Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD 

CF–2017–25, dated July 31, 2017 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for certain Bombardier, Inc., 

Model DHC–8–102, –103, and –106 

airplanes, Model DHC–8–200 series 

airplanes, and Model DHC–8–300 series 

airplanes. The MCAI states: 

There have been several reports of arcing 

and smoke emanating from the windshields. 

Investigation of these incidents revealed that 

de-icing fluid and water could enter between 

the windshields and side window posts, 

leading to possible damage of the windshield 

heater terminal lugs creating arcing and 

smoke. In addition, investigation also 

revealed that the windshield heater terminal 

lugs tend to loosen over time. Loose terminal 

lugs could also have a similar effect of arcing 

and smoke. Both events could lead to 

burning of the lugs and, due to the excessive 

heat, cracking of the windshields. If not 

corrected, these conditions could cause a loss 

of cabin pressure resulting in an emergency 

descent. 

Required actions include revising the 

maintenance or inspection program, as 

applicable, to incorporate MRB tasks for 

general visual inspections of the 

windshield moisture seal (for signs of 

cracking, erosion, wear, or other 

damage), re-torqueing the windshield 

heater terminal lugs, applying sealant to 

the windshield heater screw heads, 

doing a chemical cleaning of the wiring 

and components, doing a general visual 

inspection of the wiring and 

components for signs of cracking, 

erosion, wear, or other damage, doing an 

operational test of the pilot’s and copilot’s windshield heating system, and 

repair if necessary. 

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–2018– 

0553. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued Service 

Bulletin 8–30–41, Revision A, dated 

March 24, 2017. This service 

information describes procedures for retorqueing the windshield heater 

terminal lugs and applying Humisel 

coating to the screw heads of the 

windshield heater, doing a chemical 

cleaning and general visual inspection 

of the wiring and components, and 

doing an operational test of the 

windshield heating system. 

Bombardier has also issued the 

following service information, which 

describes airworthiness limitation tasks 

for a general visual inspection of the 

windshield moisture seal. These 

documents are distinct since they apply 

to different airplane models.

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. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

The MCAI calls for revising the 

maintenance or inspection program, as 

applicable, by incorporating certain 

temporary revisions (TRs) into the 

Program Support Manual (PSM). This 

proposed AD instead calls for 

incorporating certain task cards into the 


daltland on DSKBBV9HB2PROD with PROPOSALS
Federal Register / Vol. 83, No. 130 / Friday, July 6, 2018 / Proposed Rules 31495 

PSM. We have determined that these 

task cards address the unsafe condition 

in the same manner that the TRs would. 

Costs of Compliance 

We estimate that this proposed AD 

affects 63 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

3 work-hours × $85 per hour = $255 .......................................................................................... $0 $255 $16,065 

We have also determined that revising 

the maintenance or inspection program 

takes an average of 90 work-hours per 

operator, although we recognize that 

this number may vary from operator to 

operator. In the past, we have estimated 

that this action takes 1 work-hour per 

airplane. Since operators incorporate 

maintenance or inspection program 

changes for their affected fleet(s), we 

have determined that a per-operator 

estimate is more accurate than a perairplane estimate. Therefore, we 

estimate the total cost per operator to be 

$7,650 (90 work-hours × $85 per workhour). 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this proposed AD. 

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. 

This proposed AD is issued in 

accordance with authority delegated by 

the Executive Director, Aircraft 

Certification Service, as authorized by 

FAA Order 8000.51C. In accordance 

with that order, issuance of ADs is 

normally a function of the Compliance 

and Airworthiness Division, but during 

this transition period, the Executive 

Director has delegated the authority to 

issue ADs applicable to transport 

category airplanes to the Director of the 

System Oversight Division. 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 airworthiness 

directive (AD):

the windshields and side window posts, 

which could lead to burning of the lugs and 

cracking of the windshields, and could 

ultimately cause a loss of cabin pressure, 

resulting in an emergency descent. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Maintenance or Inspection Program 

Revision 

Within 30 days after the effective date of
