Airworthiness Directives; Technify 

Motors GmbH Reciprocating Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Technify Motors GmbH TAE 125–02 

reciprocating engines with a dual mass 

flywheel installed. This proposed AD 

was prompted by reports of a gearbox 

drive shaft breaking during starting or 

restarting of the engine. This proposed 

AD would require installation of a start 

phase monitoring system and associated 

specified software. We are proposing 

this AD to prevent overload and failure 

of the gearbox drive shaft, which could 

lead to failure of the engine, in-flight 

shutdown, and loss of control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by September 8, 2015.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2015– 

0055, dated March 31, 2015 (referred to 

hereinafter as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Cases of a broken gearbox drive shaft have 

been reported on aeroplanes equipped with 

TAE 125–02 engines that have a Dual Mass 

Flywheel installed. 

Investigations results showed a possible 

overload of the gearbox drive shaft during 

starting of the engine or during restarting of 

the engine in-flight. 

This condition, if not corrected, could lead 

to engine power loss during flight, possibly 

resulting in loss of control of the aeroplane. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

1383.

The service information describes 

procedures for installing a start phase 

monitoring system and associated 

specified software mapping. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of Germany, and 

is approved for operation in the United 

States. Pursuant to our bilateral 

agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing 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 

products of the same type design. This 

proposed AD would require installation 

of specified software mapping and a 

start phase monitoring system. 

Costs of Compliance 

We estimate that this proposed AD 

affects 97 engines installed on airplanes 

of U.S. registry. We also estimate that it 

would take about 3 hours per engine to 

comply with this proposed AD. The 

average labor rate is $85 per hour. For 

13 of the engines, required parts cost 

about $285 per engine. For 84 of the 

engines, required parts cost about $206 

per engine. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $45,744. 

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 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 this 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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus Model A318, A319, and A321 

series airplanes. This proposed AD was 

prompted by reports of in-flight loss of 

fixed and hinged main landing gear 

(MLG) fairings, and reports of postmodification MLG fixed fairing 

assemblies that have wear and 

corrosion. This proposed AD would 

require, for certain airplanes, repetitive 

replacements of the fixed fairing upper 

and lower attachment studs of both the 

right-hand (RH) and left-hand (LH) 

MLG; and repetitive inspections for 

corrosion, wear, fatigue, cracking, and 

loose studs of each forward stud 

assembly of the fixed fairing door upper 

and lower forward attachment of both 

RH and LH MLG; and replacement if 

necessary. This proposed AD also 

provides an optional terminating 

modification for the repetitive 

replacements of the fixed fairing upper 

and lower attachment studs. We are 

proposing this AD to prevent in-flight 

detachment of an MLG fixed fairing and 

consequent damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by August 24, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2015–0001R1, dated January 

15, 2015 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for all Model A318, 

A319, A320, and Model A321 series 

airplanes. The MCAI states: 

Several occurrences of in-flight loss of 

main landing gear (MLG) fixed and hinged 

fairings were reported. The majority of 

reported events occurred following 

scheduled maintenance activities. One result 

of the investigation was that a discrepancy 

between the drawing and the maintenance 

manuals was discovered. The maintenance 

documents were corrected to prevent misrigging of the MLG fixed and hinged fairings, 

which could induce fatigue cracking. 

Airbus issued Service Bulletin (SB) A320– 

52–1083, providing instructions for a onetime inspection of the MLG fixed fairing 

composite insert and the surrounding area, 

replacement of the adjustment studs at the 

lower forward position and adjustment to the 

new clearance tolerances. That SB was 

replaced by Airbus SB A320–52–1100 (mod 

27716) introducing a re-designed location 

stud, rod end and location plate at the 

forward upper and lower leg fixed-fairing 

positions. Subsequently, reports were 

received of post-mod 27716/post-SB A320– 

52–1100 MLG fixed fairing assemblies with 

corrosion, which could also induce cracking. 

This condition, if not detected and 

corrected, could lead to further cases of inflight detachment of a MLG fixed fairing, 

possibly resulting in injury to persons on the 

ground and/or damage to the aeroplane. 

To address this potential unsafe condition, 

EASA issued AD 2014-0096 [http://

ad.easa.europa.eu/blob/easa_ad_2014_0096_

superseded.pdf/AD_2014-0096_1] to require
