AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede Airworthiness Directive (AD) 75-20-06, which applies 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. AD 75-20-06 requires 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 proposed AD would require continued repetitive inspections of the aft fuselage structure near the top of the vertical side tubing for cracks and making all necessary replacements of cracks parts. This proposed AD would also add additional serial number airplanes to the Applicability section. We are proposing this AD to correct the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by August 18, 2014.

Discussion

On September 12, 1975, we issued AD 75-20-06, Amendment 39-2372 (40 FR 13184, September 22, 1975), (“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 requires 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 (Bellanca Kit SK1234789-0004) as a terminating action for the repetitive inspections to repair any cracks found. AD 75-20-06 resulted from reports of cracks found in the aft fuselage structure near the horizontal stabilizer carry-through on the Model 17 series airplanes. We issued AD 75-20-06 to detect and correct cracks in either vertical side fuselage tube (fuselage station (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.

Actions Since AD 75-20-06 Was Issued

Since we issued AD 75-20-06, we have received 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.

Relevant Service Information

We reviewed Alexandria Aircraft LLC Bellanca Service Letter 85, Revision B, dated April 8, 2004. The service letter describes procedures for repetitively inspecting the horizontal stabilizer fuselage attachment tube and carry-thru tube support bracket for cracks and replacing any cracked parts found.

FAA's Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

Proposed AD Requirements

This proposed AD would retain the inspection requirements of AD 75-20-06 and remove the terminating action allowed in AD 75-20-06.Start Printed Page 37680

Costs of Compliance

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

We estimate the following costs to comply with this proposed AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Inspecting the horizontal stabilizer fuselage attachment tube and carry-thru tube support bracket (retained actions from AD 75-20-06)1 work-hour × $85 per hour = $85Not applicable$85$71,995

We estimate the following costs to do any necessary replacements 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 these replacements:

On-Condition Costs

ActionLabor costParts costCost per product
Replacement of the horizontal stabilizer fuselage attachment tube and carry-thru tube support bracket30 work-hours × $85 per hour = $2,550$575$3,125

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 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 that the 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.

2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 75-20-06, Amendment 39-2372 (40 FR 13184, September 22, 1975), and adding the following new AD:

End Amendment Part

Alexandria Aircraft LLC: Docket No. FAA-2014-0438; Directorate Identifier 2014-CE-015-AD.

(a) Comments Due Date

The FAA must receive comments on this AD action by August 18, 2014.

(b) Affected ADs

This AD supersedes AD 75-20-06, Amendment 39-2372 (40 FR 13184, 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., and Bellanca, 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.
