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

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: 

WREIER-aviles on DSK7SPTVN1PROD with RULES

63168 Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Rules and Regulations 

ESTIMATED 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 

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.

Cockpit Door Installations 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) 

that applies to the products listed above. 

This AD results from mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country to identify 

and correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as: 

During structural testing of the cockpit 

door, it was observed that the door lower 

hinge block rotated which resulted in 

disengagement of the mating hinge pin and 

excessive door deflection. The lower hinge 

block rotated because it was attached to its 

support structure with only one attachment 

bolt, which prevented it from reacting to any 

moment force. This condition, if not 

corrected, could result in breakage and 

uncontrolled release of the cockpit door 

under certain decompression situations. 

After incorporation of Modsum 8Q900267 

* * *, an operator reported a failure to 

complete the cockpit door removal function 

test. This condition, if not corrected, could 

result in the inability to remove the cockpit 

door for emergency egress. * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

November 16, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of November 16, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of Bombardier Service Bulletin 8–52–54,

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 was published in the Federal 

Register on June 8, 2011 (76 FR 33173), 

and proposed to supersede AD 2006– 

12–16, Amendment 39–14642 (71 FR 

34006, June 13, 2006). That NPRM 

proposed to correct an unsafe condition 

for the specified products. The MCAI 

states: 

During structural testing of the cockpit 

door, it was observed that the door lower 

hinge block rotated which resulted in 

disengagement of the mating hinge pin and 

excessive door deflection. The lower hinge 

block rotated because it was attached to its 

support structure with only one attachment 

bolt, which prevented it from reacting to any 

moment force. This condition, if not 

corrected, could result in breakage and 

uncontrolled release of the cockpit door 

under certain decompression situations. 

After incorporation of Modsum 8Q900267 

* * *, an operator reported a failure to 

complete the cockpit door removal function 

test. This condition, if not corrected, could 

result in the inability to remove the cockpit 

door for emergency egress. Therefore, * * * 

this [Canadian] directive is issued to require 

rework of the cockpit door striker plate and 

replacement of the latch block for the 

affected aircraft serial numbers. * * * 

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 

considered the comment received. The 

commenter supports the NPRM (76 FR

Conclusion 

We reviewed the available data, 

including the comment received, and 

WREIER-aviles on DSK7SPTVN1PROD with RULES
