14 CFR Part 39 

[Docket No. FAA–2011–0223; Directorate 

Identifier 2010–NM–161–AD] 

RIN 2120–AA64 

Airworthiness Directives; Goodrich 

Evacuation Systems Approved Under 

Technical Standard Order (TSO) TSO– 

C69b and Installed on Airbus Model 

A330–200 and –300 Series Airplanes, 

Model A340–200 and –300 Series 

Airplanes, and Model A340–541 and 

–642 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to Goodrich evacuation 

systems approved under TSO–C69b and 

installed on certain Model A330–200 

and –300 series airplanes, Model A340– 

200 and –300 series airplanes, and 

Model A340–541 and –642 airplanes. 

The existing 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. Since 

we issued that AD, we have received 

reports that during workshop testing, 

certain pressure relief valves, which 

were required by the existing AD, did 

not seal and allowed the pressure in 

slides/rafts to fall below the minimum 

raft mode pressure for the unit. This 

proposed AD would require inspecting 

to determine the part number of the 

pressure relief valves on the affected 

Goodrich evacuation systems and 

replacing certain pressure relief valves. 

This proposed AD would also add 

airplanes to the applicability. We are 

proposing 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: We must receive comments on 

this proposed AD by May 5, 2011.

Discussion 

On October 27, 2007, we issued AD 

2007–23–01, Amendment 39–15247 (72 

FR 62568 November 6, 2007), for 

Goodrich evacuation systems approved 

under TSO–C69b and installed on 

certain Model A330–200 and –300 

series airplanes, Model A340–200 and 

–300 series airplanes, and Model A340– 

541 and –642 airplanes. That AD 

requires inspecting to determine the 

part number of the pressure relief valves 

on the affected Goodrich evacuation 

systems, and corrective action if 

necessary. That AD resulted from a 

report indicating that, during 

maintenance testing, the pressure relief 

valves on the affected Goodrich 

evacuation systems did not seal when 

activated, which caused the pressure in 

the escape slide/raft to drop below the 

minimum allowable raft mode pressure. 

We issued that 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. 

Actions Since Existing AD Was Issued 

Since we issued AD 2007–23–01, we 

have received reports that during 

workshop testing the pressure relief 

valves required by AD 2007–23–01 did 

not seal and allowed the pressure in 

some Model A330 and A340 series 

airplane slides/rafts to fall below the 

minimum raft mode pressure for the 

unit. 

Relevant Service Information 

We reviewed Goodrich Service 

Bulletin 7A1508/09/10/39–25–373, 

Revision 2, dated May 8, 2009; and 

Goodrich Service Bulletin 4A3928/ 

4A3934–25–374, Revision 1, dated May 

8, 2009. The service information 

describes, among other things, 

procedures for replacing certain 

pressure relief valves with new 

improved valves for applicable 

airplanes and doors as shown in the 

following table, and for marking the 

system identification placard on the girt.

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 retain none 

of the requirements of AD 2007–23–01. 

This proposed AD would require 

inspecting to determine the part number 

of the pressure relief valves on the 

affected Goodrich evacuation systems, 

replacing certain pressure relief valves 

with new improved valves, and marking 

the system identification placard on the 

girt of the replaced part. This proposed 

AD would also add Airbus Model 

A330–223F and –243F airplanes to the 

applicability. 

Differences Between the Proposed AD 

and the Service Information 

Goodrich Service Bulletin 4A3928/ 

4A3934–25–374, Revision 1, dated May 

8, 2009, specifies replacing certain firing 

pin cables with an improved firing pin 

cable, which is not included in this 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 41 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed 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 Up to $3,485. 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

proposed 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 proposed 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 

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 that the 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.
