repetitive 

UIs of LP compressor fan blades. AD 

2007–03–02 also required, for Tay 650– 

15 and Tay 651–54 engines, UIs of LP 

compressor fan blades whenever the 

blade set is removed from one engine 

and installed on a different engine. This 

AD requires additional inspections for 

the affected engines and removal of the 

Tay 611–8 engine from the applicability. 

This AD was prompted by a report of an 

additional engine failure due to 

multiple fan blade separation. We are 

issuing this AD to prevent failure of the 

LP compressor fan blade, engine failure, 

and damage to the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2007–03–02, 

Amendment 39–14913 (72 FR 3936, 

January 29, 2007), (‘‘AD 2007–03–02’’). 

AD 2007–03–02 applied to all RRD Tay 

611–8 and Tay 620–15 turbofan engines 

with LP compressor module, part 

number (P/N) M01100AA or P/N 

M01100AB, installed, and Tay 650–15 

and Tay 651–54 turbofan engines with 

LP compressor module, P/N M01300AA 

or P/N M01300AB, installed. The NPRM 

published in the Federal Register on 

November 29, 2013 (78 FR 71532). The 

NPRM proposed to require a UI of LP 

compressor fan blades for cracks on 

certain S/N Tay 650–15 engines; initial 

and repetitive UIs of LP compressor fan 

blades for all Tay 620–15, Tay 650–15, 

and Tay 651–54 engines; and UIs of LP 

compressor fan blades whenever the 

blade set is removed from one engine 

and installed on a different engine for 

Tay 650–15 and Tay 651–54 engines. 

The NPRM also proposed to require 

additional inspections for the affected 

engines and removal of the Tay 611–8 

engine from the applicability of this AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 71532, November 29, 2013). 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed. 

Costs of Compliance 

We estimate that this AD affects about 

52 engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 4 hours per engine to remove 

and inspect an LP compressor blade set. 

The average labor rate is $85 per hour. 

Prorated parts life will cost about 

$11,750 per engine. Based on these 

figures, we estimate that the cost of this 

AD on U.S. operators is $628,680. 

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
