Discussion

We received reports of damage found during maintenance inspections of the Diamond Model DA 40 airplanes equipped with a VCS installed per Premier Aircraft Service STC SA03674AT held by Premier Aircraft Services (originally held by DER Services) following DER Services Master Document List MDL–2006–020–1, Revision C, dated February 3, 2009; Revision D, dated April 22, 2009; Revision E, dated May 12, 2010; or Revision F, dated July 6, 2010. The damage included excessive wear in the VCS compressor mounting holes, mounting brackets, and the mounting bolt, and denting was found around the mounting bracket and compressor due to unintended relative motion. We are proposing this AD to remove the VCS mount, which could result in the air conditioner compressor disconnecting in the engine compartment. This condition could result in engine stoppage or additional damage to the engine.

Relevant Service Information

We reviewed Premier Aircraft Service Work Instruction PAS–WI–MSB–40– 2011–001, dated March 4, 2011; and Premier Aircraft Service Mandatory Service Bulletin No. PAS–MSB–40– 2011–001, dated March 4, 2011. The service information describes procedures for deactivation of the VCS Compressor and associated mounting hardware and the removal of the VCS installed per Premier Aircraft Service STC SA03674AT.

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 require deactivation of the VCS Compressor and removal of the VCS and the associated mounting hardware, except as discussed under ‘‘Differences Between the Proposed AD and the Service Information.’’ Differences Between the Proposed AD and the Service Information

The service information requires compliance prior to flight after effectivity of the service information. The service information also includes a reporting requirement.

This proposed AD requires a compliance time of within the next 100 hours time-in-service after installation of the STC or 30 days after the effective date of this proposed AD, whichever occurs later. We are not including the reporting requirement. Costs of Compliance

We estimate that this proposed AD affects 11 airplanes of U.S. registry.

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



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Remove the VCS compressor, deactivate system,

and revise weight and balance. 3 work-hours × $85 per hour = $255 Not applicable .................. $255 $2,805

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,


### 37686 Federal Register / Vol. 76, No. 124 / Tuesday, June 28, 2011 / Proposed Rules

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 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 this 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. List of Subjects in 14 CFR Part 39
