Airworthiness Directives; Goodrich 

Evacuation Systems Approved Under 

Technical Standard Order (TSO) TSO– 

C69b and Installed on Airbus Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

Goodrich Evacuation Systems approved 

under TSO TSO–C69b and installed on 

Model A330–200 and –300 series 

airplanes, Model A340–200 and –300 

series airplanes, and Model A340–500 

and –600 series airplanes. That AD 

currently requires inspecting to 

determine the part number of the 

pressure relief valves on the affected 

Goodrich evacuation systems, and 

corrective action if necessary. This new 

AD requires inspecting to determine the 

part number of the pressure relief valves 

on the affected Goodrich evacuation 

systems and replacing certain pressure 

relief valves, and adds airplanes to the 

applicability. This AD was prompted by 

reports that during workshop testing, 

certain pressure relief valves, which 

were required by the existing AD, did 

not seal and allowed the pressure in 

certain slides/rafts to fall below the 

minimum raft mode pressure for the 

unit. We are issuing this AD to prevent 

loss of pressure in the escape slides/ 

rafts after an emergency evacuation, 

which could result in inadequate 

buoyancy to support the raft’s passenger 

capacity during ditching and increase 

the chance for injury to raft passengers. 

DATES: This AD is effective May 4, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of May 4, 2012.

SUPPLEMENTARY INFORMATION: 


sroberts on DSK5SPTVN1PROD with RULES
19070 Federal Register / Vol. 77, No. 62 / Friday, March 30, 2012 / Rules and Regulations 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 to supersede AD 

2007–23–01, Amendment 39–15247 (72 

FR 62568, November 6, 2007). That AD 

applies to the specified products. The 

SNPRM was published in the Federal 

Register on December 29, 2011 (76 FR 

81885). The original NPRM (76 FR 

15229, March 21, 2011) proposed to 

require inspecting to determine the part 

number of the pressure relief valves on 

the affected Goodrich evacuation 

systems and replacing certain pressure 

relief valves. The original NPRM also 

added Model A330–223F and –243F 

airplanes to the applicability. The 

SNPRM proposed to add Model A330– 

302 and –303 airplanes to the 

applicability. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the SNPRM 

(76 FR 81885, December 29, 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. 

Costs of Compliance 

We estimate that this AD affects 41 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection to determine part numbers ............ 1 work-hour × $85 per hour = $85 ................. $0 $85 $3,485 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need these replacements. 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Valve replacement ....................................................... 1 work-hour × $85 per hour = $85 ............................. $775 $860 per slide. 

According to the manufacturer, some 

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 

We have 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 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety.
