AD 2014-07-09

We are adopting a new airworthiness directive (AD) for British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as inadequate instructions for inspection for corrosion on the rudder upper hinge bracket and certain internal wing and drainage paths. We are issuing this AD to require actions to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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 [Amended]

0 2. The FAA amends Sec. 39.13 by adding the following new AD:

2014-07-09 British Aerospace Regional Aircraft: Amendment 39-17823; Docket No. FAA-2014-0042; Directorate Identifier 2013-CE-050-AD.

(a) Effective Date

This airworthiness directive (AD) becomes effective May 27, 2014.

(b) Affected ADs

None.

(c) Applicability

This AD applies to British Aerospace Regional Aircraft Jetstream Series 3101 and Model 3201 airplanes, all serial numbers, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 5: Time Limits.

(e) Reason

This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as inadequate instructions for inspection for corrosion on the rudder upper hinge bracket and certain internal wing stations and drainage paths. We are issuing this AD to prevent, detect, and correct corrosion on the rudder upper hinge bracket and internal wing, which could lead to reduced structural integrity of the airplane with consequent loss of control.

(f) Actions and Compliance

Comply with this AD within the compliance times specified in paragraphs (f)(1) through (f)(4) of this AD, including all subparagraphs, unless already done:
(1) After May 27, 2014 (the effective date of this AD), except as required by paragraph (f)(2) of this AD, within the thresholds and intervals specified, incorporate into the FAA-approved maintenance program BAE Systems (Operations) Limited Jetstream Series 3100 & 3200 Corrosion Prevention and Control Programme, Manual Ref. JS/CPCP/01, Revision 6, dated November 15, 2010, in its entirety.
(2) Within 2 years after May 27, 2014 (the effective date of this AD), do the initial inspections specified in tasks 200/EX/01 C2 and 3/400/IN/01 C2 in BAE Systems (Operations) Limited Jetstream Series 3100 &

[[Page 22369]]

3200 Corrosion Prevention and Control Programme, Manual Ref. JS/ CPCP/01, Revision 6, dated November 15, 2010.
(3) If any discrepancy, particularly corrosion, is found during any inspections or tasks required by paragraphs (f)(1) and (f)(2) of this AD, within the compliance time specified, repair or replace, as applicable, all damaged structural parts and components and do the maintenance procedures for corrective action following BAE Systems (Operations) Limited Jetstream Series 3100 & 3200 Corrosion Prevention and Control Programme, Manual Ref. JS/CPCP/01, Revision 6, dated November 15, 2010. If no compliance time is defined, do the applicable corrective action before further flight.
(4) You may comply with the requirements of paragraphs (f)(1) and (f)(2) of this AD by incorporating BAE Systems (Operations) Limited Jetstream Series 3100 & 3200 Corrosion Prevention and Control Programme, Manual Ref. JS/CPCP/01, Revision 6, dated November 15, 2010, into your maintenance program (instructions for continued airworthiness) and complying with that program.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. The NPRM was published in the Federal Register on January 31, 2014 (79 FR 5323). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states:

Compliance with the inspections in the Corrosion Prevention and Control Programme (CPCP) has been identified as a mandatory action for continued airworthiness and UK CAA AD 003-04-94 was issued to require operators to comply with those inspection instructions.
Since the issuance of that AD, reports have been received of finding extensive corrosion on the rudder upper hinge bracket. Although there is an existing zonal inspection of the area in the CPCP, it has been concluded that this is inadequate to identify the corrosion on this bracket and consequently, a new specific inspection of the rudder upper hinge bracket,

[[Page 22368]]

task 200/EX/01 C2, has been added to the CPCP, currently at Revision 6. Failure of the rudder upper hinge bracket could lead to the onset of flutter and loss of control of the aeroplane.
In addition, although the CPCP already included a wing internal inspection to check for corrosion and to verify that all drainage paths are clear, prompted by feedback from the fleet sampling programme, a new, more specific, inspection of wing stations 36, 51 and 83, together with a check of the drainage paths, has been introduced into the CPCP through task 3/400/IN/01 C2. Failure to comply with these instructions could result in an unsafe condition.
For the reasons described above, this AD retains the requirements of UK CAA AD 003-04-94, which is superseded, and requires the implementationof the new inspections.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2014-0042-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 5323, January 31, 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 the 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 5323, January 31, 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 5323, January 31, 2014).

Costs of Compliance

We estimate that this AD will affect 66 products of U.S. registry. We also estimate that it would take about 100 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of the AD on U.S. operators to be $561,000, or $8,500 per product.
The scope of damage found in the required inspection could vary significantly from airplane to airplane. We have no way of determining how much damage may be found on each airplane or the cost to repair damaged parts on each airplane or the number of airplanes that may require repair.

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 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.
