Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on September 18, 2012 (77 FR 57531). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

An occurrence has been reported of an engine fire during ground run of a S10–VT powered sailplane. The investigation results indicated that an unapproved fuel hose was installed in the engine fuel system of thataeroplane. Subsequent survey of some Nregistered S 10 aeroplanes revealed more cases of installation of unapproved fuel, oil and cooling hoses on sailplanes engine systems.

This condition, if not detected and corrected, could lead to a system leak with subsequent engine fire, possibly resulting in damage to the sailplane and/or injury of occupants.

Prompted by these findings, Stemme GmbH developed a procedure for identification of these hoses, to have them removed from service.

For the reasons described above, this AD requires a one-time review of the sailplane’s maintenance records to determine whether a serviceable engine hose kit for fuel, oil and cooling systems has been installed and, depending on findings, replacement of the affected hoses with serviceable parts.



### You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (77 FR 57531, September 18, 2012) 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 (77 FR 57531, September 18, 2012) for correcting the unsafe condition; and


## 71488 Federal Register / Vol. 77, No. 232 / Monday, December 3, 2012 / Rules and Regulations

• Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 57531, September 18, 2012).
Costs of Compliance

We estimate that this AD will affect 63 products of U.S. registry. We alsoestimate that it will take about .5 workhour 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 this AD on U.S. operators to be $2,677.50, or $42.50 per product.

In addition, we estimate that any necessary follow-on actions will take about 8 work-hours and require parts costing $1,957, for a cost of $2,637 per product for Models S10 and S10–V. Wealso estimate that any necessary followon actions will take about 16 workhours and require parts costing $1,311, for a cost of $2,671 per product for Model S10–VT. We have no way of determining the number of products that may need these actions.
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.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on September 19, 2012 (77 FR 58052). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

CASA has received a number of Service Difficulty Reports regarding the pitot probe heater connector. The loss of pitot heat in Instrument Meteorological Condition (IMC) may lead to the loss of airspeed indication. This may lead to the loss of control of the
