Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to revise an existing airworthiness directive (AD) that applies to all Cessna Aircraft Company (Cessna) Models 190, 195 (L-126A,B,C), 195A, and 195B airplanes that are equipped with certain inboard aileron hinge brackets. The existing AD currently requires you to repetitively inspect the affected inboard aileron hinge brackets for cracks or corrosion and replace them if cracks or corrosion is found. Replacement with aluminum brackets would terminate the need for Start Printed Page 1156the repetitive inspections. Since we issued AD 2004-21-08, the FAA, in recent months, has received reports of confusion between the casting number on the aileron hinge bracket and the part number (P/N) called out in the AD. This proposed AD would retain the actions of AD 2004-21-08 while requiring future compliance following a revised service bulletin that clarifies the casting numbers and part numbers to be inspected. We are proposing this AD to correct the unsafe condition on these products.

Discussion

On October 13, 2004, we issued AD 2004-21-08, amendment 39-13828 (69 FR 62396, October 26, 2004), for all Cessna Models 190, 195 (L-126A,B,C), 195A, and 195B airplanes that are equipped with certain inboard aileron hinge brackets. That AD requires you to repetitively inspect the affected inboard aileron hinge brackets for cracks or corrosion and replace them if cracks or corrosion is found. Replacement with aluminum brackets would terminate the need for the repetitive inspections.

AD 2004-21-08 (69 FR 62396, October 26, 2004) resulted from several reports of cracks and corrosion found on the magnesium aileron hinge brackets. Magnesium is known to be susceptible to corrosion. We issued AD 2004-21-08 (69 FR 62396, October 26, 2004) to detect and correct corrosion damage to the inboard aileron hinge brackets. Such damage could result in the brackets cracking across the bearing boss and could lead to the aileron separating from the airplane with consequent reduced or loss of control.

Actions Since Existing AD Was Issued

Since we issued AD 2004-21-08 (69 FR 62396, October 26, 2004), the FAA, in recent months, has received reports of confusion between the casting number on the aileron hinge bracket and the P/N called out in the AD. Due to this misunderstanding, proper inspections and/or replacement of the aileron hinge bracket may not be occurring following the AD. In one report, a service center provided an airworthiness compliance record stating “aileron hinge brackets are of a different part # than those specified in the note.” However, during a later inspection of the bracket, a crack was found through the bearing boss.

Relevant Service Information

We reviewed Cessna Aircraft Company Single Engine Service Bulletin SEB04-1, dated April 26, 2004, and Single Engine Service Bulletin SEB04-01, Revision 1, dated October 3, 2012. The service information describes procedures for:

—Inspecting P/N 0322709 and P/N 0322709-1 inboard aileron hinge brackets for cracks or corrosion; and

—Replacing any bracket found cracked or corroded with a bracket that is FAA-approved and made from aluminum.

Revision 1 of the service information adds casting numbers for the parts to be inspected and clarifies the inspection.

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 all requirements of AD 2004-21-08 (69 FR 62396, October 26, 2004) while requiring future compliance following a revised service bulletin that clarifies the casting numbers and part numbers to be inspected.

Change to Existing AD

This proposed AD would retain all requirements of AD 2004-21-08 (69 FR 62396, October 26, 2004). Since AD 2004-21-08 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table:

Revised Paragraph Identifiers

Requirement in AD 2004-21-08Corresponding requirement in this proposed AD
paragraph (e)(1)paragraph (h)
paragraph (e)(2)paragraph (i)
paragraph (e)(3)paragraph (j)

Costs of Compliance

We estimate that this proposed AD affects 643 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:Start Printed Page 1157

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Inspection of the affected inboard aileron hinge brackets for cracks or corrosion1 work-hour × $85 per hour = $85Not Applicable$851,180 airplanes × $85 = $54,655.

The new requirements of this proposed AD add no additional economic burden.

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 left-hand (LH) brackets3 work-hours × $85 per hour = $255$1,999$2,254
Replacement of right-hand (RH) brackets3 work-hours × $85 per hour = $2551,5921,847
Replacement of LH and RH brackets6 work-hours × $85 per hour = $5104,1014,611

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.
