DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2016-0457; Directorate Identifier 2015-NM-084-AD; 
Amendment 39-18751; AD 2016-25-25]
RIN 2120-AA64


Airworthiness Directives; BAE Systems (Operations) Limited 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting an airworthiness directive (AD) that 
published in the Federal Register. That AD applies to all BAE Systems 
(Operations) Limited Model 4101 airplanes. As published, the Product 
Identification line of the regulatory text contains an error. This 
document corrects that error. In all other respects, the original 
document remains the same.

DATES: This correction is effective March 22, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 7, 
2017 (82 FR 7, January 3, 2017).

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The address for the 
Docket Office (phone: 800-647-5527) is Docket Management Facility, U.S. 
Department of Transportation, Docket Operations, M-30, West Building 
Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 
20590.

FOR FURTHER INFORMATION CONTACT: Todd Thompson, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
1601 Lind Avenue SW., Renton, WA 98057-3356; telephone 425-227-1175; 
fax 425-227-1149.

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 2016-25-25, 
Amendment 39-18751 (82 FR 7, January 3, 2017) (``AD 2016-25-25''), 
currently requires repetitive detailed inspections for cracks, 
corrosion, and other defects of the rear face of the wing rear spar, 
and repair if necessary, for all BAE Systems (Operations) Limited Model 
4101 airplanes.
    As published, the Product Identification line of the regulatory 
text contains an error. The Product Identification line incorrectly 
identifies Bombardier as the product manufacturer, but should have 
identified BAE Systems (Operations) Limited. All other references to 
the product manufacturer appear correctly as BAE Systems (Operations) 
Limited throughout the preamble and regulatory text of AD 2016-25-25.
    No other part of the preamble or regulatory information has been 
changed; therefore, only the changed portion of the final rule is being 
published in the Federal Register.
    The effective date of this AD remains February 7, 2017.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Correction

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Corrected]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-17079 (77 FR 
36127, June 18, 2012), and adding the following new airworthiness 
directive (AD):

2016-25-25 BAE Systems (Operations) Limited: Amendment 39-18751; 
Docket No. FAA-2016-0457; Directorate Identifier 2015-NM-084-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective February 7, 2017.

(b) Affected ADs

    This AD replaces AD 2012-11-15, Amendment 39-17079 (77 FR 36127, 
June 18, 2012) (``AD 2012-11-15'').

(c) Applicability

    This AD applies to BAE Systems (Operations) Limited Model 4101 
airplanes, certificated in any category, all models and all serial 
numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Reason

    This AD was prompted by new reports of cracking found in the 
wing rear spar and technical analysis results, which confirmed that 
the crack initiation and propagation are due to fatigue, with no 
indication of any other crack initiation mechanism (e.g., stress 
corrosion). We are issuing this AD to detect and correct cracking in 
the wing rear spar, which could propagate to a critical length, 
possibly affecting the structural integrity of the area and 
resulting in a fuel tank rupture, with consequent damage to the 
airplane and possible injury to its occupants.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Inspections and Repair

    Within 30 days after February 7, 2017 (the effective date of 
this AD), or within 1,600 flight cycles since the most recent 
detailed inspection was done as specified in BAE Systems Alert 
Service Bulletin J41-A57-029, whichever occurs later: Do a detailed 
inspection for cracks, corrosion, and other defects (defects include 
scratches, dents, holes, damage to fastener holes, or damage to 
surface protection and finish) of the rear face of the wing rear 
spars, in accordance with the Accomplishment Instructions of BAE 
Systems Alert Service Bulletin J41-A57-029, Revision 3, dated April 
8, 2014. Repeat the inspection thereafter at intervals not to exceed 
1,600 flight cycles.
    (1) If any cracking, corrosion, or other defect is found within 
the criteria defined in Chapter 57, Wings, of the Jetstream Series 
4100 Structural Repair Manual (SRM), Volume 1, Publication Ref. No. 
(Transmittal No.) SA 4-4100/SRM/400, Revision 32, dated October 15, 
2014 (``Chapter 57 of the SRM''): Before further flight, repair the 
affected area, in accordance with the repair instructions of Chapter 
57 of the SRM.

[[Page 14602]]

    (2) If any cracking, corrosion, or other defect is found 
exceeding the criteria defined in Chapter 57 of the SRM: Before 
further flight, repair using a method approved by the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; 
or the European Aviation Safety Agency (EASA); or BAE Systems 
(Operations) Limited's EASA Design Organization Approval (DOA).

(h) Repair Does Not Constitute Terminating Action Except for Certain 
Repairs

    Accomplishment of a repair, as required by paragraphs (g)(1) and 
(g)(2) of this AD, does not constitute terminating action for the 
repetitive inspections required by paragraph (g) of this AD, unless 
the approved repair required by paragraph (g)(2) of this AD states 
otherwise (e.g., the approved repair states the repair terminates 
the inspections for the repaired area only).

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to ATTN: Todd 
Thompson, Aerospace Engineer, International Branch, ANM-116, 
Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, 
WA 98057-3356; telephone 425-227-1175; fax 425-227-1149.
    Information may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Contacting the Manufacturer: As of February 7, 2017 (the 
effective date of this AD), for any requirement in this AD to obtain 
corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, International 
Branch, ANM-116, Transport Airplane Directorate, FAA; or the EASA; 
or BAE Systems (Operations) Limited's EASA DOA. If approved by the 
DOA, the approval must include the DOA-authorized signature.
