AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 328 

Support Services GmbH Model 328–100 

and –300 airplanes. This proposed AD 

was prompted by reports indicating 

corrosion on the horizontal stabilizer 

bearing supports at the contact surface 

to the horizontal stabilizer rear spar. 

This proposed AD would require 

inspections for corrosion and any other 

damage (i.e., cracking and chafing) of 

the horizontal stabilizer rear bearing 

supports, replacement of the affected 

horizontal stabilizer rear bearing 

supports if necessary, and modification 

of the horizontal stabilizer rear spar. We 

are proposing this AD to address the 

unsafe condition on these products. 

DATES: We must receive comments on 

this proposed AD by July 23, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

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 2017–0239, dated November 

30, 2017 (referred to after this as the 

Mandatory Continuing Airworthiness 

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

an unsafe condition for all 328 Support 

Services GmbH Model 328–100 and 

–300 airplanes. The MCAI states: 

Occurrences were reported on horizontal 

stabilizer bearing supports being found 

corroded at the contact surface to the 

horizontal stabilizer rear spar. The corroded 

area was at the lower flange position, which 

is connected to the stabilizer rear spar and 

not visible without detachment of the fitting. 

Investigation determined that the corrosion is 

triggered by galvanic effect, due to a direct 

contact between the horizontal stabilizer rear 

spar, made from CFRP (carbon fibre 

reinforced plastic), and the aluminium rear 

attachment fitting. 

This condition, if not detected and 

corrected, could lead to failure of the fitting 

and loss of one load path of the horizontal 

stabilizer attachment, possibly resulting in 

reduced control of the aeroplane. 

To address this potential unsafe condition, 

328 Support Services GmbH (328 SSG) 

issued Service Bulletin (SB) SB–328–55–557 

and SB–328J–55–324 to provide instructions 

for inspection of the affected area, 

replacement of the parts, and modification to 

improve corrosion behaviour by 

incorporating of glass fibre layer. 

For the reasons described above, this 

[EASA] AD requires a one-time inspection 

[detailed visual inspection and an eddy 

current inspection for chafing and corrosion] 

of the horizontal stabilizer rear bearing 

supports, and, depending on findings, 

accomplishment of applicable corrective 

action(s) [replacement of the affected 

horizontal stabilizer rear bearing supports]. 

This [EASA] AD also requires a modification 

of the horizontal stabilizer rear spar, 

irrespective of findings.

AD docket on the internet at http://

Related Service Information Under 1 

CFR Part 51 

328 Support Services GmbH has 

issued Service Bulletin SB–328–55–557, 

Revision 1, dated February 1, 2018; and 

Service Bulletin SB–328J–55–324, 

Revision 1, dated February 1, 2018. This 

service information describes a detailed 

visual inspection and an eddy current 

inspection for corrosion and any other 

damage (i.e., cracking and chafing) of 

the horizontal stabilizer rear bearing 

supports, modification of the horizontal 

stabilizer rear spar, and replacement of 

the affected horizontal stabilizer rear 

bearing supports if necessary. These 

documents are distinct since they apply 

to different airplane models. 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. 

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 27 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Detailed visual inspection and eddy current 

inspection.

4 work-hours × $85 per hour = $340 ............. $0 $340 $9,180 

Modification ..................................................... 16 work-hours × $85 per hour = $1,360 ........ 0 1,360 36,720 

We estimate the following costs to do 

any necessary replacement that would 

be required based on the results of the 

proposed inspection. We have no way of 

determining the number of aircraft that 

might need this replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement ................................................................. 24 work-hours × $85 per hour = $2,040 ...................... (*) $2,040 

* We have received no definitive data that would enable us to provide part cost estimates for the on-condition action 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):
