(c) Applicability 

This AD applies to all General Electric 

Company (GE) CF6–80E1 turbofan engines 

with rotating compressor discharge pressure 

(CDP) seals, part number (P/N) 1669M73P02, 

installed. 

(d) Unsafe Condition 

This AD was prompted by reports from the 

manufacturer of cracks in the teeth of two 

rotating CDP seals found during engine shop 

visits. We are issuing this AD to prevent 

cracking of the CDP seal teeth, which can 

lead to uncontained part release, damage to 

the engine, and damage to the airplane. 

(e) Compliance 

(1) Comply with this AD within the 

compliance times specified, unless already 

done. 

(2) After the effective date of this AD, strip 

coating, inspect, and recoat the teeth of the 

rotating CDP seal, P/N 1669M73P02, in 

accordance with paragraph 3.C.(2) of GE 

Service Bulletin (SB) No. CF6–80E1 S/B 72– 

0529, Revision 1, dated August 21, 2015, as 

follows: 

(i) For engines that have had stationary 

CDP seal, P/N 1347M28G02, repaired or 

replaced, strip coating, inspect, and recoat 

the rotating CDP seal at the next engine shop 

visit. 

(ii) For engines that have not had 

stationary CDP seal, P/N 1347M28G02, 

repaired or replaced, strip coating, inspect, 

and recoat the rotating CDP seal at the next 

part exposure. 

(f) Definitions 

(1) For the purpose of this AD, part 

exposure is defined as removal of the 

compressor rear frame from the high-pressure 

compressor module. 

(2) For the purpose of this AD, an engine 

shop visit is defined as the induction of an 

engine into the shop for maintenance 

involving the separation of pairs of major 

mating engine flanges, except that the 

separation of engine flanges solely for the 

purposes of transportation without 

subsequent engine maintenance does not 

constitute an engine shop visit. 

(g) Credit for Previous Action 

If you stripped, inspected, and recoated the 

CDP seal, P/N 1669M73P02, using the 

procedures in ESM 72–31–10, REPAIR 002 of 

the GE CF6–80E1 (GEK99376) Engine 

Manual, Revision 42, dated March 15, 2014, 

or earlier versions, then you met the 

requirements of this AD. 

(h) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

FAA, may approve AMOCs to this AD. Use 

the procedures found in 14 CFR 39.19 to 

make your request. You may email your 

request to: ANE-AD-AMOC@faa.gov.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. This proposed AD was 

prompted by the discovery of a number 

of incorrectly calibrated angle of attack 

(AOA) transducers installed in the stall 

protection system. This proposed AD 

would require replacement of 

incorrectly calibrated AOA transducers. 

We are proposing this AD to detect and 

replace incorrectly calibrated AOA 

transducers; incorrect calibration of the 

transducers could result in late 

activation of the stick pusher. 

DATES: We must receive comments on 

this proposed AD by January 4, 2016.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2015–17, 

effective July 16, 2015 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model CL– 

600–2B19 (Regional Jet Series 100 & 

440) airplanes. The MCAI states: 

It was discovered that a number of [angle 

of attack] AOA transducers installed on 

Bombardier CL–600–2B19 aeroplanes were 

incorrectly calibrated due to a quality control 

problem at both the production and repair 

facilities. Incorrect calibration of the AOA 

transducer could result in a late activation of 

the stick pusher. 

This [Canadian] AD mandates the 

replacement of the incorrectly calibrated 

AOA transducer. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

4814. 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc. has issued 

Bombardier Service Bulletin 601R–27– 

164, dated March 30, 2015. The service 

information describes procedures for 

replacement of incorrectly calibrated 

AOA transducers with correctly 

calibrated AOA transducers. This 

service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section of 

this NPRM. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

affects 575 airplanes of U.S. registry. 

We also estimate that it would take 

about 4 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $10,000 per 

product. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $5,945,500, or 

$10,340 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: 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 99–16–01, 

for certain Airbus Model A300 B4–600, 

B4–600R, and F4–600R series airplanes, 

and Model A300 C4–605R Variant F 

airplanes (collectively called Model 

A300–600 series airplanes). AD 99–16– 

01 currently requires repetitive 

inspections of certain bolt holes where 

parts of the main landing gear (MLG) are 

attached to the wing rear spar, and 

repair if necessary. Since we issued AD– 

99–16–01, we have determined that the 

risk of cracking in the rear spar is higher 

than initially determined. This 

proposed AD would add airplanes to the 

applicability, reduce the compliance 

times and repetitive intervals for the 

inspections, and change the inspection 

procedures. We are proposing this AD to 

detect and correct cracking of the rear 

spar of the wing, which could result in 

reduced structural integrity of the 

airplane.

this proposed AD by January 4, 2016.
