14 CFR Part 39

[Docket No. FAA-2011-0687; Directorate Identifier 2011-CE-017-AD; 
Amendment 39-16833; AD 2011-21-10]

Airworthiness Directives; Diamond Aircraft Industries GmbH 
Airplanes With Supplemental Type Certificate (STC) SA03674AT

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for Diamond 
Aircraft Industries GmbH Model (Diamond) DA 40 airplanes equipped with 
cabin air conditioning vapor cycle system (VCS) installed per STC 
SA03674AT held by Premier Aircraft Services (originally held by DER 
Services, Inc.) 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. This AD was prompted by reports of damage around the VCS 
compressor mounting areas found during maintenance inspections. This AD 
requires deactivation of the VCS, removal of the compressor and 
bracket, and revision to the airplane weight and balance. We are 
issuing this AD to correct the unsafe condition on these products.

DATES: This AD is effective November 16, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 16, 
2011.

SUPPLEMENTARY INFORMATION:

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 published in the Federal Register on June 28, 2011 (76 FR 
37684). That NPRM proposed to require removal of 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (76 FR 37684, June 28, 
2011) 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 and the addition of an optional terminating 
action after the compressor is removed which will allow for the 
reinstallation and reactivation of the air conditioning system. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 37684, June 28, 2011) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 11 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

 weight and balance.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

    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'' under 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.
