Airworthiness Directives; Cessna 

Aircraft Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Cessna Aircraft Company Model 500, 

501, 550, 551, S550, 560, and 650 

airplanes. This proposed AD was 

prompted by reports of smoke and/or 

fire in the tailcone caused by sparking 

due to excessive wear of the brushes in 

the air conditioning (A/C) motor. This 

proposed AD would require inspections 

to determine if certain A/C compressor 

motors are installed and to determine 

the accumulated hours on certain A/C 

compressor motor assemblies; and 

repetitive replacement of the brushes in 

the A/C compressor motor assembly, or, 

as an option to the brush replacement, 

deactivation of the A/C system and 

placard installation; and return of 

replaced brushes to Cessna. We are 

proposing this AD to prevent the 

brushes in the A/C motor from wearing 

down beyond their limits, which could 

result in the rivet in the brush 

contacting the commutator, causing 

sparks and consequent fire and/or 

smoke in the tailcone with no means to 

detect or extinguish the fire and/or 

smoke. 

DATES: We must receive comments on 

this proposed AD by March 9, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

about this proposed AD. 

Discussion 

We have received reports of smoke/

fire (three reports of fire) in the tailcone 

of Cessna Aircraft Company Model 525, 

550, and 560 airplanes, where 

investigation revealed brushes had worn 


emcdonald on DSK67QTVN1PROD with PROPOSALS
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 3517 

beyond their limits on the part number 

(P/N) 1134104–1 A/C compressor 

motors. The motor assembly is located 

in the airplane tailcone where 

flammable fluids in the form of fuel 

lines and hydraulics are present. There 

is no fire detection or extinguishing 

system in the tailcone. We are proposing 

this AD to prevent the brushes in the air 

conditioning motor from wearing down 

beyond their limits, which could result 

in the rivet in the brush contacting the 

commutator, causing sparks and 

consequent fire and/or smoke in the 

tailcone with no means to detect or 

extinguish the fire and/or smoke. 

The subject part, P/N 1134104–1 A/C 

compressor motors, might also be 

installed on Model 500, 501, 551, S550, 

and 650 airplanes. Therefore, those 

Model 500, 501, 551, S550, and 650 

airplanes might be subject to the unsafe 

condition revealed on Model 525, 550, 

and 560 airplanes. 

Related ADs 

AD 2013–09–11, Amendment 39– 

17453 (78 FR 32349, May 30, 2013), was 

issued for certain Cessna Aircraft 

Company Model 500, 501, 550, 551, 

S550, 560, 560XL, and 650 airplanes. 

AD 2013–09–11 requires inspecting to 

determine if certain A/C compressor 

motors are installed and to determine 

the accumulated hours on certain A/C 

compressor motor assemblies; and 

repetitive replacement of the brushes in 

the A/C compressor motor assembly, or, 

as an option to the brush replacement, 

deactivation of the A/C system and 

placard installation; and return of 

replaced brushes to Cessna. 

After AD 2013–09–11, Amendment 

39–17453 (78 FR 32349, May 30, 2013), 

was published the FAA received several 

questions asking if AD 2013–09–11 is 

applicable to airplanes having an air 

conditioning system installed via any of 

the following Fort Worth Airworks 

supplemental type certificates (STCs): 

• SA3849SW (http://rgl.faa.gov/

rgstc.nsf/0/5FAD7ABA3EAA464

C86257C1A0069F239?OpenDocument

&Highlight=sa8918sw). 

The A/C compressor motor part 

numbers installed via these STCs are the 

same as in AD 2013–09–11, except the 

prefix ‘‘FWA’’ has been added to the 

part numbers of the A/C compressor 

motor installed via the STCs 

(FWA1134104–1 or FWA1134104–5). 

Based on a discussion between the 

FAA and Cessna, we determined that 

AD 2013–09–11, Amendment 39–17453 

(78 FR 32349, May 30, 2013), should 

also apply to A/C compressor motor 

airplanes with P/N FWA1134104–1 or 

P/N FWA1134104–5 installed. Instead 

of superseding AD 2013–09–11 to add 

these airplanes to the applicability, the 

FAA is issuing this new proposed AD 

applicable only to airplanes with P/N 

FWA1134104–1 or P/N FWA1134104–5 

installed. 

Cessna Model 560XL airplanes are not 

included in the applicability of this 

proposed AD because the Fort Worth 

Airworks STCs identified previously are 

not installed on that airplane model. 

AD 2013–08–05, Amendment 39– 

17422 (78 FR 24343, April 25, 2013), 

addresses the same unsafe condition 

that prompted this proposed AD. AD 

2013–08–05 is applicable to Cessna 

Aircraft Company Model 525 airplanes. 

The Fort Worth Airworks STCs 

referenced above do not apply to the 

Cessna Model 525 airplanes; therefore, 

this proposed AD does not affect AD 

2013–08–05. 

After AD 2013–08–05, Amendment 

39–17422 (78 FR 24343, April 25, 2013); 

and AD 2013–09–11, Amendment 39– 

17453 (78 FR 32349, May 30, 2013); 

were published, the FAA determined 

that there are some airplanes on which 

the air conditioning motor system had 

been installed via the Fort Worth 

Airworks STCs mentioned previously, 

and an A/C compressor hour meter was 

not part of the type design. To assist in 

future compliance with this proposed 

AD, an A/C compressor hour meter may 

be installed. The installation can be 

done using Cessna Service Letter CIL– 

21–02, dated January 23, 2014, or by a 

method approved by the FAA.

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require an 

inspection to determine if certain A/C 

compressor motors are installed; an 

inspection of the A/C compressor hour 

meter for certain A/C compressor 

motors to determine the number of 

hours accumulated on the motors; and 

repetitive replacement of the brushes in 

the A/C compressor motor assembly, or 

optional deactivation of the A/C system 

and installation of a placard prohibiting 

use of the A/C system until replacement 

of the brushes. This proposed AD would 

also require, when the brushes are 

replaced, reporting aircraft information 

related to the replacement of the 

brushes and sending the replaced motor 

brushes to Cessna Aircraft Company for 

two replacement cycles. 

Interim Action 

We consider this proposed AD 

interim action. The reporting data 

required by this proposed AD will 

enable us to obtain better insight into 

brush wear. The reporting data will also 

indicate if the replacement intervals we 

established are adequate. After we 

analyze the reporting data received, we 

might consider further rulemaking. 

Costs of Compliance 

We estimate that this proposed AD 

affects 333 airplanes of U.S. registry.

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to the FAA at 800 

Independence Ave. SW., Washington, 

DC 20591, ATTN: Information 

Collection Clearance Officer, AES–200. 

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, 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.

(d) Subject 

Air Transport Association (ATA) of 

America 21, Air Conditioning. 

(e) Unsafe Condition 

This AD was prompted by reports of smoke 

and/or fire in the tailcone caused by sparking 

due to excessive wear of the brushes in the 

air conditioning (A/C) motor. We are issuing 

this AD to prevent the brushes in the A/C 

motor from wearing down beyond their 

limits, which could result in the rivet in the 

brush contacting the commutator, causing 

sparks and consequent fire and/or smoke in 

the tailcone with no means to detect or 

extinguish the fire and/or smoke. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspection for Part Number (P/N) 

Within 30 days or 10 flight hours after the 

effective date of this AD, whichever occurs 

first: Inspect the A/C compressor motor to 

determine whether P/N FWA1134104–1 or P/ 

N FWA1134104–5 is installed. A review of 

airplane maintenance records is acceptable in 

lieu of this inspection if the part number of 

the A/C compressor motor can be 

conclusively determined from that review. 

(h) Inspection of Compressor Hour Meter 

and Maintenance Records 

If, during the inspection required by 

paragraph (g) of this AD, any A/C compressor 

motor having P/N FWA1134104–1 or P/N 

FWA1134104–5 is found: Within 30 days or 

10 flight hours after the effective date of this 

AD, whichever occurs first, determine the 

hour reading on the A/C compressor hour 

meter as specified in paragraphs (h)(1) and 

(h)(2) of this AD. 

(1) Inspect the number of hours 

accumulated on the A/C compressor hour 

meter. 

(2) Check the airplane logbook for any 

entry for replacing the A/C compressor motor 

brushes with new brushes, or for replacing 

the compressor motor or compressor 

condenser module assembly (pallet) with a 

motor or assembly that has new brushes. 

(i) If the logbook contains an entry for 

replacement of parts, as specified in 

paragraph (h)(2) of this AD, determine the 

number of hours accumulated on the A/C 

compressor motor brushes by comparing the 

number of hours on the compressor motor 

since replacement and use this number in 

lieu of the number determined in paragraph 

(h)(1) of this AD. 

(ii) If, through the logbook check, a 

determination cannot be made regarding the 

number of hours accumulated on the A/C 

compressor motor brushes, as specified in 

paragraph (h)(2) of this AD, use the number 

of hours accumulated on the A/C compressor 

hour meter determined in paragraph (h)(1) of

[Docket No. FAA–2014–1051; Directorate 

Identifier 2014–NM–171–AD]

Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Airbus Model A319, A320, and A321 

series airplanes. This proposed AD was 

prompted by reports that on airplanes 

equipped with sharklets, discretes (used 

to activate the load alleviation function) 

are connected on various flight 

computers using the same ground point. 

In these cases, the ground point 

segregation is no longer effective and a 

single failure could lead to loss of 

sharklet identification by flight 

computers causing a return to the wing 

tip fence (no sharklet configuration) 

performance. This proposed AD would 

require modification of the sharklet 

ground connection. We are proposing 

this AD to prevent loss of sharklet 

identification by the flight computers 

and subsequent reduced control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by March 9, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
