ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all BAE 

Systems (Operations) Limited Model 

BAe 146 series airplanes, and Model 

Avro 146–RJ series airplanes. This AD 

was prompted by a report of a 

pressurization problem on an airplane 

during climb-out; a subsequent 

investigation showed a crack in the 

fuselage skin. This AD requires require 

repetitive external eddy current 

inspections on the aft skin lap joints of 

the rear fuselage for cracking, corrosion, 

and other defects, and repair if 

necessary. We are issuing this AD to 

detect and correct cracking, corrosion, 

and other defects, which could affect 

the structural integrity of the airplane. 

DATES: This AD becomes effective May 

19, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of May 19, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all BAE Systems (Operations) 

Limited Model BAe 146 series airplanes, 

and Model Avro 146–RJ series airplanes. 

The NPRM published in the Federal 

Register on September 3, 2014 (79 FR 

52260). 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2013–0207, dated September 

9, 2013 (referred to after this as the 

Mandatory Continuing Airworthiness 

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

an unsafe condition for all BAE Systems 

(Operations) Limited Model BAe 146 

series airplanes, and Model Avro 146– 

RJ series airplanes. The MCAI states: 

In 2012, a pressurisation problem occurred 

on an AVRO 146–RJ100 aeroplane during 

climb-out. Subsequent investigation results 

identified a 42.87 inch (1089 mm) long crack 

in the fuselage skin in the rear fuselage drum, 

near the rear passenger door. The skin crack 

had initiated in the step of the skin land 

adjacent to a lap joint. In addition to the skin 

crack, cracks were found in Frames 41X and 

42. 

This condition, if not detected and 

corrected, could lead to degradation of the 

structural integrity of the aeroplane. 

Prompted by this finding, BAE Systems 

(Operations) Ltd issued Inspection Service 

Bulletin (ISB) 53–239, providing instructions 

to inspect the internal area of the rear 

fuselage drum for cracks, corrosion and any 

other defects and EASA issued AD 2012– 

0178 [http://ad.easa.europa.eu/blob/easa_

ad_2012_0178_Superseded.pdf/AD_2012- 

0178_1] which required accomplishment of a 

one-time inspection of the affected fuselage 

area and, depending on findings, repair of 

cracked structural items. 

Following the issuance of that [EASA] AD, 

some new information on additional damage 

found on the aeroplane that had the 

pressurisation problem resulted in a further 

review of the cracking event. This review 

concluded that the event was more serious 

than previously considered and that the 

compliance time must be reduced in order to 

mitigate the risk of cracking on other 

aeroplanes. As a result, EASA issued AD 

2012–0184 [http://ad.easa.europa.eu/blob/

easa_ad_2012_0184_superseded.pdf/AD_

2012-0184_1] which superseded EASA AD 

2012–0178. 

After analysing the responses to EASA AD 

2012–0184, which covered the initial 

inspection of stringer 30, left hand (LH) and 

right hand (RH), BAE Systems (Operations) 

Ltd also assessed the similar design features 

at other skin lands in the rear fuselage drum, 

namely at stringer 2 right and stringers 11 

and 18, LH and RH. As a result, they 

determined that inspections at the other 

stringers would be required and also that 

repeat inspections of all these stringers 

would be necessary. Consequently, BAE 

Systems (Operations) Ltd ISB.53–239 

Revision 1 and 2 were issued to include these 

new inspections. 

For the reasons described above, this 

[EASA] AD retains the requirements of EASA 

AD 2012–0184, which is superseded, and 

requires accomplishment of additional 

inspections of the affected fuselage area, 

including repetitive inspections, and 

depending on findings, repair of cracked 

structural items. 

The required actions include 

repetitive external eddy current 

inspections on the aft skin lap joints of 

the rear fuselage for cracking, corrosion, 

and other defects, and repair if 

necessary. You may examine the MCAI 

in the AD docket on the Internet at

Actions Since Issuance of NPRM (79 FR 

52260, September 3, 2014) 

Since we issued the NPRM (79 FR 

52260, September 3, 2014), we have 

received BAE Systems (Operations) 

Limited Inspection Service Bulletin 53– 

239, Revision 3, dated May 7, 2014. The 

new service information includes minor 

editorial changes. 

We have revised paragraph (g)(1) of 

this AD to refer to BAE Systems 

(Operations) Limited Inspection Service 

Bulletin 53–239, Revision 3, dated May 

7, 2014. We have also revised paragraph 

(i) of this AD to provide credit for BAE 

Systems (Operations) Limited 

Inspection Service Bulletin 53–239, 

Revision 2, dated July 15, 2013. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 52260, September 3, 2014) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed, except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

52260, September 3, 2014) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 52260, 

September 3, 2014). 

Related Service Information Under 1 

CFR Part 51 

BAE Systems (Operations) Limited 

has issued Inspection Service Bulletin 

53–239, Revision 3, dated May 7, 2014. 

The service information describes an 

external eddy current inspection on the 

aft skin lap joints of the rear fuselage for 

cracking, corrosion, and other defects, 

and repair. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. This service information is 

reasonably available; see ADDRESSES for 

ways to access this service information. 

Costs of Compliance 

We estimate that this AD affects 1 

airplane of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Inspection ......... 8 work-hours × $85 per hour = $680 per inspection cycle .. $0 $680 per inspection 

cycle.

$680 per inspection 

cycle. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this 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. 

Regulatory Findings 

We determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

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 that this AD: 

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.
