AD 2014-20-12

We are superseding Airworthiness Directive (AD) 75-20-06 for certain Alexandria Aircraft LLC (type certificate previously held by Bellanca Aircraft Corp., Viking Aviation, Inc., and Bellanca, Inc.) Models 14-19-3A, 17-30, 17-30A, 17-31, 17-31A, 17-31ATC, and 17-31TC airplanes. AD 75-20-06 required repetitively inspecting the aft fuselage structure near the top of the vertical side tubing, which connects the horizontal stabilizer carry-through to the upper fuselage longeron, for cracks and installing the manufacturer's service repair kit as a terminating action for the repetitive inspections to repair any cracks found. Since we issued AD 75-20-06, we have determined that installing the service kit has not prevented cracks from occurring. We have also determined that all affected airplane serial numbers should be included in the Applicability section. This AD requires continued repetitive inspections of the aft fuselage structure near the top of the vertical side tubing for cracks and making all necessary replacements of cracked parts. This AD also adds additional serial number airplanes to the Applicability section. We are issuing this AD to correct 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 removing Airworthiness Directive (AD) 75-20-06, Amendment 39-2372 (40 FR 43484, September 22, 1975), and adding the following new AD:

2014-20-12 Alexandria Aircraft LLC: Amendment 39-17985; Docket No. FAA-2014-0438; Directorate Identifier 2014-CE-015-AD.

(a) Effective Date

This AD is effective November 12, 2014.

(b) Affected ADs

This AD supersedes AD 75-20-06, Amendment 39-2372 (40 FR 43484, September 22, 1975, (``AD 75-20-06'')).

(c) Applicability

This AD applies to Alexandria Aircraft LLC (type certificate previously held by Bellanca Aircraft Corp., Viking Aviation, Inc., andBellanca, Inc.) Models 14-19-3A, 17-30, 17-30A, 17-31, 17-31A, 17-31ATC, and 17-31TC airplanes, all serial numbers (S/Ns), certificated in any category.

(d) Subject

Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

This AD was prompted by reports that cracks are still being found in the vertical side fuselage tube (fuselage station 7) in the area near the upper fuselage longeron on airplanes that have had Bellanca Kit SK1234789-0004 installed, which is a terminating action for the repetitive inspections required in AD 75-20-06. We are issuing this AD to detect and correct cracks in either vertical side fuselage tube (F.S. 7), which is adjacent to the horizontal stabilizer carry-through, in the area near the upper fuselage longeron to prevent failure of the horizontal stabilizer. This failure could cause reduced structural integrity of the fuselage and result in loss of control.

(f) Compliance

Comply with this AD within the compliance times specified in paragraphs (g) through (h) of this AD, unless already done.

(g) Inspection

(1) Models 14-19-3A and 17-31A, S/Ns 32-15 through 76-32-163; Models 17-30 and 17-30A, S/Ns 30263 through 76-30811; and Models 17- 31, 17-31TC, and 17-31ATC, S/Ns 30004, and 31004 through 76-31124 (airplanes previously affected by AD 75-20-06): Within the next 100 hours time-in-service (TIS) after the last inspection completed by AD 75-20-06 or within the next 25 hours TIS after November 12, 2014 (the effective date of this AD), whichever occurs later, and repetitively thereafter at intervals not to exceed 100 hours TIS, visually inspect the aft fuselage truss for cracks as specified in paragraph 4.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 75-20-06, Amendment 39-2372 (40 FR 43484, September 22, 1975, (``AD 75-20-06''). AD 75-20-06 applied to certain Alexandria Aircraft LLC (type certificate previously held by Bellanca Aircraft Corp., Viking Aviation, Inc., and Bellanca, Inc.) Models 14- 19-3A, 17-30, 17-30A, 17-31, 17-31A, 17-31ATC, and 17-31TC airplanes. The NPRM published in the Federal Register on July 2, 2014 (79 FR 37679). The NPRM was prompted by reports that cracks are still being found in the vertical side fuselage tube (F.S. 7) in the area near the upper fuselage longeron on airplanes that have had Bellanca Kit SK1234789-0004 installed, which is a terminating action for the repetitive inspections required in AD 75-20-06. The NPRM proposed to retain the inspection requirements of AD 75-20-06, remove the terminating action allowed in AD 75-20-06, and change the applicability toinclude all serial numbers. We are issuing this AD to correct the unsafe condition on these products.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 37679, July 2, 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 37679, July 2, 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 37679, July 2, 2014).

Costs of Compliance

We estimate that this AD affects 847 airplanes of U.S. registry.

[[Page 60328]]

We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspecting the horizontal 1 work-hour x $85 Not applicable............. $85 $71,995
stabilizer fuselage attachment per hour = $85.
tube and carry-thru tube
support bracket (retained
actions from AD 75-20-06). ----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do any necessary replacements that will be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements:

On-Condition Costs ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement of the horizontal stabilizer 30 work-hours x $85 per hour = $575 $3,125
fuselage attachment tube and carry-thru tube $2,550.
support bracket. ----------------------------------------------------------------------------------------------------------------

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 have 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'' underDOT 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.
